New cook chill manual launched

A detailed and comprehensive manual addressing cook chill for all involved in the food production chain is being released by the Australian Institute of Food Science and Technology (AIFST).

‘Cook Chill for Foodservice and Manufacturing: Guidelines for Safe Manufacturing, Storage and Distribution’ — also referred to as the Blue Book – is a vital update on the Australian Cook Chill Council’s book issued in 2000.

Responding to the changes in food safety practices and production developments for both the foodservice and retail sectors, the Blue Book is being launched at this year’s ‘Our Food Our Future’ 41st annual AIFST convention in July.

The Blue Book discusses what Cook Chill is, characteristics of the different Cook Chill systems, food safety support programs and ways to prepare a food safety (HAACP) plan.

Substantial appendices offer useful background information on food microbiology, pasteurisation, equipment used in production, storage and distribution, packaging materials, quality aspects and a glossary of industry terms. Additionally there is a host of websites listed for reference convenience.

AIFST president Peter Lancaster believes the Blue Book is an essential item for those in the industry.

“If you are involved in cook chill food production or planning in your foodservice operation, in manufacturing, or in planning ready-to-eat chilled foods for retail sale, then you cannot afford to be without this publication,” he said.

The 41st Annual AIFST Convention holds under the microscope aspects of the food industry including regulatory issues, business development and the future of food. Conveniently, the foodpro expo is being held adjacent during the same period.

Focusing on the role of education and training in the food industry will be respected international speakers, Frank Yiannas (manager of Walt Disney World’s food safety and health department) and Professor John Floros (president of the US Institute of Food Technologists).

AIFST was established in 1967 to represent individuals involved in the Australian food and allied industries. Committed to building professional standing in the sector, AIFST has developed a strong reputation for facilitating networking, communication and education in the food industry.

The 41st annual AIFST Convention will be held at the Sydney Exhibition and Convention Centre, Darling Harbour from 21 — 24 July 2008.

Nanofood for the future

Once a far-fetched fantasy a long way into the future, nanotechnology is set to have a huge impact on our lives in the here and now. With developments of materials and devices that can monitor blood, detect environmental pollutants and store energy better, nanotech is becoming an integral part of our ever-changing world.

One of nanotech’s most immediate effects will be felt in our food with companies worldwide conducting research using nanotechnology to develop foods with new possibilities in tastes, textures, packaging and enhanced nutrient absorption.

A recent report by International lobby group, The Friends of the Earth (FoE) found that 104 foods, food contact materials and agricultural products containing nanomaterials are now on sale internationally.

Nanotechnology is now used to manufacture some nutritional supplements, flavour and colour additives, food packaging, cling wrap, containers and chemicals used in agriculture.

Some products containing nano-sized particles are already on the market. In America and Europe, nano-sized ingredients have been added to some fruit juices, processed meats, diet milkshakes and baby food.

“We know manufactured nanomaterials are already in some products found on Australian supermarket shelves and used in Australian kitchens,” FoE Nanotechnology Project’s report co-author Georgia Miller said.

“Packaging for Cadbury chocolates, antibacterial kitchen wipes and cleaning sprays, and refrigerators sold by Samsung, Hitachi and LG Electronics now contain manufactured nanomaterials.”

The nanofood sector is led by the US, followed by Japan and China. Asian countries, particularly China, are expected to be the biggest market for nanofood by 2010.

Food packaging using nanotechnology is more advanced than nanofoods, with products on the market that incorporate nanomaterials that scavenge oxygen, fight bacteria, keep in moisture or sense the state of the food.

Plastic incorporating nanoparticles of clay or oxides of metals such as zinc and titanium have already been used to package meats, cheese, confectionery, beer, fruit juice and soft drink overseas.

The fact that nano additives are already part of our products is leading to growing calls for better safety assessment and regulation of nanotechnology in food.

According to report co-author Dr Rye Senjen, the worry is that “Australian laws do not require manufacturers to declare whether or not their products contain manufactured nanomaterials, or to conduct new safety tests on nano ingredients.

“Australian regulators have no way to know how many nano foods may be on Australian supermarket shelves and no way to check whether or not they are safe.”

The UK government’s Central Science Laboratory’s Dr Qasim Chaudhry, says engineered nanosized particles and other structures are used to develop new tastes, textures, and nutritional qualities, as well as improving shelf life and traceability of food products.

The main concern to consumers from nanoparticles in food packaging is through their migration into food and drinks, says Dr Chaudhry. Currently, however, there is not enough information to adequately assess the risk of these additives and ingredients.

With this uncertainty in mind, hasty action should be avoided, especially where food and drinks containing nano-ingredients are likely to be consumed in large quantities by a significat proportion of the population.

Size counts

Complicating the issue is an ongoing debate about the exact size of particles that have the potential to cross into the body’s cells.

While the nanoscale usually refers to structures under 100 nanometres, FoE points to evidence that structures of 300 nanometres can actually also present risks and should be checked for safety.

It has also been shown that particles smaller than 70 nanometres can reach the nucleus of the cell and possibly disrupt the DNA.

Gut reaction

Because current regulations do not fully cover nanotechnology in food, the European food science professional body, the Institute of Food Science and Technology, recently recommended that nanoparticles be treated as new, potentially harmful materials, until testing proves otherwise.

An expert in international nanotechnology regulation, Monash University Professor Graeme Hodge, warns against a “gut reaction” to nanotechnology without considering and assessing all the evidence.

“Don’t panic up front,” he says, adding that the use of nanotechnology in some areas will be “quite benign.” According to the Professor, a host of standards guarding food safety are already in place. “We’re not coming at the question of nanotechnology from a blank slate,” he explained.

Professor Hodge has helped the Australian government to prepare a report on nanotechnology to identify possible gaps in Australian regulations. Australia is one of the few countries to have done this.

However, he does say that it is too early to know if new regulations are really required, especially since international standard-setting bodies are only now officially defining the characteristics of nanomaterials.

A federal health department statement on behalf of Food Standards Australia New Zealand (FSANZ) said that “no policy has been developed in regards to a specific regulatory response to nanotechnology.

“FSANZ is not aware, nor has it been made aware, of any commercially sold foods in Australia that have been developed using nanotechnology.”

The statement says FSANZ is gathering information and discussing the food safety implications of nanotechnology with international bodies and is yet to determine if a risk assessment is required for nanotechnology in foods.

The statement continues by confirming that “robust regulatory arrangements to ensure the safety of food” are in place.

To nano or not to nano?

Few studies have been carried out on the toxic effects of nanoparticles, and most deal with the risks of breathing them in, rather than consuming them, says Dr Chaudhry.

Although one of the benefits of nano-technology may be to increase absorption of nutrients from food, there are infinite unknown consequences, such as a possible change in the balance of nutrients in the body.

“It is also of concern that the introduction into foods of nanoparticles designed to carry dietary supplements could lead to the introduction of foreign substances into the blood,” he explained.

An example of this problem is Nanosilver which is good at killing bacteria. However, no research has been published about the possible effects of Nanosilver on the beneficial bacteria in our bodies.

“There is an urgent need for research into the behaviour of foodstuffs, both manipulated and processed at the nanoscale and the properties of manufactured nanoparticles introduced into foods whether deliberately or as the result of contamination.”

Apart from the many safety issues and questions around this modern marvel, one thing is certain – nanofood will make it even more unlikely that people will eat fresh, sustainably produced food, bringing with it an endless array of debates about priorities for our modern lifestyles.

Microwave technology for food processing

Industrial Microwave Systems, L.L.C., the producer of patented microwave systems, announces the first commercial process licensing and installation of its Cylindrical Heating System. This system, developed by IMS, employs an aseptic process created through the joint efforts of IMS, North Carolina State University Department of Food Science, and the US Department of Agriculture’s (USDA) Agricultural Research Service (South Atlantic Area).

This new microwave technology, which features a unique, ultra-rapid method of heating aseptic and extended shelf life pumpable food products in a tube, has been installed for Yamco, L.L.C., a North Carolina company. Yamco will officially open a new food manufacturing facility on 26 March, 2008, and showcase this technology for the processing of low acid sweet potatoes.

The IMS Cylindrical Heating System enables liquid, semi-liquid, and pumpable foods and beverages to be uniformly and volumetrically heated on a continuous flow basis while pumped through a tube. The patented technology employed by the IMS cylindrical heater provides uniform spatial and temporal delivery of high-intensity thermal energy to the flowing components, solving the problem of ‘hot spots’ in traditional thermal processing technology.

This results in benefits that allow manufacturers currently using conventional heat exchangers an opportunity to greatly improve product quality while reducing floor space and increasing operational efficiency.

For Yamco, the installation of the IMS Cylindrical Heating System will enable it to produce a superior, nutrient-rich, shelf-stable sweet potato product that can be sold as a premium food ingredient for use in products such as baked goods, nutraceuticals, and infant formulations. Because the pumpable food product is heated so quickly and evenly, the unique thermal process allows for ultra-rapid sterilization with minimal product degradation.

Extensive testing of the heating system and process at North Carolina State University has ensured the delivery of an aseptic sweet potato puree that exhibits maximal nutrient and colour retention and minimal flavour loss. The capability of producing such a superior sweet potato product presents an advantageous opportunity for North Carolina farmers, who account for 40% of the United States’ annual sweet potato production.

A joint U.S. patent for the ultra-rapid heating process has been filed by IMS, North Carolina State University, and the USDA. The three parties worked together to test and develop the total aseptic process and packaging system. When issued, the patent, as it pertains to sweet potato puree processing, will be exclusively licensed to Yamco.

Baby food processors return to the simple life

There has been an evolution in the baby food segment in recent years.

Highly processed varieties are being replaced with healthier products, and smaller companies are emerging to tackle the growing organics sector.

The format of baby food is also changing, with newer companies moving away from conventional canning and developing chilled and frozen ranges that resemble home-cooked meals while still being a convenient alternative.

These processing methods claim to keep the product fresher and safer for the consumer.

Today’s baby food manufacturing is comprised of more simple, conventional cooking methods rather than complex, sophisticated processing systems.

“From a processing perspective, it seems like baby food manufacturers are going backwards instead of forwards in the sense that cooking is becoming less about high-tech equipment and processes,” Boost Foods director and chef Geoff McEwan said.

“I think the days of cans and bottles are gone and that the future is fresh, which means less processing.”

Gold Peg, a supplier of direct steam injection continuous cooking technology and systems, believes they are meeting the demands of baby food manufacturers that want to maintain the appearance and flavour of ingredients for appeal and taste, while guaranteeing safety.

“The RotaTherm cooker is energy efficient and decreases the impact on ingredients to facilitate an organic, home-cooked appearance, while still maintaining high bacteriological kill,” Gold Peg marketing manager Paula Bell said.

Processing

The simple, home-style approach to processing baby food is governed by two main considerations: nutritional value and food safety.

The taste and appearance of the food are important.

The focus on nutrition in baby food manufacturing is of particular importance, given that babies require higher levels of nutrients in their diets than adults to facilitate normal growth and development.

This and parents’ desire to maintain their babies optimum health has spurred an increase in the organics baby food sector, which Woolworths says now comprises 15% of the Australian baby grocery market, and has also impacted on the format and processing of baby food.

Cooking plays a major part in the retention of nutrient value in raw fruit and vegetables.

A book written by the Department of Food Science and Human Nutrition at Iowa State University, USA, (1999) reported that food processing contributed to the health, safety, taste and shelf stability of a product though could also be detrimental to the nutritional quality of the food.

The time and temperature of processing, product composition and storage are all factors that substantially impact on the vitamin status of food, the book stated.

For instance in certain foods blanching, milling and extrusion can result in the loss of vitamins and minerals.

Chilled ready-to-eat baby food

Boost Foods, an organic baby food company, employs a manual, home-style cooking method for its Baby Boost brand.

The company was started in order to provide consumers with a convenient alternative to home cooked food that met similar taste and nutritional standards.

“The initial challenge we faced was how to replicate what is done at home by retaining all the vitamins and nutrients babies needs, and produce it on a commercial scale,” explained Geoff McEwan.

The result was a range of chilled baby food made from fresh produce.

Boost Foods takes a manual approach to cooking, utilising a thermal processing method in a steam jacketed kettle.

This is beneficial as it is able to monitor the profile of the food during the entire process, controlling the temperature and overall quality of the end product.

“We have adopted the ‘less is more’ approach and cook the product as little as possible,” McEwan said.

Thermal processing heats the product from underneath and from the side walls, resulting in fast cooking times and the retention of colour and flavour.

Minimal water is used for cooking which means nutrients are not drained with the water at the end.

The food is packaged in a soft pouch that has a shelf life of 100 days.

The pouch can be heated and the food served directly from it.

Food safety is ensured by pasteurising the product, as opposed to adding artificial preservatives and stabilisers.

Boost Foods maintains its labour-intensive cooking procedure still allows it to produce high volumes of product, but says it involves working harder for longer.

“Taking a manual approach as opposed to a mechanical may be more labour intensive but it’s also essential in ensuring the end product satisfies high nutritional and taste standards,” McEwan said.

Snap-freezing

Organic baby food company, Organic Bubs, also utilises conventional, manual processing methods to ensure its products boast high nutritional and safety standards.

The manual handling of the product and use of smaller, less industrial equipment allows the company to exercise control over the cooking temperature, as well as the taste and appearance of the product.

“We know there is sophisticated, industrial equipment on the market but we have a philosophy that if the equipment interferes with our quality standards then we will continue to do it by hand, despite the labour involved,” Organics Bubs director Anthony Gauldi said.

The innovative format of the baby food, being snap frozen, is also central to the company’s focus on nutrition and safety.

Having started manufacturing in May this year, Organic Bubs is currently the only company in Australia offering snap-frozen meals.

Frozen ready meals in the adult food category have been around for years, though have been slow to be taken up by Australian manufacturers in the baby food market given the perception by consumers that frozen is not healthy because it is not fresh.

Organics Bubs, on the other hand, believe that frozen is better than most fresh processing.

“If you can get fresh produce, process it straight away and blast freeze it, you can preserve the colour of the product, its nutrient content and its shelf life,” Gualdi said.

Blast freezing involves bringing down the temperature of the cooked food rapidly, from approximately 80 degrees to -22 degrees.

After cooking the product in steam injected kettles, the mix is put through a mouli to ensure there are no lumps in the product that the baby will not be able to swallow, and it is then manually scooped into PP5-grade plastic tubs.

One of the main benefits of steam injection cooking is that the product can be cooked at lower temperatures as it is cooked evenly throughout the whole pot and agitates as it goes.

“Making sure the food is not heated to high levels is essential to ensure more nutrients are kept in,” Gualdi said.

This method differs to that used by parents at home, as cooking on a stove involves heating food from the bottom up, but the end result — in terms of the taste, appearance and nutritional quality of the food — is similar due to Organic Bub’s hands-on approach.

Shelf-stable baby food

Heinz Australia, Australia’s leading baby food manufacturer comprising 78.9% of the wet baby food market, says its food recipes and the way they are developed also resemble home-made methods.

The company develops its recipes in 2kg pots which are only moved to 2000kg kettles for production once they have met its taste and nutritional standards.

Heinz employs a batch cooking method using continuous steam injection, with a specific volume of the recipe being cooked before being filled into individual vacuum-sealed glass jars.

A retorting process is then employed to finish the cooking and seal in jars.

Unlike conventional retort cooking, which often involves high-pressure steam to cook the product inside a can or jar and can result in over-cooking, the fact that most of the cooking is done in a kettle before filling results in the retorting process being less severe and helps to retain nutrients.

“Batch cooking ensures a high level of accuracy and control through carefully monitoring recipe preparation as well as ingredients and packaging components,” a Heinz spokesperson said.

The product is sealed in air-tight jars which preserves the product without adding anything artificial and prevents microbial contamination.

If stored in a cool, dry cupboard or pantry, the jarred baby food is shelf stable for at least three years.

The health and wellness trend has lead to new product development at Heinz under its Pure Start program.

Products in this range contain fresh produce, meat and grains, no preservatives, salt, colours or artificial flavours and now include varieties such as organics and vegetarian.

Consumer and retailer demand for less processed, more natural, and yet convenient baby food has resulted in a trend towards simple, conventional processing methods to ensure products retain high levels of nutrition and safety.

The types of baby food on offer will continue to evolve in line with consumer perceptions and tastes, and food manufacturers will continue to search for the best methods of meeting these demands, even if that involves less and less processing.

Softfruit launched in UK

Australian research and development company, Byron Food Science, has announced the commercialisation of its SOFTFRUIT technology in the UK.

Softfruit technology allows the economical production water activity controlled real fruits and these products are now available in Australia and New Zealand through Byron.

According to the company, the novel technology preserves the natural textures, flavours and colours of real fruit during the manufacturing process.

The process is fast, produces no by-products and can be manufactured close to the market place all year round.

The Byron technology enables the water activity of the fruit to match its specific application, whether added to dry breakfast cereals, high-moisture bakery items, dairy products, wet pie fillings or additions to sausage fillings.

Due to the efficiency of the process, functional food products that contain no added sugar, completely natural ingredients or pro- and prebiotic properties can be formulated.

Native fruits rich in antioxidants

A recent study by Food Science Australia (FSA) has revealed the high antioxidant levels in twelve native Australian fruits which could benefit the food and functional food industries.

Published in the journal Innovative Food Science & Emerging Technologies, the fruits were shown to be rich sources of antioxidants with stronger radical scavenging activities than blueberries, which are renowned for their high antioxidant properties.

The fruits include:

  • Kakadu plum
  • Illawarra plum
  • Burdekin plum
  • Davidson’s plum
  • Riberry
  • Red and yellow finger limes
  • Tasmanian pepper
  • Brush cherry
  • Cedar Bay cherry
  • Muntries
  • Molucca raspberry

“Compared to blueberries’ TEAC value of 39.45 trolox equivalents per gram, Kakadu plum and Burdekin plum had TEAC values of 204.8 and 192.0 trolox equivalents per gram,” co-author and FSA researcher Dr Michael Netzel said.

According to FSA, using native Australian fruits as a source of phytochemicals for use in foods could have many benefits for the food and functional food industries, and studies to identify additional antioxidant compounds as well as clinical trials for testing the fruits’ bioactivity are in progress.

“Finding unique food ingredients and flavours with health-promoting properties is a key market requirement these days,” FSA’s research team leader Izabela Konczak said.

“And by encouraging growers to cultivate native fruits, we are also contributing to the growing need to ensure agriculture becomes more sustainable.”

The research supports CSIRO efforts to realise the potential of Australia’s fledgling native food industry, currently estimated to be worth $14 million annually.

It is the first scientific study of the fruits as a source of antioxidants, confirming preliminary results published in the Journal of Agricultural and Food Chemistry in 2006.
