FOOD WASTE REDUCTION-AN IMPERATIVE OPTION

Food wasting is a criminal act which must be condemned unequivocally. Mere fact that a country is wealthy does not confer upon it special rights to waste foods and such wastage is unconscionable looked from any angle. It is said that the world throws away food in such high quantities that it would be sufficient to feed 2 billion people, if saved, by taking a little bit more care by those who are blessed with access to plenty of foods. Food safety authorities world over have created an unenviable situation by mandating the industry to declare expiry date on each and every package of foods manufactured with the noble intention of helping consumers to avoid unsafe foods and face the adverse consequences of food poisoning. But the present system is not considered satisfactory since manufacturers routinely print expiry dates without any scientific basis and most foods even after the expiry date are considered safe though quality wise it may be marginally inferior. Ultimately it is the consumer who has to decide whether a food is good or bad through his sensory powers. Recent report that new smart freezers are being developed to help the consumer to forewarn about products dumped in the freezer and helping to remove old ones with expired dates already passed, is a welcome development. Here is a take on this electronic gadgetry which may hit the market soon. 

"Aside from the customer, the food industry includes many participants — from growers and producers to manufacturers who turn foods into products, to packaging companies, distributors, wholesalers, and retailers. The logistics are often complex: Food products can have many different ingredients, with multiple sources for each one. Perishable foods need cold storage and distribution that keeps them fresh. Food provenance, or where food is grown or made, also impacts the sustainability of the supply chain. Locally sourced food can reduce both transportation costs and emissions. With a global population expected to reach nine billion in 2050, efficiency is key in order to meet the increased demand for food. Food production consumes 10 percent of the U.S. energy budget and 50 percent of U.S. land, according to the Natural Resources Defense Council (NRDC). Yet, 40 percent of food in the U.S. goes uneaten. The U.S. wastes about 121 billion pounds of food each year, with some two-thirds of that going to landfills. At the same time, said the NRDC, one-in-six American households struggle to find enough food. Reducing losses by just 15 percent could feed an additional 25 million Americans every year, the group said. The Food Waste Reduction Alliance Project is a coalition working to re-route edible food to food banks. At the 2013 Sustainable Foods Summit in San Francisco, Bon Appetit Management Company said it's reducing food waste by changing meal sizes and menu options, while Whole Foods Market said it's composting its food waste in about 75 percent of its stores. Playing it Safe New food safety laws are also exerting pressures on food supply chains. The Food Safety Modernization Act (FSMA), signed into law by President Obama in 2011, makes regulators more responsible to prevent contamination, rather than just responding to it. The FSMA redefines how food is tracked, traced and monitored. As a result, new technologies are helping food companies trace the source, distribution path, and handling of ingredients in case of contamination and recalls.Temperature tags using Radio Frequency Identification (RFID) technology can provide continuous temperature data for perishable foods, enabling manufacturers and retailers to prevent spoilage and loss. IBM  used its RFID technology to create a smart freezer that can identify items nearing their expiration dates and alert staff when inventory is low on a particular item. Supermarket shoppers can also trace foods with the free HarvestMark Food Traceability App. Consumers can use a smart phone to scan codes on some three billion food items to see data on farmers and growing methods.With the help of new technology and smart changes to food management, companies can minimize safety risks, reduce waste and hunger, and help save the planet, too — a triple bottom line with far-reaching results for global sustainability".

More than the freezer, it is the refrigerator that needs such an app since frozen foods are relatively safe even after the expiry date linebut the temperature conditions in a refrigerator can definitely support bacterial and fungal growth after a few days of storage. If fresh produce packed properly are equipped with the appropriate RFID tags and smart refrigerators designed with the alert function, this will go a long way to help the consumers to save lot of foods. Such smart refrigerators can alert the house wives regarding the approaching expiry date so that the older foods are used in preference to fresher ones getting into the refrigerator.

WEALTH AND HEALTH FROM WASTE-NEW DEVELOPMENTAL PROGRAMS

Industrial wastes generated during processing of foods pose problems of disposal and in many countries anti-pollution laws forbid letting them out of the factory without reducing the BOD and solids content to very low levels. Take for instance the condition in a fruit processing unit where hardly 40-50% of the fruit is utilized for preparing various products and the waste generated include the solid wastes as well as enormous volume of water that need to be disposed off. While solid wastes have some demand for use as cattle feed, the liquid waste has very high BOD and requires to be treated for reducing its pollution load. It is in this context that any attempt to economically utilize these wastes will be beneficial to the industry. The international program recently launched with India as as partner to beneficiate the food industry wastes is indeed laudable provided the results are utilizable by the industry in these partner countries freely without any intellectual property restrictions.

"Primarily, the project focuses on utilising the molecules generated from food processing waste of mango, pomegranate, orange and rice bran. The ingredients have been used to develop aqua feeds and bakery items like biscuits, jams and jellies. In this regard, upscaling the research for the industry will be the next step in the right direction, since in India, a number of food companies are looking at the possibility of maximisng their potential.  Dr D Seenappa, chief scientific officer (IF) and university head, animal sciences and fisheries, inland fisheries division, UAS, Bangalore, informed FnB News, "The project is all about identifying and introducing innovative and industry-relevant approaches for the valorisation of fruit and cereal (rice bran) wastes. This is being currently achieved through holistic conversion into functional and health-benefitting beverages, foods and aqua feeds by means of environmentally and economically sustainable protocols and technologies. Production of food processing waste is being minimised and has helped to build a synergistic research programme between the EU and India to serve the future knowledge-based economies." Peel wastes of mango, orange, pomegranate and rice bran in powdered form have proven to show high levels of carotenoids, polyphenols, pectins, high fibre and carbohydrates. These have demonstrated health benefits with high antioxidant and immunity resistance properties. Peels which are been sourced from the food processing industry have been characterised, stabilised and assessed to be converted into powder form by food chemical engineers and scientists, according to Dr Seenappa. In addition, prebiotic and probiotic effects of the peels are evaluated. Mono dose products like fruit paste, snack foods, enriched beverages, breakfast cereals and biscuits have already been developed. From the EU, seven countries - Italy, the UK, Spain, Hungary, the Netherlands and Germany - have teamed up professionals with domain expertise in food and chemical engineering. India has five partners represented by the North East Institute of Science & Technology (NEIST), Jorhat, Assam, with the Indian scientific coordinator as P K Goswami; Euro India Research Centre (EIRC), Bangalore; University of Agricultural Sciences, Bangalore; Nature Fresh Logistics Pvt. Ltd, Pune; and Vaighai Agro Products Ltd, Madurai".  

The above project is neither the first one nor the last on waste utilization processing and there are good technologies already available in many areas that are being used to day by some industries improving their economic performance significantly. Pectin from apple wastes, essential oils from citrus wastes, alcohol from molasses, triacontanol from sugar cane mud, mango seed fat extraction, color fractions from beetroot, blue grape peel and others, rice bran oil extraction, wheat germ recovery for tocopherol rich oil, orange fruit fiber, oat bran for high fiber food, etc are classical examples of waste processing industry. One can hope that the new multi nation project will come out with technically and economically viable processes to supplement the present pool of such technologies.
