Jensen, J. Graham and Donald L. Graham, which were revised by Donald L. The term food industries covers a series of industrial activities directed at the processing, conversion, preparation, preservation and packaging of foodstuffs see table The raw materials used are generally of vegetable or animal origin and produced by agriculture, farming, breeding and fishing.
This article provides an overview of the complex of food industries. Other articles in this chapter and Encyclopaedia deal with particular food industry sectors and particular hazards.
Many food industries depend almost entirely on local agriculture or fishing. In the past, this meant seasonal production and hiring of seasonal workers. Improvements in food processing and preservation technologies have taken some of the pressure off workers to process food quickly to prevent spoilage.
This has resulted in a decrease in seasonal employment fluctuations. However, certain industries still have seasonal activities, such as fresh fruit and vegetable processing and increases in production of baked goods, chocolate and so forth for holiday seasons.
Seasonal workers are often women and foreign workers. Much of this increase can be attributed to an increased demand for processed food and drink, especially in developing countries where the market has not yet been saturated.
This increase in output of food and drink products, however, has not resulted in increased employment because of intensified competition, which has resulted in decreased employment in many food industries, especially in industrialized countries. This is due to increased productivity and mechanization in many of these industries. Demographic pressure, uneven distribution of agricultural resources and the need to insure preservation of food products to facilitate their better distribution explain the rapid technical evolution in the food industries.
Constant economic and marketing pressures drive the industry to provide new and different products for market, while other operations may make the same product in the same way for decades. Even highly industrialized facilities often resort to seemingly archaic techniques when starting new products or processes. In practice, to satisfy population requirements, there is a need not only for a sufficient quantity of foodstuffs, which presupposes an increase of production, but also strict control of sanitation to obtain the quality essential to maintain the health of the community.
Only modernization of techniques justified by production volumes in a stable production environment will eliminate manual handling hazards. In spite of the extreme diversity of the food industries, the preparation processes can be divided into handling and storage of raw materials, extraction, processing, preservation and packaging. Manipulation of the raw materials, the ingredients during processing and the finished products is varied and diverse.
Mechanical handling may involve: self-propelled in-plant transport with or without palletization or super or bulk sacks often containing several thousand pounds of dry powder material ; conveyor belts e. Storage of raw materials is most important in a seasonal industry e.
It is usually done in silos, tanks, cellars, bins or cold stores. Storage of the finished products varies according to their nature liquid or solid , the method of preserving and the method of packaging loose, in sack or super sack, in bundles, boxes or bottles ; and the respective premises must be planned to suit the conditions of handling and preserving traffic aisles, ease of access, temperature and humidity suited to product, cold-storage installations.
Commodities may be held in oxygen-deficient atmospheres or under fumigation while in storage or just before shipment. To extract a specific food product from fruit, cereals or liquids, any of the following methods may be used: crushing, pounding or grinding, extraction by heat direct or indirect , extraction by solvents, drying and filtration.
In other cases it may be the actual extraction process, as in flour milling. Heat can be used directly as a means of preparation by extraction, as in roasting e. Oils can be extracted equally well by combining and mixing the crushed fruit with solvents that are later eliminated by filtering and reheating.
The separation of liquid products is carried out by centrifuging turbines in a sugar refinery or by filtering through filter presses in breweries and in oil and fat production. Operations in processing food products are extremely varied and can be described only after individual study of each industry, but the following general procedures are used: fermentation, cooking, dehydration and distillation.
Fermentation, obtained usually by addition of a micro-organism to the previously prepared product, is practiced in bakeries, breweries, the wine and spirits industry and the cheese products industry. Cooking occurs in many manufacturing operations: canning and preserving of meat, fish, vegetables and fruits; ready-to-serve meat-processing plants e.
In other cases, cooking is done in a vacuum-sealed container and produces a concentration of the product e. Besides the drying of products by the sun, as with many tropical fruits, dehydration can be carried out in hot air fixed dryers or drying tunnels , by contact on a drying drum heated by steam, such as in the instant-coffee industry and the tea industry , vacuum drying often combined with filtering and lyophilization freeze drying , where the product is first frozen solid and then dried by vacuum in a heated chamber.
Distillation is used in the making of spirits. The fermented liquid, treated to separate grain or fruit, is vaporized in a still; the condensed vapour is then collected as liquid ethyl alcohol. Briefly, the first three methods destroy microbial life; the latter merely inhibit growth. Raw ingredients such as fish and meat, fruit or vegetables are taken fresh and preserved by one of the above methods, or a mixture of different foods are processed to form a product or dish, which is then preserved.
Such products include soups, meat dishes and puddings. Food preservation goes back to the last Ice Age, about 15, BC, when Cro-Magnon humans discovered for the first time a way of preserving food by smoking it.
The evidence for this lies in the caves at Les Eyzies in the Dordogne in France, where this way of life is well portrayed in carvings, engravings and paintings. From then to the present day, although many methods have been used and still are, heat remains one of the principal cornerstones of food preservation. High-temperature processes can destroy bacteria, depending on the cooking temperature and duration. Sterilization mainly used in canneries involves submitting the already canned product to the action of steam, generally in a closed container such as an autoclave or continuous cooker.
Smoking is carried out mainly on fish, ham and bacon, assuring dehydration and giving a distinctive flavor. Ionizing radiation sterilization is used heavily on spices in some countries to reduce wastage and spoilage. However, sterilizing canned foods with radiation requires such high dosage that unacceptable flavours and odours result. Microwave sterilization is another type of electromagnetic emission that is currently finding use in the food industry.
It is used for rapidly thawing raw frozen ingredients before further processing, as well as for heating frozen cooked foods in 2 to 3 minutes. Such a method, with its low moisture content loss, preserves the appearance and flavour of the food. Drying is a common preservation process. Sun drying is the oldest and most widely used method of food preservation. Today foodstuffs may be dried in air, superheated steam, in vacuum, in inert gas and by direct application of heat.
Many types of dryers exist, the particular type being dependent on the nature of the material, the desired form of finished product and so on.
Dehydration is a process in which heat is transferred into the water in the food, which is vapourized. The water vapour is then removed.
Low-temperature processes involve storage in a cold store the temperature determined by the nature of the products , freezing and deep-freezing, which allows foodstuffs to be preserved in their naturally fresh state, by various methods of slow or rapid freezing.
With freeze drying, the material to be dried is frozen and placed in a sealed chamber. The chamber pressure is reduced and maintained at a value below 1 mm Hg. Heat is applied to the material, the surface ice heats up and the resultant water vapour is drawn off by the vacuum system. As the ice boundary recedes into the material, the ice sublimes in situ and the water percolates to the surface through the pore structure of the material. The technology, which is difficult, is a spin-off from space travel.
Open-shelf stability is achieved by suitable control of acidity, redox potential, humectants and preservatives. Most developments to date have been in foods for pet animals. Whatever the preservation process, the food to be preserved has first to be prepared. Meat preservation involves a butchery department; fish needs cleaning and gutting, filleting, curing and so on. Before fruit and vegetables can be preserved they have to be washed, cleaned, blanched, perhaps graded, peeled, stalked, shelled and stoned.
Many of the ingredients have to be chopped, sliced, minced or pressed. There are many methods of packaging food, including canning, aseptic packaging and frozen packaging. The conventional method of canning is based on the original work of Appert in France, for which in the French government awarded him a prize of 12, francs.
He preserved food in glass containers. In Dartford, England, in , Donkin and Hall set up the first cannery using tinned iron containers. Today the world uses several million tonnes of tinplate annually for the canning industry, and a substantial amount of preserved food is packed into glass jars.
The process of canning consists of taking cleaned food, raw or partly cooked but not intentionally sterilized, and packing it into a can that is sealed with a lid. The can is then heated, usually by steam under pressure, to a certain temperature for a period of time to allow penetration of the heat to the centre of the can, destroying the microbial life. The can is then cooled in air or chlorinated water, after which it is labelled and packed.
Changes in processing have occurred over the years. Continuous sterilizers cause less damage to cans by impact and allow cooling and drying in a closed atmosphere. Foods can also be heat preserved in retortable pouches. These are bags of small cross-sectional area made from laminates of aluminium and heat-sealable plastics.
The process is the same as for conventional canning, but better taste properties are claimed for the products because sterilization times can be reduced. Very careful control of the retorting process is essential to avoid damage to the heat seals with subsequent bacterial spoilage. There have been recent developments in the aseptic packaging of food. The process is fundamentally different from conventional canning.
In the aseptic method the food container and closure are sterilized separately, and the filling and closing are done in a sterile atmosphere. Product quality is optimal because heat treatment of the foodstuff can be controlled precisely and is independent of the size or material of the container.
Of concern is employee exposure to the sterilizing agents. It is likely that the method will become more widely used because overall it should result in energy savings. Developments on particulate foodstuffs will follow. One likely benefit in food factories will be the reduction of noise if rigid metallic containers are replaced.
Such containers may also cause problems by contaminating preserved food with lead and tin. These are minimized by new-type two-piece containers drawn from lacquered tinplate and three-piece containers with welded instead of soldered side seams. The frozen food industry utilizes all methods of deep-freezing fresh food at temperatures below their freezing point, thus forming ice crystals in the watery tissues.
The food may be frozen raw or partially cooked e. Food for freezing must be in prime condition and prepared under strict hygienic control.

Starch sugars are a group of starch derivatives, which find significant application as natural sweeteners in foodstuff and beverages or as components in other fields, for instance in pharmaceuticals and cosmetics. In the bioprocess industry, they serve as a substrate to manufacture fermentation products. On this page you can find out how starch sugars are produced and how Vogelbusch can contribute to setting up a starch sweetener plant. Starch is a carbohydrate, which is extracted from agricultural raw materials such as corn, wheat, sorghum milo , cassava tapioca in a wet milling plant.

Historically, most starch containing crops were used for direct human consumption. This changed during the s and s, when industrial farming systems became popular for producing meat, milk and eggs on the basis of compounded feed that was largely made up by grains and soy beans. Such use became particularly important when economic growth in Asia accelerated as a result of the liberalization of the Chinese economic system. Standards of living increased and the demand for meat developed fast and drove a rapid and massive expansion of the use of cereals for feeding.SEE VIDEO BY TOPIC: Starch Manufacturing Process
The process of making corn into ethanol is a multistep process. The first step is milling the corn. It can be done by dry milling or wet milling. Figures 7. For wet milling, the corn kernels are broken down into starch, fiber, corn germ, and protein by heating in sulfurous acid solution for 2 days.
Glucose syrups are purified concentrated aqueous solutions of soluble saccharides obtained from starch with a dextrose equivalent above Starch milk is successively hydrolysed, demineralized, decolorized and then concentrated to obtain glucose syrups. Hydrolysis can be acidic or enzymatic. The common hydrolysis process consists of a liquefaction of starch, followed by a saccharification, using an appropriate cocktail of enzymes according to the desired sugar spectrum in manufacturing. Glucose syrups provide unique combinations of physical and chemical properties widely used in the food industry. In confectionery candy, chewing gums, jellies , glucose syrups are essential ingredients that provide viscosity, anti-crystallizing and sweetening power. When talking about sweet bakery cakes, biscuits and cereal-based products, glucose syrups bring body, bulk and optimise sweetness. In ice creams, they enhance the smoothness of the finished products.
Corn syrup is one of several natural sweeteners derived from corn starch. It is used in a wide variety of food products including cookies, crackers, catsups, cereals, flavored yogurts, ice cream, preserved meats, canned fruits and vegetables, soups, beers, and many others. It is also used to provide an acceptable taste to sealable envelopes, stamps, and aspirins. One derivative of corn syrup is high fructose corn syrup, which is as sweet as sugar and is often used in soft drinks. Corn syrup may be shipped and used as a thick liquid or it may be dried to form a crystalline powder.
