Food Processing and Preservation, branch of manufacturing
that transforms raw animal, vegetable, or marine materials into tasty,
nutritious, and safe food products. The industry has its roots in
ancient times, as humans have always needed to obtain food and store a
portion for later use. Prehistoric humans may have dried fruits in the
sun and stored meat in cold areas, such as caves. The modern food
processing and preservation industry was born in 1809, when French chef
and inventor Nicholas Appert, searching for a better way to provide food
for Napoleon's army, devised a method for sterilizing food in tightly
sealed glass bottles.
Today a wide variety of methods are available to maintain and enhance
the appearance and taste of food. Food processing and preservation
methods also create products that are convenient for consumers, such as
products that are ready to eat or require minimal preparation and
cooking. Combining these methods with modern distribution networks makes
seasonal crops available year-round in grocery stores all over the
world.
PROCESSING AND PRESERVATION METHODS
Food processing encompasses all the steps that food goes through from
the time it is harvested to the time it arrives on supermarket shelves.
At simplest, processing may involve only picking, sorting, and washing
fruits and vegetables before they are sent to market. Some processing
methods convert raw materials into a different form or change the nature
of the product, as in the manufacture of sugar from sugar beets, oil
from corn or olives, or cheese from milk. Processing may also involve an
extremely complex set of techniques and ingredients to create
ready-to-eat convenience foods.
Food preservation refers specifically to the processing techniques that
are used to keep food from spoiling. Spoilage is any change that makes
food unfit for consumption, and includes chemical and physical changes,
such as bruising and browning; infestation by insects or other pests; or
growth of microorganisms, such as bacteria, yeast, and molds.
Some food preservation techniques destroy enzymes, proteins that are
present in all raw foods, which are responsible for the chemical and
physical changes that naturally occur after harvesting. Food
preservation techniques also help eliminate the moisture or temperature
conditions that are favorable for the growth of microorganisms. As they
multiply and grow, microorganisms are capable of causing food-borne
illness. They also break down foods, producing unpleasant changes in
taste, texture, and appearance-changes that we recognize as spoilage.
Although people have known about spoilage and some preservation methods
to prevent it for centuries, it was only in 1857 that French chemist
Louis Pasteur demonstrated the role of microorganisms in the process.
Curing is one of the oldest forms of food preservation. It is used to
preserve meat and fish, yielding common products such as bacon, ham,
frankfurters, and corned beef. Curing involves adding some combination
of salt, sugar, spices, vinegar, or sodium nitrite to animal foods.
Smoking, a flavoring technique and preservation method, is another
ancient technique that is commonly used with curing. Smoking involves
cooking meat or fish very slowly over a low wood fire. Curing and
smoking preserve food by binding or removing water so that it is not
available for the growth of microorganisms. These methods impart a
distinctive color and flavor to food and, in some cases, eliminate the
need for refrigeration. Some studies, however, show that curing agents
such as sodium nitrite may combine with other chemicals to form
cancer-causing nitrosamines. In addition, cured products tend to be very
salty, and the sodium in salty foods has been linked to high blood
pressure. Smoked meats and fish may contain toxic and even carcinogenic
compounds that they absorb from wood smoke.
Drying Drying has been used to preserve food by cultures throughout the
world since prehistoric times, when people learned that dried foods-for
example, fruits left out in the sun-remain wholesome for long periods.
In modern times, the dried foods industry greatly expanded after World
War II (1939-1945) but remains restricted to certain foods, including
milk, soup, eggs, fruits, yeast, some meats, and instant coffee, that
are particularly suited to the process. Three basic methods of drying
are used today: sun drying, a traditional method in which foods dry
naturally in the sun; hot air drying, in which foods are exposed to a
blast of hot air; and freeze-drying, in which frozen food is placed in a
vacuum chamber to draw out the water. Removing the water preserves food
because microorganisms need water to grow and food enzymes cannot work
without a watery environment. Removing the water also decreases the
weight and volume of foods, thereby reducing transportation and storage
costs. However, dried foods may be less convenient for consumers because
most must be rehydrated before consumption. In addition, most dried
foods only reabsorb about two-thirds of their original water content,
leaving the rehydrated product with a tougher, chewier texture than the
original. Some scientists and consumer groups have raised concerns about
the sulfites commonly added to fruits before drying to prevent browning.
These chemicals may cause severe allergic reactions in people with
asthma or other people sensitive to the chemicals.
In freeze-drying, frozen food is placed in a special vacuum cabinet.
There, water escapes from the food by sublimation, a process in which
ice changes from a solid directly to a vapor without first becoming a
liquid. Freeze-dried foods retain their original flavor, texture, and
nutrients upon rehydration but must be packaged in moisture-proof,
hermetically sealed containers. Freeze-drying is an expensive process
used for such products as instant coffee, dried soup mixes,
strawberries, mushrooms, and shrimp.
Canning Canning is used to preserve a wide variety of foods, including
soups, sauces, fruits, vegetables, juices, meats, fish, and some dairy
products. Canning preserves food by heating it in airtight,
vacuum-sealed containers. The can is filled with food, and air is pumped
out of the space remaining at the top of the can to form a vacuum. The
container is sealed, heated in a cooker called a retort, and then cooled
to prevent overcooking of the food inside. This process removes oxygen,
destroys enzymes involved in food spoilage, and kills most
microorganisms that may be present in the food.

Canned foods are popular because they are already partially prepared and
cooked, can be stored without refrigeration for long periods, and are
generally low in cost. However, because of the high temperatures
required for sterilization, canning affects the color, texture, flavor,
and nutrient content of foods. Fat-soluble vitamins and minerals are
barely affected by heat processing, but water-soluble vitamins,
especially thiamine, riboflavin, and vitamin C, can leach into canning
or cooking water that may later be thrown away during preparation. Up to
half of the original content of water-soluble vitamins in a canned
product can be lost in this way. Rapid, high-temperature processes
generally conserve nutrient content best, as every 4.4° C (18° F) rise
in processing temperature yields approximately a ten-fold increase in
microbial destruction, with little additional nutrient loss.
Additives Food additives are chemicals that are added to food in small
amounts. Direct additives are added deliberately during processing to
make food look and taste better, maintain or improve nutritive value,
maintain freshness, and help in processing or preparation. Some
additives help preserve food by preventing or slowing chemical changes
and the growth of microorganisms in food. As many as 3000 substances are
approved by the Food and Drug Administration (FDA) for use as direct
additives. An additional 10,000 substances are present in foods as
indirect additives. These substances enter food incidentally during
handling or from processing equipment or packaging.
Food additives have been used for thousands of years. The salts and
other chemicals used in curing are additives, and before the advent of
canning and mechanical refrigeration, chemical additives were the only
means of preservation available. Additives were not limited to use as
preservatives, however. People in ancient Rome added certain chemicals
to wine and cooked vegetables to improve the color of these foods. Other
examples of additives that have been used since ancient times include
yeast and baking powder used as leavening in baked goods.
In the 20th century, advances in the knowledge of chemistry have greatly
expanded the number of additives that are used in foods. Such recent
additions to the ranks of food additives include artificial sweeteners,
such as aspartame and saccharin; fat replacements, such as Simplesse and
Olestra; and colors, such as FD&C yellow No. 5, which is used in
beverages, ice cream, cereals, and other foods.
The development of new chemical additives has also played an enormous
role in the growth of convenience foods. Additives that help ensure the
quality of convenience foods include anti-caking agents, such as calcium
silicate and magnesium stearate, to prevent lumps in dry mixes;
humectants, such as glycerol, propylene glycol, and sorbitol, to help
retain moisture in breads and cakes; emulsifiers, such as egg yolk,
lecithin, and monoglycerides, which bind oil and water to improve the
uniformity and smoothness of foods; and stabilizers and thickeners, such
as guar gum, carrageenan, and gelatin.
As the use of food additives has grown, so has public concern about the
type and amount of these additives and their potential to cause cancer
or other illnesses in human beings. Some studies have suggested that
saccharin, nitrites, and other additives may cause cancer, but these
results remain controversial. At the same time, some additives may
actually provide a health benefit. For example, the vitamins used to
fortify foods such as bread and milk are additives.
