Introduction

Food science is defined as the discipline of applying chemistry, engineering, microbiology, medicine, and molecular biology tocreate, prepare, and process foods.

Food scientists use science and engineering to produce, process, evaluate, package, and distribute foods that are nutritious, palatable, and safe.

Methods that food scientists employ include basic research, product development, quality control, processing, packaging, labeling, technical sales, and market research.

The U. S. is faced with a decreasing population of farmers and ranchers who produce food for an increasing world population.

Technological advances in genetics, soil science, food processing and purification, and marketing have helped produce food for the world.

The Role of Government in the Food Industry

The food business is a complex system of marketers, buyers, and transporters that orchestrate how food gets from the processor to the grocery store shelf.

Government agencies regulate and inspect all phases of food production to ensure that consumers have food that is both wholesome and safe.

The Food and Drug Administration (FDA) and the United States Department of Agriculture (USDA) are two government agencies that regulate the food industry.

Food Labeling

The U.S. Food and Drug Administration requires that certain labeling be placed on food products that are packaged for consumption.

Food labels are required to include information about nutritional facts (Recommended Daily Allowances) of the product based on serving sizes.

Labels also tell the consumer about the natural and additive substances in the foods.

Food Processing From Grower to Consumer

Farmers and ranchers grow the food we eat, including fruits, vegetables, cereal grains, meat, and other foods.

Food must then be processed, cooked, packaged, and transported.

Some of the allied food industries include:

• Steel companies that make cans;

• Chemical companies that produce food preservatives; and

• Plastic companies that develop food packages.

Food processing is used to reduce spoilage.

Foods are cleaned, canned, dehydrated, frozen, refrigerated, and packaged to eliminate bacterial contamination, which can cause food poisoning and other health risks.

Types of food processing includes: cold processing; dehydration; irradiation; fermentation; milling and cereal processing; hydrogenation; and formulated prepared.

Manufacturers purchase food from growers and prepare or process the food to be stored and sold at wholesale operations and grocery stores.

Retail stores sell food bought either from manufacturers or wholesalers and then sell this food to consumers.

Managers, marketers, and distribution specialists must keep track of this complex trade and check for damaged goods or products that may be spoiled.

The consumer is the last stop on the check for safe food. Consumers should check expiration dates and make sure that the foods that they purchase and eat follow governmental codes for safety.

Food Biotechnology: Benefits and Potential

RisksFood producers use technology to solve problems such as pests, disease, fungal infections, and poor soil quality so that they can provide a sufficient amount of raw foods for an increasing world population.

In the early 1900’s, scientists introduced chemicals that could be used on crops to increase yields and maximize the growth of raw food.

However, concern over the way that increasing amounts of chemicals used on crops may be impacting our bodies and the environment in potentially harmful ways has led to the development of new methods of pest control.

Biologically altered agronomic crops, integrated pest management techniques, and organic farming methods have been offered as alternative farming methods.

Genetically modified organisms (GMOs), such as Bt Corn, have provided alternatives to chemicals.

However, concern from the public and scientific community over genetically engineered plants and animals has this area of biotechnology under hard scrutiny.

More research needs to be conducted to assure the safety of biologically altered foods for human consumption.
