Unpacking the World of Food Science

The annual meeting of the Institute of Food Technologists takes place in New Orleans’ Morial Convention Center, displaying a range of ingredients, from familiar ones like vanilla extract and dried fruit to lesser-known items like algae-based flour and inner pea fiber. All the showcased products aim to lower the production cost of foods.

The Dark Side of Food Technology

Food technology has enabled the creation of cheaper and convenient food products, but this has come at a cost. Starch thickeners and cellulose additives have been used to reduce production costs while maintaining the same taste and appearance of food products. Even fresh berries, an expensive ingredient used in prepared foods, have been replaced with “flavorings” and just 6% of the actual fruit. This has led to a growing concern over the nutritional value of processed foods and the quality of ingredients used in them. However, food technology can also serve a noble purpose, such as researching ways to reduce harmful bacteria and developing healthier options. Thus, it is important to balance the convenience offered by food technology with the nutritional value and quality of ingredients used, to ensure that we are not just consuming empty calories with no nutritional value.

Unveiling the Truth about Food

Dr. Harvey Wiley conducted an experiment in 1902 where he fed 12 men borax-tainted food to prove the necessity of evaluating commercially prepared foods for safety. He found that food sold as pure Vermont maple syrup was derived from cheap glucose, imported Italian olive oil was actually Alabama cottonseed oil, and bread was bulked with sawdust. He also uncovered that the food industry was using chemical preservatives on spoiled meat and deodorizing eggs with formaldehyde for baking. In the 20th century, the food industry’s growth aimed for innovation and creativity to increase sales and profit rather than creating healthier products. After Upton Sinclair’s book “The Jungle” exposed the unsafe meat-packing plants in Chicago, President Theodore Roosevelt introduced the Federal Meat Inspection Act and Pure Food and Drug Act of 1906. The need for food regulations was evident even during the early 1900s, and it continues to exist today.

The Cheesy Success Story

James Lewis Kraft, a cheese vendor in the early 1900s who wanted to develop a cheese that wouldn’t spoil, accidentally created a smooth, creamy glop of cheddar after absent-mindedly stirring heated cheese for 15 minutes. This cheese had no troublesome bacteria and became an overnight success. This success led Kraft’s sales to grow from $500,000 to $36 million in 1926. Later, the Kraft company substituted some of the actual cheese in its products with a cheaper milk-like substance that reduced production costs but didn’t meet government standards. The US Food and Drug Administration (FDA) gave Kraft three options: revert to its original formula, work on changing the processed-cheese standards, or call the product by a different name. Kraft chose to rename its product “Pasteurized Prepared Cheese Product.”

The Rise and Fall of Cereal Fortification

John Harvey Kellogg, the inventor of flaked cereal and founder of a health-oriented lifestyle, believed that coffee was harmful to the liver and sexual intercourse led to major diseases and erectile dysfunction. His discovery of flaked cereal, born out of an accidental mush in water, became a hit when the public started craving sweet cereal against Kellogg’s health principles, leading to the removal of healthy ingredients such as corn germ and bran, making cereal nutritionally deficient. Robert Choate’s study in 1970 revealed that two-thirds of cereals contained few beneficial ingredients and were referred to as “empty calories” that could cause malnutrition. Within two years, manufacturers resorted to fortify cereals with vitamins and minerals, advertising them as “new and improved”. Nevertheless, the idea of supplements and fortified cereals does little to prevent malnutrition, contradicting the idea of trying to eat healthily in the first place.

The Evolution of Vitamins

From the discovery of vitamins in the early 1900s to their mass addition in processed foods, the journey has been driven by profit rather than consumer health. Physician Christiaan Eijkman and biochemist Casimir Funk contributed to the discovery of vitamins. Eijkman observed beriberi in chickens that ate polished rice, but the condition went away when they switched to whole brown rice. Funk named the 13 vitamins and 14 minerals the body needs, which manufacturers started adding to processed foods in the 1930s. However, this trend was more about profits than improving the nutrition of consumers.
