Processed food, and three official wordings

As the food industry has developed, and as ways of eating have changed, the notes write, the making and the eating of processed foods have increased, and a careful consumer’s interest in the additives used along the way, and in their safety, has grown with it. A processed food, in their account, is a food made by working and altering raw materials from farms, from livestock, or from the sea, so that it tastes better, is easier to eat, and keeps longer. In that work some nutrients may be lost, and others may be added or taken out, so that the nutritional value of a processed product can differ from that of the same food in another form. Additives, they write, are used to raise quality, to improve keeping and palatability, and to increase a food’s nutrition or its essential value. They also note that, although additives are generally licensed as harmless to the body, most are chemically synthesized products, and that a long intake in large amounts may, in the writer’s view, build up and do harm; a license given after a scientific safety test may also, with later experiments, be found wanting.

In Korea, they write, Article 2 of the Food Sanitation Act defines a food additive, in processed food, as a substance used, in the making, processing, or preserving of a food, by adding, mixing, soaking, or other methods — including substances used to sterilize or disinfect utensils, containers, and packaging, which may reach a processed food indirectly. The Codex Alimentarius Commission, they add, defines an additive as a substance that is not itself eaten, or used as an ingredient of another processed food, and that, without regard to nutritional value, is added directly or indirectly for a technical or a sensory purpose in making, processing, cooking, treating, filling, packing, carrying, or keeping a processed food, with the result that the additive itself or its by-products become a constituent of the food or affect its nature. The wording, they write, covers every substance used in those steps. Neighboring Japan, they record, speaks of a substance used, in the making of a processed food, or for the purpose of processing or preserving it, by adding, mixing, soaking, or other methods.

A No Brand chip, and the additives on its list

As a worked example the notes pick one processed food: a snack they name as No Brand potato chips, sour cream and onion. On its list they find palm olein, with butylhydroxyanisole (an antioxidant); a sour-cream mix that includes a creamer — glucose syrup, palm olein, and a synthetic cream flavor — together with maltodextrin, chives, and onion oleoresin; emulsifiers, namely a glycerin fatty-acid ester and soy lecithin; and monosodium glutamate, or L-glutamate sodium, as a flavor enhancer. As they read the list, flavorings and acidity regulators are the main additions.

In snack cookies, they write, a flavoring is needed to stimulate the sense of taste, and an acidity regulator is added when flour is kneaded, in order to keep the pH at a proper level. Sodium bicarbonate and L-potassium bitartrate may also, in general, be added to snack cookies to increase their volume. An antioxidant is used, they write, because of the particular way such snacks spoil by oxidation. When an antioxidant such as BHT is combined with other substances, the writer claims, toxicity may rise, and it may be linked to a higher incidence of cancer, to birth defects, to delayed growth, and to unusual behavior. Those remarks are left as the writer’s own claims, not as later official findings.

Tar colors, and a closing that stays with the writer

The notes also pause on tar colors: synthetic coloring agents used to give a processed food its hue, synthesized, they write, from raw materials such as benzene, toluene, and naphthalene, taken from coal tar. They are used mainly in candies and drinks, in ice cream and chewing gum, and in snack cookies of this kind. An additive, they conclude, is a substance added to a processed food besides its original constituents, each with a purpose of its own, and, taken alone, a chemical additive that has no necessary relation to the consumer’s ordinary eating life.

The shop chrome on the notes sometimes bears another heading, about world politics and the economy; the unique sentences themselves are about additives, and the page follows those sentences. The same Korean report, at fuller length, is on CampusDown.
