Zusammenfassende Schlussfolgerungen,Foods are normally contaminated with microbes (or microorganisms) that are so small that a microscope is required to see them. Microbes include bacteria, yeasts, molds, virus, algae, and protozoans. However, the organisms that normally contaminate and spoil food are the bacteria, with yeasts and molds of secondary importance.作者: intricacy 時間: 2025-3-26 06:03 作者: 冷峻 時間: 2025-3-26 12:13

It is believed that many foods, especially grains and fruits of high sugar content, were preserved by primitive peoples by allowing the foods to dry in the sun. Spices and fish, cut into thin strips, were also preserved in this manner.作者: 送秋波 時間: 2025-3-26 15:25

Chemical ReactionsFoods sometimes deteriorate because of chemical changes not associated with microbial growth or enzyme-induced chemical reactions. Actually, certain components in foods are subject to reactions that involve either a combination with naturally occurring elements (such as oxygen) or with compounds present in the foods themselves.作者: 外形 時間: 2025-3-27 07:42 作者: Muscularis 時間: 2025-3-27 10:46

Zur Methode und zum Erkenntnisinteresse,actors. If a food doesn’t look, feel, and taste good, most consumers in countries where food is abundant will not purchase it a second time, even if the price is right, and the food is wholesome and nutritious.
