This means that these foods can be considered high risk and must be handled properly. [28] There are three varieties: chemostats, which hold nutrient levels constant; turbidostats, which keep cell mass constant; and plug flow reactors in which the culture medium flows steadily through a tube while the cells are recycled from the outlet to the inlet. A nut is a type of fruit (and not a seed), and a seed is a ripened ovule.. The reaction is catalyzed by the enzymes pyruvate decarboxylase and alcohol dehydrogenase.[13]. [citation needed], Although yeast carries out the fermentation in the production of ethanol in beers, wines, and other alcoholic drinks, this is not the only possible agent: bacteria carry out the fermentation in the production of xanthan gum. These raw materials can have a high amount of physical contaminants such as rodent hair, soil, insect parts, dust, unwanted debris, pieces of metal, and glass.

The consequence of these events is that pathogens from raw food ingredients can be transferred to cooked food and contaminate them. Despite the efforts of food safety agencies to minimize the occurrences of foodborne illnesses,mistakesand the lack of commitment to food safety contribute to the dominant existence of food safety concerns.

During preparation, cross contamination is most likely to occur when not careful. [13][14] It is used to make bread dough rise: the carbon dioxide forms bubbles, expanding the dough into a foam. Reasons to go further and convert lactic acid into something else include: Hydrogen gas is produced in many types of fermentation as a way to regenerate NAD+ from NADH.

Different types of pests can carry several disease-causing microorganisms. [citation needed], In ethanol fermentation, one glucose molecule is converted into two ethanol molecules and two carbon dioxide molecules. These harmful microorganisms are then transferred by skipping food hygiene practicessuch as handwashing in between touching raw food, equipment, cooked products, and from a different food worker.
