Vegetable fermentation production

The bacterial culture converts a portion of the supplied nutrient into vegetative cells, spores, crystalline protein toxin, soluble toxins, exoenzymes, and metabolic excretion products by the time of complete sporulation of the population. Although synchronous growth is not necessary, nearly simultaneous sporulation of the entire population is desired in order to obtain a uniform product. Depending on the manner of recovery of active material for the product, it will contain the insolubles including bacterial spores, crystals, cellular debris, and residual medium ingredients plus any soluble materials which may be carried with the fluid constituents. Diluents, vehicles, stickers, and chemical protectants, as the individual formulation procedure may dictate, are then added to the harvested fermentation products. The materials are used experimentally and commercially as dusts, wettable powders, and sprayable liquid formulations. Thus, a... 

There are four different drug products under Part II chemical active substance(s), radiopharmaceutical products, biological medicinal products, and vegetable medicinal products. For example, the GMP production report for biological medicinal products includes description of the genes used, strain of cell line, cell bank system, fermentation and harvesting, purification, characterization, analytical method development, process validation, impurities, and batch analysis (GMP production of biopharmaceuticals is described in Chapter 10). A DMF (Exhibit 8.8) is submitted. 

In general, there is a low risk of high amounts of BAs in vegetables and root crops, where BAs are produced as a result of lactic acid fermentation (81,82). Furthermore, the His contents reported in sauerkraut (83,84), cucumbers (85), and green table olives (86) are far below the level of 100 mg per 100 g that has been associated with outbreaks of food poisoning. Nevertheless, a safe evaluation of the products of natural lactic fermentation should take into account other amines, because Tyr, Put, and Cad can also be produced during sauerkraut fermentation (87). Moreover, certain strains of lactobacilli and cocci have been associated with the presence of these compounds in fermented products (82) and synthetic broth (88). 

The term artificial flavor or artificial flavoring means any substance, the function of which is to impart flavor, which is not derived from a spice, fruit or fruit juice, vegetable or vegetable juice,. .., or fermentation products thereof.. .. The term... 

LAB are industrially used as starter cultures and as probiotics to perform controlled fermentations for the production of dairy, meat, vegetable, and bakery-fermented foods. L7U1 with specific characteristics have been isolated from a variety of traditional fermented products or from diverse raw materials used as starter cultures to obtain controlled and uniform fermented foods [14-16]. 

The final fermented product (pH < 4.1) may either be distributed fresh, packaged or unpackaged, or pasteurized in pouches, cans or jars. In the latter case, the fermented vegetables are first blanched and then filled into the container, poured and after closing subjected to a gentle pasteurization. For victuals that easily soften, the original fermentation liquid should be replaced by a brine containing certain amount of sodium chloride and lactic acid in order to top the containers. 

Other food additives may be applied in vegetable fermentations, but will depend on the particular product, while regulatory restrictions may be posed in numerous countries. Ascorbic acid is frequently added to sauerkraut, mainly with the purpose of preventing gray or brownish discolourations of fresh or canned products. In some countries citric acid or sulphur dioxide is permitted for preventing discolourations.
