  • Patent number: 5868997
    Abstract: A method for sterilizing process fermentation vessels with a concentrated alcohol and water mixture integrated in a fuel alcohol or other alcohol production facility. Hot, concentrated alcohol is drawn from a distillation or other purification stage and sprayed into the empty fermentation vessels. This sterilizing alcohol/water mixture should be of a sufficient concentration, preferably higher than 12% alcohol by volume, to be toxic to undesirable microorganisms. Following sterilization, this sterilizing alcohol/water mixture can be recovered back into the same distillation or other purification stage from which it was withdrawn. The process of this invention has its best application in, but is not limited to, batch fermentation processes, wherein the fermentation vessels must be emptied, cleaned, and sterilized following completion of each batch fermentation process.

The method comprises adding nisin to the wine at a concentration lethal to nisin-sensitive LAB, adding to the wine an inoculum of nisin-resistant LAB mutants capable in the presence of nisin of converting malic acid to lactic acid, and maintaining the inoculated wine under conditions in which the MLF can occur. Afterward, nisin can be removed from the wine by contacting the wine with a nisin-removing substance, such as bentonite. The nisin can be added either before or simultaneously with addition of the nisin-resistant LAB, at any time during winemaking, including primary yeast fermentation.

The terpene is added in an amount which is effective to obtain viricidal activity but ineffective to cause toxic effects on the microorganisms. The terpene is one obtainable from aromatic plants by steam distillation. Terpenes or mixtures of terpenes which have proved suitable are those obtained from black pepper oil, cinnamon flower oil, cardamon oil, linallyl acetate, cinnamic aldehyde, safrol, carvon and cis/ trans citral, used individually or mixed together. They may added dissolved in a carrier such as 1,2-propanediol.

  • Patent number: 4407828
    Abstract: A method is described for producing fermented foods by generating lactic acid in the food using a culture of a lactobacillus similar to Lactobacillus casei subspecies alactosus NRRL-B-12,344 and a stimulatory food grade metal salt, wherein the culture has unique rapid low temperature fermentation characteristics and wherein lactose, glycogen, and starch are not fermented by the culture. The preferred Lactobacillus casei subspecies alactosus is NRRL-B-12,344 or strains having low temperature food fermentation characteristics in common with this strain. In order to provide rapid fermentation, the stimulatory, food grade metal salt, usually a manganese salt, is provided in the food or the culture which is added to the food with the selected lactobacillus to accelerate fermentation. The cultures are particularly suited for the controlled fermentation of carbohydrates, naturally present in or added to the food to provide a selected final pH.

  • Patent number: 4250267
    Abstract: A process for immobilizing a biological material which can be a protein, a coenzyme having at least one primary or secondary amino group per molecule, an admixture of said coenzyme and an enzyme which is mediated by said coenzyme, or an antibiotic having at least one primary or secondary amino group per molecule, wherein the biological material is contacted with an excess of an isocyanate-capped liquid polyurethane prepolymer in the absence of water, and the resulting mixture is cured by contacting it with a curing agent to cure the prepolymer and to immobilize the biological material. The resulting mixture can be cured under foam-forming conditions or under nonfoam-forming conditions. The resulting mixture can be formed into a predetermined shape before or during curing or coated onto a surface before or during curing.

  • Patent number: 4239783
    Abstract: The mixing time required to develop yeast leavened dough compositions is reduced by incorporating in the dough composition prior to mixing from 0.001 to 0.015 parts by weight of sorbic acid or a sodium, potassium or calcium salt of sorbic acid, for each 100 parts by weight of flour. The reduced mixing time is achieved without adverse effect on the quality of the baked product and without significant reduction in tolerance to overmixing by the dough composition.
