  • Patent number: 6429293
    Abstract: The present invention provides inter alia, isolated “sculpin-type intracellular AFPs” from shorthorn sculpin and their corresponding nucleic acids. The sculpin-type intracellular AFPs are alanine-rich polypeptides that are synthesized in the peripheral tissues such as the skin and gills of fish. These skin-type AFPs are encoded by a distinct set of AFP genes that lack a signal peptide, which is indicative of their intracellular location. The polypeptides are used to make cells cold resistant and to improve the palatability of cold foods and liquids. Cold resistant eukaryotes and prokaryotes, including plants, animals and bacteria are made using the sculpin-type intracellular antifreeze polypeptides and nucleic acids. Moreover, the present invention provides methods for preserving cells, tissues and organs ex vivo using the AFPs described herein.

  • Patent number: 6375999
    Abstract: A sprout inhibitor for potatoes is introduced into a potato storage facility as a gas phase carried in an air stream. The liquid sprout inhibitor may be heated prior to injection into a flowing air stream or a large surface area of the liquid sprout inhibitor may be exposed to the air stream to induce evaporation of the inhibitor into a gaseous phase. Sprout inhibitors such as dimethylnaphthalene (DMN) and trimethylnaphthalene are especially suitable for introduction to potato storage sheds by thermal fogging or evaporative fogging. A method and composition to promote healing of freshly dug potatoes are further disclosed. Treatment of freshly dug potatoes with DMN either prior to or immediately after storage promotes rapid healing of cuts, abrasions and similar injuries to the potatoes. Stored potatoes first treated with DMN may be later advantageously treated with low levels of CIPC for effective sprout inhibition.

  • Patent number: 6027751
    Abstract: Disclosed is a method for preparing temperature-sensitive, shelf-stable, high-acid or acidified, tomato-based food products. From about 0.000125% to about 0.00125% nisin, and in preferred embodiments from about 0.00025% to about 0.0005% nisin, based on the weight of the food product, is first mixed with the tomato-base. Other ingredients, such as pieces of fresh tomatoes, onions, bell peppers and the like are then combined with the nisin-containing mixture. The combination is then heat-treated at a temperature less than about 180.degree. F.

  • Patent number: 6004601
    Abstract: A method for green color retention and texture improvement in vegetables by blanching raw or IQF green vegetables in an aqueous zinc blanch solution for three minutes or less, wherein the aqueous blanch solution has a zinc ion concentration of at least about 500 ppm. The vegetables may then be containerized and sterilized, frozen or dried. The zinc-blanched and frozen or dried vegetables may be sold as ingredients to the food industry, or they may be containerized and sterilized in brine, or in complex products, such as soups, sauces, or any other thermally processed products.

  • Patent number: 6001411
    Abstract: A method for preparing frozen par-fried potato strips comprising about 32% to about 52% moisture which remain fresh tasting after storage at about 0.degree. F. (-17.8.degree. C.). The method comprises peeling, trimming and cutting raw potatoes into strips, blanching, and reducing the moisture content of the potato strips to not less than about 54% followed by, par-frying the potato strips in oil for a time sufficient to reduce the moisture of the potato strips to a final moisture content of from about 32% to about 52%. Thereafter, the par-fried potato strips are frozen. The frozen par-fried potato strips have reduced levels of 2,5-dimethyl pyrazine and relatively high levels of 2,4-decandienal. When cooked, the finished French fries have improved flavor over conventional oven baked fries.
