  • Patent number: 4997663
    Abstract: Parboil or raw "skinless" sausages are prepared using a reusable tubular casing formed from a lipophilic, relatively nonpolar material in a process wherein the casing is filled with uncoagulated sausage material containing protein and fat (lipids) and initially heated to a relatively high temperature for a short period of time (e.g. about 175.degree.-250.degree. C. for 2-3 minutes) to preferentially coagulate only the protein material immediately adjacent the casing to form a relatively thin (e.g. less than about 1 mm) cohesive, "skin-like" layer. The sausage is then removed, such as by ejection, for further processing, such as smoking, drying, reddening and final coagulation with the "skin-like" layer providing sufficient support for the subsequent processing of the substantially uncoagulated ejected sausage material, and the casing is simply rinsed and refilled.

    Abstract: Low acid heat-sensitive foodstuffs, such as low acid heat-sensitive vegetables and cereal grain products, are thermally processed in the presence of a mixture of an acid and its lactones, preferably an aldonic acid with its lactones, the acid of which makes possible a considerably reduced commercial sterilizing parameter whereby more of the flavor, color, or texture of the foodstuff is retained, and is closer to that of the freshly harvested home-cooked product, compared to the foodstuff processed at a more severe parameter when the acid is not employed. The type and level of the acid employed and its presence with its lactones results in a thermally processed foodstuff which does not have an objectionable acid taste. The preferred mixture is gluconic acid with its lactones, glucono-delta lactone and glucono-gamma lactone, provided to the foodstuff by combining it with a precursor of gluconic acid, preferably glucono-delta lactone.

  • Patent number: 4764385
    Abstract: A process for preserving fresh fruit or vegetable products comprises the steps of; heating the fruit or vegetable product rapidly and uniformly to a temperature sufficient to destroy the natural enzymes which are present in the product without cooking the product, and immediately thereafter, cooling said product rapidly to a cold condition to remove the enzyme destroying heat before any significant cooking of the product can occur and to cool the product to a temperature which will inhibit deterioration of the freshness thereof. Shortly thereafter, while the product remains in said cold condition, it is placed in a sealed gas-type package.

  • Patent number: 4741911
    Abstract: Low acid heat-sensitive foodstuffs, such as low acid heat-sensitive vegetables and cereal grain products, are thermally processed in the presence of a mixture of an acid and its lactones, preferably an aldonic acid with its lactones, the acid of which makes possible a considerably reduced commercial sterilizing parameter whereby more of the flavor, color, or texture of the foodstuff is retained, and is closer to that of the freshly harvested home-cooked product, compared to the foodstuff processed at a more severe parameter when the acid is not employed. The type and level of the acid employed and its presence with its lactones results in a thermally processed foodstuff which does not have an objectionable acid taste. The preferred mixture is gluconic acid with its lactones, glucono-delta lactone and glucono-gamma lactone, provided to the foodstuff by combining it with a precursor of gluconic acid, preferably glucono-delta lactone.

  • Patent number: 4734291
    Abstract: An al dente pasta product having storage stability is produced by partially cooking freshly extruded pasta with steam or boiling water. Measured amounts of the partially cooked pasta are sealed in a container with measured amounts of water sufficient to complete hydration to 65% to 75% moisture and measured amounts of a food grade acid sufficient to reduce the pH to 4.6 or less. The sealed containers may be commercially sterilized under moderate thermal processing conditions. In a specific embodiment, the containers contain pasta in a carbon dioxide atmosphere.
