United States Patent US 5 453 420

Garlic essence is produced by extracting garlic with ethanol, and is deodorized with phytic acid. The essence has high antibacterial activity when sprayed onto food, and can thus be used as a food preservative. The essence is used alone or in combination with e-polylysine at a concentration of l-256 kg/ml.

Natural antioxidant enzymes from melons Cinoux, J.P., Dreyer, A., Roth, P., Baccou, J.C. and Lacan, D. (Bio-Obtenition SC, France) French Patent Application FR 2 716 884 Al [in French]

Soluble protein extracts of melons (Cucumis me/o) with superoxide dismutase activity >30 units/mg protein and, preferably, catalase activity >45 units/mg protein can be used as antioxidants in foods, cosmetics and pharmaceutical preparations. Preferably, these protein extracts should be prepared from melon cultivars obtained by genetic crossing and with a shelf life of 14days, especially the line 95LS444 or a hybrid derived from this line.

content of the cheese block as a function of temperature may be studied by slicing it into sections. The apparatus comprises an insulated chamber with heat-exchange surfaces disposed over and closing its two openings, which are separated by the length of the chamber. The temperatures of the two heatexchange surfaces are different and a temperature gradient is established in a block of cheese within the chamber.

Beverages Lysozyme for improved wine quality control Dell’Acqua, E. (LHC Lysozyme Holding Co., Road Town, Tortola, VI, USA i Dell’Acqua, A.) PCT International Patent Application WO 95/20644

Quick-cook precooked barley Messick, D.L. (Kraft Foods Inc., Northfield, USA) United States Patent US 5 464 647

IL,

Method of manufacture for a quickcooking barley and a method for cooking the product. The texture of the cooked barley is 75-90 lb/force when measured by shear press value. The moisture content of pearled barley is raised to 55-60% by cooking; the barley is then subjected to ambient pressure in an

Dual-flavoured layered chewing gum Kabse, K. and Hager, WJ. (Warner-Lambert Co., Morris Plains, NJ, USA) United States Patent US 5 437 879

A multi-layered chewing gum that provides an initial temporary flavour, followed by a second sustained flavour. The initially soft texture of the layered chewing gum is converted to that of standard chewing gum after several minutes of chewing. Chewing gum is used to sandwich a layer, or layers, of a gel-cream confection; the initial flavour is provided by hydrophilic components of the gel-cream, and the subsequent sustained flavour by the chewing gum composition.

atmosphere saturated with steam, and sprayed with hot water to achieve a drained moisture content of 70-80%. The barley is then drained and dried to a moisture content of 12% or less. The barley product is cooked by hydration in an equal volume of boiling water for 5-15 min, followed by 5 min standing in the cooking liquor.

Flavour enhancement in cultured dairy products Mehnert, D.W. (Kraft Foods Inc., Northfield, USA) United States Patent US 5 462 755

IL,

Methods, and compositions, for flavour enhancement and development in fermented dairy products, particularly reduced-fat fermented dairy products, which identify and select fat fractions from sources such as milk (butter) fat for use as flavour precursors. The selected fractions are added to the product during the manufacturing process, where they are available for flavour development by means that are characteristic of the product. The selected fractions are preferably enriched in fatty acids and have low melting points. The flavour precursors are usually added in combination
