A ready-to-freeze beverage is provided comprising the stigmasterol-rich composition and water, with optional additives. A frozen beverage is prepared from the ready-to-freeze beverage as a pourable slush. There are further provided processes to prepare the ready-to-freeze beverage and the frozen slush beverage.
摘要:
The typically employed step of separately hydrating gelatin in warm water for the preparation of aerated, gelatin-containing confections such as marshmallow is replaced by hydrating a dry blend of sucrose and gelatin in cold water prior to heating. The marshmallow products produced by this process are made more efficiently and have good string. The gelatin processed in this manner undergoes less cis isomerization than occurs during conventional processing. The invention improves processing for the production of marshmallow pieces, marshmallow fillers, e.g., for cookies and candies, dehydrated marshmallow bits and spoonable marshmallow toppings.
摘要:
Baked, wheat-based, chip-like snacks having a plurality of surface bubbles comprising air pockets extending both above and below the substantially unleavened, adjacent portions of the snack are obtained with a pregelatinized waxy starch, pregelatinized potato starch, and optional modified potato starch. The pregelatinized potato starch produces a crisp, crunchy texture in the baked snack. The pregelatinized waxy starch is at least substantially uniformly hydrated prior to baking for producing bubbles during baking and for retaining the bubbles. The pregelatinized potato starch is at least substantially uniformly hydrated prior to baking for controlling bubbling caused by the pregelatinized waxy starch and for controlling texture of the bubbled and unbubbled portions of the snack chips. Use of the gluten-containing wheat flour and bubble-forming amounts of the pregelatinized waxy starch provides for the production of a cohesive, non-sticky, extensible, continuously machinable dough. A modified potato starch which is activated during baking may be used to enhance surface bubbling and crispiness of the bubbled portions and unbubbled portions. The pregelatinized waxy maize starch may be used in an amount of from about 3% by weight to about 20% by weight, and the pregelatinized potato starch may be used in an amount of from about 1.5% by weight to about 20% by weight, each based upon the weight of the wheat flour. The weight ratio of the amount of the pregelatinized waxy starch to the total amount of the potato starches may be from about 0.45:1 to about 1:1. Non-fermented and fermented reduced fat, low-fat, and no-fat baked products, as well as full-fatted non-fermented and fermented baked products, may be produced with a bubbled surface, and a crispy, crunchy, non-mealy, chip-like texture, but with a wheat cracker flavor.
摘要:
Low moisture content comestibles having reduced water regain or increased tolerance to moisture are produced by enzymatically treating a farinaceous material with an enzyme composition comprising pentosanase or beta-glucanase, or mixtures thereof to reduce its net-work forming swellable water-soluble hemicellulose content. The hydrolysis of the water-soluble pentosans, beta-glucans or mixtures thereof is conducted so that a substantial portion of the hydrolysis product has a linear or backbone degree of polymerization of less than about 100, more suitably less than about 75, preferably less than about 50, most preferably less than 17. In addition, the hydrolysis is conducted so as to minimize the production of mono and/or di-saccharides. The low moisture content comestible products include low moisture content baked good such as cookies, crackers, and biscuits, farinaceous pet snacks, plant protein extracts, hot cereals, ready-to-eat cereals, low calorie flours and low calorie flour fractions. The enzyme compositions which are used are preferably substantially completely free of proteases and amylases so as to avoid reducing the functionality of proteins and starch, respectively. The comestible products have a moisture content of less than about 20 percent by weight. Hemicellulose hydrolyzates may also be produced for incorporation into comestibles.
摘要:
A stable, food-compatible liposome is prepared by dissolving a lipophilic material in a phospholipid followed by the addition of water or an aqueous solution and mixing by sonicating to produce a liposome having the lipophilic material encapsulated in the lipid bilayer. The preferred lipophilic materials include any readily oxidizable lipid and in particular the omega-3 fatty acid containing fish oils. Other lipophilic materials which can be encapsulated in the lipidic bilayer include flavorants, acidulants, preservatives and antioxidants. The resulting liposomes provide a stabilizing vehicle for the lipophilic materials to reduce the occurrence of oxidation and rancidity. Liposomes prepared according to the disclosed method exhibit none of the unpleasant odor and flavor characteristics normally associated with oxidized or rancid oils. The liposomes provide an extended shelf life of the unstable oils and can be added directly to the food product as a dispersion during the manufacturing stage or dried to a free flowing powder for later use.

摘要:
A hard, clear, glassy, smooth polymer with a dry surface having a dye precursor therein which forms a permanent color at those areas of the solid polymer that have been irradiated with ultra-violet or ionizing radiation is formed by combining vinyl and/or acrylic monomers, a triphenylmethane cyanide dye precursor and a chemical initiator that is compatible with the dye cyanide and polymerizing in the presence of a slight excess of hydrogen ions in an inert atmosphere.
摘要:
A flexible, strip-shaped food product is made by comminuting substantially frozen meat and heating the comminuted meat to at least partially denature the meat proteins and cooling the cooked meat. About 4% by weight to about 45% by weight of wheat flour is admixed with the cooked meat, along with other ingredients, to form a dough. Use of the wheat flour unexpectedly increases tensile strength of the dough and products baked from the dough, and maintains flexibility of the strip-shaped food products over an extended period of time. Cooking of the meat in the presence of salt unexpectedly increases water activity of the pieces, resulting in a product that has a skin and a moist middle, while maintaining tensile strength. The dough is rotary-molded into strip-shaped pieces. The rotary mold may have angled die cups. The strip-shaped dough pieces are then baked and dried.
摘要:
A heat- or microwave-activated browning composition is prepared for coating a food product to produce surface browning on exposure to heat or microwave energy. A method of browning a food product includes the steps of coating a food product with a microwaveable browning composition and subjecting the coated product to heat or microwave energy. The microwaveable browning composition includes at least one liposome-encapsulated Maillard browning reagent. A basic amino acid is encapsulated in the aqueous interior of the liposome. A reducing sugar is dissolved in the external aqueous phase of the liposome. The external aqueous phase may also contain a film-forming material. The Maillard browning reaction is triggered by heat or microwave energy. This heat or microwave energy causes the liposomes to rupture, releasing amino acid to react with reducing sugar, producing Maillard browning products. If a basic amino acid is used, the reaction is further catalyzed by a rise in pH of the external aqueous phase upon release of the amino acid from the liposome. Furthermore, phospholipids (from which the liposome vesicles are made) can enhance the extent and rate of Maillard browning product formation.
