    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.

    摘要: A cookie product is prepared having a liposome-encapsulated component dispersed therein and leavened to a crumb-like structure. The liposomes substantially retain their structural integrity during the processing, mixing, and post extrusion baking and thus remain intact in the finished cookie. The liposomes may encapsulate flavorings, fragrances, preservatives, anti-staling agents, and other labile food additives. The liposomes may provide a sustained release of the encapsulant to the cookie during storage and prior to consumption. The encapsulant may be released when the cookie is baked or eaten by the consumer. The cookies are prepared by feeding the cookie ingredients to a blending zone of a cooker-extruder and heated to form a heat treated mass. A liposome-encapsulated component is added to the cooled heat treated mass and mixed at low pressure and temperature to prevent rupture of the liposomes. An optional source of water may also be admixed to form a dough-like mixture. The dough-like mixture is then extruded into shaped cookie pieces, and leavened by heating in an oven. The heat treating of the dough-like mixture in the cooker-extruder reduces the post extrusion baking time such that liposomes prepared from phospholipids having a high phase transition temperature substantially retain their structure integrity in the leavened cookie.
