time required for the preparation of chocolate that contains low-calorie cocoa butter substitutes. The chocolate prepared using this process has acceptable gloss and has sensory properties on a par with those of chocolate prepared using traditional processes. The process comprises the following steps: formation of an untempered chocolate composition that contains a reducedcalorie fat; heating the composition to 37.8-65.5”C to form a melt; filling of bar moulds with the untempered chocolate composition; removal of any air bubbles that are present in the composition; rapid cooling of the moulds to a temperature that is low enough to achieve a composition-mould interface temperature of <22.2”C; and holding the moulds at this temperature for O-15 min.

Mansukhani, G., Kiefer, 1.1. and d’ottavio, N. (Warner-Lambert Co., Morris Plalns, NJ, USA) United States Patent US 5 601 858 A non-stick chewing gum base composition, which is free from fats, waxes and elastomer solvent resins, is described, together with the chewing gum made from the gum base composition. The resulting chewing gum is easily removed from a variety of surfaces.

Engineering/packaging High-pressure

preservation/storage

Hirsch, G.P. (Hirsch, Decatur, GA 30033-3912, USA) United States Patent US 5 593 714 A method for the pressure preservation of foods and food ingredients. Because no heat is used, the foods retain much of their firmness and texture. The products are sterilized and preserved by the application of a pressure of 25OkPa (25 000 psi) for 5 days. Specifically, seafoods require maintenance of this pressure for the duration of storage. In the case of fruit and vegetables, ripening is stopped by the pressure treatment; packaged products can be stored without refrigeration for 26 months.

hot-food

vending

P (Smith, Los Angeles, CA 90046, States Patent US 5 59s 947

USA)

An automatic vending machine for dispensing hot foods. The machine has a hopper for holding individual frozen or refrigerated food portions and for maintaining the foods in the refrigerated or frozen condition. Insertion into the machine of a dollar bill is verified by an electro-optical mechanism that signals the control and monitor circuitry to initiate food preparation; the microwave oven below the hopper opens and rotates into a food-receiving position. A dispenser then introduces an individual portion of food into the oven by gravity. The oven rotates into a horizontal cooking position and its door is closed; the food portion is heated by microwave energy for a predetermined length of time. Upon completion of heating, the oven door is opened and the oven tilted downwards; the heated food portion is dispensed by gravity through an opening port in the machine. Circuitry is provided for monitoring the progress of the preparation and delivery cycle and for refunding the purchase price in the event of the machine being empty or when a malfunction occurs. Additionally, the machine may be adapted for monitoring and recording machine status and for notifying a remote location by telephone of problems or maintenance needs.

Mayerthaier, R. (Mayerthaler, Germany) German Federal 196 11 399 Cl lin German1

Moosburg, Patent DE

A method for the automatic control of the fermentation of beer is based on the measurement of the energy requirement for cooling the fermentation tank as an index of fermentation activity in the tank. Fermentation temperature is automatically increased or decreased to correct any deviation from the planned fermentation pattern. The ideal time for temperature changes, the removal of yeast and re-circulation pumping of the beer can be determined. This process optimizes the efficiency of tank use, improves beer quality, and permits long-

term planning; labour considerably reduced those of manual process

Low-fat foods Ca-enriched absorption

fat

Cernsh, T., Hlgglns, C. and Kresl, K. (Cerrish, Kennett Square, PA 19348, USA) United States Patent US 5 601 861 A method and the composition for preparing battered and breaded foods that do not absorb oil during deep frying. The Ca-pectin coating prevents the absorption and adsorption of frying oil, and increases the moisture content, crispness and stability of the product. The breading composition is enrlched with Ca; this is accomplished bv dry blending, spray drying or agglomerating, by baking the Ca source onto the bread crumb, or by any combination of these methods. The battered and breaded food is then treated with a solution of Ca-reactive pectin. Al-ternatively, the food may first be treated with the Ca-reactive pectin and then the Ca source, depending on the circumstances of use.
