Fabrication of Food Bars Based on Compression and Molding Matrices

摘要

Dried foods, some plasticized to prevent fragmentation, were compressed with appropriate binders into bars of approximately equal size, density and caloric content. Bars representing the following food items were designed, formulated, fabricated and evaluated for physical, chemical and sensory characteristics after storage for 3 months at 38C: (1) Citrus Fruit Drink (2) Hot Chocolate Beverage (3) Cream of Mushroom Soup (4) German Potato Salad (5) Cole Slaw (6) Pineapple-Cottage Cheese Salad (7) Welsh Rarebit (8) Crab Meat Cocktail (9) Chocolate Pudding (10) Pineapple Fruit Pudding. Complete information on all formulations and processing is supplied. In accordance with design requirements bars were rated by a taste panel as acceptable for consumption from the dry-compressed state and for consumption after rehydration for 20 minutes in water at 70C. (25C for items consumed at room temperature.) Bars were evaluated for cohesiveness, dimensional stability under pressure, ease of shear by the incisors and subsequent mastication. Observations on free fatty acids, peroxide value and browning (fluorescence units) are recorded for each bar at the time of fabrication and after the referenced storage. (Author)
