Roasted groundnut seeds, amaranth and dates pulp formed the center filling which was coated with sugar, breadings, desiccated coconut and roasted Bengalgram flour (BGF) to get 4 coated snacks. Physicochemical characteristics, microbiological profile, sorption behaviour and sensory quality of 4 coated snacks were determined. Centre filling to coating ratio of the products were in the range of 3:2-7:1, the product having BGF coating had the thinnest coating. Center filling had soft texture and the moisture content was 10.2-16.2% coating had lower moisture content (4.4-8.6%) except for Bengal gram coating, which had 11.1% moisture. Sugar coated snack has lowest fat (11.6%) and protein (7.2%) contents. Desiccated coconut coated snack has highest fat (25.4%) and Bengal gram flour coated snack had highest protein content (15.4%). Sorption studies showed that the coated snack had critical moisture content of 11.2-13.5%. The products were moisture sensitive and hence require packaging in films having higher moisture barrier property. In freshly prepared snacks coliforms, yeast and mold were absent. Mesophillic aerobes count did not show significant change during 90 days of storage at 27 °C and 37 °C. Sensory analysis showed that products had a unique texture due to combined effect of fairly hard coating and soft center. Flavour and overall quality of all the products were rated as very good.
烤花生仁、苋菜和枣泥构成了中心馅料,然后将馅料裹上糖、面糊、椰丝和烤孟加拉豆粉(BGF),制成 4 种涂层小吃。对这 4 种涂层小吃的理化特性、微生物特性、吸附特性和感官质量进行了测定。产品的馅料与涂层的比例在 3:2-7:1 之间,BGF 涂层的产品涂层最薄。中心馅料质地柔软,水分含量为 10.2-16.2%,涂层水分含量较低(4.4-8.6%),除了孟加拉豆涂层的水分含量为 11.1%。糖涂层小吃的脂肪(11.6%)和蛋白质(7.2%)含量最低。椰丝涂层小吃的脂肪(25.4%)含量最高,而孟加拉豆粉涂层小吃的蛋白质(15.4%)含量最高。吸附研究表明,涂层小吃的临界水分含量为 11.2-13.5%。这些产品对水分敏感,因此需要使用具有更高水分阻隔性能的薄膜进行包装。在新制备的小吃中,大肠菌群、酵母和霉菌均不存在。在 27°C 和 37°C 下储存 90 天时,需氧嗜温菌的数量没有明显变化。感官分析表明,由于相当硬的涂层和柔软的中心的综合作用,产品具有独特的质地。所有产品的口感和整体质量都被评为非常好。
