Abstract:In this work, evaporated skimmed milk, pumpkin powder, oat flour, walnut flower powder and xylitol as materials, a breakfast powder of full taste and nutrition was developed. First, sensory quality as an evaluation criterion, through single factor tests, the amounts of different materials added were determined. On this basis, an orthogonal experiment of four factors and three levels was done to significantly study the impacts of materials on the taste, texture, flavor, color and tissue morphology of breakfast powder. The best formula for breakfast powder is pumpkin powder 3g, skimmed milk powder 15g, oat flour 6g, walnut powder 0.5g and xylitol 1g.

南瓜系葫蘆科南瓜属一年生蔓性草本植物[1],果实含有丰富的碳水化合物、蛋白质、膳食纤维、维生素、胡萝卜素、氨基酸、果胶及K、Ga、Mg等矿物元素,脂肪含量却十分低[2],具有降血糖、降血压、扩张血管、预防癌症、促生长发育、促消化、美容减肥等特殊功效[3]。燕麦(又名莜麦)为禾科植物,是一种低糖高营养食品,可以预防和治疗肥胖症、高血压、糖尿病、心血管疾病等“现代文明病”[4]。核桃花又称核桃纽、长寿菜、龙须菜,其含有丰富的磷脂,有益于增强人体细胞活力,促进人体造血功能,能有效降低血脂、胆固醇,预防动脉硬化[5]。本试验以脱脂奶粉为主要原料,南瓜粉、燕麦粉、核桃纽粉及木糖醇为辅料,研究开发一种营养丰富,口感适宜,特别是适合“三高”人群食用的方便早餐粉。
