Conduct single factor tests on the composition of various raw materials such as emulsifiers, Osmanthus fragrans extraction, skimmed milk powder. Select three factors affecting product quality mostly for orthogonal designs , finally determine the best formula according to the sensory quality evaluation . The results show that: Osmanthus optimum extraction conditions were at 80 ℃ for 60min with water equaling to 60 times weight of Osmanthus; Bake peanuts in the oven at 120 ℃ for 20min, then add 10% NaHCO3 at 60 ℃ for 6h soaking , and grinding peanuts with warm water will gain the highest extraction rate of 6.2%. Take per 100g of peanut slurry as the base, adding10g sugar, 0.08g citric acid, 0.1g glycerol monostearate, 0.1g CMC-Na, 0.8g milk powder and 25g Osmanthus fragrans extraction solution ,the nutrient Osmanthus fragrans peanut milk beverage with smooth taste will be prepared Key words: Osmanthus fragrans, Peauts, Extration , Orthogonal experiment, optimum formul 目录 1 绪论 1 1.1 概述 1 1.1.1 桂花简介 1 1.1.2 花生简介 1 1.2 资源分布和药用营养价值 1 1.2.1 桂花资源和药用营养价值 1 1.2.2 花生的资源分布和药用营养价值 2 1.3 食疗功效 2 1.3.1 桂花的食疗功效 2 1.3.2 花生的食疗功效 2 1.4 国内外的研究概况及存在问题 2 1.4.1 花生国内外开发现状 2
