Abstract
The invention discloses instant nutrient purple potato chips and a preparation method thereof. The purple potato chips are prepared from raw materials, namely purple potato whole syrup, white granulated sugar, starch, soybean protein isolate, a thickener, a compound mineral enhancer, a compound vitamin enhancer and water according to a certain mass part ratio. The preparation method comprises thefollowing steps of: A, selecting fresh and full purple potato as raw materials; B, washing and trimming, namely washing by using a washer; C, slicing and conserving color; D, heating and cooking, namely softening a tissue structure of the purple potato, treating, inactivating polyphenol oxidase and amylase which are inherent in the purple potato to protect purple potato pigments and purple potatostarch; E, beating, mixing and inflating, namely crushing heated and cooked purple potato pieces in a beater into the purple potato whole syrup; F, refining and homogenizing by using a colloid mill; G, drying and scraping slices by using a roller; H, performing secondary drying; and I, packing. The instant nutrient purple potato chips has a rational formula, wide sources of the raw materials, lowcost, excellent flavor, beautiful color, high content of the purple potato pigments and high content of nutritional ingredients, and is rapidly rehydrated and instant, and the product has a porous structure.
Description
technical field [0001] The invention relates to the technical field of food and purple potato processing, and more specifically relates to an instant nutritional purple potato oatmeal and a preparation method for instant nutritional and health purple potato chips. Background technique [0002] Purple sweet potato (Ipomoea Batatas poir), also known as purple sweet potato, purple sweet potato, purple heart sweet potato and black sweet potato, is a special variety of sweet potato. In 1997, Chinese sweet potato researchers successfully introduced purple sweet potato to my country from the Kyushu Agricultural Experimental Field of the Ministry of Agriculture, Forestry and Fisheries of Japan. It was then named "Chuanshan Purple Sweet Potato". Many new varieties of purple sweet potato with high yield and purple sweet potato anthocyanidin (Purple-Fleshed Sweet Potato Anthocyanidin) have been bred through selection and breeding. Hubei, Jiangxi, Sichuan, Chongqing, Guangxi, Yunnan, Sh...
