Problems solved by technology

[0006] (2) The product has a certain degree of browning problem, or the sulfur content exceeds the standard
Yam is easy to brown during the process of peeling, slicing and drying. In order to inhibit browning and improve the whiteness of yam powder, sulfite is currently used to protect the color during the processing of yam powder, which often causes the sulfur content to exceed the standard.

Abstract

The invention relates to a production method for spray-drying Chinese yam powder without using sulfur to protecting color. The Chinese yam is prepared from fresh Chinese yam and is obtained by the steps of microwave enzyme deactivation, shelling, slicing, color protection, pulping, grinding, vacuum condensation, homogenization, spray-drying, vacuum packaging and microwave sterilization. The Chinese yam raw material is deactivated by microwave at temperature of 60 DEG C, cut to slice, and is soaked in sulfur-free color protection liquid containing phytic acid, Ethylenediaminetetraacetic acid disodium, vitamin C and citric acid, the color protection liquid and the Chinese yam slice is pulped together and is milled by a colloid mill, the Chinese yam slurry is concentrated by a vacuum condensation equipment until the content of solid is 15-25% and is homogeneously processed, homogenized liquid material is sprayed and dried by a centrifugal spray-drying machine, the obtained Chinese yam powder is packaged by vacuum and is sterilized by a microwave sterilization equipment to prepare the sulfur-free Chinese yam powder product. The invention has high production efficiency and low cost, the produced Chinese yam product has good color, high safety and complete nutrient composition, and can applied for field such as foodstuff, medicine and cosmetic product.

Description

Technical field [0001] The invention relates to a production method of sulfur-free color-protecting spray-dried yam powder. The yam powder produced by using a highly safe sulfur-free color-protecting agent for color protection and spray-drying can be applied to food, medicine and cosmetics. Background technique [0002] Yam is the traditional name for the underground tuber of D. opposita Thunb., a plant of the genus Dioscorea. It is rich in nutrients and can be used both as medicine and food. Yam is rich in nutritional and health ingredients, mainly including starch, protein, free amino acids, trace elements and other nutrients, as well as polysaccharides (including mucus and glycoproteins), allantoin, amylase, choline, 3,4-dihydroxybenzene Ethylamine, cholesterol, ergosterol, campesterol, β-sitosterol, polyphenol oxidase and other health ingredients. A large number of studies have shown that yam has various physiological effects such as immune regulation, anti-oxidation, a...
