Method for producing whole ginkgo powder

Abstract

The invention provides a method for producing whole ginkgo powder. The method comprises the steps of screening a raw material, shelling, rinsing and removing coating, performing intermediate inspection, pulping, filtering, mixing and standing, pre-gelatinizing, dewatering and drying, crushing and screening, metering and packing, and storing a finished product. The safe and sanitary whole ginkgo powder with stable quality is produced continuously in large scale without any chemical synthesis agent, and can be directly eaten or used as an intermediate raw material of other food, medicine, feed and the like; the whole ginkgo powder has good rehydration performance, high dissolution rate and high cohesiveness, and can reserve more nutrients so that the flavor and mouthfeel are closer to those of fresh ginkgo; and the production method is efficient, energy-saving, reliable and more friendly to the ecological environment.

Description

technical field [0001] The invention relates to a production method for deep processing of ginkgo fruit, in particular to a technology for continuous and large-scale production of whole ginkgo fruit powder. Background technique [0002] Due to its high moisture content, ginkgo is prone to mildew under normal natural environmental conditions, making it subject to greater restrictions and influences in various applications such as medicine, diet, and food, as well as in storage and transportation. In order to promote the greater and faster development of the ginkgo industry, relevant scholars and practitioners have made many useful explorations in the practice of deep processing of ginkgo fruits, which have been recorded in various scientific and technological documents. In terms of production technology for the processing of ginkgo powder products, at present, domestically known ginkgo powder processing methods: some use fresh ginkgo to be boiled first, then shelled, peeled, ...

AI Technical Summary

Problems solved by technology

But according to these known production methods recorded in the literature, there are indeed many problems worthy of discussion, such as: 1, from the perspective of food safety and environmental protection: the above various ginkgo powder processing methods all exist in their production process The phenomenon of using a variety of synthetic chemical reagents will inevitably affect the taste of the product, and will cause safety hazards to consumers of the product; and the discharge of wastewater containing various chemical synthetic agents is bound to be unfriendly to the natural environment.

2. From the perspective of energy saving: the spray drying or freeze drying equipment that is matched with the drying process has the problems of high energy consumption, low thermal efficiency, and large investment in equipment, resulting in a large waste of heat and electricity energy, and the production cost is pushed up.
