Description

technical field [0001] The invention relates to a method for debittering and color protection of ginkgo and low-temperature processing. Background technique [0002] Ginkgo biloba is one of the first batch of foods that have both medicine and food from the Ministry of Health. Ginkgo biloba can be used as dried fruit, medicinal food and dishes. Ginkgo biloba can have the effects of constricting lung energy, relieving asthma and cough, stopping white turbidity, shrinking stool, nourishing kidney and brain, and dilating blood vessels. , but due to the lack of research and development technology for ginkgo products, there are few ginkgo processing enterprises, small production scale, low technical content, few product varieties, and most of them are primary processed products, only canned ginkgo nuts, soft-packed nuts, ginkgo drinks, etc. Few kinds of products can enter the market, and the economic benefits of ginkgo are far from being discovered, resulting in a backlog of a lar...
