Preparation method of ginkgo composite breakfast powder suitable for middle-aged and elderly people
Technical Field
The invention belongs to the technical field of food processing, and relates to a preparation method of ginkgo composite breakfast powder suitable for middle-aged and elderly people.
Background
With the progress of society and the rapid development of economy, more and more breakfast products appear on the dining tables of people, from the traditional black sesame paste to the current milk, bread, biscuits and the like. However, these breakfast products are not well suited for the elderly, as the nutrition they provide is not very complete and may cause malnutrition in the elderly. Therefore, there is a need to develop a breakfast powder which is suitable for middle-aged and elderly people and can provide sufficient nutrition for middle-aged and elderly people.
Ginkgo is a gymnosperm, which is one of the unique ancient and precious tree species in China and is called as "activating stone". The ginkgo tree has no fruit, the ginkgo fruit is actually the seed of ginkgo, and the ginkgo fruit is also called ginkgo, and is one of famous dry fruits in China. The gingko nut has rich nutrition, contains protein, starch, vitamins, calcium, potassium, selenium and other elements, and is taken as a good product for preserving health and prolonging life. It is worth mentioning that the ginkgo also contains physiologically active substances, such as flavone, ginkgol and the like, and the flavone has the functions of reducing blood pressure, reducing blood viscosity, eliminating free radicals, improving memory and the like; the bilobalide has strong inhibition effect on carcinogenic factors and has certain curative effect on leukemia, tumor and the like; the phenolic substances have antibacterial and anti-inflammatory effects. Therefore, the ginkgo biloba is very suitable for the middle-aged and the elderly to eat.
For a long time, toxic components such as ginkgolic acid contained in ginkgo can cause poisoning and even endanger life after being eaten excessively. Therefore, the development and utilization of ginkgo resources are limited. To date, ginkgo biloba is mainly used for cooking or as a medicine, and the development of food products using it is essentially blank. However, ginkgo has rich nutrition and health care components, and is a raw material very suitable for making breakfast powder.
