preparation example Construction

[0028] In order to solve the above problems, the present invention provides a method for preparing longan meat superfine powder, comprising the following steps:

[0029] S1: Take the longan pulp and soak it in edible ethanol according to the ratio of material to liquid for pretreatment;

[0030] S2: After soaking, wash the pulp surface with distilled water, put it into a beater for beating, and obtain longan pulp homogenization;

[0031] S3: putting the obtained longan pulp homogenate into an oven for drying, and then softening at room temperature to obtain a dried pulp homogenate;

[0032] S4: pulverize the dried pulp homogenate with a universal grinder to obtain longan pulp coarse powder;

[0033] S5: Superfinely pulverize the longan pulp coarse powder described in step S4 to obtain longan pulp superfine powder.

[0034] Because the longan pulp contains many alcohol-soluble impurities, such as pigments and oligosaccharides, in addition to polysaccharides, therefore, in the...

Embodiment 1

Abstract

The invention discloses longan pulp superfine powder and a preparation method thereof. The preparation method comprises the following steps: S1, taking longan pulp, and soaking the longan pulp with edible ethanol according to a material-liquid ratio for pretreatment; S2, washing the surface of the pulp with distilled water after soaking, and pulping in a pulping machine to obtain longan pulp homogenate; S3, drying the obtained longan pulp homogenate in a drying oven, and then softening at room temperature to obtain dried pulp homogenate; S4, crushing the dried pulp homogenate by using a universal crusher to obtain longan pulp coarse powder; and S5, carrying out superfine grinding on the longan pulp coarse powder obtained in the step S4 to obtain the longan pulp superfine powder. The prepared longan pulp superfine powder is uniform in particle size, small in viscosity, large in solubility and small in polysaccharide loss, the biological activity and nutritional ingredients of the longan pulp can be reserved to the maximum extent, and the preparation method is simple, low in production cost and suitable for industrial development.

Description

technical field [0001] The application belongs to the technical field of agricultural product processing, and in particular relates to a superfine powder of longan meat and a preparation method thereof. Background technique [0002] Longan (Dimocarpus longan Lour) is a special fruit that is not only a health food but also a nourishing medicine. Longan meat is the aril of longan. It has certain therapeutic value. It is sweet in taste and warm in nature. Relevant studies have found that its main functional components are polysaccharides, and longan pulp polysaccharides have various functions such as immune regulation, memory enhancement, and anti-oxidation. Therefore, the research on polysaccharides from longan pulp has attracted widespread attention. The polysaccharide content in longan pulp can be as high as 35%, which can significantly regulate the intestinal mucosal immune system, enhance the function of the immune system, and improve learning and memory functions by reg...
