Embodiment 1

[0018] (1) Pretreatment: select fresh yams without pathological changes and no rot, wash the soil and other dirt on the surface with clear water, then perform manual peeling, and cut into 2mm yam slices after peeling.

[0019] (2) color protection: the sliced ​​yam slices are immediately dropped into 0.4% sodium chloride solution for soaking and color protection.

[0020] (3) Hot blanching: Put the color-protected yam slices into 80°C hot water and blanch for 5 minutes.

[0021] (4) Beating: use a high-speed tissue grinder to beat the yam slices.

[0022] (5) Blending: According to the mass ratio of yam pulp and distilled water being 1:3, add distilled water of corresponding quality, and then add β-cyclodextrin, whose content is 8% of the mass of yam pulp, and blend.

[0023] (6) Homogenization: Use a homogenizer to homogenize the prepared yam slurry for 10 minutes at a speed of 6000r / min, so that the feed-liquid system is uniform and stable.

[0024] (7) Spray drying: carry...

Abstract

The invention discloses a spray-drying processing method of rhizoma dioscoreae powder, belongs to the field of deep processing of agricultural products and aims to provide a spray-drying processing method capable of retaining original color of the rhizoma dioscoreae, preparing high-purity rhizoma dioscoreae powder, achieving high production efficiency and effectively solving the problems such as low quality and unattractive color in the processing process of the rhizoma dioscoreae powder and the like. The method successively comprises a pre-treatment step, a color protection step, a blending step, a homogenization step and a spray drying step. The color protection step is characterized by putting rhizoma dioscoreae pieces into a 0.1-1.5% sodium chloride solution for soaking, putting the rhizoma dioscoreae pieces into hot water with 70-90 DEG C for hot scalding for 5-15 minutes. The rhizoma dioscoreae powder prepared by the method is rich in nutrition and can be directly brewed as a solid beverage or can be used as a raw material or an auxiliary material for processing other rhizoma dioscoreae products.

Description

technical field [0001] The invention belongs to the field of deep processing of agricultural products, in particular to a spray drying processing method of yam powder. Background technique [0002] Yam, also known as Huaishan, Chinese yam, Chinese yam, sweet potato, etc., is one of the traditional foods with the same origin in medicine and food in my country. my country is the main producer of yam in the world. Yam is rich in nutrition, containing starch, polysaccharides, polyphenols, flavonoids, vitamins, free amino acids and other ingredients, and also contains bioactive ingredients such as allantoin, mucus, niacin, choline, saponin, cholesterol, ergosterol, etc. Its medicinal effects can prevent cardiovascular diseases, improve the body's immunity, promote digestion, anti-tumor, anti-virus, anti-aging, anti-oxidation and lower blood pressure. [0003] At present, yam products are mainly dry products, mostly traditional foods, such as yam slices. A small number of enterp...
