Problems solved by technology

The water content of fresh sweet potatoes is about 65-70%. In the sweet potato crushing stage, 3-4 times of clean water needs to be added. After separating the potato residue and starch, the remaining potato juice is discharged as waste water, resulting in a great waste of resources.
At the same time, because the production of sweet potato starch is made of fresh sweet potatoes, the processing cycle is short, so the amount of waste water generated every day is huge, and because of the high content of organic matter, the load of sewage treatment is heavy, causing great environmental pressure on the production enterprises
Although there are some reports on the utilization of sweet potato starch processing wastewater in the prior art, such as the use of sweet potato starch processing waste liquid to prepare sweet potato protein, etc., the products prepared by the utilization of sweet potato starch processing wastewater are still relatively single, and it is impossible for enterprises to achieve maximum benefit. change

Embodiment 1

[0039] 1 sweet potato processed

[0040] Select fresh and complete Jishu-21 sweet potatoes, after preliminary cleaning, then cut off the roots and pedicles, and clean them further; weigh 2kg of fresh sweet potatoes that have been processed, cut them into small pieces of about 1*1*1cm, add 3L of water, and use a beating Machine further crushed, filtered with a 200-mesh filter cloth, the filtered potato residue was washed once with 2L of water, filtered with a 200-mesh filter cloth, and the two filtrates were combined for starch separation. Add water to the potato residue after twice washing to adjust the appropriate concentration, and use it for the preparation of starch sugar and dietary fiber.

[0041] The obtained starch slurry was filtered and separated, stirred and mixed evenly, then centrifuged at 3000 rpm for 5 seconds, and the centrifuged sediment was washed with clear water, separated and dried to obtain 420 g of sweet potato starch. The centrifugal supernatant is use...

Abstract

The invention discloses a sweet potato beverage preparation method. According to the characteristics of sweet potato starch processing, a processing technology in prior art is partly adjusted as follows: material washing and selection are strengthened, and slurry quality is improved; water adding amount in a crushing stage is appropriately reduced, soluble solid content of starch slurry separation liquid is increased, and the part clear liquid is further processed into a sweet potato beverage. By pH regulation, heating and other processing, proteins in the sweet potato starch processing separation liquid can be separated, and then a clear type sweet potato beverage is prepared by allocation, or a turbid-type sweet potato beverage is prepared by direct allocation. By the process, sweet potato starch processing wastewater is turned into wealth from waste, emissions of organic wastewater with high concentration in sweet potato starch processing process can be greatly reduced, the produced sweet potato beverage can bring considerable economic benefits to enterprises, and the sweet potato beverage preparation method has very good promotion and application value in sweet potato starch processing enterprises.

Description

technical field [0001] The invention relates to a preparation method of sweet potato beverage, which belongs to the field of food and beverage processing. Background technique [0002] The nutritional and health functions of sweet potatoes make sweet potato food popular among consumers. Among them, sweet potato drinks are a kind of deep-processed sweet potato products that can meet people's needs for vitamins, minerals, and trace elements, and are low in calories. [0003] Domestic sweet potato beverages mainly include sweet potato juice beverages, sweet potato pulp suspension beverages, and sweet potato milk beverages. For example, patent CN104687180A provides a sweet potato beverage with roasted fragrance and its preparation method: sweet potatoes are washed, dried, crushed, soaked in water, filtered, and then compounded into a beverage with the filtrate; patent CN101243895A provides a processing method of sweet potato beverage , the sweet potato is washed, and then the s...
