Production of high fruit-sugar syrup from sweet kaoliang stalks

Abstract

Sorgo is a kind of high photosynthetic efficiency C4 vegetable and one of the crops with the highest output of biography. It has a long planting history in China and can be planted massively in both southern and northern part of our country due to its strong resistance and excellent adaptability. Since the sweetness of high fructose syrup is higher than sucrose, the former is a perfect natural sweetener. Corn is the main raw material of high fructose syrup in China, and the producing process includes such steps like braising and cooking, glycosylation and isomerization. Since the price of corn is relatively high and the price of sucrose is low, the production cost is relatively high, which has a certain influence with its development. However, if crushing and squeezing the culms of Sorgo, the product includes mainly the sucrose and glucose with the sugar brix of 18%-28%. Because it neední»t such complex steps as adding water and size mixing, braising and cooking and glycosylation, applying this method in the production of high fructose syrup can predigest the producing technics, shorten the producing process, reduce the investment on facilities and reduce the producing cost, and thus this method has some practical value.

Description

Technical field: [0001] The invention relates to the deep processing technology of sweet sorghum stalks and belongs to the technical field of food engineering. technical background: [0002] Sweet sorghum is high light efficiency C 4 Plants are one of the crops with the highest biological yield. According to statistics, the output of sweet sorghum per hectare is: sorghum rice 2250-6000Kg / hm 2 , fresh stems and leaves 6-10.5×10 4 Kg / hm 2 ; It has strong stress resistance and wide adaptability. It has a long history of cultivation in China and can be planted in large areas in the north and south of my country. [0003] The sweetness of high fructose syrup is higher than that of sucrose, and it is an ideal natural sweetener. Its unique flavor, crystallinity, moisture absorption, moisture retention, osmotic pressure and freezing point depression have outstanding advantages in the application of the food industry. In addition , Fructose can be directly absorbed by the human ...

AI Technical Summary

Problems solved by technology

Compared with developed countries, the production and consumption of high fructose syrup in my country are very different, and there is a great potential for development. At present, my country's high fructose syrup is mainly made of corn, which is produced by cooking, saccharification, and isomerization. Due to the double extrusion of high-priced corn and low-priced sucrose, the production cost is relatively high, and the development is affected to a certain extent.
