The invention further provides an encoded protein and application of the banana fruit starch branching enzyme gene MaSBE2.3. The banana fruit starch branching enzyme gene MaSBE2.3 can improve the quality of fruit amylopectin and increase the content of glucose and fructose of fruits, for example, the banana fruit starch branching enzyme gene MaSBE2.3 is introduced into the banana fruits, the gene MaSBE2.3 is overexpressed, accordingly, the activity of a starch branching enzyme (SBE) is improved, and the expression quantity of the MaSBE2.3 and the content of the amylopectin are increased; and therefore, the banana fruit starch branching enzyme gene MaSBE2.3 has important significance for regulating the content of the amylopectin, or increasing the yield of crops, improving the quality of the amylopectin and culturing high-quality new banana species, and a gene resource candidate is provided for improving the quality of the amylopectin of bananas or other fruits.

The invention discloses a low-temperature green raisin washing and sterilizing method. Green raisins are washed and sterilized through precooling saline solutions after being precooled, and then are dried through cold air. The method has the advantages that according to the characteristics that the green raisins are high in fructose content, high in reconstitution performance, prone to browning (changing color) when encountering high temperature, high humidity and strong ultraviolet rays, and prone to deformation, the invention provides the green raisin dry and cold method washing and non-thermal sterilization processing method, the liquid saline water, namely edible salt is adopted for low-temperature sterilization, after the green raisins are washed through the method, attachments on the green raisins are washed off to the maximum extent, rehydration of the green raisins can be reduced, the green raisins are kept from browning, the hygiene and microbiological indicators can reach the national food safety and hygiene standards, and the original color and lustre, flavor and shape keep unchanged.

The invention provides a technology for producing fructose-glucose syrup containing 90% of fructose from rice. The technology comprises steps of: rice immersing and milling; a first spray liquefaction; a second spray liquefaction; saccharification; a first decolouring; a first ion exchange; isomerization; a second decolouring; a second ion exchange; nanofiltration membrane separation; reverse osmosis membrane separation; and last evaporation concentration for obtaining fructose-glucose syrup containing 90% of fructose. The invention overcomes defects of a prior art, such as multiple steps, large energy consumption, strong labor intensity, large waste water discharge and high concentration of discharged waste water, etc. A nanofiltration membrane separation and a reverse osmosis technology are employed, and technical processes are optimized, so as to simplify process steps, lower energy consumption and increase output.

The invention relates to a method for increasing the content of fructose in konjak bulbs. The method is characterized in that the low-temperature stress freezing treatment is carried out for 72 hours at the temperature of 2 DEG C below zero-4 DEG C below zero before the konjak bulbs are subjected to fructose extraction. According to the method, cells are induced to start a physiological reaction program for converting other matters into the fructose so that the content of the fructose in the konjak bulbs is greatly increased and further more fructose can be extracted from the bulbs with the same quantity and quality. The method is an ideal method for more efficiently extracting more fructose from the konjak bulbs.

The invention discloses the application of soybean purple acid phosphatase gene GmPAP35, which belongs to the field of genetic engineering. The present invention clarifies the function of GmPAP35 involved in carbon metabolism in plants through the functional analysis of GmPAP35 in whole soybean plant transformation materials. Overexpression of GmPAP35 can increase soybean plant height, glucose and fructose content in plants, thereby increasing soybean biomass and phosphorus uptake, improving soybean phosphorus efficiency, and laying a theoretical foundation for cultivating new varieties of phosphorus-efficient transgenic crops. The invention has the new application of promoting carbon metabolism ability of crops through transgenic technology, thereby improving plant phosphorus efficiency, achieving fertilizer saving and high yield, and has important theoretical and practical significance for the development of environment-friendly sustainable agriculture.
