Problems solved by technology

However, as the population continues to increase, land resources are decreasing day by day, and food security is becoming a worldwide problem, it is not feasible to expand the planting area of ​​konjac alone in actual production.
In addition, after many years of planting, soft rot has occurred in most plots in the konjac production area, and it is no longer suitable for planting konjac.

Embodiment 1

[0028] Before extracting fructose from the konjac bulbs, put the konjac bulbs into a carton (the top of the carton is open and unsealed) and put them in the refrigerator, then freeze them at -4°C for 72 hours. Then carry out the extraction of fructose by the method for prior art.

Embodiment 2

[0030] Before extracting fructose from the konjac bulbs, put the konjac bulbs into a carton (the top of the carton is open and unsealed) and put them in the refrigerator, then freeze them at -2°C for 72 hours. Then carry out the extraction of fructose by the method for prior art.

Embodiment 3

[0032] Before extracting fructose from konjac bulbs, put the konjac bulbs into a carton (the top of the carton is open and unsealed), put them in the refrigerator, and freeze them at -3°C for 72 hours. Then carry out the extraction of fructose by prior art method.

Abstract

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.

Description

technical field [0001] The invention relates to a method for increasing the fructose content in konjac bulbs. Background technique [0002] In plant physiological activities, fructose mainly stores nutrients and provides nutrients; increases the concentration of solutes in cells and reduces the freezing point of cell solutions; regulates cell osmotic pressure and buffers excessive dehydration of cytoplasm; effects on cell damage. [0003] The purpose of people planting konjac is mainly to extract sugar substances from konjac bulbs. The fructose in konjac bulbs is transformed and accumulated from photosynthetic organic matter, and it mainly supplies the nutrients needed for the growth of konjac plants and the substances needed for morphogenesis. In autumn and winter, 30 to 40 days after the konjac plants fall, when the nutrients in the fleshy roots fully return to the main bulbs, start digging konjac. After harvesting, wash off the soil attached to the surface of the bulb,...
