Embodiment 1

[0018] A kind of sweet potato quick saccharification method, comprises the following steps:

[0019] (1) Disinfection and sterilization: remove the mud on the surface of the sweet potato, and wash it with pure water, then spray the sweet potato with a large amount of Bordeaux mixture dilution to carry out disinfection and sterilization;

[0020] (2) Transplantation enzyme source: apply glucoamylase to the root navel of sweet potato and paste it. The glucoamylase is sterilized and soaked in 1% glucoamylase liquid cotton balls and stickers;

[0021] (3) Microwave irradiation: Carry out microwave irradiation 1min under the condition of 400W to the sweet potato after pasting treatment, activate glucoamylase;

[0022] (4) Anaerobic saccharification: the sweet potatoes irradiated by microwaves were moved into a temperature-controlled room, fed with nitrogen, and left to stand at 30° C. for 48 hours to carry out anaerobic saccharification;

[0023] (5) Low-temperature storage: after...

Embodiment 2

[0025] A kind of sweet potato quick saccharification method, comprises the following steps:

[0026] (1) Disinfection and sterilization: remove the mud on the surface of the sweet potato, and wash it with pure water, then spray the sweet potato with a large amount of Bordeaux mixture dilution to carry out disinfection and sterilization;

[0027] (2) Transplantation enzyme source: paste processing on sweet potato root navel position with glucoamylase application, this glucoamylase application is made of cotton ball and sticky paper that sterilizes and soaks the glucoamylase liquid that concentration is 2%;

[0028] (3) Microwave irradiation: Carry out microwave irradiation 0.5min under the condition of 600W to the sweet potato after pasting treatment, activate glucoamylase;

[0029] (4) Anaerobic saccharification: the sweet potatoes irradiated by microwaves were moved into a temperature-controlled room, fed with nitrogen, and left to stand for 24 hours at 35°C for anaerobic sac...

Abstract

The invention relates to a fast saccharification method for sweet potatoes. The fast saccharification method includes the steps of firstly, sterilizing, to be more specific, cleaning mud on the surface of the sweet potatoes, washing the sweet potatoes with purified water, and spraying Bordeaux mixture diluent with the ratio of copper sulfate to quick lime being 1:(3-5) to the sweet potatoes to sterilize the sweet potatoes; secondly, transplanting an enzyme source, to be more specific, adhering a saccharifying enzyme patch to the tuberous root umbilicus part of each sweet potato; thirdly, performing microwave irradiation, to be more specific, subjecting the sweet potatoes obtained after the second step to microwave irradiation for 0.5-1 minute to activate the saccharifying enzymes; fourthly, performing anaerobic saccharification, to be more specific, transferring the sweet potatoes obtained after the microwave irradiation into a temperature control room, feeding nitrogen into the temperature control room, and subjecting the sweet potatoes to standing in an environment of 25-35 DEG C for 24-48 hours to perform anaerobic saccharification; fifthly, performing low-temperature storage, to be more specific, after the anaerobic saccharification, storing the saccharified sweet potatoes in a low-temperature room of 5-10 DEG C for 5-10 days. The fast saccharification method has the advantages that the microwave irradiation and saccharifying enzyme catalyzing technologies are utilized, the defects that the prior art is low in saccharification efficiency and speed are overcome, the saccharification time of the sweet potatoes is shortened greatly, and the difficulty that the sweet potatoes are prone to rot during saccharification is solved effectively.

Description

technical field [0001] The invention relates to the technical field of sweet potato saccharification technology, in particular to a fast sweet potato saccharification method. Background technique [0002] In order to increase the sweetness of sweet potatoes without adding other sugars, sweet potatoes must be saccharified. The degree of saccharification is an important index to evaluate the quality of sweet potato. The current sweet potato saccharification mainly uses winter storage for natural saccharification, that is, the sweet potatoes are collected and stacked in the potato cellar for low-temperature saccharification. The time is usually as long as 1-2 months. The production efficiency is low, the saccharification speed is slow, and it is easy to be infected with bacteria and rot; The saccharification bin is used for saccharification, but the operation of this method is relatively complicated and the energy consumption is relatively large.
