Embodiment 1
[0045] The preparation method for the joint extraction of alliin and allicin is carried out according to the following process steps:
[0046] Raw material pretreatment:
[0047]Inject 100kg of water into the pool, drop into 0.5kg of hydroxylamine hydrochloride, stir and mix; at a stirring rate of 100rpm, continuously inject glacial acetic acid into the pool until the pH value of the solution in the pool is 3.5, and obtain the enzyme activity inhibitor;
[0048] Peel off the outer skin of the garlic, wash and remove; weigh 50kg of intact and clean garlic grains, put them in the enzyme inhibitor, and soak them at 20°C for 6 hours; after soaking, transfer the garlic grains and enzyme inhibitors to the grinder , the pulverizer is equipped with a cooling jacket, so that the temperature in the pulverizer is controlled at 1°C, and the pulverizer pulverizes the homogenate to obtain the raw material of mashed garlic;
[0049] Add 50kgNa / K phosphate buffer solution to the garlic raw m...
Embodiment 2-8
[0062] The difference between the preparation method of alliin and allicin combined extraction and that of Example 1 is that the process parameters in the raw material pretreatment step are different, and the specific process parameters are shown in the following table.
