Embodiment 1

[0030] With fresh garlic as raw material, such as figure 1 Shown technological process, specifically carry out according to the following steps:

[0031] The first step is pretreatment: put each kilogram of fresh garlic cloves in 2.5 liters of drinking water, soak for 4 hours, rinse with running water to remove impurities such as soil and garlic skin, control dry clear water, place on a steamer, and steam until round Steam for another 10 minutes, subject to steaming thoroughly and inactivating alliinase.

[0032] The second step is to prepare the garlic polysaccharide extract: add the steamed garlic cloves and cooking water to the beater to make garlic pulp of 100-150 mesh; filter the garlic pulp with a 250-mesh filter cloth (or bag filter) to obtain garlic Crude polysaccharide extract. The crude garlic extract is centrifuged at 4000 rpm for more than 20 minutes, and the supernatant obtained is filtered with a membrane with a molecular weight cut-off of 20,000 Daltons, and the...

Embodiment 2

[0038] With dehydrated garlic slices as raw material, proceed as follows:

[0039] The first step is to process the dehydrated garlic slices: soak the dehydrated garlic slices in 8 times drinking water for 1 to 2 hours, and boil for 10 minutes. Steam to soften and inactivate alliinase shall prevail.

[0040] The second step is to prepare the garlic polysaccharide extract: use the steamed garlic slices to make a 100-150-mesh garlic pulp with a beater, and filter it with a 250-mesh filter cloth to remove impurities such as garlic tissue particles and garlic skin to obtain a crude garlic extract. . The crude extract is centrifuged at 4000 rpm for more than 20 minutes, and the obtained supernatant is filtered through an inorganic membrane with a molecular weight cut-off of 20,000 to obtain a transparent garlic polysaccharide extract.

[0041] The third step is edible grade hydrochloric acid and citric acid to adjust the pH of the above-mentioned refined garlic polysaccharide ext...

Embodiment 3

[0048] Using fresh garlic as raw material, follow the steps below:

[0049] The first step is to prepare garlic polysaccharide extract: put 5000 grams of fresh garlic cloves and 12.5 liters of pH3 hydrochloric acid aqueous solution into a beater to make garlic pulp of 100-150 mesh, and process it through a bag filter and a press to remove Garlic tissue granules, garlic skin and other impurities are obtained to obtain garlic crude extract. A hydrocyclone is used to separate and remove suspended impurities, and the obtained supernatant is filtered with a plate and frame press (pressure 2 MPa) to obtain a transparent garlic polysaccharide extract.

[0050] The second step is to prepare the garlic polysaccharide extract: the steamed garlic slices are made into a 100-150-mesh garlic pulp with a beater, and filtered with a 250-mesh filter cloth to obtain a crude garlic extract. The crude extract is centrifuged at 3000 rpm for more than 20 minutes, and the obtained supernatant is fi...

Abstract

The invention discloses a garlic low poly fruit sugar manufacturing method. It includes the following steps: processing various garlic materials to gain garlic polysaccharide coarse extracting solution; fine processing to gain transparent refine garlic polysaccharide extracting solution; hydrolyzing with 1.0-2.5 pH value to make reducing value reach 10-35%; then gaining the garlic low poly fruit sugar solution with 3-10 polymerization degree. The product can be helpful to delay garlic material overstock, exploit medicine or health food used garlic low poly fruit sugar as material, and greatly increase addition value of the garlic further processed product.

Description

technical field [0001] The invention belongs to the field of extraction, separation and modification of natural products, and particularly relates to a method of using fresh or dehydrated garlic, or garlic residue after extracting garlic essential oil (volatile oil), or waste liquid after extracting alliin, etc. A method for producing garlic fructooligosaccharides from raw materials. Background technique [0002] Garlic (Allium sativum L.) has the functions of appetizing and invigorating the spleen, dispelling cold and dampness, reducing swelling and dispelling toxins, etc. It is often used to treat diarrhea, whooping cough, cold cough, athlete's foot and other diseases. Modern medicine and nutritional studies have proved that garlic has the functions of lowering blood fat, preventing arteriosclerosis, preventing and treating coronary heart disease, cerebral thrombosis, anti-inflammatory and bactericidal, anti-cancer, improving immunity, protecting ...
