Novel process for deodorizing garlic oil

Abstract

Aiming to solve the problems, such as incomplete deodorization and low recovering rate, existing in the prior process of deodorizing garlic oil, the invention provides a novel process for deodorizing garlic oil. The process comprises the following steps: (1) grinding garlic materials into garlic pulp, and adding water to obtain a pulp liquid; (2) distilling the pulp liquid at 120 to 135 DEG C and obtaining a first deodorized distillate; (3) and conducting the oil-water separation and the electromagnetic wave irradiation on the first deodorized distillate so as to obtain a second deodorized distillate. Furthermore, the frequency of electromagnetic wave is 2400-2500 MHz, and the electromagnetic wave irradiation can be conducted before the oil-water separation or after the oil-water separation. The novel process provided by the invention for deodorizing garlic oil is a physical method and has the advantages of good deodorizing effect, convenient operation, high efficiency, suitability for the industrial large-scale production and no foreign chemical substance residues.

Description

technical field [0001] The invention relates to a preparation process for deodorizing garlic oil. Background technique [0002] Garlic (A llium sativam L) is a plant of the Liliaceae family, and its underground stems can be used for both medicine and food. Garlic contains about 0.2% volatile garlic oil. Its main components include allicin and a variety of sulfide compounds composed of allyl, propyl, and methyl groups. Among them, propylene sulfide has a bactericidal effect. This sulfur-containing compound is a natural broad-spectrum antibiotic, which has various drug functions such as improving the body's immunity, lowering blood fat, and anti-tumor. Therefore, all countries in the world attach great importance to the extraction and deep processing of garlic oil. my country is a major garlic production and export country, and has great potential for deep processing of garlic. Some people say that "in addition to the nasty smell, the actual value of garlic is higher than go...

Problems solved by technology

[0004] After years of hard work, different laboratories have established a variety of different garlic deodorization methods, such as extraction deodorization method, magnesium hydroxide deodorization method, etc., The chemical substances used in these deodorization methods often have residues; alcohol heating deodorization method, acetic acid deodorization method, boiling deodorization method, the deodorization effect of these methods is relatively poor; Residual odor

There are also some comprehensive methods at the laboratory level, but these methods only stay at the laboratory level, the process is complicated, the yield is low, and it is not suitable for large-scale production in factories
