Method for decontaminating dehydrated garlic products

Abstract

The invention discloses a method for decontaminating dehydrated garlic products. The method for manufacturing the dehydrated garlic products includes steps of soaking and disinfecting selected garlicin acidic electrolytic water with the pH (potential of hydrogen) value of 2-4 for 5-15 min and then cleaning the garlic by the aid of pure water; placing the garlic in ozone water, carrying out cooling treatment on the garlic for 5-10 minutes and splitting the garlic; secondarily treating split raw materials by the aid of ozone water for 20-40 minutes; draining raw materials treated by the aid ofthe ozone water, then carrying out stepped temperature control drying on the raw materials, in other words, drying the raw materials at the temperatures of 110-120 DEG C for 1-2 hours, gradually reducing the temperatures until the temperatures reach 60-80 DEG C, and continuing to dry the raw materials until the moisture contents of the raw materials are reduced and reach 5-8%. The method has the advantages that the quantity of germs carried by the garlic can be reduced by 60%-67%, late sterilization can be omitted, the sterilization intensity of the method is far lower than the sterilization intensity of conventional processing technologies, dehydrated garlic which is subjected to contamination treatment by the aid of the method is little in color and nutritional component change, but thetotal colony count of the dehydrated garlic can be obviously reduced and reaches high standards, and the problem of dull sale due to the fact that the total colony count of existing garlic products exceeds standards can be effectively solved by the aid of the method.

Description

technical field [0001] The invention relates to the field of vegetable dehydration, in particular to a method for reducing bacteria of dehydrated garlic products. Background technique [0002] Garlic is not only a condiment, but also a natural medicine. It is a commonly used condiment in the diet and food processing of consumers at home and abroad. At present, the garlic products exported by our country are mainly dehydrated garlic flakes, garlic granules, garlic powder and so on. Although the output of garlic in my country is large, the collection of raw materials has not formed a corresponding system. The quality of processed raw materials varies greatly, and pollution is prone to occur in the processing and cleaning process, resulting in the total number of colonies of finished garlic products not being kept at a relatively low state. As the quality requirements of export products continue to increase, the requirements for microbial content are also gradually raised. In ...
