Description

Technical Field

[0001] The utility model relates to the field of yogurt fermentation auxiliary devices, in particular to a plastic bag for yogurt fermentation which is easy to take out. Background Art

[0002] Yogurt, also known as fermented milk, refers to a large category of dairy products made from animal milk such as cow's milk through the lactic acid fermentation process, mainly including sour milk, active milk, cheese, sour cream, etc. Fermented milk containing a large number of beneficial active bacteria is one of the ideal foods for modern humans with both nutritional and health functions. Fermented milk (yogurt) is an acidic curd-like product fermented from milk and dairy products under the action of characteristic bacteria. The characteristic bacteria of this type of product must exist in large quantities during the shelf life and continue to survive and be active. Therefore, fermented milk refers to a curd-like product made by adding lactic acid bacteria (Lactobacillus bulgaricus and Streptococcus thermophilus) to milk and fermenting it with lactic acid. The finished product must contain a large number of corresponding active microorganisms.

[0003] At present, people ferment yogurt by themselves in their family life. In order to make the fermentation more hygienic, they usually use plastic bags to put the fermentation materials into a constant temperature device for fermentation. After the fermentation is completed, the yogurt is removed by taking out the plastic bag. The existing food plastic bags are made of relatively soft materials. Directly pulling the plastic bag after the yogurt fermentation is easy to cause damage to the plastic bag. Therefore, the market urgently needs to develop a plastic bag for yogurt fermentation that is easy to take out to help people solve the existing problem. Utility Model Content
