Abstract

The invention relates to a microbial liquid foaming agent. The microbial liquid foaming agent is characterized by being prepared from, in parts by weight, 10-15 parts of sugar, 10-20 parts of peptone,5-10 parts of yeast extract powder, 5-15 parts of a yeast strain liquid, 0.2-1 part of a foam stabilizer and 40-60 parts of water. The foaming agent has the characteristics of simple preparation process, low reaction energy consumption, high foaming capacity and the like and has wide application prospects. The foaming agent also comprises the foam stabilizer, and more uniform, fine and stable foam can be obtained. Required materials are widely sourced and low in cost, the requirement for stirring equipment is low, the foam is prepared from probiotics and nutrient substances, the foaming agentis non-toxic, harmless and wide in application range, and the problems of high cost, poor foam stability and single application range of existing foaming agents are solved.

Description

technical field [0001] The invention belongs to the technical field of microorganisms and foaming agents, and in particular relates to a foaming agent for microbial bacterial liquid and a preparation method thereof. Background technique [0002] Foaming agents can be divided into three categories: chemical foaming agents, physical foaming agents and surfactants. The main difference between chemical blowing agents and physical blowing agents is whether a chemical reaction occurs when the bubbles are created. A chemical blowing agent usually decomposes a certain chemical substance under certain conditions and produces gases such as carbon dioxide, nitrogen, and oxygen; a physical blowing agent forms foam pores through a change in the physical form of a certain substance, that is, through the compressed gas It is formed by expansion, volatilization of liquid or dissolution of solid; surfactant has high surface activity, can effectively reduce the surface tension of liquid, and...
