Precautions for enzyme preparation

Introduction: Although we use enzyme preparation in many fields of production and life, not only in the food industry, industry and agriculture, what are the precautions for using enzyme preparation? What are the functions of enzyme preparation? Let's talk about it The main enzyme preparations in the domestic market include amylase, protease, cellulase, pectinase, β - glucanase, phytase, etc At present, except for the single product of phytase, most of the feed enzyme preparations are compound preparations containing multiple enzymes Enzyme preparation is a kind of substance with enzyme characteristics extracted from biology Its main function is to catalyze various chemical reactions and improve food processing methods Enzyme preparation is a kind of protein with biocatalytic ability extracted from animals, plants and microorganisms It has high efficiency, specificity and activity under suitable conditions (pH and temperature) What are the precautions for the use of enzyme preparation? According to the introduction of Baibai safety net, enzyme preparation itself is a kind of protein, and any factors affecting the protein will affect the activity of enzyme preparation The activity of enzyme increased with the increase of temperature, but when the temperature reached a certain level, the enzyme denatured and lost its activity Generally, the optimum temperature of enzyme activity is 30-45 ℃, when the temperature is over 60 ℃, the enzyme will denature and lose its activity PH also has an effect on the activity of enzyme When other conditions remain unchanged, the activity of enzyme is the highest in a certain range of pH The optimum pH value of enzyme activity is close to neutral (6.5-8.0) However, there are some exceptions, such as pepsin with the optimal pH of 1.5 Iodoacetic acid, ferricyanide and heavy metal ions can combine with or react with the necessary groups of the enzyme, so that the enzyme loses its activity Therefore, in the process of feed production, we must pay attention to the influence of temperature, acid-base, heavy metal ions and other factors on enzyme preparation in order to achieve the best use effect of enzyme preparation We must pay attention to the precautions of enzyme preparation When using enzyme preparation correctly, we must strictly control the dosage The dosage is too small to achieve the effect Too much dosage will cause waste If not used properly, some enzyme preparations will even appear abnormal What is the function of enzyme preparation? Food enzyme preparation is mainly to improve food quality, taste, flavor, freshness, food adaptability and other food properties, extend the storage period of food and prevent food deterioration You may not know much about enzyme preparation, because enzyme preparation is mainly used in the production field, which is rarely used by ordinary people If you want to know more about enzyme preparation, you can learn more about food safety, which is useful for understanding enzyme preparation correctly Food safety detector can also help us to detect the content of enzyme in food Editor in charge: he xianrob
