Notes on acidity regulator

Introduction: Acidity regulator is a kind of common food additive in our life You can see it in many foods What are the precautions of acidity regulator? What is the function of acidity regulator? Next, I will introduce it to us by the small edition of Baibo safety net Acidity regulator is also called pH regulator It is a substance used to maintain or change the pH of food The basic noodles that are added are the Acidity Regulators It is mainly used to control the acidification agent, alkali agent and the salt with buffering effect Each acidity regulator has different characteristics of light acidity and acidity Gb2760-2011 specifies the application range and maximum dosage of each acidity regulator In China, 17 kinds of Acidity Regulators are allowed to be used, including citric acid, potassium citrate, lactic acid, tartaric acid, etc Citric acid, lactic acid, tartaric acid, malic acid, sodium citrate, potassium citrate, etc can be used for all kinds of food according to normal needs The selection of acidity regulators should be in line with people's normal habits According to the flavor characteristics of food, the types, proportion and total acidity of acidizers should be determined Here's a brief introduction to the precautions of Acidity Regulators: (1) most of the acidizers ionize H +, which can affect the processing conditions of food, interact with cellulose, starch and other food raw materials, and interact with other food additives In the process of food processing, we should design the process (conditions and time) of adding sour agent, otherwise it will have adverse consequences (2) When using solid acidity regulator, its hygroscopicity and solubility should be considered so as to adopt proper packaging and formula (3) Anions can affect not only the flavor of sour agents, but also the flavor of food As mentioned above, hydrochloric acid and phosphoric acid have bitter taste, which will make the food taste worse The anionic acid often causes food to produce another flavor, which is called side flavor Generally, organic acid has a refreshing sour taste, while inorganic acid is not very palatable (4) The sour agent has certain stimulation, which can cause diseases of digestive system What's the function of acidity regulator? It's mainly to adjust the pH of food, control the acidity, improve the flavor, enhance the antioxidant effect, and prevent food from rancidity Prevent oxidation or fading reaction, stabilize color, reduce turbidity and enhance gelling property The effective application of acidity regulator is mainly controlled by the characteristics of food, usually organic acid and buffering salt It has high safety, so it is widely used We should also learn more about food safety and learn more about food additives Using food safety detector can help us to distinguish whether food ingredients are safe or not Editor in charge: he xianrob
