The function of perlite as food additive

Introduction: perlite is a kind of chemical substance, which is widely used in food What are the functions of perlite as a food additive? Perlite is a kind of food processing aid, non-toxic and tasteless non-metallic ball hollow bead, which is also a kind of food additive There are many applications in food It is frequently used in drinks and beer, which can play a filtering effect What are the functions of perlite as a food additive? Food additive perlite, also known as perlite filter aid, is a kind of powder product with a certain particle size obtained from selected mineral sand heated by purified gas, selectively expanded in vertical vertical shaft kiln, and expanded by grinding and purification Its color is white and its volume weight is 230-460kg / m3 According to the volume weight, grain size distribution and pore diameter formed by expansion, the product varieties are classified The main characteristic of perlite is that it does not contain harmful metals It has the advantages of less non-metallic components, light volume weight, fast filtration speed and good filtration effect It is widely used in beer and other beverage industries, paint and coating industries, corn oil, salad oil, carrageenan and other rapid filtration production practices Perlite is a kind of white solid powder composed of inert amorphous glass particles The main components are potassium, sodium and aluminosilicate It does not contain any organic matter It can be sterilized by high temperature combustion in the production process, and its bulk density is 20% lighter than diatomite The particles of the food additive perlite (perlite filter aid) are very irregular curls and flakes When the filter cake is formed, the porosity is 80% - 90% The particles have many pores, so they can be filtered quickly and catch the ultra-small particles below 1 micron The special advantage of perlite filter media is to retain solid while maintaining high liquid flow rate It has excellent chemical stability and no potential pollutants Its heavy metal ion content is generally 0.005ppm, so it can be used in food grade filtration If you want to know whether there is perlite in the food, you can test it with the food safety tester At the same time, if you want to know what the food additives are, Baibai safety net is your best choice Here is the most detailed knowledge of food additives Editor in charge: he xianrob
