What Do You Know About Microencapsulation? Quiz - Quiz

Here is a fantastic "What Do You Know About Microencapsulation?" quiz for you. Primarily in biology and food studies, microencapsulation (or micro-encapsulation) is a procedure in which little particles or droplets are encompassed by a covering or coating to give little cases of numerous valuable properties. On a micrometric balance, microencapsulation is basically used for joining food ingredients, cells, proteins, enzymes, and/or different materials. Best of luck with this test!
