In fruit juice extraction, what is the purpose of using pectinases?
Understand the Problem
The question asks about the application of pectinases in fruit juice extraction. Specifically, it's asking what role pectinases play in this process, with the options focusing on preservation, sugar content, flavor, and cell wall breakdown/juice clarification.
Answer
Pectinases improve juice quality and yield by clarifying juice and speeding up extraction.
In fruit juice extraction, pectinases are used to improve juice quality and yield. They clarify juice and speed up extraction by breaking down pectin in fruit pulp.

More Information
Pectinases are a family of enzymes that break down pectin, a polysaccharide found in plant cell walls. By degrading pectin, pectinases help to release juice from fruit pulp, clarify the juice by reducing cloudiness, and improve the overall yield and quality of the final product. They are also used in winemaking.
Tips
A common mistake is to think pectinases only clarify juice, but they also aid in extraction and improve yield.
