Why would a fruit juice manufacturer add pectinases to their fruit juice?
A
To enhance the color of the juice
B
To increase the sweetness of the juice
C
To preserve the juice for a longer shelf life
D
To clarify the juice by breaking down pectin
Verified step by step guidance1
Understand the role of pectin in fruit juice: Pectin is a structural polysaccharide found in the cell walls of fruits. It contributes to the cloudiness and viscosity of fruit juices.
Identify the function of pectinases: Pectinases are enzymes that break down pectin into simpler molecules, such as galacturonic acid. This process reduces the cloudiness and viscosity of the juice.
Consider the desired properties of fruit juice: Manufacturers often aim for a clear, less viscous juice to improve its appearance and texture, making it more appealing to consumers.
Relate the use of pectinases to juice clarification: By adding pectinases, manufacturers can effectively break down pectin, resulting in a clearer juice with a smoother texture.
Conclude the reason for adding pectinases: The primary reason a fruit juice manufacturer would add pectinases is to clarify the juice by breaking down pectin, enhancing its visual appeal and drinkability.
