Correct option is A
The correct answer is: (A) Pectin content
The Jelmeter test is a method used to estimate the pectin content in fruit juices and extracts. Pectin is a natural carbohydrate that plays a crucial role in the gel formation of jams and jellies.
Information Booster:
- The Jelmeter is a long, graduated glass tube that measures the flow rate of a liquid sample under gravity.
- Higher viscosity indicates a higher pectin content, which is essential for jelly formation without adding extra commercial pectin.
- This test is commonly used in fruit processing industries to assess the quality of fruits like apples, guavas, and citrus fruits for jam and jelly production.
Knowledge Booster:
Sugar content: Measured using a refractometer or Brix hydrometer, which determines the sugar concentration in fruit juices and syrups.
TSS (Total Soluble Solids) content: It includes sugars, acids, and other dissolved solids in a solution, commonly measured using a Brix refractometer in fruit processing.
Acid content: Determined through titration methods using sodium hydroxide (NaOH) to measure the acidity level in fruit juices and other food products.
