Question

Fish byproduct used in cleaning the wine

• A. Fish guano
• B. Shagreen
• C. Isinglass
• D. Ovaprim

Hint:

Common fish by-products: \[ \boxed{ \begin{aligned} &\text{Isinglass} &&\rightarrow \text{Wine/beer clarification} &\text{Shagreen} &&\rightarrow \text{Leather} &\text{Fish guano} &&\rightarrow \text{Fertilizer} &\text{Ovaprim} &&\rightarrow \text{Induced breeding} \end{aligned} } \]

Answer 1

The Correct Option is C

Step 1: Recall the use of fish by-products. Isinglass is a collagen-rich substance obtained from the swim bladder of certain fishes. It is widely used as a clarifying (fining) agent in \[ \boxed{\text{Wine and beer}.} \]

Step 2: Eliminate the remaining options. \[ \begin{aligned} \text{Fish guano} &\rightarrow \text{Organic manure} \text{Shagreen} &\rightarrow \text{Leather prepared from fish skin} \text{Ovaprim} &\rightarrow \text{Hormonal preparation used for induced breeding in fishes} \end{aligned} \]

Step 3: Choose the correct option. Therefore, \[ \boxed{(C)\ \text{Isinglass}} \] is the correct answer.
