Question

During the manufacturing of 1 kg of Shrikhand if 180 grams of solids is contributed by chakka, how much sugar should be added to comply with the total solid level of the product as per the Food Safety and Standards (Food Product Standards and Food Additives) Regulations, 2011

• A. 580 g
• B. 300 g
• C. 250 g
• D. 400 g

Hint:

To solve this quickly, remember the FSSAI total solids limit for Shrikhand:
- Minimum Total Solids = 58%.
- For 1000 g Shrikhand, TS = 580 g.
- Subtract chakka solids (180 g) from 580 g to find the required sugar: \(580 - 180 = 400\text{ g}\).

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Shrikhand is a popular semi-soft, sweetish-sour fermented dairy dessert prepared from chakka (drained dahi/yoghurt curd) mixed with sugar, flavorings, and spices.
The Food Safety and Standards Authority of India (FSSAI) establishes specific compositional standards for Shrikhand to ensure its quality and authenticity.
Key Formula or Approach:
According to the Food Safety and Standards Regulations, 2011:
The total solids (TS) content in Shrikhand must not be less than 58.0% by weight:
\[ \text{Minimum Total Solids Required} = 58.0\% \text{ of the final product weight} \]
For 1 kg (1000 g) of Shrikhand, the total solids must be at least:
\[ \text{Total Solids Required} = 1000\text{ g} \times 0.58 = 580\text{ g} \]
These solids are contributed by two primary sources: chakka solids and added sugar (sucrose, which is considered to be 100% solids):
\[ \text{Total Solids} = \text{Chakka Solids} + \text{Sugar Solids} \]

Step 2: Detailed Explanation:
Let us calculate the amount of sugar required for the batch:
- Desired weight of final Shrikhand = 1 kg = 1000 g
- Minimum total solids required under FSSAI regulations = 580 g
- Solids contributed by the chakka ingredient = 180 g
Using the mass balance for total solids:
\[ \text{Sugar Solids Required} = \text{Total Solids Required} - \text{Chakka Solids} \]
Substitute the values:
\[ \text{Sugar Solids Required} = 580\text{ g} - 180\text{ g} = 400\text{ g} \]
Since commercial sugar is dry and behaves as 100% solids, adding 400 g of sugar will contribute exactly 400 g of solids to the mixture.
This addition brings the final total solids level of the 1 kg batch to exactly 580 g (58.0%), satisfying the regulatory standard.

Step 3: Final Answer:
The amount of sugar that must be added to comply with FSSAI regulations is 400 g.
