Question

Which of the following starter culture is used for preparing Bioghurt

• A. S. thermophilus & L.acidophilus
• B. S. thermophilus & B.bifidum & L.bulgaricus
• C. S. thermophilus & L.acidophilus & B.bifidum
• D. S. thermophilus & B.bifidum

Hint:

To distinguish between related probiotic cultures:
- Bioghurt = S. thermophilus + L. acidophilus (No Bifidobacterium).
- Biogarde = S. thermophilus + L. acidophilus + B. bifidum.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Cultured milk products are formulated with specific combinations of starter cultures to optimize acid development, flavor profile, and probiotic delivery.
Certain specialty fermented milks utilize specific bacterial species to produce L(+)-lactic acid, which is more easily metabolized by the human body compared to D(-)-lactic acid.
Detailed Explanation:
Bioghurt is a specialty fermented milk product developed in Germany.
It is produced using a starter culture containing Streptococcus thermophilus and Lactobacillus acidophilus.
- Conventional yoghurt contains Lactobacillus delbrueckii subsp. bulgaricus, which produces a high proportion of D(-)-lactic acid.
- Bioghurt instead utilizes L. acidophilus, which is a probiotic organism that produces L(+)-lactic acid.
- This makes Bioghurt highly digestible and beneficial for gastrointestinal health.
Let us review other similar probiotic products:
- Biogarde: manufactured using a combination of S. thermophilus, L. acidophilus, and Bifidobacterium bifidum.
- Biokys: manufactured using L. acidophilus, B. bifidum, and Pediococcus acidilactici.
Therefore, the starter culture used to prepare Bioghurt contains S. thermophilus and L. acidophilus.
Final Answer:
The starter culture used for preparing Bioghurt is S. thermophilus and L. acidophilus. Hence, the correct option is (A).
