Question

The amount of salt required in the preparation of sauerkraut is:

• A. 2-3%
• B. 0.5-1%
• C. 5-6%
• D. 4-6%

Hint:

For perfect Sauerkraut, the weight of salt should be exactly 2.25% of the weight of the shredded cabbage. This ensures the correct sequence of LAB (L. mesenteroides followed by L. plantarum).

Answer 1

The Correct Option is A

Making sauerkraut relies on shredded cabbage undergoing natural lactic acid fermentation, and salt plays a balancing role in this. Too little salt, below about 2 percent, leaves the cabbage soft and prone to spoilage, while too much salt, above roughly 3 percent, ends up suppressing the very lactic acid bacteria that are supposed to ferment it. The commercial sweet spot sits right in between, so the salt concentration used is about 2 to 3 percent.
