Answer

In Jain Dharma, soyabean chunks are generally considered allowed to eat, because soybean is a type of bean/legume and is not a root vegetable.

Explanation

However, you should check a few things:

• Ingredients: Plain soya chunks are usually made from soy flour. Avoid if they contain onion, garlic, eggs, meat flavoring, or non-vegetarian additives.
• Freshness: Do not eat if spoiled, fermented improperly, or infested.
• Preparation: Cook and consume in a clean, Jain-friendly way, avoiding onion, garlic, potatoes, etc., if you follow strict Jain food rules.
• Personal vows: Some people follow stricter family, sampraday, or guru-guided rules. In that case, follow your vow or ask your guru.

Takeaway

Plain soyabean chunks are generally Jain-permissible, but they should be vegetarian, free from prohibited ingredients, and prepared according to Jain dietary discipline.
