Answer

In Jain practice during Paryushan, it is generally best to avoid dry tomato powder.

Explanation

Tomato itself is usually considered a vegetable/fruit used in food, but during Paryushan many Jains follow stricter food discipline and avoid items that may involve:

• Stored or processed ingredients
• Powders whose preparation method is not clearly known
• Possible fermentation, preservatives, additives, or contamination
• Difficulty in knowing whether it was prepared according to Jain food rules

Dry tomato powder is a processed and stored food item, so many Jain families and sanghs would not use it during Paryushan.

Spiritual Understanding

Paryushan is a time for greater simplicity, restraint, and purity in food and conduct. Even when something may seem technically acceptable, many devotees avoid doubtful or processed items to maintain stricter awareness and discipline.

Takeaway

If you are observing Paryushan strictly, do not use dry tomato powder. If your family or guru follows a specific maryada, it is best to follow that guidance.
