Answer

Yes, in Jain food practice, green chilli can be used if it is not spoiled, fermented, or infested.

If by “not fresh” you mean:

• Slightly old but still good — generally acceptable.
• Dried green chilli — generally acceptable.
• Rotten, moldy, smelly, or fermented — should not be used.

Explanation

In Jain Dharma, care is taken to avoid food that contains or encourages excessive living organisms. Old or spoiled food may develop many microorganisms, so it is avoided.

So before using green chilli, check:

• No mold
• No bad smell
• No sliminess
• No insects or worms inside
• Not fermented or rotten

Takeaway

If the green chilli is only a little old or dried but clean and usable, it may be used. If it is spoiled or decaying, avoid it as per Jain food discipline.
