Answer

Yes, you may eat packed food like banana/Kela wafers only if you are sure it is fully Jain and it follows your personal Jain rules.

Explanation

In Jain Dharma, the main points to check are:

• Ingredients: No onion, garlic, potato, root vegetables, eggs, meat, fish, honey, alcohol, or non-Jain additives.
• Oil and flavoring: Sometimes wafers contain spices, flavor enhancers, or seasonings that may not be Jain.
• Manufacturing: Even if ingredients are Jain, some people avoid food made in factories where non-Jain items are also processed.
• Freshness: Many Jains avoid stale or old food. Packed food may be days or months old, so stricter followers may avoid it.
• After sunset: If you follow the rule of not eating after sunset, then packed food should also not be eaten after sunset.

Spiritual Understanding

Jain food discipline is not only about ingredients. It is also about reducing harm, being careful, and keeping purity in food habits. So if Kela wafers are truly Jain, fresh according to your practice, and eaten mindfully, they may be acceptable.

Takeaway

If you are 100% sure the Kela wafer is Jain and it matches the rules followed in your family or sampraday, then you can eat it. If there is doubt, it is better to avoid it or ask your guru, elder, or knowledgeable Jain person.
