Answer

Yes, in common practice, the 11th day after Dashlakshan is observed as Kshamavani or Kshamapana Divas, especially in the Digambar Jain tradition.

Regarding food items that were paused during Dashlakshan: generally, after Dashlakshan is completed, one may resume those items from the next day, unless one has taken a specific vow to continue longer.

Explanation

Dashlakshan Parva is traditionally observed for 10 days, focusing on the ten supreme virtues:

• Uttam Kshama
• Uttam Mardav
• Uttam Arjav
• Uttam Shauch
• Uttam Satya
• Uttam Sanyam
• Uttam Tap
• Uttam Tyag
• Uttam Akinchanya
• Uttam Brahmacharya

After these 10 days, the following day is commonly observed as Kshamavani, when Jains seek forgiveness from all living beings and say:

Michhami Dukkadam / Uttam Kshama / Khamemi Savva Jive, according to tradition and language.

If you had paused certain foods as a personal niyam for Dashlakshan only, then it is generally considered completed after the 10 days. So from the 11th day, you may resume them.

Spiritual Understanding

However, if you had taken a vow in front of Guru, temple, or with a fixed longer duration, then you should follow that vow exactly. In Jain Dharma, the purity of intention and honesty in observing a niyam are very important.

Takeaway

If your food restriction was only for the 10 days of Dashlakshan, then yes, you may eat those items from Kshamavani day, the 11th day. If it was a longer vow, follow the vow as taken.
