Short answer: No. In Jainism, wasting food goes against the principles of ahimsa (non-violence) and aparigraha (non-attachment/renunciation), and it harms living beings that may have eaten the crop or depended on that food.

Why it’s discouraged:

• Ahimsa: Wasting food can involve harm or waste of life that contributed to that meal (plants or microorganisms), which is contrary to non-violence.
• Karma: Carelessness with food can generate negative karma; sharing and conserving resources helps purify conduct.
• Simplicity and restraint: Jain ethics emphasize living with restraint, gratitude, and mindful consumption rather than excess.

Practical guidance:

• Plan portions to avoid leftovers.
• Use leftovers creatively or donate surplus to those in need.
• Buy only what you will realistically use; store and use food mindfully.
• Respect harvests and farmers by reducing waste.

Note: There are no major doctrinal rifts here between Digambar and Shwetambar on the core stance against food waste; both traditions emphasize non-violence and simple living.
