Can you eat zucchini skin?
Zucchinis are waxed to extend their shelf life. Grocery stores and supermarkets that don’t buy local produce often obtain waxed zucchini and squash to keep the produce fresh. Zucchinis that are bought local often aren’t waxed. To determine if zucchini skin has been waxed, run a finger over the skin and feel for a waxy coating. Source: startcooking.com
