1. Do not eat sprouted purple potatoes.

2. Sprouted purple sweet potatoes contain toxins, which can cause the purple sweet potatoes to rot and damage people’s health. When purple sweet potatoes sprout, starch and sugar will be degraded into nutrients needed for germination. During the degradation process, purple sweet potatoes will release some toxins, causing purple sweet potatoes to easily become moldy and rotten (due to the decomposition of starch, the water content increases and they are easy to spoil). Soft and tastes bad.

3. Fresh purple potatoes are not only delicious, but also very nutritious. However, if you buy too much and put it at home, it will often sprout soon. To make the purple sweet potato last longer without sprouting, just put the purchased purple sweet potato in the sun for half a day and then put it in a dry place. The purple sweet potato will not sprout and will increase the sweetness.
