Pine nuts are threshed from pinecones, which are pinecones. This is the first step of pine nut processing and cannot be adulterated. If you don't trust, you can buy this kind of raw pine nuts in the market. Just go home and heat it in the microwave.

Adulteration is in the process of frying, adding one kind of white flour, the other is yellow, and there must be preservatives, which prolongs the storage time. We can't say that both the super-good-looking ones sold in the market and those in Huang Chengcheng have problems. We can only say that if we buy them carefully, the good-looking ones are not necessarily good, and everyone can choose the ones that are not good-looking. Another most important trick is pure speculation. The openings are uneven, and the openings are all the same, but there will be problems.
