1, the concept: the shell is slightly red, red with brown, purple, enamel and other colors, uniform and shiny particles, the quality is generally better. If it is dark, it indicates that the fruit has been worm-eaten or has been deteriorating by heat.
2, fruit: pinch the chestnuts by hand, feeling solid particles, generally full flesh; such as pinching the sense of empty shell, it shows that the flesh has dried up, or was sultry hot meat has been soft.
3. Hand crank: Put a chestnut shake on the table, or shake it into your hands. If you make a shell sound, the flesh will be hard and dry. It will be the chestnuts of the next year or the fresh chestnuts posing as fresh chestnuts.
4, tasting: good chestnut nuts yellow, strong, fine meat, less water, high sweetness, enamel quality, strong flavor, eat the United States; the other hand, the hard and odorless, eat poorly.
Good chestnut good mood, good life!
