Some fruit stall owners say that they want to buy mother grapefruit. It is sweeter. Will Grapefruit be relatively astringent?Is grapefruit still divided up and mother?In fact, grapefruit is not divided into mother -in -law. Some merchants are mainly distinguished by the "small circle" at the top or bottom of the grapefruit.However, these "small circles" are just the scars left by the fruit or Xie Hua, which is not directly related to whether grapefruit, sweet and not sweet.When buying grapefruit, if you pursue nutritional value, red -hearted grapefruit and white heart grapefruit have their own nutrition; if they pursue the taste, red heart grapefruit will be better than white heart grapefruit.

The neck should not be too long. If it is too long, it represents more skin and less meat."Lower width" is to require grapefruit "short, fat, round", and the bottom should be full.
Third, look at the size.Generally speaking, the larger grapefruit has a higher maturity and more flesh.
Fourth, pinch.Good grapefruit pinching up is hard, making people feel strong, representing the tightness of the flesh and more juice.If there is no elasticity and softness, it means that it may be placed for a period of time, and the water loss is more serious.
Fifth, weight.If two grapefruit of the same size can be placed on the left and right hands, the heavier water is more sufficient.
In addition, grapefruit belongs to the family.Because grapefruit skin is rich in essential oils, rubbing and smelling it does have the effect of refreshing, and it can also cover some odors, but there is no scientific basis to remove formaldehyde.
