Blueberry contains rich anthocyanins and has good antioxidant power. It can prevent dementia in the elderly, protect cardiovascular and visual degeneration. It is a fruit with very high nutritional value. Refer to the previous article, blueberry anthocyanins have strong antioxidant power, protect the brain from dementia, prevent the three highs, protect the eyes and brain health, and is a blue stone in the forest. However, when buying blueberries, I often see a layer of smooth white powder on the surface of the blueberries. People often suspect that it is an agricultural medicine or something that is not clean, and some people even worry that it is a person who deliberately rinses it. Therefore, many people work very hard to wash blueberries, and use slurry, vinegar, and even cleaners to wash it hard. You must wash the white powder off to rest assured. Is this true?
The answer is wrong. This layer of white powder is a natural protective basin on the surface of blueberries. It does not need to be washed off and is natural and harmless. It is not necessary to over-clean blueberries and will reduce the nutritional value of blueberries. Just wash the blueberries with flowing water several times. Use small sour beans and vinegar to make them more abundant, and may cause the reverse effect of dyeing blueberries.
?The white powder on the surface of blueberries is also called bloom, which is a natural plant abortion of blueberries. The main ingredients are some triterpenes (such as ursolic acid) or diketones and esters, as well as some long-link fatty acids.
What is the use of the basil on the surface of blueberry?The baptis on the surface of blueberries forms a protective layer that can protect the damage of external bacteria, bacteria or vegetation to the blueberries, and can also reduce the loss of moisture inside the blueberries through the epidermis. Therefore, the basil quality of blueberries can be used as an indicator of freshness. The fresher the blueberries have more basil quality, the more the color it is. As the blueberry grows older, the quality of the worm will decrease, so the color will appear to be darker.
How to choose blueberry?The blueberry picks are full of grains, and the appearance is not damaged or deformed. The fresher the blueberry has more basil quality and the more color it is. However, the thickness of different varieties of blueberry berry jelly is different and cannot be compared with each other.
How to clean blueberries?Blueberries can be washed first with flowing water or soaked for a short time to remove foul- , dust or agricultural medicine. Blueberries that have been damaged may have bacterial or bacteria infections that are invisible to the naked eye, and should be abandoned in a whole. When cleaning blueberries, there is no need to use beans, vinegar, or cleaners, it is best to use water.
