What s going on with blueberries being sour, what to do with blueberries being sour

Blueberries in Japan and blueberries in Xinjiang are the most famous, because the blueberries produced in these places taste sweet, and the blueberries produced in other regions taste sour, which has a certain relationship with the growth environment of blueberries, blueberries are very high requirements for the environment, especially the pH value of the soil, so what should I do if blueberries are too sour?

Blueberry fruit has high nutritional value and health care effect, and its cultivation and production have developed rapidly in China in recent years. Guoshan area accounts for 69% of the country's land area, mostly acidic soil, with a wide range of localized germplasm resources and cultivation and planting conditions, and has unique advantages in the development of blueberry industry.

However, blueberry cultivation has very strict requirements for soil pH, except for the Daxing'an Mountains and Changbai Mountain areas, the soil in other areas must be specially improved before blueberry cultivation, and unsuitable soil conditions often lead to poor growth and even death of blueberries.

Therefore, the scientific and reasonable soil improvement method of blueberry cultivation is very important, which requires thousands of experimental studies to analyze and summarize the improvement methods to promote the normal growth of blueberry.

1. Suitable pH

1. Requirements for soil pH value of blueberries.

Blueberry has high sensitivity to soil pH, and the requirements for soil pH value are very strict, only when the soil pH value is adjusted to a suitable range, it is conducive to the good growth of blueberry, once the soil pH value exceeds the suitable range, it is easy to cause poor growth of blueberry, lack of mineral elements, and decline in fruit quality.

Blueberry growth requires strong acidic soil conditions, and the soil is the most suitable range. Under normal circumstances, the northern highbush blueberry requires the pH of the soil to be around the right, and the rabbit's eye blueberry requires the pH value to be around the right and left for the best growth.

2. What is the effect of unreasonable pH value on blueberries?

Effects of a high pH:

It caused the lack of FE and the loss of green, the quality of single fruit decreased, and the yield decreased to promote plant death.

When the pH value in the soil is too high, the contents of Fe, Mn and annual L in the leaves are reduced, and at the same time, blueberry is also a calcium-disgusting plant, which is sensitive to excessive calcium, and the solubility of calcium increases when the soil pH increases, and the plant absorbs excessive calcium, causing calcium toxicity. When the soil pH value is too high and the calcium content is too high, the iron ions in the soil combine with the organic matter to form a complex that cannot be absorbed, inducing iron deficiency and chlorophilia.

Ammonium nitrogen in the environment is converted into nitrate nitrogen under the action of microorganisms, which is not easy to be absorbed by blueberries and is prone to nitrogen deficiency in plants.

The availability of other mineral elements and ions such as MN, CU, ZN, etc. in the soil also decreases with the increase of pH, resulting in hypoxia, stunted growth, and leaf greening.

The growth and yield of blueberry plants gradually decreased with the increase of soil pH, and when the soil pH was greater, the growth of blueberry would be stunted, the leaves would lose green, the fruit would be poor, and even lead to the death of the tree in severe cases.

Blueberries are as high in nutritional value as sweet and sour.

Nutritional value of blueberries:

Blueberry fruit contains sugar, acid and vitamin C in addition to the regular amount

In addition, it is rich in vitamin E

Vitamin A, vitamin B

Superoxide dismutase (SOD), arbutin, protein, anthocyanins, edible fiber and rich in potassium, iron, zinc, calcium and other mineral elements, vitamins are higher than other fruits, trace elements are also very high, high amino acids, high copper, high zinc, high iron fruits.

In addition, blueberries contain a lot of anthocyanins.

And the efficacy of anthocyanins is very rich, as follows:

1.Prevent disease.

Anthocyanins can scavenge harmful free radicals in the body, which are one of the important causes of aging and many diseases, and it is estimated that about 80%-90% of aging and degenerative diseases are related to free radicals, including cancer.

Alzheimer's disease, Parkinson's disease.

**Dark spot deposition, cataract.

Heart disease and so on. Therefore, the elimination of harmful free radicals is essential to keep the body healthy and young.

2.Improves eyesight.

Clinical studies have shown that the anthocyanins in blueberries can promote the regeneration of rhodopsin in retinal cells, prevent severe myopia and retinal detachment, and improve vision.

3.Hairdressing. Anthocyanins in Europe, known as "oral **cosmetics", can prevent the premature formation of **wrinkles**, in addition, anthocyanins are also natural sun coverers, can prevent ultraviolet damage**.

4.Improves sleep.

Anthocyanins have the effect of penetrating deep into cells to protect cell membranes from being oxidized by free radicals, have strong antioxidant and anti-allergic functions, can cross the blood-brain barrier, can protect cranial nerves from oxidation, can stabilize brain tissue function, and protect the brain from harmful chemicals and toxins, thereby completely improving sleep quality.

5.Strengthens blood vessels and improves circulation.

Blueberry jam. Ingredients: 500 grams of blueberries, 250 grams of rock sugar.

Method: 1. Clean the blueberries with water, and pay attention not to rub them vigorously and not to break the skin;

2. Put the blueberries and rock sugar together in a pot, turn on low heat and stir slowly to let the rock sugar slowly boil;

3. Cook slowly over low heat, skim off the foam in the middle, boil until the jam is viscous to the coagulation point, seal it in a clean container and eat, and put it in the refrigerator to preserve the taste better.

1. Blueberries are sweet and sour, beautiful and anti-cancer.

Blueberry pulp is delicate, the flavor is unique, the sweet and sour is moderate, and it has a refreshing and pleasant aroma, therefore, many people like the taste of blueberries very much, and often use blueberries as yogurt, biscuits, bread, etc. The color of blueberries determines that it contains a large amount of anthocyanins, and anthocyanins are very important plant water-soluble pigments, which are pure natural anti-aging nutritional supplements, and are the most effective antioxidant bioactive agents found by human beings. The anthocyanin content in blueberries is very high, and the anthocyanin species are also very rich, and the study found that the anthocyanins contained in the highbush blueberry fruit are as high as 15 kinds, although the anthocyanin content in different varieties of blueberries is not the same, but the general content is relatively high.

That's why blueberries are an anti-aging product.

The organic acids contained in blueberries are a powerful tool for blueberries as a small anti-cancer expert. The organic acid content in blueberries accounts for more than half of the total acid content. Most of the organic acids are citric acid, and the others are ursolic acid, quinic acid, and malic acid.

It should be emphasized that ursolic acid, also known as ursolic acid, belongs to a weakly acidic pentacyclic triterpenoid, which is a functional component of a variety of natural products, with a wide range of biological activities, especially in anti-tumor and other aspects.

Second, choose blueberries, it is better to have white fog.

The average weight of blueberry fruit is 5g, so natural blueberries are not very large, and it is important to be careful when choosing not to be the bigger the blueberry, the better. Pick the fruit to choose plump and round, uniform size, firm, firm fruit, firm and full, smooth skin, dry to the touch, usually without leaves and stems. The fruit is dark blue-purple with a white mist, and the skin color is a sign of whether the blueberry fruit is ripe, and the fruit of a ripe blueberry should be between dark purple and blue-black.

Red blueberries are often not ripe, but they can be used in dishes. Blueberries can be stored in the refrigerator, but the container must be dry. Store unwashed blueberries in a hard container with a lid to avoid bumps and mold.

Fresh blueberries should be placed in the refrigerator and washed before serving. It is best to consume fresh blueberries within 10 days after purchase.

Blueberries were first popular abroad, and were often seen on the shelves as fruits in China, but it was not common to cultivate them as a family fruit tree. In recent years, with the increasing popularity of blueberries, many of our flower friends have begun to grow their own blueberry trees, and many of them have accumulated deep experience

About the amount of sunlight required for blueberries.

Blueberries are also slightly shade-tolerant, and generally speaking, blueberries can get full sunlight, unless the sun is really strong in summer, so they need proper shade. Therefore, if the sun is not good at home, it is not recommended to plant blueberries, because if you plant them, even if the fruit grows, the taste will not be very good.

About how to fertilize blueberries.

Blueberries are not a fertilizer-loving plant, but that doesn't mean they don't need fertilizer.

Before the blueberries are planted, I generally put down the bottom fertilizer, you can choose to use earthworm manure, rotten pigeon manure or chicken manure, the amount does not need to be much, put a good bottom fertilizer, and then cover the soil to ensure that the blueberry root system is more than 15 cm away from the bottom fertilizer, so that the roots find fertilizer, do not let the fertilizer find the roots.

Before germination in spring, when there are no leaves, I need to water liquid fertilizer once, and I mainly use liquid fertilizer or enzyme dilution in the compost box. Compost bin liquid manure and water 1:100 irrigation roots, 1:

200 spray branches. Enzymes and water are 1:50 irrigated roots, 1:

100 spray shoots.

After waiting for flowering, I won't fertilize. After the results, I will continue to water the liquid fertilizer mentioned above. Then the blueberry pot will be spread on the surface of the blueberry pot with a thickness of about 2 mm of earthworm manure or rotten pigeon manure, and there is no need to fertilize it in the future, the blueberry does not have high requirements for fertilizer, too high will hurt it, so that it is enough to give birth to high-quality blueberries.

Blueberries may not be ripe if they are too sour. Unripe blueberries have a similar taste to wheat grass and have a sour taste. Ripe blueberries are blue or dark purple in color, have a layer of hoarfrost on the surface, have a sweet taste, and have a certain sour taste, depending on the individual situation, so what to do with blueberry sour?

If the blueberries are sour, it may be due to not being ripe. At this time, it is better to put the blueberries in the ripe fruit so that the blueberries can ripen.

In addition to ripe fruits, ripening agents can also be used to ripen blueberries. It's also a good idea that ripe blueberries are usually not sour.

You can also soak blueberries in brine for a while, so that they are not so sour, and they can also play a bactericidal role, but it should be noted that there is not too much salt in the brine water.

You can also soak the blueberries in rock sugar water so that the blueberries are not so sour and will be a little sweet. It's also a good idea.

After the blueberries are processed by the above methods, they will become soft and need to be eaten in time, otherwise, the taste of blueberries will not be good.

Finally, if the blueberries are sour, they can be left for a while to ripen naturally, and the taste will be better, but they will become softer.

First of all, look at the color of the blueberry, there is a layer of white fruit cream on the surface of the blueberry, which determines the freshness of the blueberry. The darker the surface of the blueberry, the better, to remove the fruit cream. The color of the skin is dark red, that is, it is not fully ripe, and you are not in a hurry to eat, you can buy it and put it on the upper layer of the refrigerator for a period of time.

The second is to look at the size of the blueberry, the small blueberry variety will be sweeter, and the coin-sized one will be more sour.

What should I do if I am worried that I will eat sour food after I buy it? Teach you a trick and it will definitely work!

Rinse the blueberries with cold water first, rinse them with hot water, soak them in hot water, and the darkening of the blueberries means that the blueberries are sweet, and the red ones are sour, and there is no discoloration, so find a way to pick them out and eat them directly.

Then, it is to look at the fruit pedicle of blueberries, blueberry rot and deterioration all start from this part, generally buy blueberries in the supermarket, are boxed, after picking up the box, carefully observe the bottom of the box, whether there is blue juice liquid flowing out, if you find it, it means that there are already blueberries ripe and begin to rot.

Finally, touch the blueberries. Due to light, some blueberries evaporate and can easily dry up and soften, and this kind of blueberry will taste very sour.

If it is plump and firm to the touch, such a blueberry is not guaranteed to be sweet, but at least it must be a blueberry of better quality and can be bought at home.

Smell Fresh blueberries smell more refreshing, which is the aroma of the blueberries themselves. If the blueberries are left for too long, they will emit a faint sour smell, which is not recommended for everyone to buy.

Look at the color Freshly ripe blueberries are generally dark purple, and if the blueberries look red, they are definitely not ripe and have a sour taste.

Touch the appearance When choosing blueberries, you must touch the peel, generally fresh blueberry peels are relatively smooth, if the peel is wrinkled, it means that such blueberries have been placed for too long, and the moisture inside is about to disappear. The texture and taste are greatly reduced, so don't buy it!

May time slow down, may the deceased not be separated, may the person you miss can say goodnight to you, and may you not feel lonely in the days of solitude.

Summary. It may be that the pH of the blueberry production area is too high.

Why are blueberries so sour?

It may be that the pH of the blueberry production area is too high.

Blueberries in Japan and Xinjiang are the most famous, because the blueberries produced in these places taste sweet, and the blueberries produced in other regions taste sour, which has a certain relationship with the growth environment of blueberries, and blueberries have very high requirements for the environment.

It could also be undercooked. Unripe blueberries taste similar to wheatgrass, with a sour and astringent taste that causes a bitter taste on the tongue when eaten in the mouth, while ripe blueberries have a dark purple or blue-black skin covered with hoarfrost.
