How to make canned blueberries

The canned fruits that we often eat in our daily lives are generally made from yellow peaches. Because yellow peaches are rich in sugars, canned fruits made from yellow peaches will be sweeter. But in addition to yellow peaches, you can also use fruits such as grapes and blueberries to make canned fruits. Canned blueberries are also a popular snack for everyone. What are the methods for making canned blueberries at home?

Ingredients for canning blueberries:

Main ingredients: fresh blueberries, rock sugar water (dissolve the rock sugar in boiling water and cool it down before use according to your taste)

Steps for canning blueberries:

1. Boil the canned bottles in water in advance to sterilize them.

2. Wash the blueberries and put them into canning jars, filling them only 70% full!

3. Pour the pre-melted rock sugar water into the bottle with blueberries. Just fill it 70% full!

4. Put the bottle of blueberries into the pot and steam it. The size of the container varies. Steam until the color of the rock sugar water in the container becomes darker. Do not steam it for too long!

5. After turning off the heat, tighten the bottle cap immediately (be sure to wear gloves to prevent burns) and place it upside down until the bottle is completely cool! After cooling, check whether the bottle cap is tightly sealed. If not, put it directly into the refrigerator and consume it within 20 days. If it is tightly sealed, it can be stored at room temperature for more than 1 year!

The efficacy and function of blueberries

1. Protect your eyesight

Studies have found that eating blueberries can reduce the risk of age-related macular degeneration by 38%.

2. Prevent and treat constipation

One cup of fresh blueberries contains about 4 grams of dietary fiber, which accounts for 14% of the daily dietary fiber intake. The water-soluble dietary fiber in blueberries can promote intestinal motility and prevent constipation.

3. Enhance immunity

Studies have found that blueberries contain far more antioxidants than other fresh vegetables and fruits. Antioxidants neutralize free radicals in the body and boost the immune system.

4. Reduce belly fat

The polyphenols in blueberries can break down abdominal fat and help control weight. In addition, blueberries are low in calories and will not cause weight gain.

5. Improve brain power

Snacking on dried blueberries can boost brain power. A new study finds that flavonoids, found in blueberries, may help alleviate age-related memory loss.

6. Good for Heart Health

Blueberries contain ingredients that can help dilate blood vessels, thereby reducing the risk of blood clots and heart disease. Studies have found that eating more than five servings of blueberries a week can reduce the risk of heart disease.

7. Lowers blood sugar

Eating blueberries can help regulate blood sugar levels in people with diabetes. Eating five servings of low-glycemic-index fruits such as blueberries per week for two months can significantly improve blood sugar regulation.

8. Strengthen Bones

Blueberries are rich in the trace element manganese, which plays a key role in bone development. Studies have found that children who like to eat blueberries have higher bone density than children who do not eat blueberries.

9. Prevent Cancer

Anthocyanins in blueberries can inhibit the growth of tumor cells, and eating half a cup a day can achieve anti-cancer effects.

10. Prevent cystitis

Some ingredients in blueberries can prevent bacteria from adhering to the bladder wall, preventing cystitis and urinary tract infections. Studies have found that eating a handful of blueberries a day can help improve urinary tract infections.
