How to keep cherry fresh for the longest time
Preparation of preservative
Preservative solution is a kind of acid sugar solution with appropriate preservatives. Sucrose, grape candy or fructose can be used as sugar, and its concentration is appropriate when the osmotic pressure of the solution is balanced with that of the cherry. In this way, cherry can avoid swelling, cracking or shrinkage deformation, and maintain its original texture. The average sugar content of cherry is 12% to 16%, and the sugar concentration of preservation solution is 15% to 20%. Acid can be citric acid or edible phosphoric acid, that is to consider the inhibition of microbial growth, but also to prevent cherry bad sour. In general, the pH value of the solution should be 3.0 to 3.5. Sodium benzoate is used as preservative, or sodium benzoate and sodium sorbate are used at the same time, the dosage is not more than 0.1%. In order to improve the hardness of cherry, a small amount of calcium phosphate or propionic acid can be added.
soak
Rinse the cherry with clean water, drain and put it into the freshness preservation solution prepared in advance. The amount of cherry added is about 60% of the weight of the freshness preservation solution. It can be sweetened after 1 to 4 months storage under natural conditions.
Sweetening processing
Remove and drain the cherry from the preservative. Heat and concentrate the preservative solution until the sugar concentration reaches 28%. Soak the cherry in it for 1 day and take it out. After repeated 2 to 3 times, the sugar concentration of the preservative solution was about 38%. The cherry processed by this method has good aroma and taste. In addition, after removing the stem and core of the cherry, it can be soaked in the concentrated fresh-keeping solution. After repeated 2 to 3 times, the sugar content of the preservative solution reached about 45%.
Who should not eat cherry
1. Vitiligo patients should eat less cherry.
2. Those with ulcer symptoms, those with fire, should be careful to eat; those with diabetes should not eat.
3. The high potassium content of cherry is not to be taken lightly. It contains 258 mg of potassium per 100 g, which is not a small number for patients with kidney disease. In patients with kidney disease, if the function of regulating water and electrolytes is lost, the patient will have oliguria and edema. When oliguria occurs, potassium depletion is caused by potassium depletion. If patients eat too many large cherries, they will suffer * hyperkalemia. When blood potassium & gt; is 6.5 mmol / L, it can cause the patient's heart to stop beating in seconds to minutes. Therefore, hyperkalemia can be said to be the 'invisible killer' of chronic kidney disease.
