Summer is coming, and the season of watermelons is on the market. However, the price of watermelons on the market is limited. How can we tell the economic value of watermelons to the maximum? We may wish to learn about the deep processing technology of watermelon, so that the derivative products of watermelon bring us more economic benefits.
1. Watermelon beverage processing technology
Watermelon drink, we are all familiar with watermelon juice, here we introduce the processing technology of watermelon juice.
Select the freshly harvested eight ripe red peony watermelon, wash the epidermis, cut the peeled and seed, then place the squash in a clean cloth bag, press the juice with a press and filter through double gauze, and filter the juice with white. The sugar is adjusted to a sugar content of 12%, and then adjusted to an acidity of 0.3%-0.5% with citric acid. After heating to 70 degrees, it is filtered by a plate and frame filter, and then heated to boiling, taking 0.2% to 0.5% of the total amount of the original juice. Agar or xanthan gum (as a thickener to prevent precipitation), dissolved in hot water, poured into the original juice, and placed in a washed and sterilized beverage bottle. After sealing, it is sterilized in boiling water of 100 degrees for 10 minutes, and then placed in hot water of 80 degrees, 60 degrees and 40 degrees, respectively, for 10 minutes, and then taken out, which is a watermelon with uniform appearance, bright color and delicious flavor. Original juice drink.
2, watermelon steam processing technology
In the summer, ice watermelons are loved by everyone. If you make watermelons into ice-cold and cool soda, will it be more marketable?
The processing technology of watermelon soda, use watermelon to squeeze juice, add the same amount of white sugar, then pour it into a stainless steel sandwich pot and heat to boil. Subsequently, according to the general method of processing soda, it is noted that the amount of the original liquid accounts for 10% of the total amount of steam, that is, the 250 ml soda bottle should be added with 25 ml of the original liquid.
3, watermelon crystal processing technology
Watermelon crystals have a long shelf life and a better taste.
After pressing the melon juice, inject it into a thin film evaporator or other concentration tank, concentrate to a soluble solid content of about 30% (measured by a sugar meter), crush the white sugar to a 100 mesh sieve, and then concentrate the concentrated watermelon juice with The sugar is mixed at 1:10, and then added with a small amount of citric acid to form a dough, then placed in an oven, dried at 50-60 degrees for 20-30 minutes, and finally sieved and sealed in half.
4, watermelon canning processing technology
The watermelon itself is sweet, cool and delicious. It can be processed into Canned Food, which is also the best in Canned Fruit. It has color, aroma and taste.
Use watermelon with less flesh red and high content, wash and peel off the seeds, cut the melons into strips, and then soak them in 5% calcium bicarbonate solution for 15 minutes to harden them. 50 kg of water and 12.5 kg of white sugar were placed in a sandwich pot and boiled to dissolve, then filtered with 8 layers of gauze, then 0.1% calcium chloride and 0.15% citric acid, followed by hardened melon Wash the clams with water, drain them, put them into a sterilized can, and finally inject more than 80 degrees of candy liquid, vent for 5-10 minutes, and then turn into watermelon cans after cooling.
Here we will introduce four kinds of watermelon deep processing technology, hope to help you to continuously improve the economic value of watermelon in the sales of watermelon, and bring more economic benefits to everyone.
Rice protein is a kind of complete protein, and rice protein peptide contains 18 kinds of essential amino acids. The absorption rate of rice protein peptide in human body is more than 98%, it can improve the immune function of human body, anti-fatigue, is conducive to the growth and development of children, especially can promote the intellectual development of children.
At the same time, the valley sterol contained in rice protein, can inhibit the role of cholesterol, the high content of cholesterol in the human body can play a role in regulation and balance.
