Why are raisins ten times more expensive than regular grapes? How are raisins made?

Raisins need to be specially treated, and then dried to evaporate all the water, which is why he is so sweet, and the production process requires a lot of grapes, so it is more expensive.

It may be that this raisin is artificially dried, so it takes a long time, while ordinary grapes are not needed. It is to filter and distill the grapes and then dry them.

Because raisins go through a lot of processes, they need to be juiced first, and then the seeds inside are removed, cooled, and then dried.

The harvester swings the springs on its head up and down, shaking the raisins off the tree and falling into the collection bucket under its jurisdiction. This is a vineyard in the beautiful country of California, because the unique climate and soil of the region are tailored for the growth of grapes, so the raisins produced here are ten times more expensive than the usual raisins**.

Clause. 1. Workers in the orchard plant the musts in the soil at the end of winter each year, and these musts take three years to grow and bear fruit. At the same time, the workers will also prune the adult vines, minus dead branches, to reduce the number of buds, so that the nutrients are concentrated in the remaining shoots, so that they can reach the larger and fuller fruit, and then the remaining shoots are wound around the wire frame and firmly fixed, and then the branches and leaves will grow into an arch along the wire frame, so that the light can be maximized.

When the grapes are ripe, the branches are cut and the bunches are hung on the vines to be dried.

Clause. Second, the process requires waiting six to eight weeks before the raisins are picked by this specialized harvester, and the workers send the raisins to the processing plant. Here, these raisins need to go through a rigorous selection.

Inspectors from the Ministry of Agriculture inspect raisins as they pass through the conveyor belt, removing defective bad fruit, checking the moisture content and the overall quality of the fruit. Then the vacuum machine sieves the branches, which are easier to remove because they are cleaner than raisins. The screened raisins are stored for several weeks before they can be processed.

During this period, the sugar in the raisins will ooze feces and stick together, and this roller machine in the mixing piece can break the clumps and remove the raisins, and some of the raisins still have roots, and this conical machine can remove the roots by turning them without harming the raisins.

Clause. 3. After the raisins are sorted by size, they will go through three cleaning procedures, and then the residual branches and defective fruits will be detected by laser agent, and finally they will go through a manual inspection. After passing the inspection, the raisins are ready to be packaged.

The packaging machine opens the passing boxes and places them on the conveyor bag with an opening up, and the raisins are loaded into multiple boxes in a split second, and the plant is very efficient, filling an average of 30,000 boxes of raisins per hour.

How grapes become raisins, how the water is removed, read the knowledge.

In fact, it is in a more suitable area. It is necessary to have a very suitable climate and dry the grapes in a cool place so that they can become raisins.

In Xinjiang, the grapes are generally hung in bunches on very high bamboo shelves, which can provide good ventilation and allow the grapes to absorb moisture.

Raisins are made of fresh grapes, fresh grapes are picked in bunches, dried in the sun for many days, lose moisture, form raisins, remove residues during processing, after cleaning and drying, further divided into different grades of products, packaged, and sold to the market.

Grapes are a kind of fruit that people like to eat, and many people like raisins, and the process of turning grapes into raisins is mainly dehydration, spreading the grapes and exposing them to the sun, so as to make raisins.

Raisins are made under strict conditions, so how are grapes made?

Clause. First, the workers spread the cleaned grape bottles on the grid-like shelves, and as the sun shines for longer and longer, the water in the grapes gradually evaporates, leaving only most of the sugar. It is a factory that specializes in making raisins, in which the raw material for making raisins is mainly from a type of grape called seedless white.

At the end of August, when the seedless white is ripe, workers will pick them with tools and transport them to a nearby dust shelter by truck.

Clause. Second, but before processing, workers will have washed and drained the grapes back into the concentration of about 2% vinegar drying agent water to soak for one minute, at this time the potassium carbonate in the vinegar drying agent can destroy the toughness and waxy layer of the grape skin, so that the grapes can greatly shorten the dehydration time at the same time, can also reduce the degree of chlorophyll oxidation in the raisins, to a large extent retain the original green of the grapes. Once the grapes have dried and dried, workers spread them on shelves with layers of grids.

However, the seemingly random laying method can be a good way to hang a whole bunch of grapes on the grid.

Clause. 3. Usually such a dust-proof shed can dry more than 1,000 catties of grapes, because these grapes need to be kept for a long time. Maintaining sun exposure also largely determines the rate of raisin production in an area.

Usually after 15 days, the grapes have less than 15% moisture and a little frosting, at which point the workers will recollect them and remove the cakes by machine, so that the raisins are basically processed. To keep the raisins dry during storage, workers put them together in a factory that is always ventilated, and when people or other factories need it, they can be sent to where they are needed. At this point, the processing of raisins is completely finished.

Drying at high temperatures, in such an environment, can make the grapes dry quickly, and the taste is also great.

First, the grapes are picked and hung in the drying room, and then they are left to dry.

First, the grapes of the right size are selected, then they are hung on the shelves one by one and sent to the drying room.

In fact, the method of making raisins is very simple, but it takes a long time, because when making raisins, you first need to remove the grape skin, take out the grape seeds, and then put them in a sunny place for exposure, and after drying the water in the grapes, the raisins will be completed by themselves; Raisins are relatively sweet, so you shouldn't eat too much every day, you can add a few grains to some desserts or soups to increase the taste, and they won't be too sweet.

It is usually produced in Xinjiang, with that kind of large grapes, and then dried directly, because the fresh climate environment is very good. I think it's okay to add it when cooking.

First of all, it is necessary to select the right raw materials, subtract the damaged fruit after harvesting, then soak it in alkaline water for treatment, and then expose it to the sun for about 10 days, and you can do it; It can be soaked in water with red dates and wolfberries, and can be eaten directly, or you can put a few raisins on steamed buns or fat cakes.

Fresh grapes have been made into sweet and sour raisins for thousands of years, but the variety of varieties and the different climates vary from place to place.

Clause. 1. Seedless white grapes with plump flesh and high sugar content are the preferred raw materials for making raisins. In order to reduce labor costs, farmers cut the texture of the vines directly when the grapes are ripe, so that they can be allowed to dry naturally for 60 days in a dry climate, until all the grapes are completely dehydrated, and then the raisins can be pulled off the branches with this special harvesting equipment, and then the harvester can be used to concentrate on the harvester and then proceed to the next step of processing.

In areas that are not suitable for natural air drying, the cost and process of production are much more cumbersome than the former.

Clause. 2. Farmers need to remove the rotten fruits with small particles or cracks when cutting the bunches again, and then sort the large bunches of grapes into small bunches suitable for drying, and then send them to a special drying field for the first inspection process. This cloudy white liquid is a mixture of sodium hydroxide and sodium carbonate, which allows the grapes to evaporate more quickly during the drying process, and then the grapes are washed with water.

It is flattened on a grid by workers for a two- to three-month drying cycle.

Clause. 3. In this process, in order to allow all the grapes to be evenly dried, workers need to turn the grapes every two weeks until the moisture content in the raisins meets the standard, and then pour them into the destemming machine for the first impurity removal process. Larger vines are removed in the process, while smaller resins or fallen leaves need to be filtered through a vibrating sieve.

Next, the raisins are removed from the surface in a three-stage cleaning line to remove dust and bacteria from the surface, then dried by a dryer before being transported to the final packaging process via a conveyor belt. Here, the raisins that have been air-dried for several months only need to be blowered according to the requirements of the order and then ready for sale.

When learning grapes, choose grapes with thin skin and no seeds, after collecting, reduce the fruit grains of the wave and spread them in the fruit bowl to make it evenly heated, wash the grapes, let it be fully exposed to the sun, and then turn it from time to time, pinch the fruit with your hand and then when there is no grape juice penetration, put the dried fruit together and evenly remove the kernel, so that the raisins have been formed.

Choose the right fresh grapes, rinse them, and then dry them to turn them into raisins!

The grapes are compressed, the juice is removed, and then frozen in the basement and exposed to the sun.

Summary. Hello, a pound of grapes is expensive, and it sells well. If it's a large quantity, it's the raisins that are expensive, because there is still processing or something.

Nutritional differences between grapes and raisins. There is basically no difference in nutrition between grapes and raisins. 95% of the ingredients in grape seed are proanthocyanidins, and their antioxidant effect is 18 times higher than vitamin C and 50 times higher than vitamin E, so grape seed can be said to be a real antioxidant superstar.

It is an antioxidant and anti-aging method, so grape seeds can make you young forever. Which is more expensive, grapes or raisins? Raisins are generally more expensive than grapes.

There are two reasons for this. First, raisins are a relatively high-quality grape variety. Its planting and grafting technology is high, and the planting cost is higher than that of ordinary varieties.

Second, the high cost of transportation makes raisins sometimes twice as large as grapes. There is no difference between grapes and raisins in terms of nutrition, the difference lies in **.
