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.

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 the fruits of grapes under the sun, raisins are most famous for raisins in Xinjiang, in fact, we can make such delicious raisins at home, but we have not yet mastered the scientific method, so we will introduce you to how to make family-style raisins, let's see how to make homemade raisins.

1. Selection of raw materials: Dried grapes should be made with thin skin, plump and soft flesh, beautiful appearance and high sugar content. The fruit should be fully ripe, but not too ripe.

2. Cut the skewers: After harvesting, cut off the fruits that are too small and damaged, and cut the fruit bunches that are too large into several small skewers, and lay a layer on the drying plate.

3. Soda immersion treatment: In order to speed up drying and shorten the evaporation time of water, lye treatment can be used. Impregnate in a solution of sodium hydroxide at a concentration of 1 5 seconds, and thin skins can also be treated with sodium carbonate or a mixture of sodium carbonate and sodium hydroxide at a concentration of 3 to 6 seconds.

After the raw material is soaked in alkali, it is immediately rinsed in clean water. The drying time of the fruit after maceration treatment can be shortened by 8 to 10 days. When drying white raisins, it is also necessary to smoke sulfur for 3 to 5 hours.

4. Exposure: Put the grapes into the drying tray, expose to the sun for about 10 days, when the surface is partially dry, you can turn it all over, put it on the surface layer and continue to dry it, until two-thirds of the fruit is dry, and when the fruit is not exuded by grape juice, you can fold the drying tray and dry it in the shade for a week. In sunny weather, the total drying time is about 20-25 days.

The ordinary way to make raisins.

In general, we make our own raisins, and choose fresh grapes such as "seedless white", "seedless dew", "rose-scented" and "milk" with seeds, and the fruit is fully ripe.

After harvesting, cut off the ones that are too small and damaged, and the bunches of fruits should not be too large, and the large ones should be cut off in small bunches and spread a layer on the drying plate. Exposed to the sun for about 10 days, when the surface is partially dry, you can turn it all over, put it on the surface layer and continue to dry it, until two-thirds of the fruit is dry, and when the fruit is not oothed by hand, you can stack the drying tray and dry it in the shade for a week. In sunny weather, the total drying time is about 20-25 days.

Then stack the fruit bunches for 15 to 20 days to dry them evenly, and at the same time remove the fruit stalks, that is, the finished product.

How to make Turpan.

In Turpan, Xinjiang, ripe grapes are dried in a ventilated room after alkali maceration. Turpan has a hot and dry climate, and the walls of the brick drying room are covered with plum blossom holes, and in the middle are wooden sticks to build the ripe seedless grapes.

After about 40 days of hot and dry air, it is done. Raisins made by this shade-drying method are of excellent quality, translucent, and do not change color.

The fruit of raisins is ripe, and the water content in raisins is only 15-25%, and the fructose content is about 60%, so it is very sweet.

As a result, raisins can be stored for a long time, and the fructose in raisins may crystallize over time, but this does not affect their consumption. Raisins can be eaten as a snack or in pastries, and in some places cooking edible raisin dressing.

Raisins that are dried in the sun are prone to sourness, and those of better quality are dried in the shade.

Raisins are known to be a delicious snack, and now raisins can also be used as an ingredient in other food products, such as raisin shaqima, raisin cakes, and many more.

1. Raw material selection: Dried grapes should be selected with thin skin, plump and soft flesh, beautiful appearance, and high sugar content, and the fruit should be fully ripe and not too ripe.

2. Soda soaking treatment: in order to speed up the drying and shorten the water evaporation time, lye treatment can be used, and the raw materials can be rinsed in clean water immediately after soaking soda treatment, and the drying time of the fruit after soaking alkali treatment can be shortened by 8 10 days, and when drying raisins, it also needs to be smoked for 3 5 hours.

3. Exposure: Put the grapes in a drying tray and expose them to the sun for about 10 days, and in sunny weather, the total drying time is about 20 to 25 days.

Analysis: 1 Selection and processing of raw materials.

1) Selection of raw materials Dried grapes require thin skin, thick and soft flesh, medium to small fruit shape, high sugar content, strong flavor, preferably seedless, and fully ripe.

2) Washing The main purpose is to remove surface dirt and pesticide residues.

3) Blanching Blanching can inactivate the activity of enzymes, reduce oxidative discoloration and loss of nutrients; Removing air from the fruit and improving the appearance of the dried product; Sterilization and disinfection. Hot water or steam can be used for blanching, and the processing time varies depending on the variety, and it is generally completely passivated by peroxidase.

4) Sulfur treatment Sulfur treatment can improve the color of the finished product, preserve vitamin C to the greatest extent, and play a role in sterilization and insecticide. There are two commonly used treatment methods: fumigation and sulfur immersion. During fumigation, the concentration of sulfur dioxide in the fumigation chamber is high.

Sulfur is required to be pure and contain less impurities, of which the content of arsenic should be less than. Generally, for every 1000kg of raw materials, 2 4kg of sulfur is required. In sulfur immersion treatment, the usual concentration of sulfurous acid solution is 1% 3%.

Sulfur immersion treatment can be carried out before drying, and fumigation is generally used after drying.

2 Drying method.

The processed fruit ears are slightly trimmed, naturally dried on the plate for about 10 days, flipped, and continued to dry until the fruit grains are pressed by hand without juice oozing, and stacked in the drying plate to dry. Turpan and other places in Xinjiang often hang grapes indoors and dry them for ventilation. When the indoor temperature reaches about 40, it takes about 30 days.

In order to shorten the drying time, the grapes can be soaked in alkali treatment, generally soaked in sodium hydroxide solution for 1 5s, sodium carbonate or a mixture of sodium carbonate and sodium hydroxide for 3 6s for thin-skinned varieties, or low-concentration hot lye solution, such as sodium hydroxide solution, can be soaked for a few seconds.

The moisture content of finished raisins is generally 12% 15%, and the drying rate is 3 1 4 1. After drying, it takes 3 weeks to soften and then destemmed and packaged.
