- in the sun
- in the shade
Each of these two methods has advantages and disadvantages that are mentioned along with their training.
Eventually your raisins will be clean and healthy and you will be more comfortable with their health.
Sun drying (sun raisins)
Tie the bunches of grapes to a rope and hang them in the sun.
In the sunny method, depending on how sunny the area is and the ambient temperature, it takes 15 to 20 days for the grapes to dry completely.
Be sure to choose a place that is away from dust and air pollution.
Also, after a week and the top of the berries are dry, move them to dry the other parts as well.
The color of raisins prepared in this way is dark greenish brown.
Remove the dried grapes from the stem and store them in a cool, dry place.
Note: Although this method takes less time, but note that sunlight destroys a large amount of vitamins in grapes, especially vitamin A, vitamin B and vitamin C, and reduces the quality of your raisins.Drying under sun light decrease amount of nutrients specially vitamins like C, B and A
Drying in the shade (dry shade raisins)
Ordinary green raisins (dry shade)
In this method, different grapes are hung in the shade and cool air flow with less heat and gradually dry.
One of the best ways to make raisins at home is to dry the grapes in the shade.
To do this, after steps 1 and 2, hang the bunches of grapes with a rope in a covered environment where air flow is established.
In this method, it takes 50 to 60 days for the grape seeds to dry.
Raisins produced in this way are green and free of any contamination.
Gently remove the dried grapes, which are still slightly soft, from the stem and store them in a cool, dry place.
Note: Most of the vitamins in dried grapes are still preserved in this way and only have less moisture than fresh grapes.
Raisins in the shade of the sun
Another way to make homemade raisins is to hang the bunches of grapes with string and place them in the shade and exposed to air currents or mild heat.
The advantage of this method is that you can do it even at home and at room temperature and have a clean and healthy raisin without dust.
This type of raisin stays green, but on the other hand, preparing this type of raisin is a bit time consuming and takes 50 to 60 days.
It is also not very economical because it needs suitable halls.
They must be stored in a cool place and exposed to moisture, and if we put them in the freezer, or on the terrace and porch, their texture will be dry, hard and rough due to excessive cold or due to the exchange of moisture-free air.
How to make sunny raisins
One of the easiest ways to make raisins is to use the sun.
In this method, it is enough to put the fresh grape clusters on a plastic or a tray and expose them to the sun, and when the grapes are dry and brown, collect them in a plastic container and in a Keep in a dry place.
The essential time for drying the berries is 15-20 days, depending on the type of grape and the weather conditions.
In areas with early fall, early rainfall in some years damages the drying berries. Plastic tents are spread on the clusters to prevent rain damage. Some people hang the grapes with a string for better drying and do not have any contact with them until they are dry and brown.
Acid treated raisins or Tizabi
It is obtained by using acid solution.
In this method, the drying time of the berries is short and the coarseness of the berries is maintained during drying.
The color of the prepared raisins is yellowish green and soft.
Because in this method, the green color of raisins is preserved during drying and after drying it is very soft and it does not have the dryness of sunny raisins.
First, place the arranged clusters in the basket and immerse them in the prepared solution for one minute.
They are then placed in containers to drain and then transferred to an area, but the clusters should not be stacked.
And for uniform drying of the berries, by turning the clusters, they try to dry the lower part of the berries.
In this method, the drying time is 5-8 days.
One day after picking the spikes, they prepare a acidic water solution.
For this purpose, in 100 liters of semi-hot water, add 5 kg of commercial powder of potassium carbonate and 2 liters of green oil and stir the solution.
The obtained solution, which has a milky color, is sufficient for 2500 kg of grapes.
If the days when the grapes are dry are cloudy and the sun is weak, and if the clusters contain large berries, they increase the amount of potassium carbonate and the same proportion of green oil in the solution.
Potassium carbonate creates grooves on grape seeds, which cause the grape juice to dry faster and the raisins to form faster, as well as yellowing the raisins. Green oil also softens raisins.
