Each raisins originates from a single grapes that was allowed to wither and then preserve for sale. There are a great many distinct varieties of golden grapes(to be final nuts) , some of which are better suited for the production of wine or juice, while others are better suited for the production of table grapes or raisins. Grapes may be found all over the world. Table grapes are most commonly used to make table grapes for consumption and raisins for storage. Raisins are often made from the Thompson seedless grape, which is a common variety of grape that is used in the production of raisins. Picking the grapes is the first step in the process of transforming them into raisins. After the grapes have been gathered, the next step is for them to be dried. Because of this, they end up losing a considerable amount of weight and experiencing a considerable degree of shrinkage as a consequence. While dried black raisins contain less than 15% water, water makes up more than 75% of the volume of a fresh grape.
a defensive strategy or tactic One way to keep grapes fresh for an extended period of time is to make wine from them. Grape jam is another option. The grapes can also be allowed to dry out and then turned into raisins using this process. Raisins, on the other hand, can be stored for months without experiencing any degradation in quality, whilst grapes can only keep their crispness for a few days even when they are carefully managed, despite the fact that raisins can be stored for months. The low humidity guarantees that the vast majority of any germs that may have been present on the raisins are destroyed, ensuring that the raisins are safe for consumption. Raisins, on the other hand, have a water activity that falls somewhere between 0.5 and 0.6, in contrast to grapes, which have a water activity that is significantly higher than 0.9. On the other hand, grapes have a water activity that is substantially lower than 0.5. Grapes are a good example of this. (and can change depending on the type and the parameters of the processing). Before they were put into storage, the black raisins were sun-dried. When the sun's rays are the only source of energy used, the process of drying raisins can be completed in a matter of days rather than the weeks that would normally be required. Once raisins have reached the necessary level of dryness, they can be properly kept and processed in a manner appropriate for doing so. It usually takes a few weeks of being laid out on mats or mattresses for this to happen.

Raisins go through a series of physical transitions in addition to losing their moisture content as the drying process progresses. The warmth of the sun accelerates the chemical reactions that cause the raisins to brown, which is a typical feature of raisins. One of these reactions is the browning that takes place as a result of the activity of the enzymatic reaction, which is similar to what takes place when fruits such as apples or bananas are cut. The enzyme known as ppo is the one that is in charge of starting the process (polyphenol oxidase). The fact that drying in the sun is a natural process that is not always under the control of humans might cause the final color of the kishmish raisins to be different each time it is done. A drying procedure that is carried out more slowly while also being carried out at a cooler temperature for a longer period of time results in the production of raisins that have a lighter brown color.

Grapes that are grown specifically for human use are guaranteed to be plump and juicy, but they only have a few days before they begin to rot, particularly when the temperature is particularly warm. Methods of drying that include the use of machinery When making raisins, producers have the option of depending on mechanical drying processes rather than the natural process of exposure to sunlight to remove moisture from the fruit. Raisins go through a pretreatment process that helps them lose more moisture from their skin before they are dried. This is done before they are packaged and sold. One of the potential components of this therapeutic approach is submersion in an alkaline solution. Raisins, once they have been washed and processed, are able to be dried in tunnels with air circulating over them. This process takes place over the course of many days. The drying process for these steedless raisins just takes a couple of days, rather than the several weeks that is typical.
Grape raisins
The raisins' color will ultimately shift, but it doesn't matter what method is employed to dry them out; it will happen. The application of a treatment that contains sulfur dioxide is necessary in order to preserve the golden color of raisins (so2). Sulfur dioxide has the ability to either slow down or completely halt the chemical reactions that cause things to change color. Despite the fact that it is known to completely and irreversibly deactivate the ppo enzyme, its method and response are still a mystery. This is despite the fact that it is known to deactivate the enzyme. Golden raisins in comparison to regular raisins Even though sulfur dioxide (or a sulfite) is added to organic golden raisins in order to keep their yellow color, it is not always simple to discern the difference between regular raisins and golden raisins. Golden raisins are more expensive than regular raisins. If they are dried using the same technique, there will not be much of a discernible difference between the two after they have been dried. 
The majority of the raisin's textural variations can be linked to variations in the grape types that were used or the drying procedures that were utilized. Golden raisins are always dried by machine rather than by hand because of the additional processing that is necessary. On the other hand, raisins that are sold commercially are often sun-dried before being packaged. Both of these methods have the potential to bring about a significant transformation in the texture of the brown raisins . Some of the raisins are going to be substantially drier than the others, and some of them might even be burnt. However, there are going to be some green raisins that are significantly plumper than the others (if overheated). The phrase "la passa" comes from the Latin verb pandere, which derives from the passive verb passus, passa, passum, which means "stretched, spread out, and spread in the air to dry." The Latin verb pandere, in turn, comes from the Latin verb passus, passa, passum. This particular sense of the phrase was used for the first time around the tail end of the 14th century. 
The Phoenicians and the Egyptians are often credited with introducing raisins to the rest of the western world. This is due to the fact that they were the first people to consume this type of dried fruit, which was known for having exceptional nutritional value. This is due to the fact that they were the pioneers in the consumption of raisins. In antiquity, the Greeks and Romans frequently utilized them in the creation of medicine, as rewards in competitions, as cash, and even for the payment of taxes. In addition, they used them for all of these purposes.
