The use of sulfur dioxide can be misleading. The right amount to help maintain color. The physical characteristics and nutritional value, as nature intended. While the use of excessive amounts of product to make a bad smell and the amount of residues exceeding the legal limit
of immersion sulfur. The easy way And a more rapid program Do this by soaking the fruits in a solution of potash, potassium meta bi sulfite. (Food grade Or grade used in the laboratory), 5-7% for 30 seconds or for Apple may be soaked in a mixture of sodium sulfite and sodium sulfite ratio of 1: 1 concentration 0.2-0.5% dip. If a piece of fruit to soak for 5 minutes to soak for 15 minutes, then cut in half the juice comes out. Rinse with water and bring to a downside to soak in a solution of sulfur dioxide

today. consumers are not the most popular dried fruits. The use of sulfur and more. You have to study and propose other ways. The use of sulfur To prevent browning during drying, such as
lowering the pH using citric acid or an organic acid other
techniques to reduce the moisture content to less rapid
use of antioxidant, such as ascorbic acid, tocopherol, cystein, glutathione
heat. Individual Quick Blanching as
reducing Aw using osmotic treatment
to reduce the pH acid Ascorbate Beith or vitamin C has the ability to prevent the substance from oxidation. You can help prevent Browning in fruit preparations for drying well. How to do this by dissolving acid Ascorbate Beith 1 teaspoon of water 1 cup shredded is then sprayed onto the fruit thoroughly. Or peaches soaked in acid solution Ascorbate Beith 1% and malic acid concentration of 0.25% for 3 minutes, then dried fruit. Dried fruit has to look better than the fruit is not soaked through so much. Or soaked in a solution of citric acid (citric acid) by dissolving citric acid 1 teaspoon (5 grams) in one liter of water soaking the fruits in a solution of acid and dried for 10 minutes to dry. There may also be soaked in juice with vitamin C. Although it is less effective than the use of pure Vitamin C or more. Juice the lemon juice, orange juice, grape juice, such as juice, etc. Each type will generate a unique color and flavor to the product. How to make a start by soaking the fruit in the juice to cover for 3-5 minutes, then baked to
scalding with hot water or steam. As a way to make some ripe fruit. Using steam or hot water before drying. The heat will help Destroying enzymes in the fruit, especially the polyphenol oxidase enzyme to break to indicate. The effectiveness of the process How often using continuous rather than a batch, which will take in the experience. With steam for about 2-10 minutes, some countries may take a scalding hot water in the well is controlled by solids. Soluble in water, stable to minimize losses in the scalding process. If a household scalding steam. Can be done easily by using the crates. By spreading the fruits in the tray with a thickness of up to 2 inches of imported steaming begins. Time to time cause burn them thoroughly. Some fruits may need to be returned, then the fruit Raiser mop water with paper towel before Bake

Individual Quick Blanching (IQB) is an adaptation of the usual scalding steam. The amount of water used and Solid waste (solid loss) decreased IQB system includes the steps of heating and maintaining heat in a condensing steam unit, starting with a piece of mesh belt arranged on one layer without overlapping. A density of about 1 pound / square foot. Moving quickly through the tunnel with the steam. All products are exposed to the steam and heated up quickly. The core of the product is very hot. The products are transported on a conveyor belt and stack another moving slowly. Through the insulation Long products in the chamber will be enough to destroy enzymes and makes the product has a good texture
with scalding syrup. The products are used for drying fruit. As a way to maintain good color. But it takes a long time to dry. How to Prepare the syrup By mixing 1 cup sugar, corn syrup (corn syrup) 1 cup and 2 cups water in a pot of boiling add 1 pound of fruit to soak for 10 minutes, lifting the pot and leave it for another 30 minutes and then took out the fruit. Rinse with plain water absorbs water and dried Osmovac drying process is a dry fruit that resembles a piece and sliced. How to start from the fresh fruit soaked in syrup, water (65 - 75 oBrix) or mixed with sugar or salt to get rid of. Water from tissues by a process of osmotic (osmosis) from such steps will be reduced. The amount of water is more than 50% of initial weight. Then be dried in the normal way to go. The concentration of sugar or salt levels will help prevent brown. The product dried That have good color without the use of sulfur dioxide. This approach also reduces discoloration and flavor. The heat used in drying. Reduce the time products are exposed to high temperatures. Soaked in syrup Reduces the loss of fresh fruit flavor was good. And reduces the amount of acid in some fruits make products. Has good taste more mellow. However, reducing the amount of acid and sugar content may increase. The problem occurs in some products, such as product stability during storage may vary. Because rancidity up Makes tough to stick together as a pack. And add to
