There are several processes that can be used in the production of dried fruit, each of which affects its appearance, rehydration properties, and nutrients differently. These drying processes include sun drying, tray (air) drying, freeze drying, and vacuum microwave drying. [22] Each process has its own benefits and disadvantages.
Microwave for approximately 30 seconds until melted, but not burned. 3. Using a wooden skewer, spear a piece of fruit and dip it into the melted sugar mixture, being careful not to drip hot sugar ...
Food drying is a method of food preservation in which food is dried (dehydrated or desiccated). Drying inhibits the growth of bacteria , yeasts , and mold through the removal of water . Dehydration has been used widely for this purpose since ancient times; the earliest known practice is 12,000 B.C. by inhabitants of the modern Asian and Middle ...
Additionally, sun drying is a slow process and may not produce the most desirable raisins. [5] Mechanical drying can be done in a safer and more controlled environment where rapid drying is guaranteed. One type of mechanical drying is to use microwave drying. Water molecules in the grapes absorb microwave energy resulting in rapid evaporation.
If the feed for drying is a solution, it can be dried using vacuum dryer as the solvent can be recovered by condensation. To improve the quality of products, such as for fruit preservation, hybrid drying combining osmotic dehydration followed by heat pump drying and microwave-vacuum drying proved effective. [1]
Researchers have found that microwave finish drying speeds up the otherwise very low drying rate at the end of the classical drying methods. Vacuum microwave drying is used for the US Army's experimental Close Combat Assault Ration. [3] Freeze drying or lyophilization is a drying method where the solvent is frozen prior to drying and is then ...
Goji, the fruit of Lycium barbarum – is usually sold in open boxes and small packages in dried form, and is traditionally cooked before consumption. The fruit is preserved by drying them in full sun on open trays or by mechanical dehydration employing a progressively increasing series of heat exposure over 48 hours. Gotgam (dried persimmon)
