Sucrose is the most commonly used solute in the osmotic dehydration (OD) of fruits. However, there is increasing interest in replacing it with other alternative sugars. Polyols are carbohydrates with low glycemic, insulinemic, and cariogenic indexes. Therefore, this work aimed to study the influence of the type of osmotic agent (sucrose, erythritol, or maltitol) and vacuum application on mass transfer and phys. and nutritional changes in 10-mm edge strawberry cubes. OD was performed with or without vacuum application during the first 20 min in a total process time of 300 min. Higher solid gain, water loss and weight reduction, and lower water activity and moisture content were observed by using erythritol solution The vacuum application strengthened this behavior. The color of the samples was affected by factors. Osmotic processes reduced the total anthocyanin content (TAC), showing that leaching is an important qual. flow during osmotic processes. Novelty impact statement : Polyols showed good potential as an osmotic agent in the osmotic dehydration of strawberries and are a good alternative to the use of sucrose. Osmotic dehydration promoted a satisfactory impregnation of polyols in the strawberry, mainly with the application of vacuum, in which the mass exchange rates were increased. However, leaching was an important flow of anthocyanin loss from strawberries to the osmotic solution In the experiment, the researchers used many compounds, for example, (2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6Recommanded Product: 149-32-6).
(2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Recommanded Product: 149-32-6
