In 1832, H.A.L. Wiggers discovered trehalose in an ergot of rye, and in 1859 Marcellin Berthelot isolated it from trehala manna, a substance made by weevils, and named it trehalose. It can be synthesised by bacteria, fungi, plants, and invertebrate animals. It is implicated in anhydrobiosis — the ability of plants and animals to withstand prolonged periods of desiccation. It has high water retention capabilities, and is used in food and cosmetics. The sugar is thought to form a gel phase as cells dehydrate, which prevents disruption of internal cell organelles, by effectively splinting them in position. Rehydration then allows normal cellular activity to be resumed without the major, lethal damage that would normally follow a dehydration/rehydration cycle. Trehalose has the added advantage of being an antioxidant. Extracting trehalose was once a difficult and costly process, but circa the year 2000, the Hayashibara company (Okayama, Japan) confirmed an inexpensive extraction technology from starch for mass production.〔(【引用サイトリンク】url=http://www.just-food.com/news/cargill-hayashibara-to-introduce-trehalose-sweetener-to-the-americas_id90417.aspx )〕 Trehalose is currently being used for a broad spectrum of applications. == Structure == Trehalose is a disaccharide formed by a 1,1-glucoside bond between two α-glucose units. Because trehalose is formed by the bonding of two reducing aldehyde groups, it has no capacity to participate in the Maillard reaction. There is an industrial process where trehalose is derived from corn starch. There are at least 3 biological pathways for trehalose biosynthesis. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Trehalose」の詳細全文を読む スポンサード リンク
