Sweet Fruit Used as Sugar Substitute and Medicinal Herb
by Subhuti Dharmananda, Ph.D., Director, Institute for Traditional Medicine, Portland, Oregon
Luohanguo is collected as a round green fruit that turns brown upon drying. The sweet taste of luohanguo comes primarily from mogrosides, a group of terpene glycosides, present at the level of about 1% of the fleshy part of the fruit (10). Both the fresh and dried fruits are extracted to yield a powder that is 80% or more mogrosides. The mogrosides have been numbered, 1-5, and the main component is called mogroside-5, previously known as esgoside (see chemical structure diagram below). Other, similar compounds from luohanguo have been labeled siamenoside and neomogroside. The mixed mogrosides are estimated to be about 300 times as sweet as sugar by weight, so that the 80% extracts are nearly 250 times sweeter than sugar; pure mogrosides 4 and 5 may be 400 times as sweet as sugar by weight.

A process for making a useful sweetener from luohanguo was patented in 1995 by Procter and Gamble Company (2). As described in the patent application, the fruit itself, though sweet, has too many additional flavors that would make it unsuitable for widespread use as a sweetener, so P&G developed a method for processing it to eliminate the undesired flavors. The fruit is seldom used fresh anyway, due to the problems of storing it; further, the raw fruit has unattractive flavors and a tendency to easily form off-flavors by fermentation; also, its pectin eventually gels. So, it is common to dry the fruits for any further use, and this is how they appear in Chinese herb shops. The fruits are slowly dried in ovens; the drying process preserves the fruit and removes most of the objectionable flavor of the fresh fruit, which is associated with volatile components. Unfortunately, the drying also causes the formation of bitter, astringent flavors. These flavors limit the use of the dried fruits and dried fruit extracts to the preparation of dilute teas and soups and products to which sugar, honey, and the like are added. In the P&G process, the fresh fruit is picked before ripening and allowed to complete its ripening during storage so that processing begins with the just-ripe fruit. The peel and seeds are then removed, and the mashed fruit becomes the basis of a concentrated fruit juice or puree that can be used in food manufacturing. Further processing involves using solvents to remove volatile and off-flavor components. Numerous sugar substitutes derived from luohanguo by similar processes that isolate the sweet compounds are now readily available for manufacturing and for kitchen use.
