What is L-Arabinose

L-Arabinose is a naturally occurring pentose with  a sweet taste and is widely distributed as a component of complex non-starch polysaccharides in plant cell walls  and plant  gums. 

As a low-calorie sugar-substituting sweetener, the relative sweetness of L-Arabinose equals to half of the Sucrose's.  Some research suggested that L-Arabinose selectively inhibit sucrose absorption and then inhibit the increase of blood sugar.

Furthermore, L-Arabinose is an intermediate in flavor industry for producing flavors, the derivates of L-Arabinose can be used in the development of antiviral agents such as nucleoside.

History

-1970's,   L-Arabinose has been listed as GRAS flavor ingredient (No.3255) by The Flavor and Extract Manufacturers Association of the United States

-2003 or before,  L-Arabinose was approved as ingredient relative to blood sugar level for "Food with health claims (permit required for each item)" by Ministry of Health, Labour and Welfare of Japan. 

-2007, L-Arabinose was listed as food additive in Japan's Specifications and Standards for Food Additives (8th Edition)

-2008, L-Arabinose  was approved as new resource food which can be used as ingredient in general food by Ministry of Health of China  (Announcement No. 12 on 2008).

-2013 or before,  L-Arabinose was listed in  EAFUS (Everything Added to Food in the United States)  by USFDA.   (Doc no. 0088,  Doc type ASP)

- 2018, L-Arabinose is listed as food additive in Japan's Specifications and Standards for Food Additives (9th Edition)

Benefits

Sugar-substituting sweetener

L-Arabinose has a nice, sweet taste that does not linger in the mouth and has no aftertaste. No-calorie sweeter, it's not metabolized in humans. No side-effects were reported

Inhibiting sucrose absorption

The sucrase enzyme normally splits the sucrose molecule into one D-glucose and one D-fructose molecule. During the period that the sucrase enzyme is inhibited by L-Arabinose, the splitting of sucrose is delayed or even prevented, and the release of D-glucose and D-fructose to the blood is delayed.

Therefore L-Arabinose selectively inhibits the sucrase enzyme in the small-intestine in an uncompetitive manner.

Dosage: add 3% -5% L-Arabinose in Sucrose.

Raw material for Drug Synthesis

L-Nucleosides and their analogues have become useful agents for the treatment of viral diseases due in part to their good antiviral activity and generally low toxicity.
