A directly compressible composition includes more than 30% by weight of allulose. The directly compressible composition can form tablets. A method for the manufacture of allulose granules includes: a step (a) of preparing a granulation liquid comprising allulose; a step (b) of granulating powdery allulose, by applying the granulation liquid obtained in step (a) onto moving powdery allulose; a step (c), simultaneous with step (b), of drying the granules obtained in step (b); a step (c′) of maturation of the granules obtained in step (c); and a step (d) of recovering the granules obtained in step (c) or (c′).

The invention relates to a starch hydrolysate having a Dextrose Equivalent DE of between 5 and 30 and a specific carbohydrate profile. In particular, the hydrolysate of the invention has improved retrogradation behaviour. The invention also relates to a method for the production of said starch hydrolysate.

The present invention relates to maltooligosaccharides, the content of &#x3b1;-1,4-glycosidic bonds of which is between 70% and 80% of the total number of 1,4-type glycosidic bonds. The invention also relates to the method for manufacturing these maltooligosaccharides. Said maltooligosaccharides afford all the benefits of fiber-based foods, with an extremely low nutritional value. Such a compromise is particularly advantageous for use in healthy balanced diets, but also in the treatment and/or prevention of the pathology of diabetes. The invention also relates to the use of said maltooligosaccharides in the fields of human food and animal feed.

The present invention relates to a biological method for the dosage of peptidoglycans in a sample, especially a sample of glucose polymers.

Biological dosage of peptidoglycans

The present invention relates to a biological method for assaying peptidoglycans (PGN) in a sample, particularly a sample of glucose polymers. The PGN assay includes: a) treating the glucose polymer sample by sonication, heating, and/or alkalizing; b) placing the treated sample or a dilution thereof in contact with a recombinant cell expressing an exogenous TLR2 (toll-like receptor 2) and a reporter gene directly dependent on the signaling pathway associated with the TLR2. The reporter gene codes for a colored or fluorescent protein or for a protein the activity of which is measurable with or without a substrate; c) measuring the reporter gene signal; and d) determining the amount of PGN in the sample using a standard curve of the correlation between the amount or PGN and the strength of the reporter gene signal.

A method of producing arabitol by continuous fermentation of at least one sugar by micro-organisms producing arabitol, characterised in that arabitol is produced in a first fermentation area including at least one fermenter in such a manner that some of the sugar introduced into the fermentation medium is consumed by said micro-organisms, some of the fermentation medium obtained in this way is transferred into a second fermentation area including at least one fermenter, the volume being maintained constant in the first fermentation area by adding sugar, production of arabitol continues in said second fermentation area in such a manner as to consume the residual sugar of the fermentation medium, the fermentation medium thus obtained from said second fermentation area is separated a continuously into a fraction concentrated in micro-organisms and another, soluble fraction enriched in arabitol, and the arabitol thus obtained is collected.
