A process for the manufacture of mannitol in which: in a first step, a fructose syrup containing less than 15% glucose is subjected to an enzymatic isomerization using at least one enzyme capable of interconverting fructose and mannose, the enzymatic isomerization resulting in the production of a mixture of fructose and mannose containing at least 15% mannose, in a second step, the mixture of fructose and mannose is subjected to a chromatographic separation treatment so as to obtain at least two fractions one of which (fraction X1) is highly enriched with mannose and the other of which (fraction X2) is highly enriched with fructose, in a third step, fraction X2 is at least partially recycled to the top of the enzymatic isomerization step, in a fourth step, fraction X1, highly enriched with mannose, is hydrogenated so as to obtain a mannitol-rich syrup.

The invention relates to a process for continuous separation of mixtures of sugars and/or polyols. The mixture is fed to an installation comprised of at least 3 adsorbent filled columns connected in series. The columns represent absorption, enrichment and desorption zones respectively. The process provides for the continuous sequential operation of the columns as absorption, enrichment and desorption zones.

Process for hard coating with sorbitol and products obtained thereby

The invention relates to noncariogenic and sugarless chewing gum, and a process for manufacturing it. The chewing gum according to the invention is constituted by gum, by an aqueous softening agent and by one or several solid sweetening agents, of which notably mannitol, wherein the aqueous softening agent is at least partly constituted by a hydrogenated starch hydrolysate containing:

Sugarless-type chewing gum

The invention relates to a corn-steeping process. In this process the temperature of the steeping water decreases from silo to silo and the cycling ratio is comprised between 0.8 and 1.2 m.sup.3 per ton of commercial corn. The Corn-Steep obtained can be applied especially in the manufacture of penicillin.

Corn steeping process for products thus obtained and their use in the

The invention relates to a process for the recovery of .alpha.-hydroxy- and .alpha.-amino-carboxylic acids from sugary media containing them. According to the process of the invention:

Process for the recovery of .alpha.-hydroxy- and

Insoluble enzymatically active particles are produced by forming an intimate mixture of a jellifying protein such as gelatin and microbial cells containing an enzyme such as glucose isomerase, passing the mixture through a die to produce threads, passing the threads into cold water to jellify the threads, contacting the jellified threads with a crosslinking agent and cutting the resultant crosslinked threads into pieces.
