Embodiment 1

[0128] Preparation of Condensed Palatinose

[0129] 300 g of palatinose crystals and 90 g of water were added into a stainless steel container, stirred at 105° C. to dissolve, and then citric acid (0.02%, based on palatinose) was added. Condensate at 135°C under vacuum conditions, and keep the reaction for 30 minutes. The reaction product was dissolved in deionized water after cooling. The resulting solution was passed through the H + type cation exchange resin and OH - Type anion exchange resin for ion exchange to be purified. The following fractions were obtained by gel permeation chromatography:

[0130] The degree of polymerization ranges from 1 to 2%

[0131] The degree of polymerization ranges from 2 to 48%

[0132]The degree of polymerization ranges from 4 to 28%

[0133] The degree of polymerization ranges from 6 to 12%

[0134] The degree of polymerization ranges from 8 to 5%

[0135] The degree of polymerization ranges from 10 to 5%

[0136] The components ...

Embodiment 2

[0139] a) Hydrogenation of condensed palatinose

[0140] Get 500 milliliters of the reaction solution of 30% concentration obtained in Example 1, which contains 50% condensed palatinan, 2% monosaccharide and 40% isomaltulose, and the solution is adjusted under stirring with 1N NaOH pH to 7.8. The hydrogenation was carried out using nickel (wet weight 200 g) as a catalyst in the presence of hydrogen (150 bar) with stirring at 70°C.

[0141] Samples were taken at 0, 1, 2, 3 and 4 hours, and their isomaltulose content and 1,6-GPS (6-O-α-D-glucopyranosyl (1→6)- D-sorbitol) and 1,1-GPM (1-O-α-D-glucopyranosyl (1→1)-D-mannitol). When the quantitative free isomaltulose is converted into 1,1-GPM and 1,6-GPS, the hydrogenation reaction is ended.

[0142] Hour

[0143] After 4 hours of reaction, the isomaltulose contained in the condensed palatinose solution (see Example 1) was completely hydrogenated to 1,6-GPS and 1,1-GPM. The solution obtained after separating the ca...

Embodiment 3

[0150] Labeling of Hydrocondensed Palatinose

[0151] The hydrogenated condensation palatinose product separated in Example 2 was partially hydrolyzed with HCl according to the following conditions:

[0152] Take 0.9 ml of 1% hydrogenated palatinose, mix with 0.1 ml of 1M HCl, and react at 47° C. for no more than 8 hours. Samples were taken at 0, 1, 2, 4, 6 and 8 hours and analyzed by the HPAEC method.

Abstract

The invention relates to methods for producing condensed palatinose in hydrogenated form, to hydrogenated condensed palatinose produced thereby, to uses of this palatinose, and to foodstuffs and medicaments containing hydrogenated condensed palatinose.

Description

technical field [0001] The invention relates to hydrogenated condensed palatinose, a method for preparing the hydrogenated condensed palatinose, uses of the hydrogenated condensed palatinose, and foods and medicines containing the hydrogenated condensed palatinose. Background technique [0002] Free radicals are unstable, highly reactive atoms, molecules or residues with a lone pair of electrons. Free radicals are continuously generated in organisms through the biological oxidation-reduction reaction involving oxygen, or through the action of phagocytic cells. Free radicals are continuously generated in organisms through the biological oxidation-reduction reaction involving oxygen, or through the action of phagocytic cells. And in this process it is associated with pollution, ionizing radiation, ultraviolet radiation, and excess body waste. Due to their high reactivity, free radicals are a potential threat to cells and their components. In particular, it damages cellular ...
