Malting process has minimal influence on the structure of arabinan-rich rhamnogalacturonan pectic polysaccharides from chickpea (.) hull.

The objective of the study was to determine the changes brought about by malting/germination on the pectic polysaccharides (PP's), the major components of soluble fibres present in chickpea (.) hull. Chickpea hull PP's were extracted sequentially using ammonium oxalate (AO) and ethylenediaminetetraacetic acid (EDTA), and a comparative study was conducted in native (unprocessed, N-PP) and after subjecting to 48 h malting process (M-PP).

Promising interaction between nanoencapsulated lutein with low molecular weight chitosan: characterization and bioavailability of lutein in vitro and in vivo.

This study aims to develop water-soluble low molecular weight chitosan (LMWC) nanoencapsules with lutein to improve its bioavailability. Lutein-LMWC nanoencapsules were prepared, characterized and bioavailability was studied in vitro and in vivo with lutein in mixed micelles (control). The particle size ranged between 80-600 nm, which was confirmed by Atomic Force Microscope.

Isolation, structural elucidation and immunomodulatory activity of fructans from aged garlic extract.

Traditionally, garlic (Allium sativum) is known to be a significant immune booster. Aged garlic extract (AGE) possesses superior immunomodulatory effects than raw garlic; these effects are attributed to the transformed organosulfur compounds. AGE is also known to contain fructans; the amount of fructans in AGE represents a small fraction (0.

Free radical-induced chitosan depolymerized products protect calf thymus DNA from oxidative damage.

Low molecular weight chitosan (LMWC) and chitooligosaccharides (COs), obtained by persulfate-induced depolymerization of chitosan showed scavenging of OH. and O2.- radicals and offered protection against calf thymus DNA damage.

Crosslinked chitosan--preparation and characterization.

Chitosan undergoes radical-induced depolymerization in the presence of potassium persulfate at 60 degrees C, leading to extensive crosslinking of the fragmented chains on subsequent cooling at 4 degrees C. As a result, a possible conformational change leading to higher crystallinity, as evidenced by IR, X-ray and 13C NMR was observed.
