Abstract

It has been found that probiotic-fermented carrot pulp has a beneficial effect in reducing blood glucose, more so than unfermented pulp. This paper explores the reason for this by looking at fermentation-induced changes in nutritional components and hypoglycemic effects of its polysaccharides. Micronutrient content showed minor changes, except for titratable acidity. Fat and protein decreased, while total carbohydrates increased. These polysaccharides are pectinic, and the number of total polysaccharides rose after fermentation. Scanning electron microscopy showed that the morphology changed from filamentous solid to spiral. The molecular weight of water-soluble polysaccharide (WSP) diminished after fermentation, while those of acid- and alkali-soluble polysaccharides increased. WSP had stronger hydroxyl radical scavenging activity in vitro, and WSP from probiotic-fermented carrot pulps showed better hypoglycemic effects than WSP from non-fermented carrot pulps in animal experiments. Thus, the fermentation-induced improvement in diabetes control from fermented carrot pulp probably arises from its WSP.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
