애플리케이션

4-Hydroxybenzhydrazide has been used:
  • for determining the concentration of maltose from starch digestion
  • for analysis of sugars from fructan containing food hydrolysate
  • in colorimetric assay for reducing sugar estimation from processed feedstuff

생화학적/생리학적 작용

4-Hydroxybenzhydrazide (PAHBAH), is used for assaying α-amylase and glucoamylase activities. The assay based on PAHBAH measures non-specifically the free reducing sugar groups present in samples at 415nm colorimetrically.

Starch-containing food normally has complex components and structure, which control its digestion kinetic properties and nutritional value. However, interactions among multiple food components and their effects on starch digestion kinetics are rarely reported. Here, we evaluated the influence of tea

Combined analytical techniques were used to explore the effects of alkali treatment on the multi-scale structure and digestion behavior of starches with different amylose/amylopectin ratios. Alkali treatment disrupted the amorphous matrix, and partial lamellae and crystallites, which weakened starch molecular
