K-TSHK | Total Starch Assay Kit (Hexokinase format)

Product code: K-TSHK

A modification of AOAC Method 996.11, AACC Method 76-13.01 and RACI Standard Method for the measurement, and analysis of total starch in cereal flours and food products. This kit contains an improved α-amylase that allows the amylase incubations to be performed at pH 5.0 (as well as pH 7.0). The method has been further modified by adjusting the D-glucose determination to a hexokinase/glucose-6-phosphate dehydrogenase/NADP+ based format.

Description

UV-method for the determination of Total Starch in grains,
animal feeds, foodstuffs and other materials

Principle:
(α-amylase, 100°C + DMSO)
(1) Starch granules + H2O → maltodextrins

(amyloglucosidase)
(2) Maltodextrins + H2O → D-glucose

(hexokinase)
(3) D-Glucose + ATP → G-6-P + ADP

(glucose-6-phosphate dehydrogenase)
(4) G-6-P + NADP+ → gluconate-6-phosphate + NADPH + H+

Kit size:                            100 assays
Method:                            Spectrophotometric at 340 nm
Total assay time:             ~ 90 min
Detection limit:                1-100% of sample weight
Application examples:
Cereal flours, food products and other materials
Method recognition:
AOAC (Method 996.11), AACC (Method 76-13.01), ICC (Standard
Method No. 168) and RACI (Standard Method)
