Examples of using this product（for reference only）
UV
Standards were prepared using potato amylose (Solarbio, China) with a concentration gradient of 2%, 4%, 8%, 12%, 16%, 20%, and 32%. The absorbance of amylose content was determined at 600 nm. Total starch content was measured spectrophotometrically based on the determination of the absorbance of glucose concentration at 540 nm . According to the transformational equation between starch and glucose, total starch content was calculated by the following formula: Total starch content (mg·g-1) = glucose concentration × 10 × 9.11 ml × 0.9/(50 × 1000). Amylopectin content = total starch content - amylose content.
