Outline
To investigate the compliance between the labeled and plant-derived components in commercially available sweet potato starch and its products.
A total of 77 samples of sweet potato starch, sweet potato vermicelli and noodles were collected. Detection of sweet potato, cassava, potato and corn-derived ingredients was performed using real-time fluorescent polymerase chain reaction (PCR), and the labeling consistency of the products was evaluated.
The detection rate of sweet potato-derived components in the commercially available sweet potato starch and its products was 57.14%. Unlabeled plant-derived components were detected in 37.66% of the samples, primarily corn and cassava-derived components. The main labeling inconsistency in sweet potato starch was the detection of unlabeled other plant-derived components, while for sweet potato vermicelli and noodles, it was mainly the non-detection of sweet potato-derived components. The overall labeling consistency index for all samples was 38.96%. Specifically, the labeling consistency index was 43.59% for sweet potato starch and 34.21% for sweet potato vermicelli and noodles.
The discrepancy between the labeled and actual plant-derived components in commercially available sweet potato starch and its products is prominent. It is recommended to implement differentiated monitoring targeting the main inconsistencies found in sweet potato starch and its products to enhance the overall compliance level within the industry.
