Abstract

The invention discloses a method for conducting near-infrared rapid detection on the component content in infant formula rice flour. The components include protein, fat, dietary fibers, water and ash, and infant formula rice flour samples are collected, sorted and numbered; parameters capable of influencing near-infrared spectrums of the samples are optimized, the optimal parameters are determined, the sample spectrums are collected, and the calculated average value of near-infrared spectrum data is obtained; a partial least square method is utilized in combination with the component content in the samples measured through a standard determining method; then selection of the optimal pretreatment method and the modeling wave band is conducted; near-infrared analysis model of the protein, the fat, the dietary fibers, the water and the ash in the infant formula rice flour are established respectively; the component content in the samples of the infant formula rice flour to be detected is predicated. According to the method, pretreatment and chemical reagent are not needed, the method is easy to operate, efficient and environmentally friendly, the predicated results meet the requirement for the precision of the standard determining method, and obvious difference does not exist in statistic and analysis results.

Description

technical field [0001] The invention relates to the technical field of rapid food detection, in particular to a near-infrared rapid detection method for ingredient content in rice noodles for infants and young children. Background technique [0002] Infant formula rice flour is one of the main food and nutrition sources for infants and young children other than breast milk and milk powder. Formula rice noodles are divided into stages, and the nutrients contained in different stages are also different. Children in infancy and toddlerhood are growing and developing, their stomach capacity is not large, and every meal is to meet the needs of growth. Moreover, the food that infants and young children can eat is also limited, especially for children who have just added complementary foods, baby rice noodles may be the only food for children besides milk. [0003] The national standard method for the determination of protein, fat, dietary fiber, moisture and ash in rice noodles ...
