Embodiment 1

[0049] In the pre-treatment step, 0.5094g of the raw material of traditional Chinese medicine extract produced by Changsha Jinnong Natural Plant Products Industry Co., Ltd. was weighed as the sample to be tested and 0.5071g of the excipient maltodextrin reference substance used in it were placed in 25mL volumetric flasks respectively. Dilute pure water to the mark, shake well, place in an ultrasonic water bath for 25-30min, pass through a 0.45μm filter membrane, and set aside. Then weigh 37.1mg and 40.5mg of maltose and maltotriose standard samples respectively and place them in a 20mL volumetric flask, add ultrapure water to constant volume, ultrasonic 5-10min, as the standard solution, and then dilute the maltotriose standard solution by 2, Dilutions were obtained after 4, 10 and 20 times.

Abstract

The invention relates to the field of food additive detection, in particular to a method for detecting the addition amount of maltodextrin in food materials. The method comprises steps as follows: preparing a to-be-detected sample solution, a maltodextrin control sample solution, a maltose standard solution and a maltotriose standard solution, and diluting the maltotriose standard solution in an assigned multiple into multiple parts; performing high-performance liquid chromatography analysis on the to-be-detected sample solution, the maltodextrin control sample solution, the maltose standard solution, the maltotriose standard solution and diluents of the maltotriose standard solution respectively, obtaining corresponding chromatographic peaks and retention time, drawing a maltotriose standard curve, obtaining the content of maltotriose in the to-be-detected sample solution and the maltodextrin control sample solution by the use of the maltotriose standard curve after the to-be-detected sample is determined to contain maltodextrin by comparing the corresponding chromatographic peaks and retention time, and calculating the ratio of the content of maltotriose in the to-be-detected sample to the content of maltotriose in the maltodextrin reference substance to obtain the addition amount of maltodextrin in the to-be-detected sample. The detection method which is wide in application range, simple in sample pretreatment, high in detection efficiency and high in accuracy is provided.

Description

technical field [0001] The invention relates to the field of detection of food additives, in particular to a method for detecting the amount of maltodextrin added in food raw materials. Background technique [0002] Maltodextrin is a cheap auxiliary material that is often added to health food raw materials. It itself is a complex mixture of monosaccharides, oligosaccharides and polysaccharides. There is currently no national standard for the content of maltodextrin in health food raw materials. Detection method. Although there are some detection methods for maltodextrin in the industry, such as sulfuric acid-phenol method, sulfuric acid-anthrone method, and enzymatic hydrolysis method, these detection methods have many disadvantages, such as complicated pretreatment, and are susceptible to other sugars in the sample background. The interference of similar substances, the accuracy is low, and the actual application effect is poor. [0003] Chinese patent literature (CN10479...
