BackgroundSaffron has gained people's attention and love for its unique flavor and valuable edible value, but the problem of saffron adulteration in the market is also serious. It is urgent for us to find a simple and rapid identification and quantitative estimation of adulteration in saffron. Therefore, the excitation‐emission matrix fluorescence combined with multi‐way chemometrics was proposed for the detection and quantification of adulteration in saffron.ResultsThe fluorescence composition analysis of saffron and saffron adulterants (safflower, marigold and madder) were accomplished by alternating trilinear decomposition algorithm (ATLD). The ATLD and two‐dimensional principal component analysis combined with k nearest neighbor (ATLD‐kNN and 2DPCA‐kNN) and ATLD combined with data driven soft independent modeling of class analogies (ATLD‐DD‐SIMCA) were applied for rapid detection of adulteration in saffron. 2DPCA‐kNN and ATLD‐DD‐SIMCA methods were adopted for the classification of chemical EEM data firstly with 100% correct classification rate. The content of adulteration of adulterated saffron was predicted by the N‐way partial least squares regression (N‐PLS) algorithm. In addition, new samples were correctly classified and the adulteration level in adulterated saffron was estimated semi‐quantitatively, which verifies the reliability of these models.ConclusionATLD‐DD‐SIMCA and 2DPCA‐kNN are recommended methods for the classification of pure saffron and adulterated saffron. N‐PLS algorithm shows potential in prediction of adulteration levels. These methods are expected to solve more complex problems in food authenticity.This article is protected by copyright.

“…So far, many studies have successfully used the strategy of combining EEM fluorescence spectroscopy with chemometric methods for food quality control and authenticity identification. 26–29 As a natural product, grape juice has complex components, but contains many endogenous fluorescent components, such as polyphenols and aromatic compounds. 30–32 Therefore, this work will use a strategy combining EEM fluorescence spectroscopy with chemometric methods for the identification and analysis of commercial reconstituted and sweetened grape juices.…”

Laggera pterodonta is a famous Chinese herbal medicine in China, which has the effect of treating viral infection, bronchial and sore throat. Yunnan Province of China is the main production area, and Laggera pterodonta grows in a wide range of areas in Yunnan Province. The climates of the respective growing places are also different, which may be different for the accumulation of medicinal components in it, and the evaluation of different the quality of the traditional Chinese medicine of Laggera pterodonta of origin is of great significance. At present, there was still a lack of reliable technology for the origin identification of Laggera pterodonta, especially the origin of Laggera pterodonta cannot be identified from the appearance, which was very difficult to evaluate the efficacy of Laggera pterodonta from different origins. Therefore, it is of great significance to develop a quick and easy method for the origin identification of Laggera pterodonta. Thirty-four samples of Laggera pterodonta from five main production areas of Dali, Jianshui, Lancang, Simao and Yuanjiang in Yunnan Province were used as the research objects. UPLC and PDA detector were used to collect fingerprints, the common peaks were obtained using the "Chinese Medicine Chromatographic Fingerprint Similarity Evaluation System (2012 Edition)", and then carry out PCA and OPLS-DA analysis by R and SIMCA-P, respectively. Laggera pterodonta from different origins can be distinguished by OPLS-DA, which was consistent with the PCA analysis results. Through the comparison of VIP values, 8 characteristic components with great differences are obtained, and the UV absorption of these characteristic components was mainly concentrated at 320-350 nm and 250-280 nm, possibly characteristic UV absorption of terpenes, sesquiterpenes, and alkaloids. Through the comparison of the standard products, it was confirmed that the two characteristic components were chrysosplenetin and artemisetin, and the quantitative analysis of these two compounds in the Laggera pterodonta from different origins was carried out. The results of variance analysis showed that the areas with the most significant difference in chrysosplenetin content were Lancang and Honghe (p=9.03×10-5), and the areas with the most significant difference in artemisetin content were Lancang and Simao (p=5.10×10-7). The Simao and Dali areas have lower levels of artemisetin than other areas, with the highest levels being the Lancang area. The content of chrysosplenetin in Dali area was lower than that in other areas, and the content was higher in Lancang area. It was speculated that Laggera pterodonta in Lancang area may be better than other origins in terms of quality and efficacy of Chinese medicinal materials. Chrysosplenetin can also be used as one of the important indicators for quality control and origin traceability of Laggera pterodonta. Using UPLC combined with chemometric methods, Laggera pterodonta from different regions of China’s Yunnan Province, can be effectively identified.
