Edible and medicinal plants (EMPs) are widely used but are easily infected by harmful fungi which produce mycotoxins. Herein, 127 samples from 11 provinces were collected to investigate 15 mycotoxins based on geographic, demographic, processing, and risk characteristics. A total of 13 mycotoxins were detected, and aflatoxin B1(0.56~97.00 μg/kg), deoxynivalenol (9.41~1570.35 μg/kg), fumonisin B1(8.25~1875.77 μg/kg), fumonisin B2(2.74~543.01 μg/kg), ochratoxin A (0.62~19.30 μg/kg), and zearalenone (1.64~2376.58 μg/kg) occurred more frequently. Mycotoxin levels and species were significantly different by region, types of EMPs, and method of processing. The margin of exposure (MOE) values was well below the safe MOE (10,000). AFB1exposure from Coix seed and malt consumption in China was of high health concern. The hazard Index (HI) method showed the range of 113.15~130.73% for malt, indicating a public health concern. In conclusion, EMPs should be concerned because of the cumulative effects of co-occurred mycotoxins, and safety management strategies should be developed in follow-up studies.Keywords:mycotoxins;coix seed;lilii bulbus;malt;lotus seed;risk assessmentKey Contribution:This study investigated the co-occurrence of mycotoxins in EMPs from China, and indicated a high risk of mycotoxin exposure from Coix Seed and Malt. Mycotoxin contamination in EMPs varied significantly, and it may require more explicit limits for specific EMPs.

This study aimed to evaluate the beneficial effects of polyphenol extract of adlay (Coix lacryma-jobi L. var. ma-yuen Stapf.) (PEA) on gut microbiota in rats fed a high-cholesterol diet (HCD). Rats were fed HCD containing 1% cholesterol (w/w), with or without a daily intragastric supplement of 200 mg/kg body weight PEA. Results showed that PEA significantly ameliorated increases in serum cholesterol and low-density lipoprotein cholesterol values and significantly restored high-density lipoprotein cholesterol values. The HCD-induced imbalance of gut microflora was modulated by the consumption of PEA. Most bacterial strains influenced by PEA are related to host lipid metabolism. The abundances of one Erysipelotrichales strains and two Clostridia strains were lower in the PEA group than in the control. Phenolic compounds in PEA were identified by HPLC. The findings indicate that PEA may be a useful dietary supplement in the treatment of elevated cholesterol levels and the imbalanced gut microbial ecology.

Edible films based on chitosan, coix seed starch (CSS), nano zinc oxide (ZnO) and Artemisia annua essential oil (AO) were obtained through solvent casting method. Physico-chemical, biological properties and structures of the edible film were analyzed and the preservation effect of it on the quality of cold-stored pork was also investigated. Fourier-transform infrared spectroscopy (FTIR) indicated that some possible intermolecular interactions could exist between film matrix and ZnO or AO. Scanning electron microscope (SEM) and thermogravimetry (TG) showed that ZnO and AO had good compatibility with the film biopolymers, no any phase separation. Results suggested that appropriate content of ZnO could enhance the film's compactness. Tensile strength (TS), barrier properties and antibacterial activities of the film was significantly enhanced with 5% ZnO was added. Incorporation of AO into the edible film decreased the TS, but increased the flexibility, barrier properties, antibacterial and antioxidant activities. When content of ZnO and AO were 5% and 8%, the physico-chemical, biological properties of the edible film could reach optimum. For pork preservation, pH, thiobarbituric acid reactive substances (TBARS), total viable count (TVC), and total volatile basic nitrogen (TVB-N) values of the pork which treated with 5% ZnO-8% AO film were significantly lowest (p ≤ 0.05) than other groups. Therefore, this edible film system has potential as food packaging materials.

Yin-deficiency-heat (YDH) syndrome characterized by inflammatory lesions is a common sub-health state in human body. Chrysanthemum and coix seed are commonly used to improve YDH syndrome. The chemical, volatile, and phenolic profiles and sensory and functional properties of five plant-based solid beverages (PSB) prepared by hydrothermal treatment coupling with enzymatic hydrolysis by amylase and protease using chrysanthemum and coix seed as materials were determined. Chrysanthemum-coix seed beverage had wonderful water solubility, reduced bitter and sour taste, sweet taste, and harmonious aroma. Chrysanthemum phenolics extracted by enzymatic hydrolysis might impact multiple metabolic pathways and biological processes to intervene in inflammation and most of them had high bioaccessibility. PSB promoted the production of beneficial gut microbiota metabolites. Chrysanthemum-coix seed beverages exerted more positive effects on YDH syndrome due to anti-inflammatory phenolics from chrysanthemum and resistant starch/dextrin from coix seed facilitating short-chain fatty acids production. This study provided new sight for developing plant-based beverages with anti-YDH syndrome potential.

Herein, we present a bifunctional gold nanoparticles (AuNP) probe-based enzyme-linked immunosorbent assay (nano-ELISA) for detecting zearalenone (ZEN) in the popular edible and medicinal food coix seed. This nano-ELISA takes advantage of the convenient labeling property of AuNPs, which allows the horseradish peroxidase and antibody were successively immobilized onto AuNPs by electrostatic adsorption to construct a bifunctional probe for identification and signal amplification. In our model system, a time-saving direct competitive ELISA scheme was selected, in which mutual optimization of biomolecules, a two-stage process for incubation, and comparison of different particle sizes were performed to reach higher sensitivity. The proposed method achieves a limit of detection of 8 μg/kg and a limit of quantitation of 22 μg/kg, which is an approximately 7-fold and 5-fold improvement over the traditional ELISA, respectively. The calibration curve for the analyte was linear over the concentration range of 22–508 μg/kg. The recoveries for ZEN spiked coix seed samples ranged from 98.67 to 113.5 % with a relative standard deviation of less than 8 %. Moreover, the developed nano-ELISA could overcome the interference from the sample matrix. A good correlation was observed between the results from nano-ELISA and liquid chromatography-tandem mass spectrometry (r 2 = 0.9757, n = 69), which paves the useful and practicable way for accurate bioanalysis for trace hazardous substances in food.

Probiotic fermentation is attractive for beverage processing. However, its regulatory role in quality of coix seed-chrysanthemum beverage (CCB) rich in phenolics and polysaccharides was unknown. Results showed that co-fermentation with Bifidobacterium animalis subsp . lactis BLa80 (BLa80), Lactobacillus delbrueckii subsp . bulgaria LB42 (LB42), Streptococcus salivarius subsp . thermophilus ST81 (ST81), and Lactobacillus plantarum LP90 (LP90) for 12 h combined their respective advantages to prepare fermented CCB with viable counts of 8.78 lg CFU/mL, high phenolics bioaccessibility (>60 %), good sensory quality, and strong antioxidant activity . LP90 greatly contributed to the aroma. BLa80 and LP90 hydrolyzed resistant starch/polymer dextrin . BLa80 showed the strongest deglycosidic ability, decreasing bitterness. The compound probiotic fermentation led to the biotransformation of endogenous polysaccharides/phenolics and introduction of exogenous viable probiotics resistant to gastrointestinal digestion, facilitating the proliferation of beneficial gut microbiota and accumulation of their metabolites. These findings provided a useful strategy for dual regulation of high quality of plant-based beverage.
