The concentrations of seven heavy metals (HMs) in jujube samples collected from Hetian region (HTR), Hami region (HMR), Erkesu region (ESR), Bayikuleng region (BLR), and Turpan region (TUR) were determined by inductively coupled mass spectrometry (ICP-MS). The accuracy and precision of the analytical method were confirmed by the certified reference material (GBW 07605). In general, the concentration of iron was higher than those of the other six metals in the investigated jujube samples. The Hazard Quotient (HQ) and Hazard Index (HI) were calculated to evaluate the noncarcinogenic health risk from individual metal and combined metals due to the dietary intakes via consumption of jujube. Both HQ and HI levels were far below 1, suggesting no noncarcinogenic risks for Xinjiang adults under the current consumption rates of the jujubes. Among the jujubes from five different regions, BLR jujube had the highest HQ and HI. Fe and As were the most concerning HMs in the investigated jujube samples due to their higher relative contributions to HIs.
Objective: To analyze the nutritional content of Shanxi's main vegetables and fruits.
Methods: According to the national food safety standards, the nutritional content of 25 vegetables and 38 fruits produced in Shanxi Province from 2018 to 2022 were evaluated for their energy, protein, fat, carbohydrates, vitamins, and minerals.
Results: The contents of energy and carbohydrate of the vegetable samples from high to low were allium, solanum and tender stems, leaves and cauliflower, respectively, The contents of protein from high to low were allium, tender stems, leaves, cauliflower and solanum; The contents of carotene, vitamin B_1, vitamin B_2 and vitamin E in solanaceous vegetables were the highest, and the contents of vitamin C were the tender stems, leaves and cauliflower vegetables.
The aim of this study was to evaluate the cytotoxic effects of enzymatically modified pectin products derived from grapefruit, jujube, and kumquat on the MKN-45 gastric cancer cell line in vitro. FTIR analysis revealed that the spectra of the pectins produced were comparable to those of commercial pectin and included the characteristic peaks identified in the literature. The galacturonic acid content was measured as 612 mg/g in grapefruit pectin, 544 mg/g in jujube pectin, and 704 mg/g in kumquat pectin.

Lactic acid bacteria (LAB) fermentation can enhance the quality and flavor characteristics of fruit juice. Herein, the impact of individual Lactiplantibacillus plantarum subsp. plantarum (L.
The serious impact of on jujube black spot disease has seriously affected the quality and yield of jujube, constraining the sustainable development of the jujube industry. The purpose of this study was to isolate and screen highly effective biocontrol strains of jujube black spot disease from jujube rhizosphere soil. Thirty-three soil samples were collected from four regions in southern Xinjiang.
The study aimed to identify the host plants of the Dusky Cotton Bug (), in various agro-ecological zones of Sindh, Pakistan, 2019. Samples were collected bi-weekly within 20 km of the Cotton Agriculture Research Station in each district of Sindh. The pest population is categorized into three levels: below 25; 25 to 49 and 50 or more adults and nymphs.
