In the current work, a deep study to understand the adsorption phenomena occurring in single and multicomponent systems was conducted by using spectroscopic characterization, and computational tools. The experimental results showed that the adsorption capacity of chili seed is higher for Pb (48 mg/g) than Cu (4.1 mg/g) ions in single systems. However, the adsorption study in multicomponent systems provides important conclusions of the concentration effect of the metal ions, showing a significant antagonistic and competitive effect of both ions under equivalent concentrations of them (q is 56% reduced) or high concentration of Pb (q is 50% reduced). Computational results correlated well with the experimental ones and evidenced all interactions proposed from spectroscopy results, accounting for the occurrence of complexation and electrostatic mechanisms between metal ions and the surface oxygenated functional groups (hydroxyl, carboxyl, and carboxylate) onto chili seed. Chemistry quantum descriptors supported the reactivity behavior of the chemical species implicated. All results evidenced that Pb and Cu adsorption on chili seed surface is governed by the occurrence of combined ionic exchange, π-interaction, complexation, and electrostatic attraction.

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.

This study explored convolutional autoencoder (CAE)-based feature extraction from entire two-trace two-dimensional (2T2D) correlation maps as a promising tool to enhance the accuracy of vibrational spectroscopy-based discriminant analysis. Although 2T2D correlation maps constructed using only a pair of spectra were effective to highlight minute spectral differences, there was an excessive number of features (variables). Thus, only slice spectra at a wavenumber chosen from the map were typically used for discriminant analysis.

Chili anthracnose, caused by , causes significant yield loss in chili production. In this study, we investigated the elicitor properties of a rhamnolipid (RL)-enriched PA3 fraction derived from SWUC02 in inducing systemic resistance in yellow chili seedlings and antifungal activity against CFPL01 (Col). Fractionation of the ethyl acetate extract yielded 12 fractions, with PA3 demonstrating the most effective disease suppression, reducing the disease severity index to 4 ± 7.

Identification and characterization of crop mutants through molecular marker analysis are imperious to develop desirable traits in mutation breeding programs. In the present study, macromolecular variations with altered morphological, quantitative, and biochemical traits were generated through chemically induced mutagenesis via alkylating agents and heavy metals. Statistical analysis based on quantitative traits indicating enhanced mean value in mutant lines selected from the M generation as compared to previous generations.
