UPLC-PDA-ESI-MS based chemometric analysis for solvent polarity effect evaluation on phytochemical compounds and antioxidant activity in habanero pepper (Capsicum chinense Jacq) fruit extract.

The effect of solvents with different polarities on the recovery of phytochemicals (carotenoids, capsaicinoids, and phenolic compounds) from habanero pepper (Capsicum chinense) and their association with antioxidant activity (ABTS and DPPH) was evaluated through Ultra-Performance-Liquid Chromatography coupled with a Photodiode Array Detector and a Electrospray Ionization Mass Spectrometry (UPLC-PDA-ESI-MS)-based chemometric analysis, including linear correlation, multiple linear regression, and principal component analysis (PCA). The solvent polarity scale was established according to solvent dielectric constants (ɛ). Color variation (ΔE) was used to determine the presence of carotenoids, with the highest ΔE obtained using low-polarity solvents (hexane and ethyl acetate).

Enzymatic Crosslinked Hydrogels of Gelatin and Poly (Vinyl Alcohol) Loaded with Probiotic Bacteria as Oral Delivery System.

Probiotic bacteria are widely used to prepare pharmaceutical products and functional foods because they promote and sustain health. Nonetheless, probiotic viability is prone to decrease under gastrointestinal conditions. In this investigation, Lactiplantibacillus plantarum spp.

Optimization of 5-CQA Extraction Conditions from Green Coffee By-Product () Using a Response-Surface Design and the Study of Its Extraction Kinetics.

To take advantage of the residues generated in the production of products from green coffee and due to the special interest in the compounds contained in the bean, a by-product obtained after the extraction of the oil was studied. The physical characterization of the green-coffee-bean by-product was carried out. Subsequently, the extraction of compound 5-CQA was carried out via leaching using central composition design 24 and evaluating factors such as temperature, time, solid/solvent ratio, and ethanol percentage, and its yield was quantified using HPLC.

Estimation of metabolic fluxes distribution in Saccharomyces cerevisiae during the production of volatile compounds of Tequila.

A stoichiometric model for Saccharomyces cerevisiae is reconstructed to analyze the continuous fermentation process of agave juice in Tequila production. The metabolic model contains 94 metabolites and 117 biochemical reactions. From the above set of reactions, 93 of them are linked to internal biochemical reactions and 24 are related to transport fluxes between the medium and the cell.

Innovation in a Continuous System of Distillation by Steam to Obtain Essential Oil from Persian Lime Juice ( Tanaka).

The citrus industry is one of the most important economic areas within the global agricultural sector. Persian lime is commonly used to produce lime juice and essential oil, which are usually obtained by batch distillation. The aim of this work was to validate a patented continuous steam distillation process and to both physically and chemically characterize the volatile fractions of essential Persian lime oil.

Effect of PLA Active Packaging Containing Monoterpene-Cyclodextrin Complexes on Berries Preservation.

Blackberries and raspberries are highly perishable and fragile products, which limits their shelf life. The effect of biodegradable active packaging of blackberries and raspberries containing 2.5% and 5.

Phycocyanin content and nutritional profile of Arthrospira platensis from Mexico: efficient extraction process and stability evaluation of phycocyanin.

Phycocyanin is a blue natural food colorant with multiple health benefits. Here we propose an efficient phycocyanin extraction method from Arthrospira platensis from Mexico. Three extraction methods were applied to optimize the extraction process, using water and buffer as solvents, with three pH values at two agitation times.
