This work evaluated nutritional and organoleptic properties of murta, a Chilean native berry, impregnated with Lactobacillus casei var. rhamnosus and dehydrated by different methods: freeze- (FD), convective- (CD) and vacuum- (VD) drying. Scanning electron microscopy revealed that L. casei localized at the peduncle and near the peduncle of the impregnated fruit. Murta enriched with probiotics contained higher L. casei viable counts after dehydration with FD compared to CD and VD methods. Overall, drying resulted in a decrease in crude fibre and phenolic compounds, which was attributed to L. casei metabolic activity suggesting that murta berries could act as prebiotics for L. casei. Among drying methods, L. casei enriched FD murta presented less alterations in the microstructure, less drying-induced damage and obtained a higher sensory acceptability score than CD and VD murta. Taken together, these results will contribute to the development of functional foods from regional products improving local economy.

Peripheral neuropathy (PN), the most common complication of diabetes, leads to sensory loss and associated health issues as pain and increased fall risk. However, present treatments do not counteract sensory loss, but only partially manage its consequences. Electrical neural stimulation holds promise to restore sensations, but its efficacy and benefits in PN damaged nerves are yet unknown.

In this study, an integrated approach combining UHPLC-HRMS, H NMR spectroscopy, and sensory analysis unveiled the unique lipid fingerprint of long-ripened Protected Designation of Origin (PDO) Coppa Piacentina. Lipidomic profiling revealed significant alterations in lipid classes, including triacylglycerols, sphingolipids, and their oxidation products, which likely contribute to the distinctive flavor, texture, and nutritional properties of this traditional Italian product. UHPLC-HRMS analysis identified various lipid species, highlighting dynamic changes occurring throughout the 240-day ripening process.

The levels of capsaicin (CAP) and hydroxy-α-sanshool (α-SOH) are crucial for evaluating the spiciness and numbing sensation in spicy hotpot seasoning. Although liquid chromatography can accurately measure these compounds, the method is invasive. This study aimed to utilize hyperspectral imaging (HSI) combined with machine learning for the nondestructive detection of CAP and α-SOH in hotpot seasoning.

Due to compositional differences, the mouthfeel of non-alcoholic beers (NABs) is considered inferior to that of alcoholic beers (ABs). Carbonation properties are a key sensation regarding mouthfeel. This study quantified the amount of bubbles in ABs (n = 10) and NABs (n = 9), ranging from 3.

This research article delves into Babaco fruit's-an Ecuadorian product with immense nutraceutical potential phytochemical composition and biological activity-in different maturation fruit stages. Bridging the gap between food and medicine, nutraceuticals offer health benefits beyond basic nutrition. Specifically, this study investigates Babaco's antioxidant and its phenolic and flavonoid content across different ripening stages: physiological maturity, organoleptic quality immaturity, and commercial maturity.
