Article Synopsis
  • Edible mushrooms have the ability to influence gut bacteria, with this study focusing on the prebiotic effects of digested mushroom powder (MUS) during colonic fermentation.
  • MUS contains phenolic compounds like epicatechin, gallic acid, and quercetin 3-glucoside, which were shown to enhance the growth of beneficial bacteria while reducing the presence of less helpful strains.
  • The study found that MUS boosts the production of lactic acid and short-chain fatty acids, lowers pH levels, and contains essential amino acids, indicating its potential health benefits for human gut microbiota.

This study evaluated the effect of dielectric barrier discharge (DBD) and glow discharge (glow) cold plasma treatments in color, sugars, organic acids, phenolics (concentration and bioaccessibility), antioxidant activity, volatiles, and microbiota of edible mini-roses. Plasma treatments did not affect the flowers' color, while they increased organic acids and phenolics. Flowers treated with DBD had a higher concentration of most phenolics, including hesperidin (84.

This study aimed to evaluate the functional, technological, and sensory aspects of mangaba (Hancornia speciosa Gomes) fruit pulp fermented with the probiotic Lacticaseibacillus casei 01 (LC1) during refrigerated storage (7 °C, 28 days). The effects of the fermented mangaba pulp on the modulation of the intestinal microbiota of healthy vegan adults were also assessed. Mangaba pulp allowed high viability of LC1 during storage and after simulated gastrointestinal conditions (≥7 log CFU/g).

A protein hydrolysate of goat viscera added with xylose, cysteine, and thiamine under different pH was used to prepare a meat flavoring. Goat viscera hydrolysate and flavoring were subjected to analysis of physicochemical characteristics, amino acid profile, sugars, fatty acids, and volatile profile. Meat aroma characteristics were initiated in the hydrolysate, in which Strecker's pyrazines and aldehydes were identified, which also had fatty acids and amino acids available for the formation of 96 volatile compounds in the flavorings via lipid manipulation, Maillard occurrence, Strecker manipulation and interactions among these means.

  • High-intensity ultrasound (HIUS) was used instead of pasteurization for a water-soluble Baru almond extract to create probiotic fermented beverages.
  • Four different formulations were tested: untreated, pasteurized, ultrasound before fermentation, and ultrasound after fermentation, with various impacts on nutrient quality and consumer acceptance.
  • The formulation that used HIUS after adding probiotics (U-BEF) not only reduced fermentation time and improved probiotic survival but also enhanced sensory properties, suggesting it may be a better processing method than traditional pasteurization.

Currently, analysis of interim PET (iPET) according to the Deauville score (DS) is the most important predictive factor in Hodgkin lymphoma (HL); however, there is room for improvement in its prognostic power. This study aimed to evaluate the prognostic value of quantitative PET analysis (maximum standard uptake value [SUV], total metabolic tumor volume [TMTV] and total lesion glicolysis [TLG]) at baseline (PET0) and iPET in a retrospective cohort of newly diagnosed classical HL. For positive iPET (+ iPET), the reduction of quantitative parameters in relation to PET0 (ΔSUV, ΔTMTV and ΔTLG) was calculated.
