Probiotics are defined as live microorganisms that, when administered in adequate amounts, confer a health benefit upon the host. At present, probiotics are gaining popularity worldwide and are widely used in food and medicine. Consumption of probiotics is increasing with further in-depth research on the relationship between intestinal flora and host health. Most people pay more attention to the function of probiotics but ignore their potential risks, such as infection and antibiotic resistance transfer to pathogenic microbes. Physiological functions, effects and mechanisms of action of probiotics were covered in this review, as well as the antibiotic resistance phenotypes, mechanisms and genes found in probiotics. Typical cases of antibiotic resistance of probiotics were also highlighted, as well as the potential risks (including pathogenicity, infectivity and excessive immune response) and corresponding strategies (dosage, formulation, and administration route). This timely study provides an avenue for further research, development and application of probiotics.The volatile profile of 'Rama Forte' persimmon fruit treated with high concentration of CO2 or ethanol, as well as the association of specific volatile organic compounds (VOC) to the loss of astringency given by sensory and chemical evaluation were investigated in our study. Fruit were harvested at the maturity stage showing crisp texture and commercial color, and exposed to different astringency removal treatments 70% CO2 for 18 h or 1.70 mL kg-1 ethanol for 6 h. Fruit were daily assessed for VOC, astringency, and soluble tannins content throughout eight days at room temperature. The HS-SPME/GC-MS analysis allowed to tentatively identify 31 volatile compounds and two fatty acids. A clear separation of the persimmon fruit from the beginning to the end of the post-treatment period was showed by PCA results, mainly from the fifth day for CO2-treated and the seventh day for ethanol-treated persimmon. The loadings from CO2 treatment highlighted the increase in the concentrations of a great number of compounds with the progression of the days. The compounds 2,4-di-tert-butylphenol and 1-pentadecanal were tentatively identified on fruit from both treatments after the longest periods and were absent on astringent non-treated fruit. These compounds are reported for the first time on persimmon fruit. Astringency tending to absent was noticed from the fifth and the seventh day after the fruit exposition to CO2 and ethanol vapor, respectively, when flesh soluble tannins concentrations close to 0.1% FW were found. selleck inhibitor Our study indicates a strong relationship between the astringency removal and the compounds 2,4-di-tert-butylphenol and 1-pentadecanal, supporting them as potential marker compounds for artificial deastringency in 'Rama Forte' persimmon fruit.Peach palm fruit mesocarp (Bactris gasipaes var. gasipaes) is already consumed in the Northern region of Brazil, after its cooking and is known as a source of starch and carotenoids and like all fruits it has low storage stability. This work characterized the starch extracted from the mesocarp of peach palm fruit using with water in terms of its physical and chemical properties. The SEM micrographs show that starch presented bimodal distribution (size 3.9-10.4 µm), while the smaller granules had a smooth surface and an oval or conical shape, the larger granules were spherical with holes and cracks on the surface. The starch presented low amylose content ( less then 20%) and amylopectin branch chain length distribution with the absence of a shoulder, which is suggestive of perfect crystalline structure, and a higher proportion of medium chains (DP 13-24), despite the large number of short chains (DP 6-12), and on average DP 21. X-ray diffraction showed a mixture of polymorphs A and B, which can be considered C-type crystalline pattern, which is indicative of being a slow digestible starch. Through paste viscosity results, by RVA, we can observe low values for thermal and pasting properties, suggesting greater homogeneity of crystals. Also, due to interaction with lipids originally present (2.69%), the starch showed lower retrogradation rate (22.64%), which resulted in a weak gel after 24 h of storage. As a product with greater storage stability, peach palm fruit starch, extracted for the purpose of promoting its regional use, has shown that it can be used in products where slow and smooth retrogradation is desired, such as in breads, soups, chowder and porridges, without the use of emulsifiers or fat.Lentils are an important member of the nutritious Leguminous crops, and the functional properties of lentil flours can be effectively improved by infrared heating, an efficient and short-time thermal processing method. This research primarily focused on the effects of tempering time (24-96 h) and seed size on the modification of lentils using infrared heating. Lentil seeds of three varieties, including CDC Greenstar (large green), CDC Imvincible (small green), and CDC Maxim (small red), were tempered at 25% moisture for 24, 48 and 96 h and then infrared heated to a surface temperature of 130 and 150 °C. Overall, under the same infrared heating treatment, a longer tempering period and a smaller seed size led to greater degrees of starch gelatinization and protein denaturation. In addition, a smaller seed size and a higher surface temperature tended to cause a higher level of photodegradation of amylose (possibly amylopectin too). Due to these physicochemical changes, the combined treatment of tempering and infrared heating noticeably reduced the average particle sizes, enhanced the water-holding capacity, diminished the peak and final viscosities, and decreased the gel hardness of the processed lentil flours. Generally, more obvious effects were found with higher levels of starch gelatinization, protein denaturation, and breakdown of amylose. The present study advanced our understanding of how extended tempering and seed size influenced the techno-functional properties of lentil flours modified using infrared heating. The new findings from the research are meaningful for the utilization of infrared heating to process lentil seeds for the development of novel food ingredients.
