The leaves of the bilberry (Vaccinium myrtillus L.) represent a significant by-product of berry cultivation, and are a source of beneficial phenolic compounds that positively impact human health. In a pioneering effort, ultrasound-assisted extraction, facilitated by a sonotrode, was utilized to recover bioactive compounds from bilberry leaves for the first time. The extraction method was optimized using a meticulously designed Box-Behnken experiment. Considering total phenolic content (TPC) and antioxidant capacity (DPPH and FRAP assays) as dependent variables, the influence of ethanol-water volume ratio (v/v), extraction time (minutes), and amplitude percentage (%) were examined through response surface methodology (RSM). Optimal performance was achieved by employing 3070 ethanol/water (v/v), 5-minute extraction times, and a 55% amplitude as independent variables. The empirical values of the independent variables under the optimized process were 21703.492 milligrams of GAE per gram of dry weight. The 27113 TPC sample contains 584 milligrams of TE per gram of dry substance. 31221 930 mg TE/g d.w. of DPPH was a significant factor in the experiment. This JSON schema, list[sentence], is requested. Through ANOVA, the validity of the experimental framework was established, and the ideal extract was further characterized using HPLC-MS. A preliminary analysis identified 53 compounds, 22 of which were observed in bilberry leaves for the first time. The identified phenolic compounds featured chlorogenic acid as the most abundant molecule, representing a proportion of 53%. Subsequently, the antimicrobial and anticancer activities of the optimal extract were put to the test. Bilberry leaf extract exhibited potent in vitro activity against gram-positive bacteria, demonstrating minimal inhibitory concentrations (MICs) of 625 mg/mL for Listeria monocytogenes, Listeria innocua, and Enterococcus faecalis, and a considerably lower MIC of 08 mg/mL for Staphylococcus aureus and Bacillus cereus. In vitro studies revealed that bilberry leaf extract exhibited antiproliferative properties against colon tumor cell lines HT-29, T-84, and SW-837, with IC50 values of 2132 ± 25, 11403 ± 52, and 9365 ± 46 µg/mL, respectively. Consequently, this rapid ultrasound-assisted extraction procedure has proven to be a highly effective method for obtaining bilberry leaf extract, exhibiting in vitro antioxidant, antimicrobial, and anticancer properties. These properties hold potential applications within the food industry, such as natural preservatives or the development of functional foods and nutraceuticals.
An investigation into the influence of HYP (10, 50, and 250 M/g protein) on the physicochemical and gel properties of myofibrillar proteins (MPs) was undertaken across varying NaCl concentrations, while considering oxidative stress conditions. Independent of NaCl concentration, the inclusion of HYP caused a dose-dependent reduction in carbonyl content and decreased the loss of free amine groups. Subsequently, HYP caused a dose-dependent decrease in the amount of total sulfhydryl content, irrespective of the NaCl level, which could be attributed to the formation of thiol-quinone adducts via Michael addition. Surface hydrophobicity was considerably amplified by the presence of HYP. Nevertheless, a marked decrease in surface hydrophobicity was observed in samples treated with 250 mg/g HYP in comparison to those treated with 50 mg/g HYP, a change likely driven by increased myoglobin unfolding and subsequent aggregation via hydrophobic bonding. Similarly, HYP displayed a dose-dependent rise in the water-holding capacity (WHC) and gel firmness of MPs gels, which might be explained by more organized cross-links through fibrous filaments at 0.2 M NaCl and more uniform, stratified structures with smaller and more consistent pores at 0.6 M NaCl. To summarize, HYP mitigated oxidation-induced modifications to the physicochemical properties, thus shielding MPs from oxidative damage and bolstering the organized cross-linking between MPs-MPs and MPs-HYP during thermal gellation, ultimately yielding superior gel characteristics. The practical application of HYP as a natural antioxidant in gel-type meat products finds theoretical backing in these findings.
The abundant game species, the wild boar, boasts high reproduction rates. Meat obtained from wild boar hunting, part of population management strategies, assists in minimizing zoonotic disease transfer to domestic pigs, thereby impacting food security positively. Equally, the presence of foodborne zoonotic pathogens in wild boars compromises food safety. We examined relevant literature spanning 2012 to 2022, concerning biological hazards, which are addressed in European Union regulations and international animal health standards. From our investigations, we identified 15 viral, 10 bacterial, and 5 parasitic agents. We subsequently chose nine zoonotic bacteria that are transmissible to humans through food. In wild boar, the levels of Campylobacter, Listeria monocytogenes, Salmonella, Shiga toxin-producing E. coli, and Yersinia enterocolitica found on or in muscle tissue spanned a significant range, from a complete absence to approximately 70% occurrence. The experimental research highlighted the transmission and viability of Mycobacterium within the wild boar's meat. Samples collected from the liver and spleen included Brucella, Coxiella burnetii, Listeria monocytogenes, and Mycobacteria. The occupational risk associated with Brucella was a key finding in multiple studies, but transmission via meat remained undetected. Additionally, the transmission route for *C. burnetii* is most likely facilitated by vectors, specifically ticks. With limited detailed information available for the European Union, concentrating efforts on the efficiency of existing game meat inspection and food safety management systems is important.
The Clitoria ternatea (CT) blossom boasts a wealth of phytochemicals. CT flower extract (CTFE), a naturally pigmented, functional component, was ingeniously incorporated into noodles utilizing an innovative approach. Examining the impact of CTFE (0-30%) on the color, texture, phytochemicals, and sensory profile of dried and cooked noodles was the goal of this study. biosphere-atmosphere interactions Dried noodles containing 30% CTFE exhibited the greatest total anthocyanin content (948 g/g), polyphenol concentration (612 g/g), DPPH radical scavenging capability (165 g TE/g), and reducing power (2203 g TE/g). During cooking, there was a substantial decrease in anthocyanin levels and the blue coloring of the noodle, accompanied by a noticeable increase in the noodle's green hue. Noodles, both dried and cooked, with 20-30% CTFE, demonstrated a substantially greater preference for color than the control. The incorporation of 20-30% CTFE into cooked noodles, while resulting in a significant decrease in cutting force, tensile strength, and extensibility, did not affect the sensory qualities, such as flavor, texture, and overall preference, compared to those of noodles with 0-30% CTFE. The incorporation of 20-30% CTFE can produce blue noodles boasting high phytochemical content, potent antioxidant activity, and appealing sensory characteristics.
The average intake of salt commonly exceeds the optimal level. In the context of low-sodium food engineering, augmenting the perception of saltiness through the use of flavor enhancers that deliver an umami taste is a viable and promising method. To ascertain the impact of split-gill mushroom (SGM) powder’s umami flavor on the saltiness of clear soup, two different heating methods, high-pressure steaming and microwave heating, were evaluated in this study. According to the E-tongue data, a taste variation occurred in the soup upon including 2-8% SGM, in contrast to the use of salt. Furthermore, the E-tongue study noted a comparable flavor profile between 2-8% SGM and 4-6% MSG in the context of a transparent, plain soup. Within flavored soup, the taste-augmenting potential of SGM at a high concentration closely mirrored that of 0.4% MSG, but a low SGM concentration revealed no taste-enhancing attributes. Adenosine 5'-monophosphate (5'-AMP) and guanosine 5'-monophosphate (5'-GMP), two umami 5'-nucleotides, were found in 0.4% or 0.8% SGM flavored soups; however, no inosine 5'-monophosphate (5'-IMP) was detected. Glutamic acid, aspartic acid, and arginine were the principal umami amino acids. Microwave heating increased the concentrations of salinity and total nucleotides, and retained the umami amino acids. In stark contrast, high-pressure steaming resulted in an 823% decrease in the amount of aspartic acid, one of the umami amino acids. Worm Infection Subsequent to microwave heating and high-pressure steaming, the equivalent umami concentration was found to decrease by 4311% and 4453%, respectively. Ultimately, incorporating SGM and microwave volumetric heating presents a viable alternative for minimizing salt in soup while enhancing umami flavor and perceived saltiness.
Impurities co-eluted with the target analyte and the matrix itself contribute to the change in analytical signal, a phenomenon known as the matrix effect. Quantification of constituents in crop samples using liquid chromatography-tandem mass spectrometry is susceptible to matrix effects, which can alter the results. Due to the presence of phytochemicals and chlorophyll, Chinese chives are expected to generate a substantial matrix effect during the simultaneous extraction of bifenthrin and butachlor. A newly developed analytical method effectively mitigated the matrix influence of bifenthrin and butachlor in Chinese chives. The established quantification method demonstrated a limit of quantitation at 0.0005 mg/kg, with correlation coefficients exceeding 0.999 across the 0.0005-0.05 mg/kg concentration spectrum. In four different sources of chives and two leafy vegetables, the matrix effects were found to be inconsequential, varying from -188% to 72%.
