The yellow mealworm, Tenebrio molitor, has risen in popularity amidst the growing interest in ideally sustainable alternative protein sources. To evaluate the potential of T. molitor larvae as a safe and healthful food source, examining their microbiome is essential. This study's subsequent focus was twofold: firstly, examining how the substrate affects the microbial content of larval microbiomes; secondly, identifying processing methods guaranteeing safe mealworm consumption. To achieve this, mealworms were cultivated on ten diverse substrates, including by-products from food production, such as malt residual pellets, corn germ meal, chestnut breakage and meal, wheat bran, bread scraps, draff, nettle, hemp seed oil cake, oyster mushrooms with coffee grounds, and pumpkin seed oil cake. Subsequently, microbial loads within the samples were evaluated using various selective media. To study how starvation/defecation and heating (850 W for 10 minutes) contribute to the reduction of microbial populations, these methods were applied. The mealworm's characteristics demonstrated no substantial association with the microbial concentration in the substrate, based on the study's outcomes. Defecation and starvation combined to trigger a reduction in the number of microorganisms present. A significant reduction in microbial life was achieved in mealworms that had not defecated, by means of heating. Despite defecation and heating, the mealworm group exhibited no quantifiable microbial load. Concluding, firstly, the substrate choice had no effect on the bacterial count of Tenebrio molitor larvae; secondly, applying heat and withholding food guarantees safe consumption. This study importantly contributes to the evaluation of mealworm safety as a sustainable protein source in the context of human nutrition.

Designing healthier lipids is a prevalent approach within the ongoing quest for novel functional foods. Olive pomace oil's (OPO) positive impact on human health stems from its high oleic acid content and special bioactive components. Four puff pastry margarines (PP-Ms) were created using OPO (M1, M2 at 408%, M3, M4 at 308%, and 10% cocoa butter), combined with low molecular weight organogelators. These were then subjected to two different initial cooling rates (0.144 °C/min for M1 and M3, and 0.380 °C/min for M2 and M4), and their performance was contrasted against commercial puff pastry butter (CB) and a fatty preparation (CFP). Afterwards, six variations of baked PP counterparts were constructed. A study of M1-M4 and PP samples included physical-chemical, mechanical, and lipid profile examinations; thermal characteristics were, in contrast, evaluated in M1-M4 alone. Sensory analysis was carried out to evaluate the PP-M1 and PP-M3 counterparts. Despite exhibiting elasticity (G') values within the same range as controls CB and CFP, M1-M4 samples with higher OPO content showed a lower viscous modulus (G). Despite variations in the initial cooling rate, the melting behavior of M1-M4 remained consistent. The PP-M1's firmness mirrored that of PP-CB and PP-CFP, and its superior spreadability and plasticity were instrumental in enhancing PP puffing performance. PP-M1 displayed 368% lower SFA levels when compared to baked PP-CB, but their overall acceptability remained comparable. A groundbreaking margarine, composed of a high percentage of OPO, successfully demonstrated adequate firmness, spreadability, and plasticity, ultimately producing a PP with appropriate performance and sensory attributes, coupled with a wholesome lipid profile, a first.

Employing chemometrics and IR spectroscopy, Southern Romanian honey varieties, including multifloral, sunflower, linden, rapeseed, and acacia, were categorized. The research aimed to unveil the relationship between botanical origin and the physicochemical qualities of honey, ultimately highlighting the most valuable plant source. Except for antioxidant activity, the botanical origin of the honey significantly varied the moisture, ash, electrical conductivity (EC), pH, free acidity (FA), total sugar content (TSC), hydroxymethylfurfural (HMF), total phenolic (TPC), tannin (TTC), and flavonoid content (TFC). In comparison to multifloral honey's notable total sugar content of (6964 g Glu 100 g-1), sunflower honey demonstrated higher levels of moisture (1553%), free acidity (1667 mEq kg-1), electrical conductivity (48392 S cm-1), phenolics (16759 mg GAE 100 g-1), and flavonoids (1900 mg CE 100 g-1). A remarkable 3394 mg kg-1 of HMF was detected in the linden honey sample. The HMF levels in each honey sample analyzed fell within the established standard, demonstrating the absence of any heat treatment in the examined honey. gastrointestinal infection Concerning storage and consumption, the five tested honey varieties exhibited moisture content that satisfied the safety criteria, ranging from 1221% to 1874%. The freshness of the tested honey samples and their freedom from fermentation were apparent, as indicated by the free acidity range of 400 to 2500 mEq kg-1. Nectar-derived honey displayed the specific qualities present in honey exceeding a sugar concentration of 60%, with the notable exclusion of linden honey which has a glucose content of 58.05 grams per 100 grams. The moisture, flavonoids, and HMF of honey demonstrated a positive association with the increased antioxidant activity of honey, whereas tannins and HMF showed a positive correlation with ash and electrical conductivity levels. The abundance of phenolics, flavonoids, and tannins was positively associated with elevated levels of free acidity. Linden honey was clearly differentiated from acacia, multifloral, and sunflower honeys by the use of ATR-FTIR spectra in conjunction with chemometric analysis.

The impact of heat treatment on the flavor attributes of highland barley flour (HBF) over time was determined by examining the changes in volatile compounds, using GC-MS and relative odor activity values (ROAVs), for flavor deterioration analysis. Untreated and extrusion-puffed HBFs predominantly contained hydrocarbons, whereas explosion-puffed, baked, and fried HBFs were largely composed of heterocycles. Among the factors contributing to the deterioration of flavor profiles in different HBFs, hexanal, hexanoic acid, 2-pentylfuran, 1-pentanol, pentanal, 1-octen-3-ol, octanal, 2-butyl-2-octanal, and (E,E)-24-decadienal stood out. The major production routes for amino acids and fatty acids were determined to correlate with their respective metabolic transformations. Baking slowed the deterioration of flavor in HBF, while extrusion puffing augmented the rate of flavor degradation in the same HBF product. Quality evaluation of HBF was possible due to the screening and analysis of pertinent key compounds. This research provides a theoretical foundation for governing the taste and aroma of barley and its resulting products.

In our study, we successfully isolated and identified the transcription factor Cmr1 from the fungus Aureobasidium pullulans Hit-lcy3T, which directly controls melanin biosynthesis gene expression. Bioinformatics investigation of the Cmr1 gene uncovered a protein sequence of 945 amino acids, encompassing two Cys2His2 zinc finger domains and a Zn(II)2Cys6 binuclear cluster domain strategically positioned at the N-terminus. To probe the function of the Cmr1 gene, we performed experiments involving gene knockout and overexpression. Our findings indicate that Cmr1 plays a critical role in melanin production within Hit-lcy3T cells, and its lack of presence led to developmental abnormalities. Conversely, the overexpression of Cmr1 exhibited a considerable increase in chlamydospore production in Hit-lcy3T strains, resulting in improved melanin formation. RT-qPCR analysis subsequently indicated that elevated Cmr1 expression spurred the expression of multiple genes critical to melanin production, encompassing Cmr1, PKS, SCD1, and THR1. Characterization of the melanin extracted from Hit-lcy3T was conducted using UV and IR spectroscopy. Finally, we characterized the antioxidant properties of Hit-lcy3T melanin, revealing potent scavenging activity against DPPH, ABTS, and hydroxyl radicals; surprisingly, the scavenging activity against superoxide radicals was comparatively weaker. These discoveries about Hit-lcy3T melanin suggest its potential to be a valuable functional food additive in the future.
