The optimized condition, as modeled by RSM, yielded predicted values of 322% extraction yield, 99 mg GAE per gram of TPC, 68 mg QE per gram of TFC, and 58% antioxidant activity for the target compounds. The leaf extracts’ optimized condition, according to the ANN-GA model, was found to be 60% amplitude, a 13-minute treatment, and a 53% ethanol concentration. The ANN-GA model’s analysis of optimized conditions yielded a prediction for the extraction yield of 321738%, and values of 98661 mg GAE/g, 68398 mg QE/g, and 585527% for TPC, TFC, and antioxidant activity, respectively. Unharvested mature garlic leaves, during the cultivation process, often represent a lost opportunity, even though they boast substantial levels of antioxidants and phenolic compounds. The escalating need for value-added goods necessitates extracting bioactive compounds from garlic leaves, which addresses waste management and potential health concerns without diminishing crop yields. This process facilitates high-end utilization in value-added applications.
Spray drying (SD) presents a potential solution for enhancing the utility of laurel (Laurus nobilis L.) leaves in functional foods. The leaves, rich in polyphenols, face the challenge of low stability and bioavailability, hindering their incorporation. The influence of SD parameters, encompassing inlet temperature (120, 150, and 180 degrees Celsius), carrier type (β-cyclodextrin (-CD); β-cyclodextrin + maltodextrin (MD) 50/50; β-cyclodextrin + gum arabic (GA) 50/50), and sample-to-carrier ratio (11, 12, and 13), on the physicochemical properties, encapsulation efficiency, polyphenolic profile, antioxidant capacity, and bioaccessibility of laurel leaf polyphenols was investigated in this research. The application of either carrier resulted in the maximum encapsulation efficiency at a sample-carrier ratio of 12 and a temperature of 180 degrees Celsius. The -CD + MD 5050 formulation, while achieving optimal solubility (5510%), hygroscopicity (1532%), and antioxidant capacity (ORAC 15792 mol Trolox equivalents per gram of powder), required temperatures exceeding 150°C to achieve the optimal moisture content (322%). SD encapsulation demonstrably improved laurel flavonol bioaccessibility, showing a roughly 50% enhancement in the gastric phase and a roughly 10% enhancement in the intestinal phase, particularly for powders created with carrier mixtures, compared to the non-encapsulated extract.
The burgeoning global population presents a significant challenge in food science, requiring solutions that overcome environmental constraints, including climate change, water scarcity, land degradation, marine pollution, and desertification. The problem of food waste can be effectively addressed by preventing the spoilage of edible food and using nutritious by-products as food, instead of using them as animal feed; this is both simple and powerful. A substantial portion of the global population relies on rice as a vital food staple, and this rice grain milling process results in a substantial amount of rice bran as its primary byproduct. Usually, rice bran is either incorporated into animal feed formulations or is discarded as waste product. Although rice bran is exceptionally nutritious and contains many bioactive compounds that offer substantial health improvements, the quick deterioration of the bran restricts the achievement of its full potential utilization. The primary hurdle to employing rice bran as nourishment is its susceptibility to hydrolytic rancidity, which can only be circumvented through the enzyme inactivation method, otherwise known as stabilization. This study examines the techniques for stabilizing rice bran and other rice milling byproducts, specifically focusing on rice bran, while considering the storage efficiency of the process. The rice bran components’ responses to the process are also examined.
Purple Chinese Cabbage (PCC)’s compelling purple coloration and significant nutritional benefits, arising from its rich anthocyanidin content, have made it a prominent focus in modern breeding. To expedite the evaluation of PCC anthocyanidin levels and the selection of high-performing breeding materials, a quantitative detection method utilizing Near Infrared Spectroscopy (NIR) for anthocyanidins within PCC was established. Processing NIR spectral data from PCC samples, in tandem with chemometric results of anthocyanidin content determined via high-performance liquid chromatography, enabled the creation of the prediction models. Cyanidin content in PCC ranged from 935 mg/kg to 12802.4 mg/kg, significantly exceeding the concentrations of other anthocyanidins. NIR prediction models for cyanidin, developed with partial least squares regression and preprocessing with no-scattering mode and first-order derivative, demonstrated exceptional performance. The calibration set’s external correlation coefficient (RSQ) was 0.965 and standard error of cross-validation (SECV) was 693.004. Total anthocyanidins showed an RSQ of 0.966 and an SECV of 685.994 in the calibration set. The established models proved effective, and the NIR method, which offered time-saving and convenient features, made it applicable in the practical breeding of purple vegetables.
The cooking, concentration, and spray drying of Taiwanese tilapia (Oreochromis mossambicus) offcuts resulted in a unique umami-rich seasoning powder high in glutamic acid (023 mg/100 g), glycine (010 mg/100 g), aspartic acid (011 mg/100 g), lysine (010 mg/100 g), and additionally containing 11 other amino acids. The spherical powder microstructure exhibited impressive characteristics, including water content (381%), water activity (0.3), substantial powder yields (6883%), and a high water solubility index (9989%). Its consumer-type sensory evaluation showcased a superior preference score of 753, exceeding all commercially available seasonings. The current study supports the notion that, upon suitable processing, offcuts can become a part of the human diet, and their extensive application in savory cuisine is confirmed. Environmental stewardship and financial prosperity are achievable goals for the involved producers. Through practical contributions and an operational guide for transitioning from inefficient to innovative circular practices, critical stakeholders in the tilapia supply chain can experience incremental value at each stage.
Diverse investigations have provided supporting evidence for the advantageous impact of both prebiotics and probiotics on the gut microflora. Prebiotic and bioactive compound use as energy and carbon sources is crucial for selectively supporting beneficial bacterial growth, promoting a healthy gut microbiota. The current research project aimed to determine the fermentability of tomato flour produced from ohmic (SFOH) and conventional (SFCONV) methods of phenolic compounds and carotenoids extraction, along with examining its influence on particular microbial communities. The bagasse flour, obtained through the process, underwent an in vitro simulation of gastrointestinal digestion, with its subsequent fermentability and effect on gut microbiota evaluated using an in vitro fecal fermentation model. The probiotic strains exhibited different outcomes when exposed to various conditions; SFCONV stimulated growth of B. animalis, while SFOH stimulated the growth of B. longum, conceivably due to the contrasting carbohydrate compositions in the flours. In general, the flours employed were effective as a direct substrate for facilitating the potential prebiotic growth of Bifidus longum. The fecal fermentation model’s output exhibited the greatest Bacteroidetes expansion with SFOH, and the highest Bacteroides concentrations were seen with SFCONV. It was also determined that the growth of microorganisms is associated with short-chain fatty acids. This byproduct exhibits the capacity to promote a favorable influence on the microbial community, potentially qualifying it as a prebiotic, though additional in-vivo research is vital for verification.
Heavy metals, a category of toxic substances, have been recognized by humanity for a considerable duration. Today, owing to the multitude of exposure pathways, including contaminated water, food, and air, they have become a significant public health concern. This research highlights the influence of Cd2+, Cr6+, and Pb2+ at varying concentrations in water, casein, and milk matrices on infrared spectral behavior, demonstrating changes in the vibrational modes of -OH, COO-, and NH2 nucleophilic groups. In-silico correlation of these findings, employing optimized Gabedit models, revealed stable structures between the metals and the Gln, Hys, Glu, and Phe residues of casein, a conclusion supported by structural optimization using MOPAC 2016. The application of Principal Component Analysis within chemometrics enabled a clear correlation between experimental data and the characterization of metal types, their matrices, and their concentrations. Linear models effectively represented these relationships and showed a high degree of adjustment, indicated by an R-squared value of 0.95.
An examination of biofilm formation by different Salmonella strains on prevalent processing plant surfaces (stainless steel, concrete, rubber, and polyethylene) was conducted under static and dynamic shear stress regimes. For 48 hours, surface-coupons were submerged in 1 mL well-plates containing Salmonella (6 log CFU/mL) and incubated aerobically at 37°C, either statically or under shear stress. The crystal violet assay facilitated the determination of biofilm density, and the number of biofilm cells was established by streaking them onto tryptic soy agar plates. fak signal Using scanning electron microscopy, the biofilms were made visible. The data were analyzed using SAS 9.4, having a significance level of 0.05. A statistically significant (p<0.0001) association was found between biofilm density and surface incubation conditions. Stainless steel specimens subjected to shear stress resulted in a greater OD600 measurement than their statically incubated counterparts; in contrast, polyethylene samples displayed a higher OD600 under static conditions. Enumeration data highlighted a significant interplay between the surface-incubation condition (p = 0.0024) and the surface-strain (p < 0.0001).
