The burgeoning interest in microbial proteins stems from the rising demand for affordable, wholesome, and eco-friendly alternative protein sources. The prevalence of mycoproteins is attributed to their well-rounded amino acid profile, their reduced carbon footprint, and their considerable sustainability potential. The objective of this research was to investigate Pleurotus ostreatus's metabolic efficiency in converting the predominant sugars from agro-industrial by-products, like aspen wood chips hydrolysate, to produce low-cost high-value protein. The mycoprotein production capabilities of P. ostreatus LGAM 1123 are supported by our results, which show cultivation is feasible in media containing C-6 (glucose) and C-5 (xylose). Biomass production reached optimal levels with the combination of glucose and xylose, resulting in high protein content and a profile rich in amino acids. Affinity biosensors Using a 4-liter stirred-tank bioreactor fed with aspen hydrolysate, the cultivation of *P. ostreatus* LGAM 1123 achieved a biomass production of 250.34 grams per liter, a specific growth rate of 0.1804 per day, and a protein yield of 54.505 percent (grams per 100 grams of sugars). The amino acid makeup of the resultant protein, as ascertained by PCA analysis, showed a strong association with the glucose and xylose concentration ratio in the culture medium. Employing agro-industrial hydrolysates for submerged fermentation, the production of high-nutrient mycoprotein from the edible fungus P. ostreatus offers a promising avenue within the food and feed industry.
Salting milk before the coagulation phase is a method of salting employed in the production of Domiati-type cheeses and certain types of Licki Skripavac cheese. When seeking a sodium replacement, potassium is the most common choice. An investigation into the impact of various salt concentrations (1%, 15%, and 2%) and NaCl to KCl ratios (100%, 50:50%, and 25:75%) on the rennet coagulation process and the resulting curd firmness of bovine milk was conducted. With the aid of the Lactodinamograph, a computerized renneting meter, the parameters of milk coagulation were determined. A statistically significant (p < 0.005) interaction was observed in the results, stemming from the combined effects of salt concentrations and the NaCl to KCl ratio. Future studies should utilize these outcomes to develop consumer-friendly, low-sodium products that do not sacrifice product quality.
Human dietary practices frequently neglect proso millet (Panicum miliaceum), a valuable crop. Due to the unique composition of its grains, millet is a suitable food for individuals with celiac disease, and it also contributes to the prevention of cardiovascular ailments. For the purpose of GC-MS analysis encompassing all millet plant parts, the Hanacka Mana and Unicum varieties were selected. In the roots, leaves, stems, and seeds, substances such as saccharides, amino acids, fatty acids, carboxylic acids, phytosterols, and more were discovered. Stems displayed the largest saccharide quantity (83%); roots had the highest amino acid concentration (69%); seeds contained the highest fatty acid content (246%); carboxylic acids were present at the lowest levels in roots (3%); seeds had a significant quantity of phytosterols (1051%); leaves contained various compounds including tetramethyl-2-hexadecenol (184%) and tocopherols (215%); roots held retinal (130%), and seeds had squalene (129%). Within every part of the proso millet plant, saccharides were the predominant group, and fatty acids were the next most common. Sucrose, fructose, and psicose constituted the primary saccharide components within the complete millet plant. Notwithstanding, turanose, trehalose, glucose, and cellobiose displayed the lowest representation in the examined sugar sample. In addition, amyrin, miliacin, campesterol, stigmasterol, beta-sitosterol, and various other substances were found. Varietal variability, for instance, in retinal, miliacin, or amyrin content, can be anticipated.
Waxes, phospholipids, free fatty acids, peroxides, aldehydes, soap, trace metals, and moisture in crude sunflower oil diminish its quality, compelling their removal during refinement. Cooling and filtration during winterization procedures eliminate waxes that crystallize under low-temperature conditions. In industrial settings, the filtration of waxes is frequently problematic due to their poor filtration properties. To address this, filtration aids are employed, improving the structure and quality of the filter cake, thereby increasing the duration of the filtration cycle. In the industry, traditional filtration aids, such as diatomite and perlite, are often superseded by cellulose-based alternatives. The effect of oil filtration, augmented by two cellulose-based filtration aids, on the chemical parameters (wax, moisture, phospholipids, soaps, and fatty acids), visual transparency, carotenoid content, and iron and copper levels in sunflower oil extracted from an industrial horizontal pressure leaf filter is the focal point of this investigation. The following methodologies were used for assessing the given parameters: gravimetric analysis (wax and moisture content), spectrophotometric analysis (phospholipid and carotenoid content and oil transparency), volumetric techniques (soap and free fatty acid content), and inductively coupled plasma mass spectrometry (ICP-MS) for determination of iron and copper content. Based on the chemical properties, visual clarity, and iron and copper content of the oil before filtration, along with the amount of filtration aid and the filtration time, an artificial neural network (ANN) model was applied to estimate the removal efficiency. Cellulose-based filtration aids exhibited demonstrably positive results, boasting an average removal rate of 9920% for waxes, 7488% for phospholipids, 100% for soap, 799% for carotenoids, 1639% for iron, and 1833% for copper.
This investigation sought to identify the presence of phenolics, flavonoids, and tannins within propolis extracts, alongside analyzing the biological functions of these extracts, derived from the stingless bee species Heterotrigona itama. Raw propolis was extracted by maceration, which was enhanced by ultrasonic pretreatment in a solvent mixture of 100% water and 20% ethanol. A 1% difference was observed between the yield of ethanolic propolis extracts and their aqueous equivalents. According to colorimetric assays, the ethanolic propolis extract displayed significantly elevated levels of phenolics (17043 mg GAE/g), tannins (5411 mg GAE/g), and flavonoids (083 mg QE/g), exhibiting approximately a twofold increase in the former two and a fourfold increase in the latter. The ethanolic extract's antiradical and antibacterial effectiveness were boosted by the elevated level of phenolic compounds. The propolis extracts showed a more pronounced antibacterial effect on gram-positive bacteria (Staphylococcus aureus) than they did on gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa). Although alternative extracts were investigated, the aqueous extract demonstrated superior anticancer properties, as measured by lung cancer cell viability. Despite increasing the concentration of propolis extracts to 800 g/mL, no cytotoxic effect was observed on normal lung cells, with cell viability consistently exceeding 50%. nasal histopathology The distinct chemical profiles of propolis extracts exhibit diverse bioactivities based on the specific applications employed. Due to the high concentration of phenolics, propolis extract is suggested to be a natural source of bioactive ingredients, contributing to the development of cutting-edge and functional food products.
Canned Atlantic mackerel (Scomber scombrus), following six months of frozen storage (-18°C) and diverse coating applications (water, brine, and sunflower, refined olive, and extra-virgin olive oils), were analyzed to determine the alterations in essential macroelement and trace element content. learn more Frozen storage prior to canning significantly (p < 0.005) elevated the amounts of potassium (oil-coated) and calcium (across all coatings) in the preserved samples, but conversely reduced the quantities of phosphorus (aqueous coating) and sulfur (water and oil coatings). Analysis of canned fish muscle preserved via frozen storage revealed a statistically significant (p < 0.005) rise in copper and selenium content (in brine-canned samples) and manganese content (in water- and refined-olive-oil-coated samples) with respect to trace elements. The coating application method, specifically water-based coatings, resulted in significantly lower (p < 0.05) levels of magnesium, phosphorus, sulfur, potassium, and calcium compared to the oil-coated specimens. In aqueous-coated fish muscle, the average concentrations of cobalt, copper, manganese, selenium, and iron were observed to be lower compared to their oily-coated counterparts. Processing of canned fish muscle and associated tissue interactions give rise to changes in the content of the muscle elements. These changes are notably related to protein denaturation, loss of fluids from the muscle, and adjustments in the lipid profile.
For those experiencing difficulties swallowing, a dysphagia diet is a customized approach to eating. Dysphagia food development and design must prioritize the dual aspects of swallowing safety and nutritional value. This study scrutinized the impact of four nutritional supplements – vitamins, minerals, salt, and sugar – on swallowing characteristics, rheological and textural attributes. Subsequently, a sensory evaluation was performed on dysphagia foods comprising rice starch, perilla seed oil, and whey isolate protein.
