However, the lack of self-sufficiency of local pig producers means the Slovenian pork industry relies on sourcing raw materials (green hams) from foreign countries. This study is aimed at investigating the impact of different weights (16 heavy and 16 light) and suppliers on product quality by analysing 32 samples of dry-cured ham for quality attributes, including colour, texture, chemical composition, descriptive sensory characteristics (such as flavour and texture) and aroma profile. Analyses were conducted on the semimembranosus and biceps femoris muscles, and multivariate statistical methods, including linear discriminant analysis (LDA) and orthogonal partial least squares–discriminant analysis (OPLS-DA), were applied to differentiate between heavy and light hams (based on initial weight categories) and suppliers. Sensory analysis revealed higher softness, juiciness, solubility, marbling and lower saltiness in heavy than in light hams. The SI_heavy hams have received the highest ratings for overall sensory quality. The comparison of volatile organic compound (VOC) profiles indicated the potential for differentiating dry-cured ham by suppliers, particularly within the heavy ham groups, achieving 100% prediction accuracy. Notably, the biceps femoris muscle generally exhibited a higher intensity of positive sensory attributes, such as juiciness, solubility and softness, compared to the <i>s</i>emimembranosus, which tended to be firmer and less marbled.

Among the various medicinal plants, <i>Withania somnifera</i> (commonly known as ashwagandha) has gained significant attention in this regard due to its potential health benefits. Despite its well-documented therapeutic properties, its application in staple food formulations remains limited. This study is aimed at exploring the incorporation of ultrasound-assisted dried <i>W. somnifera</i> leaf, seed, and stem flour into wheat flour for the development of flat unleavened bread, which is the most consumed food product worldwide. Proximate analysis revealed that the leaves of <i>W. somnifera</i> had the highest moisture (24.64%) and ash (3.09%), while the seeds exhibited the highest fat (13.86%) and protein (5.01%). In contrast, the stems were rich in fiber (11.43%) and carbohydrates (60.71%). Mineral analysis showed that the leaves contained the highest calcium content, the seeds were rich in sodium, and the stems had the highest magnesium and potassium. Wheat flour was partially replaced with finely dried flour of the leaves, seeds, and stems of <i>W. somnifera</i> at varying concentrations (2%, 3%, 4%, and 5%). The supplemented flours were evaluated for their functional properties, including bulk density, water and oil absorption capacities, foaming activity and stability, and emulsification activity and stability. In addition, the effects of <i>W. somnifera</i> flour incorporation on dough rheology and the color and sensory characteristics of the final bread were assessed to determine their influence on processing behavior and overall acceptability. Significant variations were observed across all parameters due to the interaction between <i>W. somnifera</i> parts flour and wheat flour. The results indicated that moderate supplementation, particularly at the 2% level, offers an optimal balance of improved functional properties, dough rheology, and color and sensory attributes in flat unleavened breads.

This study seeks to explore how 528 Hz influences the physical and chemical characteristics as well as the microbial viability of yogurt, a dairy product containing active cell cultures. During a 31-day storage period, various yogurt samples were subjected to either 528-Hz sound, city noise (a continuous day-time recording from a crowded urban area), or kept under standard conditions for comparison. The main goal was to evaluate changes in pH levels, moisture separation (syneresis), sensory properties like taste and texture, consistency, flow behavior, and the survival of <i>Streptococcus thermophilus</i> bacteria. The findings indicated that the pH values of yogurt exposed to 528 Hz remained relatively stable throughout the storage period, only experiencing a slight decrease from 4.33 to 4.25 by Day 31. In contrast, the control group showed a more pronounced reduction from 4.33 to 4.10 during the same period. Assessment of taste perception, texture quality, and aroma intensity revealed higher scores for samples treated with 528 Hz compared to those in the control group. <i>S. thermophilus</i> counts, for all samples, initially experienced a decline but showed recovery by Day 31, with final counts ranging from approximately 4.42 × 10⁷ to about 4.7 × 10⁷ CFU/mL. To sum up, the use of the 528-Hz sound frequency had a beneficial impact on the sensory characteristics and pH stability of yogurt while not causing notable changes in syneresis, texture, or microbial viability.

Glutathione, a tripeptide antioxidant, effectively inhibits polyphenol oxidase (PPO) through its unique structure and multifaceted antioxidative mechanisms. Hypotaurine, a cysteine derivative, has also shown success in mitigating enzymatic browning across various food categories. Therefore, both compounds demonstrate key advantages over sulphites and nonsulphite alternatives, including improved safety profiles, reduced toxicity and enhanced versatility across complex food matrices.

This study compares the effects of magnetized water and magnetic field exposure with those of untreated water (control) on the quality of sprouted quinoa powder.
