The sole microwave heating and conventional heating were also performed at the same temperature levels, and effectiveness of three different treatments were evaluated. The required treatment times were decided based on obtaining <10% pectin methylesterase (PME) activity, and ultrasound pretreatment provided the least heating durations. Turbidity, browning index, and viscosity values increased by 3.4 to 14.8-fold, 0.24 to 1.26-fold, and 9.2% to 48.0%, respectively, after all thermal treatments, while Brix values decreased by 1.4% to 15.7%. Ultrasound pretreatment revealed relatively lower browning index in all temperature levels, and almost the highest viscosity values were obtained in sonication pretreated microwave heating as compared with sole microwave and conventional heating. The minimum turbidity value (0.035) was determined in ultrasound-assisted microwave heating at 60 °C. The highest antioxidant capacity (DPPH and ABTS) values were achieved by ultrasound-assisted microwave heating (up to 4.96 and 28.4 mmol Trolox equivalent (TE)/kg, respectively) followed by microwave heating (up to 4.30 and 27.0 mmol TE/kg) and conventional heating (up to 3.72 and 26.8 mmol TE/kg).

While the non-irradiated sample revealed the highest level of HMF and bacterial growth.

A 30 min plasma treatment resulted in a pronounced decrease in the concentration of flavan-3-ols, which play a pivotal role in antioxidant defense and browning prevention. This significant reduction is likely due to plasma-induced oxidative stress, which can lead to the breakdown of these compounds or their conversion into other phenolic structures. Simultaneously, a slight increase in dihydrochalcones and flavonols was observed, suggesting a selective effect of plasma on different phenolic classes. The increase in these compounds could be attributed to the plasma's ability to induce specific reactions that generate these phenolics from other precursors present in the apples. The reduction in flavan-3-ols may affect the antioxidant capacity and health benefits associated with the apples, while the increase in dihydrochalcones and flavonols could have a positive impact on the flavor profile and potential health-promoting properties.

The objective of this study was to develop natural spices and herbal tea with health beneficial properties using <i>Solanum nigrum</i> and <i>Solanum torvum</i> berries. Herbal tea samples from <i>S. nigrum</i> were prepared by sorting berries, maceration, divided into two (fermenting at 18 °C and non-fermenting) and dried at 60 °C for 12 h in a hot oven. Spices from <i>S. torvum</i> and <i>S. nigrum</i> were prepared by removing the berries from the stalk, freeze-drying and smooth milling into fine powder. In addition, antinutrient, phytochemical and sensory evaluation studies were conducted on these spices and herbal teas. A nine-point hedonic scale was utilized for the purpose of conducting a consumer acceptability sensory evaluation test using 101 untrained panelists. Data was then analyzed by t-test, one-way analysis of variance (ANOVA) and the level of significance (p < 0.05) was assessed using Tukey's and Dunnett's multiple comparison tests. The panellists expressed a favourable perception towards <i>Solanum nigrum</i> unripe unfermented green herbal tea (6.65 ± 2.08) as compared to the other formulated teas due to the components working together in a way that produces a nice tea sample. Both <i>Solanum nigrum</i> and <i>Solanum torvum</i> spices contained various levels of catechins, saponins, flavonoids, oxalates, phytates and tannins comparable to literature. The herbal tea samples exhibited a range of catechin content, varying from 0.255 to 0.756 mg/g.

This study aims to maximize the utilization of corn silk by evaluating its phytochemical, physicochemical and sensory characteristics. The development of food products with enhanced nutritional value is a pressing concern for both scientists and food producers in the industry. Therefore, this research focuses on the creation of highly nutritious muffins incorporating underutilized corn silk powder (CSP). In the muffin preparation, CSP was used to partially replace refined wheat flour at levels of 10%, 20%, 30% and 40%. As the proportion of CSP increased, the protein and crude fiber content of the muffins gradually increased. Additionally, the total phenolic content and antioxidant activity of the muffins significantly increased (p ≤ 0.05) with the inclusion of CSP, reaching their maximum values when CSP was used to replace 40% of the refined wheat flour. The incorporation of CSP led to a decrease in the L* (lightness) value, resulting in lower a* (redness) and b* (yellowness) values in the muffins. Texture analysis revealed that the cohesiveness, chewiness and gumminess of the muffins increased as the amount of CSP in the recipe was raised. A sensory evaluation was conducted to assess the acceptability of the corn silk muffins. The addition of CSP in muffins improved the sensory characteristics including colour, aroma, mouthfeel, texture and overall acceptability.
