Initially, the total phenolic content (TPC), flavonoid content (TFC), anthocyanin content (TAC), and antioxidant activity (AA) of <i>C. asiatica</i>’s leaf and stem were examined. Subsequently, chicken nuggets were formulated with varying amounts of Thankuni extracts to evaluate their impact on proximate composition as well as their shelf life. Combinations of leaf and stem extracts of <i>C. asiatica</i> exhibited the highest TPC of 24.215 mg GAE/100 g and TFC of 104.358 mg QE/100 g compared to using either stem or leaf alone. Notably, the leaf extract demonstrated the highest TAC of 19.548 mg TA/100 g, while the stem extract displayed the highest AA of 18.027%. The methanolic extract showed substantial inhibition zones against <i>Salmonella</i> and <i>Escherichia coli</i>, whereas both aqueous and methanolic extracts showed no response against <i>Staphylococcus aureus</i>. Furthermore, the study analyzed the nutritional composition of chicken nuggets, finding variations in moisture, crude protein, fat, ash, and carbohydrate contents. Over time, there was a gradual decline in phytochemical contents and AA, although chicken nuggets containing a substantial amount of <i>C. asiatica</i> extract exhibited this decline more slowly compared to the control. Higher TPC value (2.391 mg GAE/100 g) was obtained in samples containing 2% Thankuni leaves and stem extract on the zeroth day, while the control samples without any <i>C. asiatica</i> addition showed minimum TPC values (0.649 GAE/100 g) by the 21st day of storage. Similar trends were also noted for TFC and AA.

The findings revealed that fresh-cut strawberries exhibited higher maximum respiration rates (<i>V</i>_<i>m</i>) than dragon fruit, with the fermentation threshold occurring at 51 h for strawberries and 156 h for dragon fruit. Specifically, the critical O₂ and CO₂ concentrations for strawberries were 2.89% O₂ and 13.91% CO₂, while for dragon fruits, they were 5.22% O₂ and 11.01% CO₂. This study is novel in its use of uncompetitive inhibition enzyme kinetics to model gas concentration effects and provide new insights into the respiration characteristics of fresh-cut strawberries and dragon fruits under storage. The results offer a theoretical foundation for optimizing MAP conditions, thus improving storage strategies, enhancing fruit quality, and extending shelf life.

Thereafter, the phenolic profile was analyzed with high-performance liquid chromatography (HPLC), followed by the determination of the antioxidative effects of the <i>S. retroflexum</i> leaf extracts in salad dressing. The TFC and TPC of the <i>S. retroflexum</i> leaf extracts were 575.35 mg quercetin equivalents/g (dw) and 130.00 mg gallic acid equivalents/g (dw), respectively. The antioxidant activity was 1054.39 <i>μ</i>M Trolox equivalents/g (dw) (ABTS) and 176.77 <i>μ</i>M Fe equivalents/g (dw) (FRAP). Phenolic compounds identified with HPLC included protocatechuate, ellagic acid, and 4-hydroxycinnamic acid. All the extracts of <i>S. retroflexum</i> retarded hydrolysis of fat in salad dressing under accelerated Schaal oven test conditions, that is, as effective as butylated hydroxy anisole. In addition, <i>S. retroflexum</i> leaf extracts, when present at 300 mg/mL, slightly delayed peroxide formation in salad dressing perhaps owing to their high polar plant phenolic concentration.

Contrarily, despite growing interest in fermentative applications, haskap wine studies are extremely limited. Due to the high pigmentation of haskap juice, a fermentation experiment with different prefermentative juice dilutions was conducted to discover the influence of dilution on haskap wine fermentation and final wines. Four treatments, including 1:1, 1:2, 1:4, and 1:5 juice-to-water ratios, were applied in this research. The results indicated that water quantities for dilution may influence the fermentation completion rate. Concerning final wines, the 1:1 dilution ratio had significantly lower pH and lower ethanol but higher acidity and glycerol compared to the other three treatments. With increasing dilution, the final wine color variation increased relative to the initial must color. Antioxidant activities in the final wines were all reduced compared with the corresponding initial must metrics. The total phenolic profiles indicated dilution largely influenced total anthocyanins followed by total flavonols while having limited influence on the total hydroxycinnamates and total flavanols in haskap wines. With anthocyanin compounds as the main coloring components detected in haskap wines, future research may focus on haskap nutrients and quality maintenance during primary fermentation and throughout aging processes.

A total astaxanthin content of 168 mg/g of freeze-dried biomass was obtained. The extract was incorporated in different food matrix systems to identify the most suitable form for food formulations. Astaxanthin showed the best stability during storage when incorporated into nonacidified milk. Similarly, it exhibited better stability when incorporated into strong gels. Specifically, when 0.1 mg/g was incorporated in food gels of different strengths, 0.07 mg/g of astaxanthin was detected after 96 h of storage in the strong gel, compared to only 0.058 mg/g in the weaker gel. Moreover, thermal stability was evident during heat treatments encountered in food processing, such as pasteurization (65°C for 30 min and 72°C for 15), ensuring that the extract or the biomass can be incorporated into food formulations that require brief exposure to thermal energy without losing its health benefit. Finally, incorporation into an emulsion system stabilized with three cycles of sonication retained the DPPH activity, likely due to the better physical stability achieved with smaller emulsion droplets obtained during higher cycles of sonication.
