The potential health impacts of moderate alcohol consumption have long been debated. The COVID-19 pandemic has heightened public awareness of health concerns, creating a clear market opportunity for low-alcohol craft beer development. This study investigated the possibility of low-alcohol craft beer by co-fermentation with different ratios of Pichia kluyveri (P. kluyveri) and Saccharomyces cerevisiae (SC) according to the established quality indexes. Specifically, this study was conducted to identify the low-alcohol craft beer quality by fermentation kinetics, growth kinetics, apparent attenuation (AA), real attenuation (RA), residual sugar content, alcohol by volume (ABV), and volatile organic compounds. This study demonstrated that the co-fermentation of SC and P. kluyveri in a 1:10 ratio produced an ABV of 2.98% (v/v). In addition, high concentrations of isoamyl acetate and phenyl ethyl acetate revealed banana, rose, apple, and honey flavors, respectively. Overall, this study revealed that the fermentation of P. kluyveri and SC by co-fermentation and the fermentation process by adjusting the yeast composition developed a craft beer with low alcohol content and rich aroma while establishing the quality indicators.

This study investigated the potential of enhancing edible film (EF) formulations by incorporating Premna microphylla Turcz leaf (PM) water extracts (PMWE) and glycerol as plasticizers. Incorporating 75 % PMWE and 5 % glycerol significantly improved the physicochemical and mechanical properties of the films while effectively preserving the quality indicators and extending the shelf-life of cherry tomatoes (CT; Lycopersicon esculentum Mill) in film and coating applications. The PMWE-based films and coatings reduced decay rates (from 80 to 36–52 %) and exhibited a statistically significant difference (p < 0.05) compared to the control group. These findings highlight the potential of PMWE as an effective ingredient in EF formulations, capable of extending shelf-life to 12–16 days, offering promising applications in packaging materials. However, further advancements are required to address the limitations and enable large-scale trials during the mass production stage. Expecting to achieve optimized process formulations and conditions for CT or other agricultural product packaging materials.

This study investigated the practical feasibility of synergistically and optimally applying ultrasound-assisted osmotic dehydration (UAOD) practices for the pineapple slice picking process (in sugar osmotic solution), with potential implications for improving current practices. This study was carried out to evaluate the effects of different treatment conditions of single (40 and 80 kHz)/multiple (40/80 kHz) frequencies, output powers (300, 450, and 600 W), and treatment time (5–40 min) at 30, 45, and 60 °Brix applied, respectively, on the pineapple slices picking process. The sound pressure of the UA was also measured to confirm that it provided the corresponding effect stably under different conditions. The ideal UAOD operating condition for pineapple slices is a 45 °Brix sugar osmotic solution, with frequency multiplexing at 40/80 kHz and an output power of 450 W for 25 min, which yields the optimal solids gain (SG) rate of 7.58%. The above results of this study indicated that UAOD could improve the accelerated quality transfer of pineapple slices and enhance the final product quality, thereby increasing the efficiency of the dehydration process and saving processing costs and time.
