Special Issue Information

Dear Colleagues,

Along with environmental conditions such as climate change, water scarcity and food processing waste are important for the food industry, and consumers' food preferences are changing daily. The food industry is developing dynamically to reduce environmental impacts and meet consumer needs as much as possible.

This Special Issue on Recent Advances and Trends in Food Processing aims to present current, original scientific articles and review articles on recent developments in the food process with new food products.

One of the primary factors for the mentioned Special Issue is novel green techniques, including high-power ultrasound, high hydrostatic pressure, ionizing and ultraviolet radiation, ohmic heating, and pressurized carbon dioxide. Zero waste is another important factor for the food industry's sustainability. The processes of alternative proteins, like edible insects, provide new ways to tackle hunger and are issues that the food industry should take into consideration nowadays, as well as alternatives in consumer preferences. The process of 3D printed foods is another novel food production process that serves consumer preferences. Non-thermal food processing methods can ensure that we obtain products with high nutritional value and are alternative processes that prevent the formation of non-healthy components.

Drying extends the shelf life of crops; thus, dryers with good designs will help them dry to an optimum level. The present research work was carried out to assess and compare the performance of conventional (CD), solar tunnel (STD), and solar-cum gas-fired dryers (SGD) for drying hot chilies. The Sanam variety of hot chilies was used in this study. Samples were dried using CD, STD, and SGD methods. The drying process was conducted over three days, from 9:00 to 17:00 daily. Results showed significant differences among the drying methods in temperature, relative humidity, and moisture content reduction (p < 0.0001). The SGD consistently outperformed the other methods, achieving the highest temperature (55 °C) and lowest relative humidity (17%), compared to the STD (44 °C, 23%) and CD (34 °C, 31%). The SGD demonstrated superior efficiency, reducing moisture content from 70% to 9.36% in just 36 h, while the STD required 50 h (to 11.37%) and CD took 84 h (to 9.63%). ANOVA and post hoc analyses revealed that the SGD significantly outperformed both the STD (p = 0.0412) and CD (p = 0.0018) in moisture content reduction. Additionally, the SGD and STD better preserved the color of hot chili samples compared to CD, as determined by the Essential Oil Association (EOA) method. It is concluded that the SGD is the most technically suitable method for drying hot chilies, offering improved efficiency and quality retention. It is recommended to use an SGD for optimal results in hot pepper drying. Full article
