Purpose of this study was to develop prototype cooking equipment that can work at reduced pressure and to evaluate its performance for production of strawberry jam. The effect of vacuum cooking conditions on color soluble solid content, reducing sugars total sugars HMF and sensory properties were investigated. Also, the optimum vacuum cooking conditions for strawberry jam were optimized for Composite Rotatable Design. The optimum cooking temperature and time were determined targeting maximum soluble solid content and sensory attributes (consistency) and minimum Hue value and HMF content. The optimum vacuum cooking conditions determined were 74.4 °C temperature and 19.8 time. The soluble solid content strawberry jam made by vacuum process were similar to those prepared by traditional method. HMF contents of jams produced with vacuum cooking method were well within limit of standards.

Sous vide, a cooking method that involves vacuum-sealed fish at low temperatures, yields a uniquely tender, easily flaked texture. Previous research on sous-vide tenderization has focused on thermal protein denaturation. On the other hand, the contribution of proteases, activated at low temperatures in fish meat, has been suggested.

Ready-to-eat (RTE) abalones, scallops and oysters were prepared through a process of cooking, drying, vacuum packaging, and high-temperature sterilization, and were subjected to accelerated storage. Upon storage, the three RTE shellfishes all showed color deterioration, as indicated by darker color, decreased L* and W* values, and increased a* value. In contrast, the color deterioration of RTE oysters was more pronounced.

The impact of cultivar and production system was studied over two years on organoleptic and nutritional characteristics of apple fruits and then, on purees processed with both conventional convection cooking under vacuum and fast innovative microwave cooking. The main factors affecting the content and composition of sugars, organic acids, volatiles, polyphenols, and fibre were in the decreasing order, cultivar, year, and production system. Regarding processing, the fast innovative microwave cooking led to puree with a higher viscosity but with a lower polyphenol content compared to the convection cooking.

With the rising trend of consumers opting for healthier food items with low oil content, it is imperative to reduce the oil uptake of fried products. The inefficiencies of traditional technologies, including a low heat utilization rate and poor processing efficiency, have been increasingly exposed in industrial production of fried products. This review offers an extensive analysis of the effects of innovative pretreatment techniques (pulsed electric field, ultrasound, high-pressure processing, microwave, radiofrequency, and combined processes) and various novel frying processes (vacuum frying, high pressure frying, microwave frying, infrared frying, ultrasonic-assisted frying and their combinations) on the microstructure modifications and oil uptake of fried foods.
