The study investigated the extraction of astaxanthin-rich oil from shrimp waste biomass, a valuable byproduct rich in functional lipids and proteins. Wet rendering has long been an inexpensive method to extract oil, however the high temperatures and long cooking times negatively affect the amount of astaxanthin. On the other hand, the study looked into employing deep eutectic solvent as a green solvent and combining a wet rendering process with high-shear homogenization and high-frequency ultrasound-assisted extractions. DES-UAE at 60% amplitude and wet rendering at 60 °C were found to be the ideal conditions, as were DES-HAE at 13,000 rpm and wet rendering at 60 °C. With a notable increase in oil yields of 16.80% and 20.12%, respectively, and improved oil quality (lower acid and peroxide values) in comparison to the conventional wet rendering, experimental validation validated the effectiveness of the DES-HAE and DES-UAE procedures. DES-UAE notably raised the amount of astaxanthin. This study demonstrates that DES-HAE and DES-UAE are quicker, lower-temperature substitutes for obtaining premium, astaxanthin-rich shrimp oil, resulting in more effective use of this priceless byproduct.

In the development of high protein jasmine rice products, hydrocolloids, HPMC at 0, 0.25, 0.5 and 1% w/v and MD at 10% w/v were used. This hydrocolloid contained 30% w/v dissolved protein and was coated with raw jasmine rice. It was found that different amounts of HPMC affected the adhesion of proteins in rice. Then, the hydrocolloid with the best adhesion, 0.25% w/v, was used to find the optimum amount for coating rice at ratios of 1:3 and 1:5, which affected protein content, texture, color, water retention and sensory acceptability.

This conceptual model, inspired by the Rose Window in Gothic architecture, embodies intricate geometric patterns that reflect divine harmony and balance. Its symmetrical structure and the interplay of light passing through stained glass create a sense of movement, enhancing the sacred and mystical atmosphere. The composition evokes a celestial presence, like a window to heaven.
