Influence of inorganic content on hydrochar quality from high-ash agar extraction waste via hydrothermal carbonization

Agar solid waste (ASW) has potential as a feedstock for hydrochar production because of its organic content; however, its high inorganic fraction, predominantly silica, limits its application. Furthermore, studies specifically investigating the hydrothermal carbonization (HTC) of ASW remain limited, given its high ash...

Effect of Fermentation Time and Spray Drying Inlet Temperature on the Quality of Egg White Powder

Eggs are an affordable and widely consumed protein source but have a limited shelf life due to their perishable nature. Converting egg white into powder through fermentation and spray drying offers a promising preservation method; however, the combined effects of these processes remain insufficiently studied. This rese...
