In this study, 7-O-kojic acid monopalmitate (7-O-KAP) was synthesized using palmitic acid and kojic acid where the yield and biological activities were analyzed. The highest yield of 7-O-KAP (43%) can be obtained at molar ratio of 1:1, enzyme loading of 5% (w/v), temperature of 70 ◦C, using immobilized lipase N435 in solvent-free system. Stirred tank reactor (STR) provides better mixing of the ...

The fabrication of high-quality low-fat 3D printed foods is strongly dependent on the development shear-thinning, viscoelastic, and thixotropic ink with a monomodal particle size distribution. In this study, oil was partially or totally replaced hydrophobically modified biosurfactants (acetylated starch, octenyl succinic anhydride ethyl (hydroxyethyl) cellulose, dodecenyl succinylated inulin) i...

The application of surface-active biopolymers supports opportunities and novel prospects to generate a well-defined printable ink for 3D printing. In this regard, an ideal must show pseudoplastic, viscoelastic, thixotropic characters with recoverable structure so as be effectively printed desired printability. Here, microcrystalline cellulose was hydrophobically modified through facile sustaina...

This study provides an overview of the rheological properties aqueous polyurethanes (WPU), as main component, or a thickening additive in formulations. Waterborne (WPU) have been proposed environmentally friendly alternative to conventional solvent-based solutions variety industrial applications such coatings, adhesives, inks. In all these fields, control became important prerogative determine ...

Celiac disease is a serious and lifelong disorder that associated with gluten consumption. patients should commit to strict free diet. Besides celiac patients, can also cause allergenic reactions in significant portion of population. Thus, there growing trend replacing sources alternatives. This work concentrated on improving the quality consumer acceptance gluten-free cakes made out rice flour...

Abstract. Jayus J, Akroman R, Nurhayati, Nugraha AS, Piluharto B, Seviour RJ. 2021. Structural elucidation of the exopolysaccharide produced by Curvularia lunata isolate RJ01. Biodiversitas 22: 2699-2705. An (EPS) was recovered from culture filtrates fungus RJ01 prepared in Jember, Indonesia. Based on a prominent peak at 883 cm-1, FTIR analysis suggested it is ?-D-glucan, proposal confirmed sub...

The effect of polycarboxylate superplasticizer on the fluidity and rheology cement - silica fume water paste was investigated. changes dispersion degree, yield stress plastic viscosity with different content were analyzed. results show that rheological properties conform to Herschel-Bulkley model. shear thinning slurry is manifested as a typical yielding pseudoplastic fluid characteristic. When...
