Maltodextrin As Fat Replacer in Food Products: A Review
Partial hydrolysis of starch yields a product called maltodextrin, which has a dextrose equivalent of less than 20. Maltodextrin with a dextrose equivalent of less than 10 is used as a fat replacer in various products. Industries are constantly developing low-fat products or reducing the fat content of products as much as possible according to the wishes and tastes of consumers so that the calo...
متن کاملCuring and thermal behavior of epoxy resins of hexafluoro - bisphenol – A and bisphenol - A
This paper describes the synthesis and characterization of epoxy resins based on (hexafluoroisopropylidene)diphenol (EFN) and p,p’-isopropylidenebisphenol (EBN), respectively and 4, 4’(hexafluoroisopropylidene)dipthalic-imideamine (IMAM), a curing agent. The synthesized epoxy resins and IMAM curing agent were characterized by Fourier Transform Infrared (FTIR) and 1H Nuclear Magnetic Resonance (...
متن کاملA Comparative Study of Bisphenol-A, Hydantoin and Cyanuric Acid Based Epoxy Resins Using XRD
To evaluate the efficiency of modified epoxy resins using bisphenol-A, hydantoin & cyanuric acid & to investigate the structural change due to the presence of Nitrogen atoms in polymeric chain for improved insulating properties, weatherability etc. The samples of epoxy resin bisphenol-A, hydantoin and Cyanuric acid based was taken for X-ray diffraction analysis. The diffraction patterns were Fo...
