WebJan 27, 2024 · Structurally, the amylose provides crystallinity and entanglement of starch, leading to improved strength. However, the amylopectin short and branched chains give a brittle disadvantage to the starch elasticity. So, in order to perfect the performance of a film, hydrolysis is required to produce the more enhanced quality of the starch. WebThen, the production of starch bioplastic using solution casting was carried out with the addition of CNC. The results showed chemical treatments affected the functional group, increasing the crystallinity index, and removing the fibril structure in water hyacinth fibers. Likewise, the addition of CNC to starch bioplastic fluctuated the tensile ...
WebThe bioeconomy aims to discover new sources for producing energy and materials and to valorize byproducts that otherwise would get wasted. In this work, we investigate the possibility of producing novel bioplastics, made up of argan seed proteins (APs), extracted from argan oilcake, and amylose (AM), obtained from barley plants through an RNA …
