Tailoring the surface properties and flexibility of starch-based films using oil and waxes recovered from potato chips byproducts.

Agrofood byproducts may be exploited as a source of biomolecules suitable for developing bioplastic materials. In this work, the feasibility of using starch, oil, and waxes recovered from potato chips byproducts for films production was studied. The recovered potato starch-rich fraction (RPS) contained an amylopectin/amylose ratio of 2.

Recent Advances in the Production and Applications of Ellagic Acid and Its Derivatives. A Review.

Ellagitannins (ETs), characterized by their diversity and chemical complexity, belong to the class of hydrolysable tannins that, via hydrolysis under acidic or alkaline conditions, can yield ellagic acid (EA). They are mostly found as a part of extractives in angiosperms. As known antioxidants and chelators, EA and EA derivatives are drawing an increasing interest towards extensive technical and biomedical applications.

Characterization data of pulp fibres performance in tissue papers applications.

The data presented in this article are related to the original research paper entitled "Comparative characterization of eucalyptus fibres and softwood fibres for tissue papers applications" available in Materials Letter: X Journal [1]. In this article, six eucalyptus hardwood pulps and six softwood pulps were characterized in terms of morphological, chemical and water-related (by drainability and water retention index) properties. In addition, using these pulps, unpressed laboratory isotropic handsheets were produced with a basis weight of approximately 20 g/m, similarly to tissue papers.

Oxidation of amylose and amylopectin by hydroxyl radicals assessed by electrospray ionisation mass spectrometry.

The hydroxyl radicals (HO) are one of the most reactive oxygen species (ROS) involved in the oxidative damage of biological molecules, including carbohydrates. During the industrial processing of food, ROS can be formed. In order to identify the structural changes induced in starch by oxidation, amylose, amylopectin, and maltotriose, an oligosaccharide structurally related to these polysaccharides, were subjected to oxidation with HO generated under Fenton reaction conditions (Fe(2+)/H2O2).
