Interaction mechanism of carotenoids and polyphenols in mango peels
Food Research International, 2023In this study, carotenoids and polyphenols were demonstrated to be the major active substances in the crude pigment extracts (CPE) of mango peels, accounting for 0.26 mg/g and 0.15 mg/g, respectively. The interactions between carotenoids and polyphenols in CPE was observed, as evidenced by that polyphenols significantly improved the antioxidant ...

Peel Mechanics for an Elastic-Plastic Adherend
Rubber Chemistry and Technology, 1977Abstract The force required to propagate a 180° bend in an elastic-plastic strip has been calculated from elementary bending theory. Measured forces for Mylar strips of various thicknesses, bent to various degrees, were in good agreement with these calculated values.

Peel mechanics of adhesive joints
Polymer Engineering & Science, 1977AbstractA review is given of the mechanics of peeling rupture of an adhesive joint, consisting of a flexible adhering strip peled away from a layer of adhesive. Attention is drawn to a number of anomalous results that cannot be accounted for solely, in terms of the thermodynamic work of formation of two new surfaces.

Mechanism study on the sugarcane seed peeling method
Proceedings of the International Symposium on Big Data and Artificial Intelligence, 2018In this paper, the mechanism study of sugarcane leaf stripping method was proposed, and the stress analysis of sugarcane leaf stripping process was conducted. First peel leaf component alignment and experimental study on the screw is arranged in two ways, respectively, examines the ways for stripping leaves, along with the change of sugar cane blow ...

Peeling mechanism of tomato under infrared heating: Peel loosening and cracking
Journal of Food Engineering, 2014Critical behaviors of peeling tomatoes using infrared radiation heating are thermally induced peel loosening and subsequent cracking. Fundamental understanding of the two critical behaviors, peel loosening and cracking, remains unclear. This study aimed at investigating the mechanisms of peel separation for tomatoes subjected to a newly developed ...

Mechanical Peeling of Anthracene Dimers
Angewandte ChemieABSTRACT In polymer mechanochemistry, mechanophores are activated by the pulling action of polymer arms. This activation can be achieved from various pulling geometries, the most common being shearing, where tensile stress is distributed across the entire structure, and peeling, which concentrates tension on one ...

Mechanics of peeling of rubbery materials. I. Peel strength and energy dissipation
Journal of Polymer Science: Polymer Physics Edition, 1975AbstractThe peel strength found in the trousers‐type peeling process is treated for the case in which the adherends, assumed to be flexible but inextensible are bonded by rubbery viscoelastic adhesives.Taking into consideration energy dissipation during deformation of the adhesive, Griffith's criterion is extended to the peeling of viscoelastic ...

Peel mechanics with large bending
International Journal of Fracture, 1977Previous small bending models for the peeling of an elastic strip from a rigid substrate are extended to large bending. Computational results obtained by an initial value method are presented. One finding is that the present large bending analysis and the conventional models based on energy considerations predict the same dependence of peel force on ...

Storage of mechanically peeled oranges and grapefruit
Postharvest Biology and Technology, 1994Abstract Oranges and grapefruit stored intact or mechanically peeled (albedo removed and cored) for up to 5 weeks at 0°C were evaluated regularly to determine if sensory differences were detectable. Additionally, affective testing was completed to assess the effect on hedonic response.

Mechanics of peeling of rubbery materials. II. Initiation and propagation of peeling
Journal of Polymer Science: Polymer Physics Edition, 1978AbstractThe peel strength of a joint with flexible materials bonded by an elastic adhesive was evaluated in relation to the fracture mechanism. It was found that initiation and propagation of peeling are governed by different mechanisms. Initiation (the formation of an initial crack) occurs when the maximum stress in the adhesive layer reaches a ...
