Multifractal Approaches of the Ring Tensile Rupture Patterns of Dried Laver (Porphyra) as Affected by the Relative Humidity

Abstract

Texture properties are the most important quality attributes for commercial dried laver (DL) products. The relative humidity influences the texture properties of DL during production, storage, shipping, and consuming. This study well characterized the effect of the relative humidity on the texture properties of DL using the tensile tests under microclimate conditions. This information is very practical and can be immediately applied to control the relative humidity of the packaging and the storage room for DL.

Image-based analysis of uniaxial ring test for mechanical characterization of soft materials and biological tissues

“…The simplicity of the method makes it attractive for the characterization of a wide range of materials, ranging from ring-shaped hydrogels 1 to food products. 2 Indeed, the uniaxial ring test is the official standard for tensile testing of elastomers (ASTM D 1414), 3 established for use by the O-ring industry. 4 More recently, uniaxial ring test has also found a large application area in the mechanical characterization of biological tissues and biomaterials.…”
