Abstract

The structural heterogeneity and complexity of plant cell wall polysaccharides limit the release of phytonutrients in food processing, ultimately affecting the sensory quality, nutritional value, and shelf stability of products. Efficient enzymatic hydrolysis using plant cell wall polysaccharide-degrading enzymes (PCWPE) is a key step in overcoming the plant cell wall, a chemically complex structure composed mostly of polysaccharides, in food processing. PCWPE include cellulase, hemi-cellulase and pectinase, which specifically and efficiently hydrolyze glycosidic bonds in plant cell wall polysaccharides, significantly improving the sensory flavor and nutritional value of products, enhancing the stability of multiphase systems, and increasing the product yield. In recent years, PCWPE have been widely used in beverage processing, phytonutrient extraction, functional sugar preparation, and the processing of emerging sustainable plant-based food and thereby have become a research hotspot in the field of green food processing. This article summarizes the latest research on the mechanism of action of PCWPE, efficient enzymatic hydrolysis techniques and their application in the food industry, with a view to providing a reference for technological innovation in the field of high-quality plant-based food processing.

Abstract

In order to provide genetic parameters of growth and Quambalaria shoot blight (QSB) resistance in Corymbia citriodora subsp. variegata (CCV), two trials of 91 open-pollinated families from 10 provenances were established in southern China. Effects of variance components of provenance and/or family within provenance were significant (p ≤ 0.05, 0.01, or 0.001) for most growth traits (tree height at seven, 12, 21, 29, and 46 months as well as breast-high diameter and single-tree volume at 21, 29, and 46 months) and QSB resistance (at 7 months) at each trial and across trials. Narrow-sense heritability estimates ranged from 0.04 to 0.46 in growth and 0.01 to 0.27 in QSB resistance, indicating generally low to moderate levels of additive genetic control of the traits studied. Proportions of provenance to phenotypic variance were also generally low, being 0.02–0.22 for growth and 0.01–0.23 for QSB resistance. Genetic correlations were significant and positive between growth traits and also between growth and QSB resistance, meaning that better growth at older ages could be expected from early-stage selection in growth and/or QSB resistance in CCV. Except for 29-month-old breast-high diameter, type-B correlations between trials were significant for all the traits, which suggested strong genotype by environment effects.

32. Influence of temperature rate on transitory internal friction during reverse martensitic transformation for Ti50Ni27Cu23 alloy.

Abstract

Internal friction (IF) spectra during reverse martensitic transformation from 35 to 135°C at different temperature rates of 0.5, 0.75, and 1°C/min for Ti50Ni27Cu23 shape memory alloy (SMA) samples were measured with a dynamic mechanical analyzer, respectively. The IF spectra were characterized by IF peak increasing progressively and peak shifting toward high temperature with an increase in temperature rate. An iterative approach was used to calculate the precise intrinsic and approximate transitory IF contributions to the normal IF spectrum. The quantitatively analyzed results indicate that the transitory IF of this alloy is nonlinearly dependent on the temperature rate and obeys a power law with a power coefficient of 0.55. The predicted and experimental IF spectra at different temperature rates of 0.75 and 1°C/min agree well with each other, respectively. [ABSTRACT FROM AUTHOR]
