oach, technique and implants have to be collectively used to reach a strategy that mitigates and ideally prevents dislocation.The effect of hydrolysis degree of gallotannins (GT, 1 mg/g) on cross-linking of nano-size collagen catalyzed by laccase (12 U/g) was studied, and the antibacterial properties of GT hydrolysates (HGT)-laccase (Lac) collagen films on minced cod were also investigated. The results showed that the tensile strength of HGT-Lac films (87.23-100.77 MPa) was higher than those added HGT alone (85.59-95.58 MPa) under the same hydrolysis degree of GT. Compared to the denaturation temperature (78.05 °C) of pure nano-size collagen film without addition of HGT and laccase, the denaturation temperature of HGT (80.75-86.30 °C) and HGT-Lac (91.97-101.64 °C) films increased greatly, especially for HGT-Lac films. Moreover, both HGT and HGT-Lac films showed some mild antibacterial properties for minced cod during storage at 4 °C for 8 days. Therefore, the combination of HGT and laccase could improve the performance of nano-size collagen film and extend the application of collagen in biodegradable/edible packaging.To investigate the effect of relative humidity (RH) on chilling injury (CI), zucchini fruit were stored in cold rooms (4 ± 0.4 ℃) with different RHs (near-saturated RH [NSH] with 96-100% and normal RH with 72-76% served as control). Storage in NSH delayed weight loss and CI, maintained firmness and skin color. Higher antioxidant enzyme activities and greater scavenging capacities of free radicals were found in NSH-fruit than in the control fruit. The decrease of the unsaturated fatty acids was delayed in NSH-fruit due to lower activities of related membrane lipid degrading enzymes as compared to the control fruit. NSH-fruit also maintained higher activities of energy metabolism-associated enzymes than control fruit, leading to high levels of adenosine triphosphate (ATP). Taken together, we attributed the alleviation of CI by NSH storage to its enhancement of antioxidant capacities and its effect on maintaining higher energy status in zucchini fruit.The valorization of the brewer's spent grain (BSG) generated in a craft beer industry was studied by subcritical water hydrolysis in a semi-continuous fixed-bed reactor. Temperature was varied from 125 to 185 °C at a constant flow rate of 4 mL/min. Biomass hydrolysis yielded a maximum of 78% of solubilized protein at 185 °C. Free amino acids presented a maximum level at 160 °C with a value of 55 mg free amino acids/gprotein-BSG. Polar amino acid presented a maximum at lower temperatures than non-polar amino acids. The maximum in total phenolic compounds was reached at 185 °C. This maximum is the same for aldehyde phenolic compounds such as vanillin, syringic and protocatechuic aldehyde; however, for hydroxycinnamic acids, such as ferulic acid and p-coumaric, the maximum was obtained at 160 °C. This allows a fractionation of the bioactive compounds. Subcritical water addresses opportunities for small breweries to be incorporated within the biorefinery concept.Heat processing of ready-to-drink beverages is required to ensure a microbiologically safe product, however, this can result in the loss of bioactive compounds responsible for functionality. The objective of this study was to establish the thermal stability of a novel dihydrochalcone, 3',5'-di-β-d-glucopyranosyl-3-hydroxyphloretin (2), 3',5'-di-β-d-glucopyranosylphloretin (3) and other Cyclopia subternata phenolic compounds, in model solutions with or without citric acid and ascorbic acid. The solutions were heated at 93, 121 and 135 °C, relevant to pasteurisation, commercial sterilisation and ultra-high temperature (UHT) pasteurisation, respectively. For most compounds, the acids decreased the second order reaction rate constants, up to 27 times. Compound 2 (46.29 ± 0.53 (g/100 g)-1 h-1), and to a lesser extent compound 3 (5.94 ± 0.01 (g/100 g)-1 h-1) were the most thermo-unstable compounds when treated at 135 °C
