High hydrostatic pressure (HHP, treatment ≤700 MPa) is approved to be the most successful commercial nonthermal processing due its minimal modifications in nutritional and sensory quality. However, for some stable enzymes such as PPO, this unique technology can hardly inactivate them at below of 700 MPa. This study investigated effects ultrahigh (UHHP, >700 on activity Agaricus bisporus mushroom polyphenoloxidase (PPO) both phosphate buffer puree, structure enzyme by means circular dichroism...
Summary The inactivation of polyphenol oxidase (PPO) in peach juice and PPO carrot was investigated by high‐pressure carbon dioxide (HPCD), their kinetics analysed compared. temperature 35–55 °C, the pressure 5–15 MPa under HPCD condition. Results showed that enhanced effect on two PPOs. well fitted to a first‐order kinetic model, fraction‐conversion model as function temperatures or pressures. Susceptibility rate constant k not altered lessened temperature, but susceptibility changed when...
Abstract A cDNA library from a pool of all the seven silk glands tropical spider species was constructed. More than 1000 expressed sequence tag (EST) clones were created. Almost 65% EST identified and around 50% annotated. The cellular functional distribution indicated high protein synthesis activity in glands. Novel with repetitive amino acid sequences, which is one most important characteristics genes, isolated. One these clones, namely TuSp2 current research, contains two almost identical...
To facilitate development of new yak milk products with high added value, sterilization effects direct steam injection (DSI) were evaluated. The Z value (temperature increase necessary to reduce inactivation time by 90%) Geobacillus stearothermophilus spores (ATCC 7953; 106 CFU mL−1) in was 5.88 °C. Heating the above 153.86 °C for 0.116 s achieved complete ATCC 7953 spores; i.e., commercially-acceptable sterility. native lactoferrin and β-lactoglobulin (β-Lg) contents decreased 40 30% after...
The production of "Laba" garlic is limited to the homemade method with long processing time and non-uniform color quality. Innovative food technologies including high hydrostatic pressure (HHP) carbon dioxide (HPCD) were applied garlic. Products prepared at different treatment pressures (200, 350 500 MPa HHP; 4, 7 10 HPCD) compared by evaluating texture, color, flavor sensory qualities. results indicated that HHP 200 was optimal for retaining textural quality garlic, which mainly attributed...
ABSTRACT The inactivation of Staphylococcus aureus exposed to dense‐phase carbon dioxide (DPCD) was investigated, and the kinetics come‐up time (CUT) in pressurization monitored with come‐down (CDT) temperature fluctuation depressurization. CUT about 2.5, 3.5, 4.0 min; CDT 3.4, 3.7, 4.5 lowest samples depressurization 4, −1, −15 −22C, corresponding 10, 20, 30 40 MPa at 37C. behavior S. closely related variables process pressure, holding‐pressure (HPT), cycling. log reduction for 30‐min HPT...
Summary The inactivation of bacteria naturally present in strawberry pulp was investigated after high hydrostatic pressure ( HHP ) treatment at levels up to 600 MPa 25 °C for 5 ~ min. Five strains pressure‐resistant designated as A, B, C, D and E were isolated identified. five gram‐positive, spore‐forming, rods or rod chains. Growth the observed 30 45 °C, strain B also grew well 55 °C. They could produce acid from glucose catalase‐positive. Analysis 16S r RNA gene sequences showed that...
