Short-term stressors such as transport and slaughter include psychological and physical stimuli that might be aversive for the animals.Restraint, manipulation and sudden change lead to fear, or psychological stress, while hunger, thirst, fatigue, injury and extreme thermal conditions are considered as physical stresses.Animal responses to these sti
NONENZYMATIC BROWNING KINETIC REACTION AND ASCORBIC ACID DEGREDATION OF HEAT-TREATED ORANGE JUICE DURING STORAGE
The kinetics of ascorbic acid (AA) False nails degradation and nonenzymatic browning (NEB) of heat-treated single strength orange juice (OJ) over a temperature between 70-95 oC for 2-10 min.and stored under opaque condition at 4 and 20 oC for 2 months have been studied.Analysis of kinetic data by measuring absorbance at 420 nm (A420) suggested a ze
Aerobic fermentation prior to pasteurization produces a selective substrate for cultivation of the mushroom Pleurotus pulmonarius
Description of the subject.Pleurotus species are cultivated on lignocellulosic substrates, in which contaminant fungi such as Trichoderma spp.are common.A selective substrate for Pleurotus provides the necessary conditions for protection against contaminants.Studies show that Paenibacillus polymyxa and other thermophilic bacteria benefit from the s
