影响大豆分离蛋白乳化稳定性测定的几种因素研究 总被引:2,自引:0,他引:2
采用离心法对影响大豆分离蛋白乳化稳定性的测定结果的几种因素进行了研究。通过研究得出如下结论:对乳化稳定性影响最大的是油相体积分数,然后依次是蛋白质溶液浓度、pH、离子强度、离心速度。在测定的范围内,均质速度、均质时间、水浴加热时间、加热温度和离心时间对测定结果的影响都很小。 相似文献

The α-acids content of baled hops (Pride of Ringwood) stored at ?20°C, ?5°C, +5°C and +22°C was monitored over a twelve month storage period. The α-acids content of the hops was found to decrease at a linear rate, i.e., by zero order kinetics, at each storage temperature. The relationship between reaction rate and storage temperature was found to accord with the predictions of classical reaction kinetics, enabling a prediction of the stability of hops stored at various temperatures to be made. 相似文献

Barley samples, which varied in maturity, were either steeped with calcium hypochlorite and then with a mixture of antibiotics, or in water, for twenty or sixty hours. The steeped grains were placed on agar and were scored for germination, growth of rootlets and α-amylase production at intervals up to ninety six hours after draining. The rates and final percentages of germination, rootlet growth per germinated corn and α-amylase per germinated corn were all greater where grain had been steeped with antimicrobial agents compared to water-steeped control samples of grain. It was confirmed that the antimicrobial agents reduced the extent of inhibition of germination which followed extended steeping. Thus controlling microbes increased grain germinability and the vigour of the grains which germinated. However, the vigour of more water sensitive grain was not increased enough to be equal to that of mature grain by reducing microbial activity . Experiments in which grain was reinfected with a suspension of microbes, following steeping with antibiotics, supported the theory that the observed effects were due to reductions in microbial activity and not any secondary effects of the antimicrobial agents. 相似文献

Detailed microscopic study of the covering layers of the mature barley grain shows that beneath the husk the pericarp consists of highly compressed cell material bound by a thin outer cuticle. The testa is a double cell layer, also bound by an outer cuticle. An innermost cuticular membrane separates the testa from the remains of the nucellus. This membrane is of nucellar origin and not part of the testa. The outer cuticle of the testa is incomplete in the ventral furrow and in the micropylar area of the grain. The absence of the testa cuticle and the relatively uncompressed nature of the pericarp at the micropyle may facilitate uptake of solutes by the embyro. 相似文献
