Study of Methanol Formation During Soda-AQ Cooking Process of Silver Grass
摘要
Abstract
Methanol formation during soda-AQ cooking process of Silver grass was investigated by using the headspace chromatography(HSGC). The formation regulations of methanol in different cooking conditions with different alkali charge, cooking temperature and holding time were also studied. The results showed that alkali charge,holding time and cooking temperature all had great influence on the methanol formation. With the increase of the alkali charge, holding time and cooking temperature, the amount of the methanol formation increased rapidly. When the alkali charge increased from 10% to 20%, the generated methanol changed from 2.34 kg/t(odp)to 5.06 kg/t(odp). When the holding time extended from 10 min to 40 min.the generated methanol changed from 2.08 kg/t(odp)to 3.88 kg/t(odp). When the cooking temperature increased from 145 ℃ to 170 ℃, the amount of the methanol varied from 2.02 kg/t (odp) to 4.37 kg/t(odp). But the heating up time has a relatively small effect on the amount of methanol formation.关键词
