Difficult to dissolve in water, soluble in dilute hydrochloric acid and nitric acid, in the air and stability.
难溶于水,易溶于稀盐酸和硝酸,在空气中稳定。
Under the proper temperature, the proper dilute hydrochloric acid liquid can reach 20% or so of pectin production rate.
适当浓度的盐酸在适当的温度、时间下可以得到20%左右的果胶产率。
The influence of experimental conditions, which were taking the pectin out by means of soaking the sugar-beet bagasse with dilute hydrochloric acid liquid was studied.
本文讨论了利用稀盐酸从甜菜渣中浸提果胶的实验条件对产率的影响。
The residue was washed with dilute hydrochloric acid solution, The precipitation was dried, purified, and identified by the infrared spectrometry (IR) and high mass spectrometry(HRMS)with DES-HS.
