The decisive influencing factor of viscosity in carboxyl-methylation was cross-linking reaction. Carboxyl-methylation was the main influencing factor of solubility and swelling capacity in modification of high content amylose starch. The structure and gelatinization property of different amylose content were analyzed with an Olympus Vanox BHS-2 multi-function optic microscope, and the results were as follows. The structure of ordinary cornstarch was different from the high amylose; gelatinization temperature and pH value of starch were affected deeply by amylose content, but had little difference between the gelatinization of high content amylose starch contained 50% and 70% amylose; pH value had much more effect than temperature on the gelatinization of high content amylose cross-linked starch. Monochloroacetic acid consumption, alcohol concentration and pH value influenced the starch carboxyl-methylation. When alcohol concentration was 60%, pH value 10, monochloroacetic acid/starch mass ratio 55%, the carboxyl-methylation of high amylose cross-linked cornstarch had the best result. With the In-Vitro digestibility model and biodegradation experiment, the digestibility and biodegradability of high amylose cornstarch and its modified starch were detected.

The innovation of this article is the perspective of "columnized survival". On the one hand, it carries out the summary the course of development of more than 10 years of columnized documentary, positively affirmed the trend of plebification with on-the-spot report concept and the trend of story expressed with entertainment concept; on the other hand, the article carries out meticulous analysis on the existing character of columnized documentary and the differences of non-columnized documentary of tradition. After having analyzed a mass media objectively getting involved in documentary, the article carries out the change coming into being in aspects of documentary such as making idea, production process, aesthetic attributes, narrative technique and social function. It carries out the calm thinking on the appearing problem, and seeks new export to the documentary with columnized survival.
