Storage ripening

It is remarkable that neither of these workers appears to have investigated aqueous preparative methods, despite the fact that Cross and Bevan and their colleagues, from 1892 onward, had been developing the Viscose process for cellulose, and had, in 1907, applied similar reaction-conditions to starch. The formation of a starch viscose imder aqueous conditions was confirmed later by Ost and coworkers, who found that the solution decreased in viscosity on storage ( ripened ), like cellulose Viscose, but with no accompanying separation of starch. Various industrial uses for starch xanthate have since been suggested for example, as a frothing... 

One of the major factors contributing to reported variations in xanthation is probably the stability of xanthate groups [170-172]. The primary xanthate at C6 was generally shown to be more stable than those at C2 and C3 positions and the latter groups could be hydrolyzed 15-20 times faster under certain conditions. Thus the extent of hydrolysis and the redistribution of xanthate groups varied with the duration of xanthate solution (viscose) in storage (ripening).

Despite the potent influence of ethylene on the whole plant development, most often it has been recognized as a fruit-ripening and senescence-associated hormone. With respect to the gaseous nature of this hormone, the knowledge about ethylene sensitivity of fruit and flower is necessary to predict the effects of their mixed storage and transport and the usefulness of anti-ethylene treatments. Such commercial implications of ethylene have made it a topic of investigation for decades.
