柠檬酸工业英文文献和中文翻译(9)
The commercial development of such a process would revolutionize present methods of manufacture. Producers of the naturally occurring citric acid may, therefore, in the future be subjected to competition more severe than that which now exists. Satural citric acid pro- duction in the United States is definitely limited to the amount of cull citrus fruit available and probably seldom exceeds 3,500,000 pounds annually. It is not known whether the manufacture of citric acid from cull citrus fruits and other wastes could be operated profitably if prices were further re- duced. Improved methods of manufacture to reduce operat- ing costs may be necessary to compete successfully with the fermentation citric acid industry.
