Abstract:
This paper has studied the technological process and reaction conditions of the preparation of sodium copper chlorophyllin from bamboo and poplar leaves. The resu(?), show the best reaction conditions as follows: extraction by mixture of ethanol and acetone, soaption for 50min by 5% NaOH, reaction with 20% CuSO4 for 30min at 80℃ , preparation of sodium copper chlorophyllin by NaOH. The quality of our product accords with the specification of National Standard for food additives GB3262-82. Yields 0.25%-0.3% (fresh bamboo leaves)
