Citrus juice centrifugation pulp is the semi-solid product obtained from the industrial centrifugation of juices, to obtain a clear juice. This waste causes many economic and environmental problems because of its fermentability. In this paper we describe a method which makes it possible to obtain animal feed from citrus juice centrifugation pulp. To this end, alkaline and/or enzymatic treatments were carried out on the centrifugation pulp. These treatments facilitate pressing and so help to produce a material which, using suitable methods, may be dried. Enzyme treatment proved to be the most efficient of the methods under investigation designed to favour the pressing of the pulp. The product obtained with this method showed excellent digestibility in vitro and its protein content, although not especially high, compared favourably with that of many other agroindustrial waste products currently used as components of animal feed.

Abstract

Citrus juice centrifugation pulp is the semi-solid product obtained from the industrial centrifugation of juices, to obtain a clear juice. This waste causes many economic and environmental problems because of its fermentability. In this paper we describe a method which makes it possible to obtain animal feed from citrus juice centrifugation pulp. To this end, alkaline and/or enzymatic treatments were carried out on the centrifugation pulp. These treatments facilitate pressing and so help to produce a material which, using suitable methods, may be dried. Enzyme treatment proved to be the most efficient of the methods under investigation designed to favour the pressing of the pulp. The product obtained with this method showed excellent digestibility in vitro and its protein content, although not especially high, compared favourably with that of many other agroindustrial waste products currently used as components of animal feed.
