Determination of the chemical and mineral composition of citrus by-products in relation to its utilization as a feed raw material
Hristina Neshovska
Abstract: The global food industry and especially fruit juice production generates millions of tons of organic waste annually. Citrus waste, also known as citrus pulp оr citrus pomace, is a residue obtained during various citrus juices production. This by-product has the potential to become an excellent source of essential nutrients in animal feeding. In the current study, the chemical and mineral composition were
determined in the citrus waste by Orange (Citrus sinensis), Lemon (Citrus limon), Red grapefruit (Citrus paradisi), Mandarin (Citrus reticulata), Lime (Citrus aurantifolia), Pomelo (Citrus maxima). Waste products are derived from the production factory of freshly squeezed fruit and vegetable juices located in the village of Musachevo, Western Bulgaria. For all citrus waste, the following indicators were determined: dry matter (DM), moisture (RH), crude protein (CP), crude fibre (CF), crude ash (CA), ether extract (EE), manganese (Mn), zinc (Zn), magnesium (Mg), calcium (Ca), phosphorus
(P), sodium (Na), potassium (K). The mineral content was determined by Atomic Absorption Spectrophotometer. Their chemical and mineral composition analyses showed differences in the distribution of nutrients and minerals. The data obtained from the conducted analyses showed that citrus pulp could successfully replace some of the main raw materials in the animal’s ration, as it is a source of essential nutrients for it.
