  • Title: Effects of processing on protein nutritive quality of coconut Cocos nucifera products.
    Author: Mepba HD, Achinewhu SC.
    Journal: Plant Foods Hum Nutr; 2003; 58(1):15-25. PubMed ID: 12859010.
    Abstract:
    Pared, comminuted and blanched coconut meat was freeze-dried at 25 degrees C for 24 hours and pulverized. Whole coconut meal was solvent extracted with n-hexane to yield a defatted meal while full-fat coconut protein concentrate (FFC-PC) containing 27.60% protein was prepared by alkali extraction of undefatted meal followed by isoelectric precipitation. Defatted coconut meal had a significantly (p < or = 0.05) lower crude fat but higher protein content than whole coconut meal. Similarly, FFC-PC had a significantly (p < or = 0.05) higher protein but lower carbohydrate content than whole coconut meal and defatted coconut meal. Whole coconut meal, defatted coconut meal and FFC-PC had PERs of 1.98, 2.18 and 2.48 respectively, with NPRs of 2.86, 3.28 and 3.92, respectively. Protein digestibility values of 88.75%, 89.30% and 94.02% were obtained for whole coconut meal, defatted coconut meal and full-fat coconut protein concentrate, respectively. Growth response of animals showed that FPC-PC was superior to all other test diets.
