<p>The objective of this study was to characterize morphologically the carob pods of both cultivated and wild Iferhounene varieties and to shed light on the techno-functional characteristics of carob bean gum extracted from the carob seeds of wild Iferhounene variety, namely: swelling index, water and oil holding capacities, emulsion stability and emulsifying power. Our findings revealed that carob pods of both cultivated and wild Iferhounene varieties had similarities with their European counterparts in terms of pod length, width, thickness, pod mass and number of seeds per pod. Nevertheless, the carob pods of our two varieties had differences with their European counterparts, in terms of pulp and seed masses and pulp and seeds rates. In addition, our data showed that galactomannans extracted from carob seeds of wild Iferhounene variety exhibited excellent swelling properties (145 ± 2 mL/g of dry CBG), a high water holding capacity (90 ± 1.3&#xa0;g of water/g of dry CBG), a low oil holding capacity (20 ± 0.12&#xa0;g of oil/ g of dry CBG), an interesting emulsifying power (67.9 ± 2.10%) and an optimum emulsion stability (50.66 ± 0.07%). Hence, the CBG extracted from carob seeds of the wild Iferhounene variety can be used efficiently in the food industry as a thickener and as a highly targeted drug-delivery system in the pharmaceutical industry as well.</p>

摘要

The objective of this study was to characterize morphologically the carob pods of both cultivated and wild Iferhounene varieties and to shed light on the techno-functional characteristics of carob bean gum extracted from the carob seeds of wild Iferhounene variety, namely: swelling index, water and oil holding capacities, emulsion stability and emulsifying power. Our findings revealed that carob pods of both cultivated and wild Iferhounene varieties had similarities with their European counterparts in terms of pod length, width, thickness, pod mass and number of seeds per pod. Nevertheless, the carob pods of our two varieties had differences with their European counterparts, in terms of pulp and seed masses and pulp and seeds rates. In addition, our data showed that galactomannans extracted from carob seeds of wild Iferhounene variety exhibited excellent swelling properties (145 ± 2 mL/g of dry CBG), a high water holding capacity (90 ± 1.3 g of water/g of dry CBG), a low oil holding capacity (20 ± 0.12 g of oil/ g of dry CBG), an interesting emulsifying power (67.9 ± 2.10%) and an optimum emulsion stability (50.66 ± 0.07%). Hence, the CBG extracted from carob seeds of the wild Iferhounene variety can be used efficiently in the food industry as a thickener and as a highly targeted drug-delivery system in the pharmaceutical industry as well.
