Effect of different ingredients contents on physical, physicochemical and sensory properties of the creamy banana marmalade cv. ‘nanica’(Musa cavendishii)

ABSTRACT

Banana is a highly perishable fruit, with a shelf life of 7 to 10 days, and the fruits being in excess or those in non conformity to be consumed are used to produce marmalade; and it is an interesting economic alternative. This study evaluated the effect of different ingredients on the physical, physicochemical and sensory properties of creamy banana marmalade. An incomplete factorial design (24-1) with two levels of four factors (pulp/sugarratio, pectin concentration, added amount of acid and sorbate concentration). The sensorial acceptance of marmalades was evaluated using a 9-point hedonic scale, and the purchase intention by employing a 5-pointscale. The analyzed variables mostly affecting the parameters were the pulp/sugar ratio, the added amount of acid and the sorbate concentration, due to their reaction with the marmalade components. The formulation 2 was preferred by consumers because of the firmest texture and the intensified yellow color.
