Preservative Effects of Different Treatments and Their Flavor Acceptability in Cashew Apple and Pineapple Blend Juice

Abstract

The aim of this study is to evaluate the stability of a cashew apple and pineapple blend juice (25:75 v / v). Various treatments were applied, including pasteurization (92 C, 15 min), aqueous extract of ginger (2.5 and 10%) and potassium sorbate (1g/kg). The physicochemical results revealed that the addition of the aqueous extract of ginger caused an increase in the content of ascorbic acid, total sugars, proteins and minerals such as magnesium, potassium, phosphorus and zinc. The microbiological analysis showed lower microbial counts of the treated samples compared to the control. The different treatments could have an antimicrobial effect. The sensory analysis reveals a general acceptability for all the samples formulated. This acceptability value is higher for the sample supplemented with 10% aqueous extract of ginger. With a view to preservation without chemical preservatives while improving nutrient content, the 10% aqueous ginger extract could help extend the shelf life of fruit juice drinks.
