Quality of coconut water sold in the hinterland of Paraíba and Ceará: Physical-chemical, microbiological and sensory evaluation of green dwarf coconut water sold in the Paraíba and Ceará hinterlands

Coconut water is considered a natural isotonic rich in nutrients and highly attractive due to its nutritional value and taste. Its consumption has increased considerably especially in industrialized form in the Northeast of Brazil where the largest plantations of the green dwarf coconut palm are concentrated making it essential to evaluate its quality. The aim of this study was to evaluate the physico-chemical microbiological and sensory quality of industrialized coconut water samples sold in the sertão region of Paraíba and Ceará. High bacterial counts were detected in the samples analyzed stored under refrigeration thus possibly indicating the use of contaminated raw materials flaws in processing distribution and/or storage which are directly related to the unsatisfactory time/temperature binomial. The values found for moulds and yeasts are considered high characterizing coconut water as unfit for consumption. According to the results it is essential for the industry to implement and monitor Good Manufacturing Practices for those who bottle and sell coconut water in this region.
