Abstract
This work was conducted to study the quality of frozen fruit pulps of cashew apple, yellow mombin and acerola produced by enterprises from Paraiba and Pernambuco States (Brazilian northeastern region), in order to verify if they are according to Brazilian regulatory laws. The mean values for pulps from both states were: a) cashew apple: pH 4.11; soluble solids = 9.8°Brix; acidity in citric acid = 0,39%; reducing sugars = 5.74%; ascorbic acid = 162.89mg/100g. b) yellow mombin: pH = 2.50; soluble solids = 7.5°Brix; acidity in citric acid = 1.09%; reducing sugars = 2.70%; ascorbic acid = 8.87mg/100g. c) acerola: pH = 3.05; soluble solids = 6.50°Brix; acidity in citric acid = 1.04%; reducing sugars = 3.20%; ascorbic acid = 989.51mg/100g. The result revealed that 68.2% of yellow mombin pulp samples and 59.1% of cashew apple pulp samples were found in disagreement with the QIS juice of these fruits. Concerning to acerola pulp, 40,7% of samples were also in disagreement with the required standard, according to Brazilian legislation. Such findings indicate the necessity to set up QIS for yellow mombin and cashew apple pulps in order to offer good quality products to consumers.
