RESUMO

In the view of the importance of food hygiene for consumer health and success in the market, a study was carried out to evaluate the presence of foreign material in frozen pulp of West Indian cherry, guava and mango produced by four companies (A, B, C and D) in Petrolina-PE and Juazeiro-BA. For each fruit pulp, three different lots, each of five samples, were randomly collected from each company. Each sample was analyzed by the flotation method using a Wildman trap flask to isolate any foreign material. Among the contaminant categories, insect fragments and others (fragments of metal, wood, plastic, paint, leaves and twigs; wire; sand and ash) were found in 100% of the samples. While whole insects, insect larvae, eggs and hairs, and feather barbules were present in small amounts in the West Indian cherry, mango and guava pulps, mites were found only in West Indian cherry pulp. Statistical analysis showed significant differences between pulp types in the total number of foreign objects present as follows: 148.7 per 100 g in West Indian cherry pulps; 110.6 per 100 g in guava pulps, and only 3.6 per 100 g in mango pulps. It was also found that companies A and D did not significantly differ (p<0.05) in the incidence of foreign material in their products, though both differed from company B, which had the highest level of contamination, and company C, which had the next highest level. Guava and mango pulps processed by companies A and D did not differ in hygiene quality and were of better quality than the West Indian cherry pulp. Mango pulp had the best hygiene quality, regardless of the company that produced it. The results obtained for the pulps analyzed are not in compliance with current legislation in Brazil
