Cariogenicity of original and fruit juice-added soy beverages

Abstract

Purpose: To evaluate the cariogenic potential of soy-based drinks available in the Brazilian market. Methods: Three soy-based beverages from different trademarks (Ades®, Mais Vita® and Sollys ®) were evaluated. For each brand, 04 flavors were analyzed (original, pineapple, orange and grape juices). Total Soluble Solid Content (TSSC), Reducing Sugars (RS), Non-reducing Sugars (NRS) and Total Sugars (TS) contents were assessed. Analyses were performed in triplicate. Data gathered underwent analysis of variance (ANOVA), and type I error (α) was set at 0.05. Results: TSSC values ranged between 8.25 and 15.00 °Brix for all samples. There were no differences in TSSC levels between original and fruit juice-added soy drinks. RS have not been detected in any of the original soy beverages. Concerning to the drinks containing fruit juices, Mais Vita ® grape significantly revealed the highest RS levels (P<0.05). For NRS and TS, analyses indicated Ades® and Mais Vita ® original contain levels significantly (P<0.05) lower than the corresponding fruit juice-added drinks. Conclusion: There is no difference in TSSC values between original and fruit juice-added soy drinks and most beverages containing fruit-juices presented higher levels of TS and sucrose when compared to the original soy drink, what might lead to an increased cariogenic potential.
