Avaliação físico-química de preparados sólidos para refresco sabor laranja

Abstract

The solid preparations for soft drinks are industrialized products based on juices or vegetable extract of their origin and sugar, and may be added additives, for the preparation of beverages, and must be added drinking water for immediate consumption. It is quite consumed due to the practicality, besides the great acceptance by children and adults. Research has warned that solid soft drink preparations have an erosive potential for dental tissues because the product is acidic. In this context, the present work has the objective of evaluating the physical and chemical characteristics of six different brands of solid orange flavored soft drink preparations, which is the most commercialized in the city of Itaqui-RS and compare them with the specifications indicated on the label. with legislation. Six brands of solid beverage preparation were purchased from three different batches and prepared according to the instructions on their respective labels. Color samples were analyzed by pH, total soluble solids, total sugars, total tilable acidity, dry extract and ash. Through the obtained results it was verified that the color of all the samples independent of the marks and batches presented characteristic color of orange juice. The pH of the samples presented values lower than 3.0, the total titratable acidity ranged from 2.11 to 6.11 g / 100 mL, soluble solids ranged from 2.25 to 2.75 ° Brix between the brands, total sugar obtained between 4.33 and 10.02 g / 100 mL, dry extract content varied between 2.58% and 3.26% and 0.04% and 0.11% ashes. The results suggest that the analyzed samples are in accordance with the information contained in the respective labels, except for the total sugars that presented higher values, but similar to others found in the literature. Based on the results of total sugars and pH, and data found in the literature, it is inferred that the consumption of excess product can harm dental tissues.
