Elaboração de um refrigerante sabor laranja com adição de isolado proteico de soro de leite

Abstract

Currently consumers are very concerned about health, but is not willing to compromise the flavor, so the product must contain ingredients that provide your "wellness", to ensure the benefits of the drink without harming the sensory characteristics. Thus, we developed a type soda drink orange flavor with added protein isolate, whey, bottled in PET (poly (ethylene terephthalate)) and stored at room temperature for 90 days. We attempted to establish a production process simple to manufacture easily adaptable refrigerant in process lines. Were performed periodically during storage at room temperature, physico-chemical, microbiological and sensory product. The analysis results showed good sensory acceptability, standing between the hedonic terms "like moderately" and "like very much". The physical-chemical analysis showed pH 3.53, 11.5 °Bx and 224 mg citric acid per 100 ml of beverage and having the following composition hundredth: 0.501% protein, 88.9% moisture, ash 0.084 and carbohydrate 10,5%. During the storage period the beverage obtained absence of micro-organism. The results showed that this product is stable when stored at room temperature for 90 days. Thus, it is concluded that an alternative beverage prepared in the introduction of whey protein in the refrigerant, thereby becoming a beverage with superior nutritional value and with the same amounts of calories compared with refrigerant and some orange juices found in consumer market.
