Avaliação sensorial, intenção de compra e físico- química de licor de pinha (Annona squamosa, L.)

Abstract

The fruit of Pine cone (Annona squamosa, L) is rich in vitamins, minerals, fibers, phytochemicals and besides containing anti-neopláica substance. The cone is usually consumed Natura, but can be processed in the form of liqueur, juices, sweet ice creams and among others is a good alternative for the processing and use of fruit and appreciation of the culture of each region. The objective of this work was to perform sensory evaluation and physicochemical characterization of pine cone liqueur (Annona squamosa, L.) with potable ethyl alcohol of agricultural origin, as a consequence, to evaluate: chemical quality and sensory acceptance. The formulation was made in the proportions of 1.0 kg of pine cone for 1.0 L of alcohol, 0.8 kg of pine cone for 1.2 l of alcohol, 1.2 kg of pine cone for 0.8 l of alcohol and 1.4 kg of pine cone for 0.6 l of alcohol. The syrup with 50% sugar was added to the liquor in the ratio of 1.0 kg of syrup to 50 brix for each liter of infusion. Sensory analysis was also applied through the hedonic scale test to estimate the aroma, flavor, color, and the purchase intent test. The group of takers consisted of 54 people of both sexes. The most accepted sample (1.2 kg of pine cone for 0.8 L of alcohol) was made physicochemical analysis, with three replications: PH (in potentiometer), total acidity, fixed and volatile, alcoholic content, total sugars, reducers, non-reducers, soluble solids and Instrumental color. For the results the values found in the physicochemical analysis were: PH 5.67; Total acidity 0.900 g/L of (citric acid); volatile acidity 0, 124g/L (acetic acid); Fixed acidity 0.775 g/L (citric acid); Alcohol content 22.6 ° GL; Soluble solids (Brix o) 28.63; Total sugar 196.7 g/L (glucose); Sugar Reducer 104.1 g/L (glucose); Non-reducing sugar 83.3 g/L (sucrose) and colorimetric analysis tended to yellow. The attributes with higher scores were statistically the flavor. Concluding that the Pine cone drink was well accepted in the tests of global acceptance and purchase intent. The purchase intent value was positive, demonstrating the viability of the product.
