Abstract

In recent years, non-alcoholic beers have presented a growth considered satisfactory and exciting for the brewing industry. Such growth is allied to a change in the consumer profile, in addition to changes in traffic laws. However, the consumer seeks a product considered healthier, but as tasty as the original. Thus, this study aimed to identify the influence of the alcoholic factor in sensory profile, through quantitative descriptive analysis and time intensity analysis of Pilsen beer samples. An acceptance test with 120 consumers of beer was performed. A quantitative descriptive analysis was carried out by 11 trained assessors to determine the sensory profile of beers. For identification of influences of alcohol factor in the dynamic profile of alcoholic flavor and bitter taste the time-intensity analysis were realized. The results demonstrate that alcohol factor influences both the quantitative descriptive profile and dynamic profile, in addition the correlations between the quantitative descriptive analysis (QDA®) and hedonic data show that the alcoholic flavor and the alcoholic aroma are attributes that contribute positively to acceptance of samples. In view of the results, studies such as the present are of great importance for the improvement of product quality, directly reflecting a greater acceptance of beer consumers.

IntroductionBeer is a widely consumed drink in the country, Brazil is the third largest global consumer
The brewing sector is considered one of the most important in the Brazil economy
Non-alcoholic beers are relatively new beverages, much less consumed than the alcohol-containing beers; non-alcoholic beverages have shown considerable global growth in recent years, this is related to the use of increasingly sophisticated production methods, in order to meet the expectations of the consumer [1,2]

Summary

Introduction

Beer is a widely consumed drink in the country, Brazil is the third largest global consumer. The consumer market is constantly evolving, to keep up with changing demands, the brewing market constantly invests in the development of new products and the improvement of existing ones [1]. Non-alcoholic beers are relatively new beverages, much less consumed than the alcohol-containing beers; non-alcoholic beverages have shown considerable global growth in recent years, this is related to the use of increasingly sophisticated production methods, in order to meet the expectations of the consumer [1,2]. It is known that the alcohol flavor is a fundamental characteristic for beer and its absence can bring changes in the set of sensory attributes and contribute to rejection of the product [3]. Quality is a fundamental tool to obtain advantages in the market, once it influences the consumer’s behavior and choices, knowledge about the product is required to satisfy consumer needs [4]
