Abstract

Factors that influence the acceptability and preferences of consumers have been perceived as sensory attributes, such as color, appearance, flavor, and texture. Understanding which attributes are most important for overall liking would be helpful to establish meaningful criteria for product grading. Thus, in addition to the overall chemical and sensory qualities, it is important to appreciate which sensory attributes make a product pleasant or unpleasant to a consumer. In this context, the aim of this study was to evaluate the sensory attribute that contributes most to the overall liking by a gamma regression model using different formulations of mixed fruit jams made with Brazilian Cerrado fruits. Based on the proposed model, we concluded that appearance was the most important predictor of the overall liking of the assessors.

Highlights

Sensory properties are important factors in the determination of liking, and among the factors that influence the acceptability and preferences of consumers are sensory attributes, such as color, appearance, flavor, and texture (Concas et al, 2019)
A gamma regression model is considered in which the mean of the response variable depends on the values of the regressor variates according to an exponential link function, which is an alternative to consider for variables that seem to be highly skewed

Summary

Introduction

Sensory properties are important factors in the determination of liking, and among the factors that influence the acceptability and preferences of consumers are sensory attributes, such as color, appearance, flavor, and texture (Concas et al, 2019). Moskowitz & Krieger (1995) investigated which sensory attributes are related to the acceptability of a product by consumers and whether all sensory attributes (flavor, appearance, etc.) have equal weight or have different weights in consumer preference. According to Ritvanen et al (2005), in addition to the overall chemical and sensory quality, it is important to appreciate which sensory attributes make a product pleasant or unpleasant to consumers. RICH), marolo (Annona crassiflora Mart.), jenipapo (Genipa americana L.), sweet passion fruit (Passiflora alata Dryand), and soursop (Annona muricata L.) stand out
