Abstract Fermentation using starter cultures has been considered an alternative and economically viable technology for the production of specialty coffees. This type of technology promotes several benefits, such as increased sensory quality, control over the fermentation process, predictability of the final product and added value. Coffee (Coffea arabica L.) samples for this study were collected in Presidente Olegário - MG (2018/19 crop year) in the Cerrado region of Minas Gerais. The effects of natural fermentation and inoculation of the yeast Torulaspora delbrueckii and duration of fermentation (0, 24, 48, 72 and 96 hours) on the sensory and chemical quality (analysis of bioactive, volatile, and organic compounds and fatty acids) of coffee were evaluated. The objective of this study was to determine the effect of fermentation time and starter culture inoculation on the chemical composition of fermented coffees. Fermentation time significantly influenced the sensory description of the coffee beverage, with notes of honey, brown sugar and almond predominating up to 48 hours, for coffees fermented for 72 and 96 hours the notes described were and fruity, winey notes. The chemical composition was primarily influenced by fermentation time. benefits process value Coffea L.

O processo de desenvolvimento de produtos (PDP) é um fator crítico de sucesso no lançamento de um novo produto para atender os requisitos dos clientes. A adoção de um modelo de referência serve como um guia detalhado para auxiliar as organizações na gestão e sistematização do PDP, através da sequência padronizada de etapas que são adaptadas de acordo com o tipo de produto que a empresa desenvolve. O objetivo deste artigo é selecionar um modelo de referência do processo de desenvolvimento de produtos para uma empresa do ramo de autopeças através de um método de auxílio à decisão por multicritério denominado Analytic Hierarchy Process (AHP). O método de pesquisa utilizado foi a modelagem, que diante de seis alternativas, três critérios e julgamento de cinco especialistas resultou na seleção do modelo de Rozenfeld et al. (2006) como o modelo mais indicado para realizar a análise do PDP da empresa objeto de estudo em pesquisas futuras.

The Product Development Process (PDP) is a critical success factor in launching a new product to meet customer requirements. The adoption of a reference model serves as a comprehensive guide to assist organizations in managing and systematization of the PDP, through standardized sequence of steps that are adapted to the type of product that the company develops. The aim of this paper is to select a reference model of the product development process for the auto part sector by establishing an aid to multi-criteria decision known as Analytic Hierarchy Process (AHP). The research method used was modeling, which before six alternatives, three criteria and trial of five experts resulted in the selection of Rozenfeld et al. (2006) reference model as the most suitable model to analyze the company's PDP selected as object of study in future research.
