Abstract

Purpose

The purpose of this paper is to investigate the ability of the computer vision system (CVS) to evaluate the colour of poultry meat. The advantages of the CVS over traditional methods were also explored.

Design/methodology/approach

The research was carried out on m. pectoralis major samples of three animals for each of the following four species: chicken, turkey, duck and goose. The total colour difference (ΔE) and the degree of difference of hue, chroma and lightness between the methods were calculated. In addition, a trained panel of 14 people was used to carry out three different similarity tests analysed using χ2 one sample test and one-way ANOVA. The correlation coefficient between CVS and colourimeter measures was evaluated using the Spearman rank correlation test.

Findings

The total colour difference (ΔE) between the methods employed was so large that the generated colour(s) could be considered more opposite than similar. The CVS-generated colour chips were more similar to the sample of the meat products visualised on the monitor compared to colourimeter-generated colour chips in all (100 per cent) individual trials performed. The use of the colourimeter for colour evaluation of lighter coloured poultry meat (chicken and turkey) was unrepresentative.

Practical implications

In this study, a CVS was developed to measure the colour of poultry meat as an alternative to conventional colourimeters.

Originality/value

The research has demonstrated that the use of a CVS should be considered a superior alternative to the traditional method for measuring colour of chicken, turkey, duck and goose meat.

The purpose of this paper is to analyze perceptions of quality in the chicken meat supply chain.

Abstract

Purpose

The purpose of this paper is to analyze perceptions of quality in the chicken meat supply chain.

Design/methodology/approach

This survey covered 74 different farms, slaughterhouses, meat processors, and retailers and 500 consumers, using two methods. From the farm to retail, analysis covered “customer – supplier” viewpoints in different stages of the supply chain. From the consumers to the farms, the quality function deployment method was used. Five houses of quality have been developed using the Delphi method to synthesize the opinions of experts.

Findings

Farm-slaughter comparison shows that final weight at farm gate and animal welfare are the most important quality attributes. The quality aspect important for slaughterhouses and meat processors is the cold chain. Retailers and meat processors highlight the portfolio of various chicken meat products as their most important quality attribute. At the points of sale, shelf illumination and product placement are prevailing.

Research limitations/implications

The results suggest that there are different views on quality by all actors in the supply chain, from quality of chicken meat, food safety and quality of service in retail to profitability and animal welfare.

Practical implications

The paper enhances simplicity in analyzing quality aspects of different types of meat supply chains. This methodology enables a synergy of value chain promotion with other quality development approaches. It also creates possibilities for policy makers to improve competitiveness strategies.

Originality/value

Application of a similar approach to other parts of the food chain could offer a better insight into the transformation of quality.
