The impact of fat content,production methods and carbon footprint information on consumer preferences for minced meat

Growing concern over the environmental impacts and other credence characteristics of food has resulted in increasing interest in the quality attributes of meat products in Finland. The aim of this study was to provide information on the relative preferences of consumers for minced meat attributes. Using a choice experiment, we examined whether the meat type, method of production, fat content, price and presence of carbon footprint information have an impact on consumer choice. A low fat content was found to have a particularly positive effect on the choice of a minced meat product. The carbon footprint information had a significant impact on the meat type-specific consumer preferences: the popularity of beef products decreased and of pork products increased when the footprint information was presented to the consumers. Six heterogeneous consumer classes were identified with latent class analysis: price-conscious (23% of the respondents), fat content-conscious (23%), ideological but passive (17%), content with conventional (14%), beef-preferring (12%) and method of production -conscious consumers (11%). Consumers were generally willing to pay more for a low fat content, but the relative willingness to pay estimates were largely dependent on the consumer groups: premiums for organic and animal welfare-oriented production methods also existed. These attributes could thus represent good means for differentiating minced meat products. The impact of carbon footprint information on the willingness to pay estimates was relatively low.     

Appropriateness,acceptance and sensory preferences based on visual information: A web-based survey on meat substitutes in a meal context

The aim of this study was to investigate the appropriateness, attractiveness, use-intention and (un)desirable sensory properties of meat substitutes in different dishes based only on visual information. A web-based survey was developed to let consumers assess the use of meat substitutes in different dishes. The survey consisted of 38 key questions with subdivisions and was completed by 251 respondents. Six different dishes (spaghetti, rice, wrap, pizza, pasta salad, and soup) were rated for their appropriateness for the use of meat substitutes. Subsequently, appropriateness, attractiveness, and use-intention were rated based on photographs of the six dishes prepared with meat substitutes that differed in shape and appearance. Respondents also had to indicate (un)desirable sensory properties of meat substitutes for every dish. Spaghetti, rice and wrap were more appropriate for the use of meat substitutes than the other dishes. The most appropriate meat substitute–meal combinations were those that are similar to common Dutch meal combinations (e.g. spaghetti with mince and rice with pieces). Attractiveness and intention scores were in line with the appropriateness scores. Furthermore, we found that current users of meat substitutes and younger respondents gave higher appropriateness ratings. This study demonstrates that appropriateness of meat substitutes in a dish is related to attractiveness and use-intention and that meal context should be taken into account in the development of new meat substitutes.     

Modeling,analysis and continuous improvement of food production systems: A case study at a meat shaving and packaging line

In this paper, we introduce a case study at a meat production company to analyze and improve the throughput of a meat shaving and packaging line. An analytical model has been developed and validated by the data collected on the factory floor. The method is based on an iteration procedure using aggregations. It is shown that the model provides an accurate estimation of line throughput comparing with actual production, with difference around 2%. Then, a bottleneck indicator based on probabilities of blockage and starvation has been used to identify and mitigate the bottleneck machine, which is referred to as the machine that impedes system performance in the strongest manner. The MVAC bubble sealer station is the bottleneck of the system, and reduction of its downtime, in particular, the downtime related to film and zipper changes, can lead to a significant improvement of line throughput. Recommendations are provided to the plant management to implement the changes.
