Development of GLM regression models to predict the consumer acceptability of cooked ham based on analytical parameters Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
Due to concerns about meat quality, health, sustainability and animal welfare, the typical Belgian meat products such as cooked ham are being threatened by a negative reputation. To address these concerns, an objective quality assessment tool was developed that could predict the consumer acceptability for a range of sensorial descriptors based on analytical parameters. A total of 28 commercial cooked hams were evaluated by a sensorial panel of ...
Public acceptability of policy interventions to reduce sugary drink consumption in urban Vietnam Universiteit Gent
This study aims to assess the public acceptability of interventions to reduce sugary drinks in Vietnam, identify the key determinants, and develop a classification of consumers. A cross-sectional survey with 263 urban consumers evaluated perceptions of four potential interventions: restricting choice, taxation, nudging, and labeling. Thereby, specific attention was devoted to perceived intrusiveness and (personal and societal) effectiveness, as ...
Effect of lactic acid fermentation of watermelon juice on its sensory acceptability and volatile compounds Universiteit Gent
Fermentation increases food shelf-life but is characterized by changes that affect product's perception. Watermelon juice was fermented with Lactobacillus plantarum (WJ-LP), L. rhamnosus (WJ-LR), L. casei (WJ-LC), L. brevis (WJ-LB) and Pediococcus pentosaceus (WJ-PP). Their sensory characteristics and volatile compounds were investigated by consumers and Headspace Solid Phase Microextraction integrated with Gas ChromatographyMass Spectrometry, ...
Shelf-life dating of shelf-stable strawberry juice based on survival analysis of consumer acceptance information Universiteit Hasselt KU Leuven
BACKGROUNDAccurate shelf-life dating of food products is crucial for consumers and industries. Therefore, in this study we applied a science-based approach for shelf-life assessment, including accelerated shelf-life testing (ASLT), acceptability testing and the screening of analytical attributes for fast shelf-life predictions. Shelf-stable strawberry juice was selected as a case study. RESULTSAmbient storage (20 degrees C) had no effect on the ...
Consumer acceptance of minced meat patties from boars in four European countries Universiteit Gent
A consumer study was performed in four EU countries to further clarify the acceptability of meat with boar taint. In Denmark, France, Italy and Poland, a total of 476 female consumers evaluated 8 meat patties from boars with varying levels of skatole (0.10-0.40 mu g/g fat tissue) and androstenone (0.47-2.00 mu g/g fat tissue), in a pair-wise comparison with patties from castrates. Boar meat patties were always less preferred than the castrate ...
Exploratory Survey on European Consumer and Stakeholder Attitudes towards Alternatives for Surgical Castration of Piglets KU Leuven
Surgical castration of piglets without pain relief is still common practice in many countries. Possible alternatives for surgical castration are application of pain relief or anaesthesia or production of boars (entire males) and immunocastrates. Each of these alternatives faces advantages and disadvantages which may result in different citizen attitudes and consumers acceptability. Understanding which practice is acceptable to whom and why may ...
Convenience foods, as portrayed by a consumer organisation. Test-Aankoop/Test-Achats (1960–1995) Vrije Universiteit Brussel
Food choice, both today and in the past, is driven by a broad range of interacting factors, in which culture is centrally placed. This paper will assess convenience foods by means of a qualitative analysis of comparative product tests done by Belgium's largest consumer organisation Test-Aankoop/Test-Achats, and will focus on the influence of socially and culturally normative values between the years 1960 and 1995. The tests provide a unique ...
Combining untargeted, targeted and sensory data to evaluate food quality changes during storage. A case study on shelf-stable strawberry juice KU Leuven
Nowadays, consumers are paying a lot of attention towards the quality characteristics of food products (e.g. colour, aroma, taste). Upon storage of a food product, its quality characteristics are continuously evolving. A serious decrease in the quality of food products can have a drastic impact on product acceptability by consumers and will result in a food product not being consumed even before the shelf-life date has been reached. To ensure ...
Effect of a health claim on the acceptance of two açaí fruit juices with a low and high a priori overall liking Universiteit Gent
Fruit juices offering health benefits beyond basic nutrition are nowadays highly valued among European consumers. Given its nutritional value and concomitant health benefits, açaí (Euterpe oleracea Mart.) may offer perspectives when aiming at satisfying health-related consumer needs and wants. The present study aims at examining to what extent health information changes consumer responses and acceptance of two açaí fruit juices that have a low ...
