Research on consumer quality perception is reviewed using the Total Food Quality Model as a structuring device. The relationship between food safety and quality is addressed, and is discussed in the context of research on consumer risk perception. Quality and safety perception is linked to food choice and consumer demand, addressing questions of price perception and the validity of willingness-to-pay measurements. It is concluded that food quality and safety are central issues in today’s food economics, though many research questions remain to be addressed.

Food quality and safety: consumer perception and demand

Modified Jack-knife estimation of parameter uncertainty in bilinear modelling by partial least squares regression (PLSR)

Purpose – The importance of packaging design and the role of packaging as a vehicle for consumer communication and branding are necessarily growing. To achieve communication goals effectively, knowledge about consumer psychology is important so that manufacturers understand consumer response to their packages. this paper aims to investigate this issue.Design/methodology/approach – The paper examines these issues using a conjoint study among consumers for packaged food products in Thailand, which is a very competitive packaged food products market.Findings – The conjoint results indicate that perceptions about packaging technology (portraying convenience) play the most important role overall in consumer likelihood to buy.Research limitations/implications – There is strong segmentation in which packaging elements consumers consider most important. Some consumers are mostly oriented toward the visual aesthetics, while a small segment focuses on product detail on the label.Originality/value – Segmentation var...

Sensory expectations based on product-extrinsic food cues: An interdisciplinary review of the empirical evidence and theoretical accounts

The electronic nose (e-nose) is designed to crudely mimic the mammalian nose in that most contain sensors that non-selectively interact with odor molecules to produce some sort of signal that is then sent to a computer that uses multivariate statistics to determine patterns in the data. This pattern recognition is used to determine that one sample is similar or different from another based on headspace volatiles. There are different types of e-nose sensors including organic polymers, metal oxides, quartz crystal microbalance and even gas-chromatography (GC) or combined with mass spectroscopy (MS) can be used in a non-selective manner using chemical mass or patterns from a short GC column as an e-nose or "Z" nose. The electronic tongue reacts similarly to non-volatile compounds in a liquid. This review will concentrate on applications of e-nose and e-tongue technology for edible products and pharmaceutical uses.

The problem of balancing out the effect of order of presentation and the carryover effect of a preceding sample over a series of presentations of the same set of samples is addressed. A series of designs developed by Williams (1949) are used. The method of calculation is given. Tables containing about 50 consumers of each design for presenting from 4 through to 16 samples are given.
