Advances in bioeconomy lead to exploitation of wastes for the production of high added-value products. Sometimes, these products face consumer resistance due to a phenomenon known as "neophobia." The aim of this study was the investigation of consumer acceptance/rejection of a novel food product and the segmentation of consumers according to their "food neophobia tendency." A "functional" novel yogurt derived from halloumi whey was chosen as a hypothetical scenario. Data was collected through a survey in typical urban areas in Greece and Cyprus. Statistical analysis revealed three types of "food neophobia tendency" in each study area. Regarding the acceptability of the novel yogurt, consumers are driven by their curiosity about the taste of the novel yogurt, while the main factor of rejection was found in the absence of a health issue.
Mathematical modelling of color, texture kinetics and sensory attributes characterisation of ripening bananas for waste critical point determination
(Elsevier: Journal of Food Engineering., 2016-12) Nannyonga, Stella; Bakalis, Serafim; Andrews, James; Mugampoza, Ediriisa; Gkatzionis, Kostas
It is vital to correlate the instrumental and non-instrumental analyses of food products so as to determine the product waste critical point. Texture and color (instrumental) were determined by a universal testing machine (UTM) and colorimetry respectively to ascertain the kinetics of bananas during ripening. While deterministic, descriptive and ranking sensory tests were employed for sensory attributes characterisation. Seven banana color ripening stages were used for color variation and three temperatures (16, 23 and 30 °C) were used to study the kinetics, L, a, b and ΔE were calculated and axial puncture force, PF determined. Logistic model and first order reaction models were used. The sensory attributes results indicated banana waste critical point from stage 6 while instrumental analyses still indicated a model trend up to stage 7.
Microbiological quality and safety assessment of sun dried Rastrineobola argentea (Mukene) sold at selected landing sites of lake Victoria and peri urban Kampala city markets

Silver fish (Rastrineobola argentea) also locally known in Uganda as Mukene contributes significantly to Ugandan national economy and its value was estimated at $13 million US dollars in 2015. The fish is traditionally dried under direct sunshine on bare ground in unhygienic conditions, which expose it to dust and microbiological contamination. In this study, the microbial load of indicator and pathogenic organisms was determined in Mukene sold at selected landing sites of Lake Victoria and Kampala markets, Uganda. A total of 46 samples were collected randomly from landing sites and markets. The total aerobic counts, total coliforms, Escherichia coli, Salmonella and Staphylococcus aureus were enumerated using standard microbiological methods. The findings showed that Mukene was of low microbial quality for total plate counts, total coliforms, E. coli and S. aureus counts with values ranging from 2.48-8.61 log cfu/g, 0.36-3.09 log MPN/g, 0.36-3.04 log MPN/g and 0.10-6.66 log cfu/g, respectively. Of all samples analyzed, 63% were positive for Salmonella species. As salmonellae and staphylococci are often implicated in incidences of food poisoning, this study suggests that consumption of sun dried Mukene sold at landing sites of Lake Victoria, Uganda, poses a public health concern. There is the need to improve on hygiene during processing, storage and distribution of Mukene in Uganda.
