Food safety is an important issue in the whole processes of food utilization and appropriate labelling is very fundamental in guiding consumers’ decisions. This research was carried out to determine perception of consumers on usefulness of food labels, analyse the factors influencing their perception and determine the factors influencing utilization food labels in their food purchasing decisions. The respondents were randomly sampled and interviewed with structured questionnaire. Data were analyzed with Principal Component Analysis (PCA), Ordinary Least Square (OLS) regression and Probit regression model. Majority of the respondents (56%) were older than 23 years and female (65%). Also, many of the respondents were checking for labels on vegetable oil (54%), eggs (48%), milk (56%) and bread (70%). Majority of the respondents were interested in the expiry dates of vegetable oil (66%), eggs (83%), milk (85%) and bread (86%). Time constraint (32%) and uncertainty about the accuracy of the information (33%) were highlighted as constraints to food label utilization. Perception of importance of food labels was influenced significantly (p<0.01) by label desirability for bread and income. Also, utilization of food labels during food purchases was influenced by being married and household income. It was concluded that consumers were aware of food labels and some efforts were being put into utilization of those labels in their food purchase decisions. .Efforts to promote food safety through utilization of labels should be directed at poor households and those consumers that have not married.

Food fraud is a growing problem and happens in many ways including mislabelling. Since lack of consumers’ knowledge about mandatory food labeling information and different types of food fraud may impact public health, the present work assesses consumers’ knowledge about these issues. Principal component analysis was performed to obtain a smaller number of uncorrelated factors regarding the usefulness and confidence of information displayed in food labels and the perception of food fraud. Results indicated that information displayed in food labels is useful, however the way it is presented may decrease consumer interest and understanding. Regarding respondents’ confidence in foodstuffs, over half of them stated that information provided in food labels is reliable. However, a lack of confidence about food composition is observed in those processed foodstuffs such as meat products. Food fraud is recognized by more than half of respondents with a higher perception of those practices that imply a risk to public health than those related to economic motivation. Age and education of consumers influenced the perception of the information displayed in the food labels, their confidence and knowledge about food fraud. Implementation of education programs to increase consumer knowledge about food labelling and fraud is essential. Respondents’ perception results could be use as guidelines by the food industry to improve food label design in order to enhance consumer understanding.

Packaged Food

The increase in relative level of education and the growing middle-class income earners in Nigeria have made packaged food items attractive to consumers. These foods provide handy, nutritious and convenient food for consumers; however, they also come with public health concerns.  From a policy perspective, food labelling can gauge consumers’ response to the safety conditions of packaged food. However, understanding consumers’ awareness and the use of food label information has attracted little research attention in many developing countries in sub-Saharan Africa. In this study, we investigate consumers’ awareness of the use of food safety labels in Lagos state, Nigeria. We used primary data collected using pretested structured questionnaire from 220 food shoppers who bought pre-packaged foods. A two-stage sampling technique was used to select the respondents. Consumers’ awareness and use of food safety information was revealed using descriptive statistics; Ordinal Regression Analysis was used to examine the socioeconomic factors determining the frequency of reading food safety labels. The study therefore recommends that there should be continuous awareness campaigns on the importance of food labels in ensuring safety and food producers should make sure their food labels are legible.

AbstractObjectiveTo determine the ability of consumers to: locate and manipulate food label information; assess the accuracy of nutrient content claims and which health/nutrient claims are allowed; and identify symbols on food labels. Associations pertaining to use and knowledge regarding food label information were also determined for consumers from different demographic and related groups.DesignAn exploratory descriptive study was undertaken, employing a face-to-face survey focusing on demographic information, shopping behaviour, nutrition is important beliefs, label use, label knowledge and label preference and information sources.SettingSelected public locations in Potchefstroom in the North West Province of South Africa.SubjectsRespondents (n 229) complying with set inclusion criteria were recruited through purposive sampling.ResultsThe results indicated respondents’ general health and label awareness, as most of them (>80 %) could locate label information and identify symbols and specific nutrient content claims although only 53 % were able to calculate the number of servings. Nevertheless, an inability was found to assess the accuracy of some nutrient content claims and permissible health/nutrient claims. More educated, younger, Afrikaans- and English-speaking respondents seemed to be more knowledgeable regarding food label information.ConclusionsRespondents who were informed about nutrition were also informed about label information, while label reading practices resulted in label-influenced purchasing decisions. Educational programmes on food labels should start with nutritional background that could be implemented by consumers during label reading and purchasing decisions.

For environmental and business reasons, understanding the consumer behaviour of the young towards green products is very important. Therefore, the main purpose of this study is to investigate the factors influencing green product buying intention and behaviour among young consumers in Saudi Arabia. The study has developed a set of hypotheses utilising the theory of planned behaviour (TPB) as a guiding principle. They were tested based on data collected from 257 individuals through the use of the Partial Least Square (PLS) method. The findings showed that a culture of collectivism was the best way to predict the green purchasing intentions of young Saudis, followed by a willingness to pay, environmental self-identity and peer pressure. Additionally, purchasing intention is a major factor influencing actual green purchasing behaviour.

Colistimethate Sodium

Colistimethate sodium (CMS) is widely administrated for the treatment of life-threatening infections caused by multidrug-resistant Gram-negative bacteria. Until now, the quality control of CMS formulations has been based on microbiological assays. Herein, an ultra-high-performance liquid chromatography coupled to ultraviolet detector methodology was developed for the quantitation of CMS in injectable formulations. The design of experiments was performed for the optimization of the chromatographic parameters. The chromatographic separation was achieved using a Waters Acquity BEH C8 column employing gradient elution with a mobile phase consisting of (A) 0.001 M aq. ammonium formate and (B) methanol/acetonitrile 79/21 (v/v). CMS compounds were detected at 214 nm. In all, 23 univariate linear-regression models were constructed to measure CMS compounds separately, and one partial least-square regression (PLSr) model constructed to assess the total CMS amount in formulations. The method was validated over the range 100–220 μg mL−1. The developed methodology was employed to analyze several batches of CMS injectable formulations that were also compared against a reference batch employing a Principal Component Analysis, similarity and distance measures, heatmaps and the structural similarity index. The methodology was based on freely available software in order to be readily available for the pharmaceutical industry.

Inflammatory Profile

Abstract Background Neuropathic pain (NeuP) is a complex, debilitating condition of the somatosensory system, where dysregulation between pro- and anti-inflammatory cytokines and chemokines are believed to play a pivotal role. As of date, there is no ubiquitously accepted diagnostic test for NeuP and current therapeutic interventions are lacking in efficacy. The aim of this study was to investigate the ability of three biofluids - saliva, plasma, and cerebrospinal fluid (CSF), to discriminate an inflammatory profile at a central, systemic, and peripheral level in NeuP patients compared to healthy controls. Methods The concentrations of 71 cytokines, chemokines and growth factors in saliva, plasma, and CSF samples from 13 patients with peripheral NeuP and 13 healthy controls were analyzed using a multiplex-immunoassay based on an electrochemiluminescent detection method. The NeuP patients were recruited from a clinical trial of intrathecal bolus injection of ziconotide (ClinicalTrials.gov identifier NCT01373983). Multivariate data analysis (principal component analysis and orthogonal partial least square regression) was used to identify proteins significant for group discrimination and protein correlation to pain intensity. Proteins with variable influence of projection (VIP) value higher than 1 (combined with the jack-knifed confidence intervals in the coefficients plot not including zero) were considered significant. Results We found 17 cytokines/chemokines that were significantly up- or down-regulated in NeuP patients compared to healthy controls. Of these 17 proteins, 8 were from saliva, 7 from plasma, and 2 from CSF samples. The correlation analysis showed that the most important proteins that correlated to pain intensity were found in plasma (VIP > 1). Conclusions Investigation of the inflammatory profile of NeuP showed that most of the significant proteins for group separation were found in the less invasive biofluids of saliva and plasma. Within the NeuP patient group it was also seen that proteins in plasma had the highest correlation to pain intensity. These preliminary results indicate a potential for further biomarker research in the more easily accessible biofluids of saliva and plasma for chronic peripheral neuropathic pain where a combination of YKL-40 and MIP-1α in saliva might be of special interest for future studies that also include other non-neuropathic pain states.

Impulse Buying Tendency

A hotel website exclusive discount is widely adopted by major chain hotels to increase the volume of direct bookings. Although the traditional purpose of a discount promotion is to attract customers to the business, this research suggests that a hotel website exclusive price discount can induce consumers’ additional spending. Principles of mental accounting and two thinking styles (analytic vs. holistic) predict different effects of a price discount and the add-on product type by individual thinking styles. A quasi-experiment investigated the effect of an unexpected discount, relatedness of add-on item to a hotel stay, and individual thinking styles on add-on purchasing. The mediating role of impulse buying was subsequently examined using the PROCESS model. The effect of a price discount and the relatedness of add-on item are significant for analytic thinkers, whereas holistic thinkers report higher likelihood to purchase add-on items regardless of relatedness. Holistic thinkers’ likelihood to purchase is enhanced through an impulse buying tendency. The findings provide further evidence for the role of individual differences in response to pricing tactics by suggesting that a price promotion increases add-on purchases for analytic thinkers, whereas promoting a sense of impulsiveness can be more effective for holistic thinkers.

Purpose: Consumers’ use and interpretation of trans fat information on food labels were explored. Methods: Consumers completed an interviewer-administered questionnaire in one of three grocery stores selected purposively to represent geographical location. Data analysis involved examining the relationship of age, gender, grocery shopping habits, household size, and source of nutrition information with awareness, use, and interpretation of trans fat information. Results: Ninety-eight percent (n=239) of participants were aware of trans fat, and most knew of the relationship between trans fat intake and cardiovascular disease. Although the majority of shoppers were aware of the “0 trans fat” nutrition claim on food packages (95%), they were more likely to use the Nutrition Facts panel (60%) to reduce trans fat intake. Men and consumers under age 40 were least likely to be aware of food label information. While most consumers (75%) correctly interpreted the “0 trans fat” nutrition claim and thought foods with this claim could be healthy choices (64%), only 51% purchased these foods to reduce trans fat intake. Conclusions: Nutrition professionals should target messages to reduce trans fat intake at men and consumers under age 40. While general knowledge was good, further education is required to help consumers interpret trans fat information.

Traceability System

Establishing a blockchain food traceability system (BFTS) is increasingly important and urgent to resolve the contradiction between consumers’ intention regarding safe food selections and the spread of polluted foods. Using the advantages of blockchain, such as immutability, decentralization, openness, and anonymity, we can build trusted food traceability systems based on these important characteristics. With reliable information, traceability from production to sales can effectively improve food safety. In this research, multiple models, namely, the information success model (ISS) and the Theory of Planned Behavior (TPB) are formed into a conceptual integrated framework to study the intentions’ influenced factors of BFTS technology for Chinese consumers to help ensure food safety and the quality of Chinese organic food products. A face-to-face questionnaire survey with 300 valid responses was analyzed by Partial Least Square from the Chinese consumers focusing on the organic food products. This study found that the attitude and perceived behavioral control qualities significantly and positively affect the usage intention in adopting BFTS, while the subjective norms are positively but not significantly correlation with the usage intention in using BFTS. The above results will inform suggestions for productors and academics along with implications to promote BFTS’ usage intention.
