Investigating processing practices and microbiological quality of minimally processed vegetables in Brazil. Braz J Microbiol 2024; 55:1635-1646. [PMID: 38472699 PMCID: PMC11153469 DOI: 10.1007/s42770-024-01275-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Accepted: 02/05/2024] [Indexed: 03/14/2024] Open
Abstract
Minimally processed vegetables (MPVs) are marketed as convenient and healthy choices for consumers. However, the absence of post-commercialization treatments raises concerns about their microbiological safety. This study investigated the processing practices of 28 Brazilian MPV plants and compared the microbiological quality of these products with fresh counterparts in the city of Sao Paulo, Brazil. Through cluster analysis, the processing plants were categorized into two groups: group 1 (nineteen plants) primarily uses chemical substances in the washing step, while group 2 (nine plants) avoids chemical use but employs similar rinsing practices. Microbiological analysis of 100 samples (49 unprocessed and 51 MPVs) revealed no significant differences in microbial group counts (Enterobacteriaceae, coliforms, and E. coli) between the in natura (unprocessed) and MPV products. However, the prevalence of E. coli was higher in natura vegetables than in MPVs. The results indicated the presence of Salmonella DNA (from either dead or live cells or residual DNA) in 4 samples (3 in natura and 1 MPV) using conventional PCR, suggesting the presence of the pathogen in these samples. Listeria monocytogenes was absent, but Listeria innocua was found in two unprocessed products. The study suggests that certain MPVs have microbial loads similar to unprocessed vegetables, potentially serving as carriers for pathogen transmission. These findings emphasize the importance of understanding practices in Brazilian MPV processing plants, informing the implementation of control measures to improve MPV safety and shelf-life, thus ensuring microbiological safety.

Abstract
Crisis periods such as the COVID-19 pandemic may reshape consumers’ behavior and challenge all food chain actors on how to assure and better respond to consumers’ needs and wants. This study aimed to reveal the main concerns of consumers related to food consumption during the COVID-19 pandemic and to identify factors that may influence their behavior. An online survey was performed among 859 Romanian consumers. The Principal Component Analysis revealed five factors: ecofriendly, socio-economic aspects, food waste, plant-based food, and easily accessible food, which affected consumers’ food behavior during the COVID-19 pandemic. It was noticed that females tended to be more preoccupied with the socio-economic aspects and food waste components, compared to males. At the same time, older people were more concerned about the ecofriendly, socio-economic aspects and health concerns, compared with the younger group, the differences being statistically significant. These insights provide information on crucial aspects that shape consumers’ behavior during crisis periods.

Abstract
The purchasing behaviors of university staff (n = 188) and their use of nutrition labels in making food choices were investigated by an online survey. The age of the participants significantly impacted their purchasing behaviors. This effect was not observed with other sociodemographic characteristics studied (level of education, gender, employment status and ethnicity). The impact of age on the extrinsic factors affecting food choice (personal preference, previous knowledge, convenience, religion/beliefs) and intrinsic factors (quantity, country of origin, method of preparation/serving, fat, salt, protein and added sugar contents) were further explored. The use of nutrition labels among different age groups when buying for the first time was significant for breakfast cereals and fruit juices.

Abstract
A conscious approach to the issue of food traceability on the part of consumers is essential for making rational food purchases, which in turn contributes to sustainable consumption and globally, is an element of sustainable development. The study aims to assess the changes in consumers' buying behaviors in the context of food traceability before and during the COVID-19 pandemic, as well as the impact of sociodemographic factors on those changes. Therefore, an online survey was conducted on a sample of 1000 respondents who were Polish food consumers. The study covered aspects related to the traceability of food by consumers before and during the pandemic. The results allowed for positive verification of the H1: Polish consumers attitudes related to food buying process changed during the COVID-19 pandemic. The results didn't allow for fully positive verification of the H2: Sociodemographic factors significantly influence Polish consumers attitudes to the food shopping during COVID-19 period compared to pre-pandemic period. The significant influence was supported in almost all (in 6 out of 8) analyzed aspects in case of age, education, and place of residence. However, in case of gender it was confirmed only in terms of two out of eight aspects: choosing product of national origin and using the online form of ordering purchases.

Abstract
Objectives This research aims to explore the factors motivate consumers to eat game meat during a multi‐state disease outbreak. Methods It proposes a segmentation of consumers based on their attitudes toward and reveals the consumers' food beliefs that motivate their actions. Three segments of game meat consumers were identified: identity seekers, health seekers, and taste seekers. Results A survey of the potential impact that the COVID‐19 crisis has on these three clusters' future food choices showed that the identity and health seekers are more open to a change in food choices. However, the taste seekers are less likely to be influenced by external factors. Conclusions This research indicates that for the policymakers, the key is to take game meat consumers as an effective intervention entry point. It is crucial to facilitate healthy food choices and to promote socially‐ and culturally‐appropriate food beliefs by improving public awareness of the risks of game meat, and invest in organic food. Research Implications This research provides new insights into the food beliefs of game meat consumers via motivation‐based segmentation. This research aims to explore the factors that motivated consumers to eat game meat during a multi‐state disease outbreak that was related to the practice of game consumption.

Exploring the Impact of COVID-19 Pandemic on Eating and Purchasing Behaviours of People Living in England. Nutrients 2021; 13:nu13051499. [PMID: 33946799 PMCID: PMC8146722 DOI: 10.3390/nu13051499] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Revised: 04/27/2021] [Accepted: 04/27/2021] [Indexed: 12/25/2022] Open
Abstract
Consumers' eating habits have changed significantly due to the anxiety and boredom from the reported cases and deaths of COVID-19, the change in work patterns, controlled food shopping, and the inability to meet loved ones during the lockdown. The magnitude of these changes in the eating behaviours and purchasing habits of consumers varies across different groups of people. This study provides empirical evidence of the effects of COVID-19 on the eating and purchasing behaviours of people living in England, which was assessed based on sociodemographic variables. A total of 911 participants were recruited by a market research company, while only 792 useable responses were included in this study. The participants, aged between 18 and 91 years, completed an online questionnaire, and the data were analysed using ordinal regression. Data were collected between October and December 2020. Male participants constituted 34.60%, females 63.89%, and others (other gender and those who prefer not to declare their gender) were 0.63%. The majority of participants' ages fell into the ranges of 23-38 and 39-54. Participants aged 23 to 38 years had the greatest effect of COVID-19 on their purchasing decision of healthier foods, while participants in the age groups 55-73 and 74-91 were least affected. The amount of foods purchased during the pandemic decreased with increasing age. The amount of foods purchased by students, people in employment, and people from minority ethnic groups were greatly affected by the pandemic. All participants who stated that taking food supplements is not important during the pandemic were from the White ethnic group. The effects of the pandemic on purchasing healthier foods were greater in younger generations and participants in full- or part-time employment than participants who were retired and who were aged above 55. The participants with higher educational qualifications and those from minority ethnic groups were also more affected by the pandemic. We suggest further studies to monitor any changes in the effects of the ongoing COVID-19 pandemic on the eating and purchasing behaviours of consumers.

Abstract
The present study explores when consumers recognize the high sugar content of fruit juice and refrain from choosing it for themselves or their families. Fruit juice may be typically perceived as a healthy drink, despite its often high sugar content. We investigate the role of salience of sugar information and enjoyment and responsibility goals in perception and choice of fruit juices. We argue that sugar information needs to be salient to prevent this health halo effect, but that consumers also need to be in a motivational state that promotes processing of this information. In three experiments (N = 801), we manipulate the salience of the sugar content using a salient sugar label (or no explicit sugar label) as well as the activation of different goals (to enjoy versus to be responsible, in the context of choices for self versus significant others). Utilising a newly designed fictitious juice brand, salient sugar labels are effective in significantly raising awareness of sugar content in study 1. Consumers primed for responsibility consider fruit juice with salient sugar information unhealthier as compared to those primed for enjoyment in study 2. Further, in study 3, parents primed for responsibility perceive fruit juice with salient sugar information as unhealthier and less appealing in comparison to parents primed for enjoyment. The effects of responsibility and enjoyment primes on health perceptions are stronger when people think of responsibility or enjoyment of food in the context of their families rather than themselves. We discuss implications for theorizing, beverage marketing, and public policy.

Abstract
Understanding the drivers of food choice is essential to guide the nutrition interventions and tailor nutrition counseling messages. There is strong evidence from a published study, which demonstrate attention for the need to consider the wide range of drivers during food choice. Due to the large variety of food products on the market, consumers make a multitude of food choice daily. The study aimed to assess major motivational drivers of food choice among randomly selected lactating women aged 15-49 years (423) from Debrebirhan Town using face to face interview. Logistic regression analysis was used to find association b/socio-economic variables and motivational drivers of food choice using SPSS version 20. Candidate variables were selected and transferred using the P- a value of less than 0.25, and AOR was reported. Variables with a P-value less than 0.05 on multiple variable logistic regressions were taken as significant variables. Influences of religion, price, preparation convenience, health value and taste during food choice were responded by above half of women. From logistic regression, 15-25 years' age and self-employed were linked to religious influence in food choice with AOR (95%CI) of 0.09(0.01-0.48) and 4.13(1.4-12.24). Age (15-25 and 26-35 years), education (no, primary and secondary) and being housewife were associated to choosing of foods for their health value with AOR (95%CI) of 0.26(0.12-0.6), 0.37(0.18-0.76), 0.14(0.04-0.42), 0.25(0.13-0.54), 0.33(0.17-0.66) and 2.5(1.23-5). Only family size (2-4 vs.>4 persons) was associated with price concern in food choice with AOR (95%CI) of 0.39(0.21-0.71). Being divorced, husband headed, 7-12 and13-18 month lactation period, 15-25 and 26-35 years' age were related to preparation convenience of foods with AOR (95%CI) of 5.94(1.13-31.33), 0.42(0.18-0.96), 3.26(1.34-7.93), 4.4(1.81-10.72), 0.16(0.05-0.47) and 0.25(0.11-0.59). Self-management approaches by nutrition education and promotion to change eating behaviors of women, increasing supply and price regulation toward healthy foods are recommended.

Abstract
1. The objective of this study was to evaluate specific sensory attributes of chicken meat from different production systems to evaluate the emotional responses related to information available on the packages, as well as to investigate consumers' perceptions regarding this information.2. The survey was conducted using the Temporal Dominance of Sensations analysis, which identified differences in taste and texture between samples belonging to the organic, conventional and natural systems.3. The specific emotional lexicon for chicken meat, defined by the consumers through the EmoSemio questionnaire, provided a list of positive emotions for packages that indicated some type of information about the rearing or feeding system.4. The qualitative data obtained using the Attitude Questionnaire demonstrated that packaging and labelling are not self-explanatory, posing more doubts for the consumer at the time of purchase. It was shown that packaging and labelling were extrinsic attributes that influenced the evaluation and acceptability of products. Besides that, consumers were interested in buying products that attest to animal welfare, provided that the price is attractive.5. Poultry companies can have a greater chance of making their products more attractive if they learn more about the attitude and expectations of the consumer in relation to the products, as well as the importance of the animal welfare attributes that are communicated.

Abstract
Food consumers make decisions primarily on the basis of a product's nutritional, functional, and sensorial aspects. In this context, this study evaluated the persistence in sourdough of a multistrain starter culture from laboratory to bakery plant production and the effect of the starter on antioxidant and rheological properties of sourdoughs and derived bread. Lactobacillus sanfranciscensis B450, Leuconostoc citreum B435, and Candida milleri L999 were used as a multispecies starter culture to produce a sourdough subsequently used to modify two traditional sourdoughs to make novel bread with improved health and rheological properties. Both these novel bakery sourdoughs showed the persistence of L. sanfranciscensis B450 and C. milleri L999, and showed a significantly different lactic acid bacteria (LAB) concentration from the traditional sourdoughs. The novel sourdough PF7 M had a higher phenolic content (170% increase) and DPPH (8% increase) than the traditional bakery sourdough PF7 F. The novel sourdough PF9 M exhibited an improvement in textural parameters. Further research would be useful on the bioavailability of bio-active compounds to obtain bread with improved characteristics.

Abstract
Abstract
In the present study, the physicochemical, textural and sensorial properties of crackerbread (made from rye, maize and wheat flour) and rice waffles, the most popular on the Polish market bread substitutes, were determined. It was shown that values of several mechanical properties of rice waffles, including ultimate fracture force, strain and stress differed significantly from that of crackerbread. Texture profile analysis showed that the highest hardness and springiness was exhibited by rice waffles with sesame seeds and wheat-rye, respectively. The concentration of salt was the lowest in rice bread with sunflower. The most acceptable was the rice bread with sea salt (8.26 in a 9-point scale) and overall consumer acceptance of crispbreads was highly correlated with sensory attribute of saltiness.

Abstract
The objective was to evaluate replacement of sodium erythorbate with a natural antioxidant (oregano extract) on physicochemical and sensory stability of lamb burgers, and determine the appropriate amount. Five treatments were prepared, including control (without antioxidant), sodium erythorbate, and three concentrations of oregano extract (13.32, 17.79 and 24.01mL/kg), based on antioxidant capacity determined using the Folin-Ciocalteu, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) methods, respectively. Burgers containing oregano extract, at the concentration determined by FRAP method, had higher oxidative stability, evidenced by an 80% reduction (P<0.001) in thiobarbituric acid reactive substances, effective inhibition of protein oxidation (P<0.01) and less colour loss during frozen storage. Oregano extract did not impair (P>0.05) consumers' sensory acceptance of the lamb burgers. Under the conditions tested, addition of 24mL/kg of oregano extract could be recommended as a natural antioxidant in lamb burgers.
