In Europe fresh-cut fruit and vegetables, is one of the major growing segments in agro-food sector. Current literature reports a limited number of studies about consumers’ preferences towards these products. In particular, it lacks of studies focussed on fresh-cut salads and based on market data. In this paper, a study on consumer preferences towards the main attributes of Italian fresh-cut salads is proposed. More specifically the investigation is focussed on attributes assessable by consumers before purchase such as assortment, tenderness, product preparation and vegetable variety together with brand, size and type of packaging, presence of organic certification, promotion and product price. The purpose of this paper is to evaluate how much Italian consumers pay for those attributes with the aim to understand how much profitable could be different strategies in the sector.

The analysis is based on IRI-Infoscan scanner data, consisting of 881 fresh-cut products. The impact of each attributes on pricing is measured by means of a hedonic price model.

Main results show that, in Italy, fresh-cut salad price is greatly affected by tenderness, product preparation, assortment, brand, presence of organic certification, packaging attributes and vegetable variety.

Findings offer to producers the possibility to set up products by composing the mix of attributes that gives back the highest price. In addition, they provide some insights to define manufacturer’s strategies.

This paper represents a novelty in economic literature because it can be considered an example of consumer preferences analysis towards the different attributes of fresh-cut vegetables based on real market data.

The purpose of this paper is to develop a new salad cream formulation from a mixture of tofu and coconut oil for replacement of egg yolk and soy oil, respectively.

A salad cream formulation mainly composing of edible oil, egg and vinegar was formulated. Ratios of egg yolk and soy oil were replaced by tofu and coconut oil, respectively. The formulated salad creams were determined for pH, color, viscosity, protein and fat. Sensory acceptances of formulated products was evaluated by using a seven-point hedonic scale test and untrained panelists (n=30). The formulated salad creams were stored in a refrigerator for 14 days and determined for pH, color and viscosity.

The results showed that the formulated salad creams using the mixture of 50 percent tofu and 50 percent egg yolk (RE) by weight of egg yolk ratio in control presented 4.25+0.01 of pH which was comparable to control. The highest scores in the sensory test were obtained in the formula using 37 percent coconut oil by weight of salad cream. The formulated salad creams using tofu and coconut oil (REC) presented 4.42+0.03 of pH, 4.25+0.05 cm. of viscosity, and 87.36+0.44 (L), −1.13+0.04 (a), 16.32+0.22 (b) of color values. Protein and fat contents were 4.79 and 27.59 percent (w/w) in the REC, respectively. After storage under refrigerated, pH, color and viscosity of the modified product were less changed.

Replacement of egg yolk and soy oil with tofu and coconut oil in salad creams was feasible. The REC was less changed in its quality both fresh and after storage. It was accepted in sensory evaluation. The REC could prepare at home and being a food choice for consumers.

The purpose of this paper is to evaluate the frequency and antimicrobial susceptibility pattern of pathogens present in ready-to-eat salads available at a local market.

A 100 salad samples were collected aseptically. Each sample (25 g) was homogenized in 225 ml of sterile peptone water and was serially diluted up to 1×106. Dilutions were inoculated on nutrient agar by surface spread plate technique. Aerobic colony count (ACC) was estimated by counting the colonies. Bacterial isolates were cultured on blood and MacConkey agar and identified on the basis of their morphology, culture characteristics and confirmed by API 20E and 20NE. Antimicrobial susceptibility was determined as per CLSI 2014.

ACC range was 1.1×103 cfu/g to 5.8×109 cfu/g. Among these the highest ACC was found in channa chat (4.9×104 to 5.8×109 cfu/g). A total of 127 microorganisms were identified; 73 were gram negative rods (GNRs) and 24 were gram positive cocci (GPC). Among GNRs; Klebsiella spp. (n=18) was the predominant whereas among GPC, Staphylococcus aureus (n=6) were the chief pathogen. Klebsiella spp. showed 100 percent resistance to ampicillin, 89-78 percent to amoxicillin/clavulanic acid and 33 percent to imipenem, however, Enterobacter spp. were resistant to ampicillin (100 percent) amoxicillin/clavulanic acid (77 percent) and imipenem (23 percent). Staphylococcus aureus showed resistance to co-amoxiclav (83 percent) and penicillin (75 percent).

This study revealed that effective control measures must been implemented and respected by throughout the entire food chain and better surveillance studies should be performed at national level to reduce the spread of bacteria by fresh salads.

This paper explore the high prevalence of multidrug-resistant pathogens in different salads and most of the salads were found to be unhygienic for consumption.

Fresh vegetables contain advantageous phytochemical components, making them one of the most significant sources of nutrition. The threat of harmful bacteria still exists because these vegetables are not heated in restaurants before being consumed. Therefore, this study aimed to evaluate the microbial quality of fresh vegetables in restaurants of different levels.

A total of 499 fresh vegetable samples (from sandwiches and fresh-cut vegetable salads) were collected from 3 different types of food service establishment: 201 from international restaurants (IRs), 210 from national restaurants (NRs), and 88 from cafeterias (CAs). The samples were prepared and inoculated on specific growth media. The aerobic mesophilic bacteria (AMB) Campylobacter spp., Staphylococcus aureus (S. aureus), Enterobacteriaceae, Escherichia coli (E. coli) and yeast and molds were counted, and Listeria monocytogenes, Salmonella spp. and Escherichia coli O157 were detected using specialized medium.

High counts of S. aureus, above 3 log cfu/g, suggested that 71.5% of samples collected from NRs and 77.3% from CA were not accepted, whereas 81.6% of samples collected from IRs were accepted. The low population of E. coli, less than 2 log cfu/g, suggested that 99.0, 97 and 92.0 % of samples collected from IRs, NRs and CA, respectively, were accepted. Listeria monocytogenes and Escherichia coli O157 were absent from every sample. One sample was positive for Salmonella spp. in each of the NR and CA sample groups.

RIs adhere to health and hygiene standards better than NRs and CAs, according to the findings of vegetable contamination tests.

This study aims to increase knowledge of the ability of nutrition labels to guide consumer choices in real-life environments.

Food consumption and plate waste data were collected from two self-service restaurants (SSR) with different customer groups over six observation days: three control and three intervention (with nutrition labelling) periods. Study Group 1 consisted of vocational school students, mostly late adolescents (N = 1,710), and Group 2 consisted of spa hotel customers, mostly elderly (N = 1,807). In the experimental restaurants, the same food was served to the buffets during the control and intervention periods.

The nutrition label in the lunch buffet guides customers to eat fewer main foods and salads and to select healthier choices. Increased consumption of taste enhancers (salt and ketchup) was observed in the study restaurants after nutritional labelling. Nutrition labelling was associated with a reduction in plate waste among the elderly, whereas the opposite was observed among adolescents.

The results provide public policymakers and marketers with a better understanding of the effects of nutrition labelling on consumer behaviour. Future studies should further evaluate the effects of nutrition labelling on the overall quality of customer diets and the complex environmental, social, and psychological factors affecting food choices and plate waste accumulation in various study groups.

Listeriosis in animals and humans has been known for over 60 years. Outbreaks in humans have been reported since 1951 but the importance of foodborne transmission has only been realised recently. Listeria monocytogenes is of concern to the food industry because of its ability to grow at refrigeration temperatures and the serious nature of listeriosis. Surveys have shown a widespread incidence of L. monocytogenes in foods and high numbers in certain foods. Hygienic practices in food production are being modified to reduce this incidence, and conditions to minimise the survival and growth of listeria in foods are being determined. Listeriosis is still a relatively rare disease and the majority of people may be resistant, or develop immunity to the bacterium. Because of the fact that a significant proportion of the population is likely to be vulnerable to infection, and the trend towards increased consumption of chilled foods which may have an extended shelf life, it is important to minimise the incidence of listeria in foods.

The purpose of this paper is to estimate respondents’ socio-ecological consciousness (SEC) (knowledge, perceptions, behaviour, habits and feelings) concerning household food waste (HFW) and to identify factors that influence attitude concerning HFW.

Data were collected through a questionnaire survey addressing to 279 residents in Western Macedonia, Greece. A principal component analysis was primarily applied to provide a manageable set of variables relevant to SEC. These variables were analyzed according to their positive/negative influence in SEC through descriptive statistics. Independent samples t-test analysis was employed to examine factors that influence HFW.

Results show that SEC is formed by three main activities: knowledge, perception and attitude. The survey reveals an inconsistency between existing knowledge and problematic perceptions, while the attitude includes neither harmful nor harmless HFW-related activities. A significant finding is that respondents’ age affects food rejection in different consumption stages in a household.

Reliance on self-reported data for HFW that concerns a Greek case study does not allow a generalization of results.

The authors suggest a campaign plan for local bodies. The aim is to enhance respondents’ perceptual abilities and attitude concerning HFW. In order to raise awareness of students and individuals/households, related campaigns could be implemented by educational institutions and other policymakers.

The survey provides information for HFW, a topic not widely examined in Greece, and it is analyzed for the first time on the basis of SEC theory.

Catering business is one of the most prominent and sought-after business investment in Dehradun, given the number of people who have a busy lifestyle. This fact gets more influential as Shugan Group is a catering company that serves the Dehradun market, a valley in the foothills of Shivalik Mountain Range in the state of Uttarakhand. Dehradun enjoys the benefit of being the Capital of Uttarakhand. The catering companies offer a lot of employment while promising delicious food to the stakeholders. Many individuals rely on this sector through food trucks, small shops or through full-fledged catering service providing companies. The group offers innovative and interesting food options for Doonites through their catering services including a lot of regional food options. Traditionally, the catering services in the town comprises handful options to deliver in the form of just food items. The catering services now involve a lot of service elements also including serving of the dishes, ambience and all inclusive of personnel factors. Many individuals assume that mess food is everyday kind of boring food. This assumption definitely holds true throughout the student community who are the major benefactors of the catering services as Dehradun is an education hub in the country. The new food offerings therefore face a lot of change as some of the ingredients definitely are the everyday incorporated ones. In the past couple of years, the catering services concept had gained acceptance for investment because of rise in demand for variety to be provisioned in the offerings as students hold diverse demographical differences. A lot of significance has been given to the likeness of various food options. Shugan Group wishes to inject a new life into the student catering market, leveraging the culinary skills of their handpicked chefs to develop creative new catering options. The advanced skills of chefs, industry insight of the group and an already existing market opportunity will allow the group to showcase its potential. Shugan Group is a start-up company. Marketing is critical to its success and future profitability. It offers creative gourmet for mess catering for a wide range of events and everyday eating options. The basic market need is high quality and creative food options. Having worked in the industry for the past few years and witnessing the dynamic environment including rise in disposable incomes, rise in consumer awareness, consumer’s keenness to eat new delicacies every day and desire to purchase quality food, the group has invested a lot in understanding what the consumers want. The performance of the group has been moderately incremental. After holding qualitative wisdom on the requirements of the market, Shugan Group is currently in the speculative stage in terms of being a caterer. The group wishes to reasonably understand the option that it should consciously adopt in terms of being modest about thinking only of financial benefit, with reasonable expansion every year only for the sake of being financially viable or build a strong brand and start getting people to increase word of mouth thereby bringing organic growth.

This case is about Korean Air Lines’ innovative idea to adopt a policy of vertical integration in catering. Rather than out‐source its in‐flight catering, this airline has moved away from industry norms, and is doing its own thing – literally.

Packed salads are popular in many countries of the world. The purpose of this paper is to assess the energy footprint of these products from farm gate to retail gate, compared with unpacked produces distributed by retailers and farmers’ markets in Italy.

Life cycle assessment served as methodological background, even if the analysis was focused on direct and indirect energy consumption. Three supply chains were analysed: packed (P-S) and unpacked (U-S) sold in supermarkets, and unpacked produce sold locally (U-L). Energy inputs were accounted for processing, packaging, refrigeration, transport, and distribution. Data were collected from available literature and from interviews with key experts in the transformation, packaging, and retail sectors. Energy inputs were computed for 1 kg of finished edible product (kg_p).

Packed salads require an elevated energy input ranging from 16 to 37 MJ kg_p−1. Input energy is mostly required for packaging and refrigeration. By comparison, the U-L chain requires about one tenth of the energy (1.8-2.6 MJ.kg_p−1), but local sold produces attain the best performance with only 0.6-1.2 MJ.kg_p−1, since they do not need processing, refrigeration, and disposable packages. Packed products mainly rely on the availability of cheap fossil fuels and all the sector has significantly suffered after the oil shock of 2008. Increasing energy costs may lead the price of the commodity out of the market.

The paper addresses the subject of energy consumption in a popular sector of processed food to which at present little attention has been paid in the domain of food research.
