The use of an observational approach in conjunction with isolation techniques for campylobacter and salmonella detection has facilitated a detailed evaluation of the risk of cross contamination during food preparation. Identification of suspected exposure routes has linked naturally contaminated raw foods with important food‐handling malpractices, contaminated contact surfaces and ready‐to‐eat foods. In a model domestic kitchen, 29 per cent of food preparation sessions resulted in positive campylobacter isolations from prepared salads, cleaning materials and food‐contact surfaces. Typing results showed that specific campylobacter strains isolated from prepared chicken salads were the same as the strains isolated from the raw chicken pieces, indicating microbial transfer during food preparation. Data obtained from this study can be used for exposure assessment, risk management and in the development of consumer risk communication strategies.

The purpose of this paper is to examine the family dinner in Los Angeles County, California, focusing on the role of commercial foods and the time invested in food preparation. Popular media emphasize the increasing use of processed commercial foods in the USA.

A total of 64 dinner preparation and consumption events were videotaped and observed (32 families, two weeknights each). Observations determined the source of food served (restaurant, take‐out, or home‐cooked), the ingredients and dishes in each meal prepared at home, and the time required to prepare it.

The findings in this paper showed that, even when prepared at home, most evening meals included processed commercial foods in at least moderate amounts. Home‐cooked meals required an average of 34 minutes' “hands‐on time” and 52 minutes' “total time” to prepare. Heavy use of commercial foods saved, on average, ten to 12 minutes, hands‐on time but did not reduce total preparation time. Commercial foods require more limited cooking skills and permit more complex dishes or meals to be prepared within a given time‐frame than do raw ingredients. They may also reduce time investment at stages other than meal preparation, such as shopping.

This paper provides a rare glimpse of food preparation and meal consumption behavior on the family level. Most reports on US food habits are based on survey and purchasing data, rather than direct observation of household activities as used here.

The purpose of this paper is to examine food preparation practices of US older adults by assessing their conceptualization of food preparation methods and their routine use of food preparation methods and kitchen equipment.

In total, 17 community-dwelling older adults used cards with names of food preparation methods and cooking equipment items to do one open sort and three closed sorts about: food preparation method classifications; food preparation method use frequency; kitchen equipment use frequency; and essential vs non-essential kitchen equipment. Descriptive statistics, cluster analysis, and qualitative thematic analysis were performed.

Participants classified food preparation methods using multiple dimensions: ways to alter food, inputs, location, timing, and personal behavior. They used a wide range of food preparation methods and kitchen equipment items in routine cooking. The mean number of the 38 preparation methods sorted as used “often” was 16.5±5.0. In total, 15 of the 17 participants reported using more than 20 of the 40 equipment items “often.” The mean number of equipment items identified as “essential” was 21.5±9.3.

Food professionals should consider access to equipment and food preparation skills and preferences when designing products and working with consumers. Addressing gaps in human and material capital may support adoption of food preparation practices.

Food preparation method and equipment use frequency has rarely been examined from the household cook’s perspective. Using card sorts is a novel approach to examining consumer classification of an extensive list of preparation methods and kitchen equipment.

Domestic preparation practices influence the sensory properties and nutritional composition of food products. Information on the variability in actual domestic preparation practices is needed to assess the influence of applied conditions on the sensory and nutritional quality of food. The collection of such information requires a reliable, valid and practical research method. The paper aims to discuss these issues.

Direct in-home observations, observations in a model-kitchen using cameras, and a self-reporting questionnaire were evaluated for reliability and validity, to study domestic food preparation practices by consumers. Broccoli preparation practices by Dutch consumers were checked by these three methods in this research paper.

All three research methods were found to be test-retest, inter-observer, parallel-form reliable; and face, content and concurrent valid. However, the self-reporting questionnaire is the most practical research method that can be administered on a large number of respondents in a short time to capture the wide variations in preparation practices.

Consumers can be assisted on domestic food preparation practices that reach their sensory preferences (e.g. texture, colour) as well as have health benefits on consumption.

The purpose of this paper is to explore reasons for household preparation losses.

Observations of preparation behaviors and semi-structured interviews of nine people were conducted in their kitchens. The data were analyzed through a qualitative data analysis method.

Three types of preparation losses were identified, i.e. possibly avoidable food waste, excessive removals and unintentional losses. Possibly avoidable food waste and excessive removals were generated owing to people’s perception that is in the gray area between edible and inedible, their preferences, lower quality of food, convenience in preparation, lack of preparation skill and knowledge, and lack of concern about preparation losses. Unintentional losses were tiny pieces of food that were left on cooking tools.

As this study’s participants were nine women living in Japan, further research is needed in order to achieve saturation.

Few studies have discussed reasons for preparation losses, and extant studies were based on a diary method and questionnaires. This present study uncovers several new reasons for preparation losses based on interviews and observations of consumer preparation behaviors. These new details would be helpful for campaigns or programs that aim to reduce food losses.

This paper aims to determine the potential for the spread of bacteria from raw meat and poultry during home food preparation to the surrounding kitchen environment, hands and prepared food due to unsafe handling practices, which are predicted by consumers' knowledge, behaviour and attitudes.

The potential for transfer of E.coli and C. jejuni was monitored in a simulated domestic kitchen environment while food preparation was filmed (n=60 respondents). A survey was also administered.

The results of the study show that transfer of bacteria around the kitchen environment and onto prepared meals are predicted by a lack of thoroughly washing contaminated hands, knives and chopping boards both during and after meal preparation. A higher level of perceived importance of correct food handling behaviour is associated with higher levels of educational attainment and age and food risk perceptions are positively associated with age.

The results highlight the importance of promoting preventative measures and the means of employing them specifically to the young and less educated public who do not frequently cook and prepare food.

This paper is the first to include a verifiable audit of consumer food safety behaviour, microbiological sampling of surfaces, food and hands as well as a consumer survey of knowledge, behaviour and attitudes.

Describes a study to measure the quality of service provided by food‐poisoning surveillance agencies in England and Wales in terms of the requirements of a representative consumer ‐ the egg producing industry ‐ adopting “egg associated” outbreak investigation reports as the reference output. Defines and makes use of four primary performance indicators: accessibility of information; completeness of evidence supplied in food‐poisoning outbreak investigation reports as to the sources of infection in “egg‐associated” outbreaks; timeliness of information published; and utility of information and advice aimed at preventing or controlling food poisoning. Finds that quality expectations in each parameter measured are not met. Examines reasons why surveillance agencies have not delivered the quality demanded. Makes use of detailed case studies to illustrate inadequacies of current practice. Attributes failure to deliver “accessibility” to a lack of recognition on the status or nature of “consumers”, combined with a self‐maintenance motivation of the part of the surveillance agencies. Finds that failures to deliver “completeness” and “utility” may result from the same defects which give rise to the lack of “accessibility” in that, failing to recognize the consumers of a public service for what they are, the agencies feel no need to provide them with the data they require. The research indicates that self‐maintenance by scientific epidemiologists may introduce biases which when combined with a politically inspired need to transfer responsibility for food‐poisoning outbreaks, skew the conduct of investigations and their conclusions. Contends that this is compounded by serious and multiple inadequacies in the conduct of investigations, arising at least in part from the lack of training and relative inexperience of investigators, the whole conditioned by interdisciplinary rivalry between the professional groups staffing the different agencies. Finds that in addition failures to exploit or develop epidemiological technologies has affected the ability of investigators to resolve the uncertainties identified. Makes recommendations directed at improving the performance of the surveillance agencies which, if adopted will substantially enhance food poisoning control efforts.

The purpose of this paper is to assess the effect of involvement in food preparation on estimated calorie content, perception of portion size and desirability of the food item.

To test the hypotheses, three between-subjects experiments (one online, two in a laboratory setting) were conducted. Across the three experiments, participants were presented with a food item either ready for consumption (low involvement) or with the individual ingredients in need of assembly prior to consumption (high involvement).

Results showed that when a consumer is involved in the preparation of their food, they perceive the food to be lower in calories and smaller in portion size than when the same food is presented fully prepared and ready-to-eat. In addition, the effect of food preparation involvement on perception of portion size has negative downstream consequences on food desirability, as a smaller perceived portion resulted in a less desirable food item.

To the authors’ knowledge, the results of this research are the first to focus on the impact of preparation involvement on perceptions of the specific product attributes of calorie content and portion size, and the downstream effect on desirability.

Time is a multidimensional entity and research into how we allocate our time is still at an early stage of development. Food shopping and meal preparation are two related activities which involve a significant consumption of time. Reports on research into attitudes to time and investigates three different aspects of people’s attitudes towards food shopping and preparation: an enjoyment of cooking; and a traditional orientation and a modern (role‐sharing) attitude to the linked activities. Identifies two clearly defined groups. No differences between the groups existed on demographic factors such as age, gender, whether the respondent had paid work and housing type. No differences existed in their ownership of time‐saving consumer durables. One group clearly saw mealtimes as significant activities and found cooking enjoyable. It did not matter whether the people in this group were time‐pressured or not ‐ they chose to allocate time to these activities and they differed in their attitudes to time. A substantial group in society still do see food shopping and meal preparation as important activities. Contends that while such individuals may be subject to modern‐day pressures they still appear to organize their time to maintain a traditional perspective. Considers the implications for food retailers and other marketers.

The purpose of this study was constructed a behavioral observation scale for avoiding food waste from the point of view of Chinese cuisine, used as an evaluation tool to examine food waste in the process of food preparation for hospitality students in Taiwan.

The status of food handling in the preparation process was understood through a literature review and interviews. In addition, the indicators that may cause food waste behaviors were established, and the observation and self-evaluation scales of food waste behaviors in the preparation process were developed.

Avoiding water waste, removing excessive edible parts, avoiding waste on seasonings, avoiding cooking for too long and avoiding water stains in the cleaning process were considered by both the observers and the students as items for improvement in the cooking process. The results of this study will help in understanding the intervention in the teaching practice of avoiding students’ food waste behaviors.

This study can only be based on the test results of the current observation behaviors. Meanwhile, many factors need to be taken into consideration, such as the differences in the amount of knowledge students have about food waste, the differences in preparation techniques, and other different factors, which may lead to differences in the research results.

The behavioral observation and self-evaluation behavior scales of “exploring food waste behaviors in the preparation process” were developed and implemented for the current status. The differences between the results of the observation scale and the self-evaluation scale were compared. In addition, the behaviors that may cause students’ food waste were pointed out. Then, the direction of the teaching content was formulated, and the curriculum plan integrating the content of avoiding food waste into teaching was evaluated. Furthermore, the scales can be applied to kitchen staff handling food materials to understand the current situation of their food handling, which can be used as a driving tool for restaurants to reduce food waste.
