We consider returns to scale in food preparation as a potential resolution of a puzzle raised by Deaton and Paxson (Journal of Political Economy, 106(5), 897–930, 1998). We clarify the conditions under which returns to scale in food preparation can resolve the puzzle. The key requirement is that foods are heterogeneous in time costs. We then show that detailed food expenditure and time use data...

Book’s topicOne of the most important challenges in modern food analysis is the research of new reliable sample preparation methods. In fact, traditional and automated procedures can ensure reliable results on condition that sample pretreatment methods are fast, accurate, precise, and able to maintain the integrity of extraction processes. The book New trends in sample preparation techniques fo...

Food communicates information, and food meaning depends on the social context in which food is found. The mode of preparation and consumption of food also expresses some cultural values. There is a high complexity of food behavior. For instance, consumers are affected by primary and secondary brand associations. Consumers are not all the same but they all need balanced food information, and to ...

This study collected data on food workers’ self-reported food safety practices and beliefs about factors that impacted their ability to prepare food safely. Eleven focus groups were conducted with food service workers and managers in which they discussed their current implementation of seven food preparation practices (handwashing, hot holding, etc.), and the factors they believed impacted thei...

Background: Malnutrition resulting from inappropriate and ineffective childhood feeding remains a significant public health concern especially in developing countries, where poor child feeding practices exert serious negative impact on health outcomes. This qualitative study explored mothers’ perception about complementary feeding, mothers’ hygiene and food safety measures, food storage, and pr...

Foodstuffs analysis is very important due to population growth and increasing consumer demand for safety and nutritional excellence. The Analysis of different compounds in foodstuffs is so difficult without using sample preparation techniques. Traditional techniques require large amounts of toxic organic solvents. As a result, they are not only expensive but also environmentally unfriendly and ...

either a college degree in biological sciences or extensive related work experience. To become certified as applicators, technicians must pass an additional set of category exams. Depending on the State, applicators must attend additional classes every 1 to 6 years to be recertified. Applicators with several years of experience often become supervisors. To qualify as a pest control supervisor, ...
