The lack of data on consumer refrigeration temperatures and storage times limits our ability to assess and manage risks associated with microbial hazards. This study addressed these limitations by collecting data on temperatures and storage handling practices of chilled foods. Consumers from 102 households in Uppsala, Sweden, were instructed to purchase seven food items (minced meat, fresh herring fillets, soft cheese, milk, sliced cooked ham, vacuum-packed smoked salmon, and ready-to-eat salad) and to store them using their normal practices. They were interviewed the next day, and food temperatures were measured. In general, there were no significant relations between temperature and characteristics of the respondents (e.g., sex, age, education, age of the refrigerator). Mean storage temperatures ranged from 6.2 degrees C for minced meat to 7.4 degrees C for ready-to-eat salad. Maximum temperatures ranged from 11.3 to 18.2 degrees C. Data were not significantly different from a normal distribution, except for ready-to-eat salad, although distributions other than the normal fitted data better in most cases. Five percent to 20% of the food items were stored at temperatures above 10 degrees C. Most respondents knew the recommended maximum temperature, but less than one fourth claimed to know the temperature in their own refrigerator. Practical considerations usually determined where food was stored. For products with a long shelf life, stated storage times were different for opened and unopened packages. The current situation might be improved if consumers could be persuaded to use a thermometer to keep track of refrigerator temperature.
Cereal grains are the main dietary source of energy, carbohydrates, and plant proteins world-wide. Currently, only 41% of grains are used for human consumption, and up to 35% are used for animal feed. Cereals have been overlooked as a source of environmentally sustainable and healthy plant proteins and could play a major role in transitioning towards a more sustainable food system for healthy diets. Cereal plant proteins are of good nutritional quality, but lysine is often the limiting amino acid. When consumed as whole grains, cereals provide health-protecting components such as dietary fiber and phytochemicals. Shifting grain use from feed to traditional foods and conceptually new foods and ingredients could improve protein security and alleviate climate change. Rapid development of new grain-based food ingredients and use of grains in new food contexts, such as dairy replacements and meat analogues, could accelerate the transition. This review discusses recent developments and outlines future perspectives for cereal grain use.

AbstractPurpose -The purpose of this paper is to investigate the food storage temperature in Swedish household refrigerators, to determine whether students use the best-before-date label to determine food edibility, and to examine if the study increased the students' interest and knowledge regarding these issues. Design/methodology/approach -In total, 1,812 students, enrolled at 72 Swedish schools, analysed the temperature on different shelves in their family refrigerator using thermometers (Moller-Therm (+0.5/−0.1°C) and instructions provided by their teachers. A questionnaire dealing with the issues of date labelling, food safety, refrigerator storage and food wastage was completed by the teachers. Findings -The temperature at the back of middle shelves was coldest (average 4.8°C; SD 3.1). A relatively high proportion of food items were stored at higher temperatures than recommended. The use-by date had been exceeded for 30 per cent of products, but the students did not rate these as inedible. According to the teachers, the investigation increased interest and knowledge among their students of date labelling, food hygiene, refrigerator storage and food waste. Research limitations/implications -Thermometers were used to measure air temperature on different shelves in the family refrigerator. Data collection was not controllable, as the students measured without supervision. Practical implications -The teachers reported that the study increased interest and knowledge among their students regarding cold food storage. Social implications -This way of teaching food safety would meet the aim of generally increasing food safety knowledge in society, which might have a positive impact on public health. Originality/value -The use of school-children as data collectors to determine refrigerator temperatures in private homes is a novel approach, which was an efficient way of teaching relevant facts as well as collecting large amounts of data.
