One third of the food produced in the world is wasted. Bread is one of the most wasted foods both during the distribution process and in households. To use these breads, it is necessary to get to know the properties of the flours that can be obtained from them. The purpose of this work is to know how the type of bread and its zone (crumb or crust) influence the characteristics of the flours obtained from the wasted bread. For this, flours made from the crumbs and crusts of eight different breads have been analysed. Their hydration properties, cold and post-heating rheology and gelling properties as well as the colour of flours and gels have been studied. Bread flours present higher water-holding capacity (WHC) and water-binding capacity (WBC) values and higher elastic modulus (G’) and viscous modulus (G”) values, both in cold conditions and after heating, than wheat flours. However, they generate weaker gels. Crust flours, and the gels obtained from them, are darker than those from crumbs and their gels. In terms of hydration and rheology, pan and wholemeal bread flours are generally lower than other bread flours. These flours also generate softer gels, possibly caused by the dilution of starch with other components. It can be concluded that the properties shown by wasted bread flours allow them to be reintroduced in the food chain as an ingredient in different products.

Abstract Citrus fiber dispersion with different concentrations (5–25 g/kg) was treated by high-pressure homogenization (90 and 160 MPa) for two cycles. The particle size distribution, hydration properties of powders, morphology and rheological measurements were carried out to study the microstructure and rheological properties changes by high-pressure homogenization (HPH). In conclusion, the HPH can reduce the particle size of fiber, improve the water holding capacity and water binding capacity. Furthermore, fiber shape can be modified from globular cluster to flake-like slices, and tiny pores can be formed on the surface of citrus fiber. The apparent viscosity, storage modulus and loss modulus were increased by HPH whereas the activation energy was reduced. The Hershcel–Bulkley model, Carreau model and Power Law mode were selected to evaluate the rheological properties.

<p>Many studies have indicated that biochar could retain water for an extended period of time. Very little has been demonstrated the behaviour of biochar in arid environments where water retention is vital. The United Arab Emirates is one of the warmest countries in the World where farmers enjoy harvesting more crops during winter, however, during summer date palm trees is one of the main sources of food.  About 44 million date palm trees produce approximately 20 Kilograms of palm frond waste per year per tree (which is around 0.88 million tons of date palm biomass annually). This waste is currently sent to landfills. In this study, we proposed that in the arid soil conditions found in the UAE, this date palm waste could be converted to biochar and used to improve the water holding capacity of UAE soils. Therefore, this study aimed to compare the water holding capacity of amendments of date palm frond (DPF) and its biochar in UAE soils in different local weather conditions (winter and summer). A mesocosm experiment was used to assess the treatments at summer and winter temperature conditions. For the mesocosm, there were 6 different biochar and DPF treatments (1%, 3%, 6%, 12%, 15% and 18% biochar or DPF in soil) along with the controls (sharp sand, DPF biochar and DPF). The experiment was divided into 3 cycles with varying modified humidity. The impact of the experimental treatments was assessed using ANOVA. Both biochar and DPF had no significant effect during the first two cycles (wet and dry) but during the third cycle, the DPF had a 1% better water holding capacity than biochar. Given the mass loss of 5.7% during the production of biochar from DPF. It would seem that the best option is simply use collected date palm fronds. Therefore, further investigations are being processed to assess water binding capacity and physiochemical properties of the biochar, DPF and soil. </p><p> </p><p> </p><p> </p><p> </p>

Meat-containing bread with the use of hemp flour has been devised, with the subsequent assessment of its physical and chemical, sensory properties involving the study into the technological indicators of new products. Three experimental formulations for meat-containing bread were developed, which included semi-fat pork, poultry, mechanically deboned turkey, pumpkin pulp, and 8, 10, 12 % of hemp flour. A meat-containing bread from combined raw materials was adopted as control. All samples were evaluated taking into consideration their physical and chemical, technological, and sensory characteristics. It has been proven that the addition of hemp flour to the formulation improved the consumer value of products by increasing the content of protein, fat, and minerals. It was found that the protein content in the developed products was 18.03‒19.53 g/100 g, which is 3.21‒11.80 % higher than that of the analog. The fat content increased by 17.84–56.83 %, which also led to an increase in the calorie content of products. It has been experimentally confirmed that the introduction of hemp flour into bread's minced meat improves the functional and technological indicators of model meat systems. An increase in water-binding capacity was observed, by 13.46‒22.15 %; in water-holding capacity, by 10.34‒21.43 %; in fat-holding capacity, by 17.2‒26.9 %. The combination of semi-fat pork, poultry, mechanically deboned turkey, and hemp flour increases the ductility of the minced meat while reducing the shear stress, contributes to the good forming properties of the minced meat. The sensory analysis of the prototypes showed their high consumer value. The organoleptic assessment and sensory analysis of the prototypes demonstrated high consumer properties of the manufactured products, which makes it possible to recommend them for inclusion in the diets of various segments of the population

The Relationship

Although Japan is the second largest music market in the world, the structure and practices of the music industry are little understood internationally. People overseas need to know how the music business works in Japan so that they can conduct business comfortably. The Japanese music industry has unique features in some respects. First, Japanese record labels remain heavily dependent on traditional physically packaged music although its profitability is much lower than that of digital distribution. Second, full-scale competition in the music copyright management business has just begun. While JASRAC monopolized this market for more than sixty years, the new entrant, NexTone has gradually increased the market share thanks to the frustration experienced by many music publishers and songwriters in their dealings with JASRAC. Third, the relationship between artists and artist management companies is more like an employer-employee relationship than a client-agent relationship. Artist management companies are fully invested in discovering, nurturing, and marketing young artists just the way big businesses handle their recruits. This chapter illuminates practices of the Japanese music industry for an international audience.

Abstract Recent studies on attitudes toward dementia in the United States, such as the World Alzheimer Report 2019, have found that fear and stigma are still widespread among the general public. This may be particularly true in rural communities. In the current study, community-dwelling adults in small Midwestern communities responded to the open-ended survey question, “What do you think could be done to make your community more welcoming for people with Alzheimer’s disease and other forms of dementia?” Participants (N=242) ranged in age from 18-88 (M=40, SD=21). The sample was 68% female, and 61% lived in communities of 50,000-150,000 people, while 39% lived in smaller towns. Most participants (61.2%) did not personally know someone with dementia. Data were collected via paper and telephone surveys. Responses to the open-ended question were analyzed using open, axial, and selective coding. The following themes emerged: greater exposure to individuals with dementia; educational workshops about dementia; more intergenerational programs; greater accessibility of respite care and other services; more fundraising efforts; and community leaders talking about dementia. Responses included, “Have more intergenerational programs that bring together Alzheimer’s patients and children in a positive environment.” “When I was in school, we visited an Alzheimer’s unit. That was a great experience.” “I know what it is, but I don’t know anything else. I wish I was more informed. I don’t know how to help.” These findings indicate that residents of rural communities are motivated to help individuals with dementia, but need more guidance, education, and personal connections/exposure.

In recent years, plants in sandy soils have been impacted by increased climate variability due to weak water holding and temperature buffering capacities of the parent material. The projected impact spreads all over the world, including New England, USA. Many regions of the world may experience an increase in frequency and severity of drought, which can be attributed to an increased variability in precipitation and enhanced water loss due to warming. The overall benefits of biochar in environmental management have been extensively investigated. This review aims to discuss the water holding capacity of biochar from the points of view of fluid mechanics and propose several prioritized future research topics. To understand the impacts of biochar on sandy soils in-depth, sandy soil properties (surface area, pore size, water properties, and characteristics) and how biochar could improve the soil quality as well as plant growth, development, and yield are reviewed. Incorporating biochar into sandy soils could result in a net increase in the surface area, a stronger hydrophobicity at a lower temperature, and an increase in the micropores to maximize gap spaces. The capability of biochar in reducing fertilizer drainage through increasing water retention can improve crop productivity and reduce the nutrient leaching rate in agricultural practices. To advance research in biochar products and address the impacts of increasing climate variability, future research may focus on the role of biochar in enhancing soil water retention, plant water use efficiency, crop resistance to drought, and crop productivity.

Flaxseed oil cake extract (residual from cold-press oil production and rich in proteins and polysaccharides) was evaluated as a potential substrate for the preparation of spray-dried powders with emulsifying activity. Three variants of powders were obtained using different spray-drying process inlet temperatures: 160 °C, 180 °C, and 200 °C. The influence of temperature on physicochemical features (water holding capacity, oil binding capacity, water activity, solubility, color, chemical composition, antioxidant activity, and surface morphology) of the powders was estimated. Additionally, the emulsifying activity of the powders and the stability of oil-in-water emulsions prepared with their various content (0.5%, 1%, and 3%) were determined. Results showed that inlet temperature had significant influence on all physicochemical and functional properties of the powders. Increased inlet temperature decreased solubility and antioxidant activity but increased water-holding capacity, oil-binding capacity, and emulsifying activity. The emulsions prepared with the powder obtained at 200 °C showed the highest stability. SEM images showed the production of relatively spherical particles which were folded or wrinkled with a lot of dentures. This study could open a promising pathway for producing natural and plant-based spray-dried powders for food applications as emulsion stabilizers.

Purpose The purpose of this paper is to explore how African-American women, both individually and collectively, were subjected to both racism and sexism when participating within civil rights organizations. Design/methodology/approach Because of the intersection of their identities as both African and American women, their experiences participating and organizing within multiple movements were shaped by racism and patriarchy that left them outside of the realm of leadership. Findings A discussion on the importance of teaching social studies through an intersectional lens that personifies individuals and communities traditionally silenced within the social studies curriculum follows. Originality/value The aim is to teach students to adopt a more inclusive and complex view of the world.

Gelling properties stability of the Maillard-type and dry-heating egg white proteins (MEW and DEW) were investigated. MEW were prepared by storing sugar-preserved egg white proteins and glucose at 60 °C and 79% relative humidity for 2 days, and DEW were prepared by storing at 80°C in dry state (7.5% moisture content) for 7 days. The results showed that both MEW and DEW have excellent gelling properties. After storage at room temperature for 180 days, gel hardness, spring and cohesiveness of MEW increased by 1.92%, 1.89% and 4.24% respectively, water holding capacity of MEW gel decreased by 1.42%, while storage time had a considerable effect on those of DEW gels. A tight and more uniform network with constant stability in the course of storage was observed in the gel of MEW (500×), while gaps in EWP gel network were larger and the gel texture became looser with storage time. The results demonstrated that gelling properties stability of MEW is better than DEW.

In attempting to present some observations on the kind of information on the Earth’s resources which may be obtained from spacecraft and space satellites, I think I should explain that I speak as a geographer with research interests in the field of biogeography/geobotany where I have been concerned with the use of vegetation in mineral exploration work and in the assessment of land potential for agricultural and other uses. In the course of this work I have come to appreciate major problems of regional or even continental dimensions and have become aware of the great potential offered by suitably equipped Earth resources satellites for providing information which would assist their solution. At the same time I have come to recognize the great contribution which Earth resources satellites can make in the fields of agriculture, forestry and conservation, topographical and geological mapping, hydrology, oceanography, land use and urban planning, to mention but a few. As a setting for my subsequent remarks I would like to state what I believe to be the relative positions of the U. S. A. and the U. S. S. R. on the one hand and this country and certain West European countries on the other with regard to the acquisition of information from Earth resources satellites. America and Russia have led the world in space research. They have the resources, the facilities and the technical know-how for placing spacecraft and satellites in orbit. For the effective development of Earth resources satellites, however, ground control information is essential. Here this country, together with member and former member countries of the Commonwealth possesses a body of people scattered through universities, government departments and organizations, commerce and industry whose firsthand knowledge of remote terrain in many parts of the world is unrivalled. This knowledge harnessed into an Earth resources satellites programme could enable this country to make a leading contribution to the development of the less developed parts of the world and at the same time materially assist the economy of this country.
