Background and objectives Pulse flours are produced by dry grinding pulses. Currently, no standards exist for the particle size of pulse flours. The objective of this study was to investigate how particle size affected the flour and bread‐baking properties of commercially milled pulse flours and those produced using a Ferkar mill. Findings Finer pulse flours tended to have greater starch damage, lower water absorption capacity (WAC), and higher peak and final viscosities. Navy bean flour had a larger particle size distribution, lower starch damage, greater WAC, and lower peak and final viscosities due to presence of hull. Red lentil flour had a larger particle size distribution and higher starch damage than yellow pea flour. Bread made with finer pulse flours had better bread scores and a tighter, less open crumb structure. Bread volume was not affected by flour particle size, nor were the sensory properties of the bread in most cases. Conclusions Particle size affected flour and bread‐baking properties of pulse flours indicating that particle size should be considered when formulating pulse‐based breads. Flours milled from whole pulses will have larger particle size distributions due to the presence of hull. Seed hardness will affect the grinding properties of pulses which will affect particle size and starch damage. Significance and novelty Standardization of particle size for pulse flours would allow for consistency when sourcing flours from different suppliers. However, given that different particle size distributions may be better suited to certain applications than others, it may be more useful if suppliers specify the particle size similar to what is done with oat ingredients.
Background and objectives There is a growing global interest in partially replacing wheat flour with pulse flours in foods, including bread. However, undesirable flavors associated with pulse flours, especially yellow pea flour, have limited their use in foods. Pretreating pulses prior to milling offers a possible solution for improving the flavor of pulse flours. The objective of this research was to examine the effect of oven roasting and Revtech roasting (with and without steam) on the compositional, functional, and bread baking properties of whole yellow peas. Findings Regardless of the roasting method used, a roasting temperature of 120°C resulted in flours that retained good functionality and bread baking properties with less detrimental changes in flour color. Bread made with peas roasted at 120°C also had reduced aroma and flavor properties compared to bread made with untreated peas. Conclusions The strong aroma and flavor properties of yellow peas can be reduced by pretreating the peas prior to milling using conventional oven roasting and Revtech roasting. By selecting the appropriate roasting temperature, flour functionality for bread baking can be maintained. Significance and novelty Roasting is a useful premilling treatment for yellow peas. Reducing the off‐flavors associated with pulses while maintaining flour functionality will allow for greater use of pulse flours in formulating foods.
This article concerns the process by which agrarian land is acquired to build up infrastructure, industries, and various services, as well as that process's relation to the project of economic development. Recent strife in India over land acquisition for the purpose of industrialization is relevant to structural transformation in many developing countries. When trickle down is minimal, the question of compensation for those who lose out in the process of economic transformation becomes vital. The article suggests that most of India's large food production is the result of high net sown area, not productivity per acre. Therefore, allocating a small fraction of this land to industrialization would forego some food production, although this can easily be picked up by higher productivity in the remaining area. Fragmented land-holding patterns, however, prevent such productivity increases, which poses an important challenge.
Background and objectives Although there is growing interest in partially replacing wheat flour with pulse flours in bread, the flavor of pulse flours can limit their use. Heat treating pulse flours, with and without the addition of steam, was examined to determine whether the flavor of split yellow pea flour (SYPF) and whole navy bean flour (WNBF) could be improved without altering flour functionality and bread baking properties. Findings Significant temperature × steam interactions were found for most flour parameters including pasting properties, water absorption capacity (WAC), starch damage, and color. Protein, starch, and flour particle size were altered as were pasting and farinograph properties of the pulse/wheat flour blends. Differences in specific volume, color, and C‐cell properties were more evident in the breads made with the treated WNBFs likely due to the different bread formulation used and the presence of hull in the flour. Conclusions Processing the SYPF and the WNBF at 120 and 140°C with steam improved the aroma and flavor of the bread while maintaining good flour functionality and bread baking properties. Significance and novelty Heating treating pulse flours with the addition of steam successfully reduced the objectionable aroma and flavor characteristics associated with SYPF and WNBF. Eliminating undesirable aroma and flavor properties provides a greater opportunity for the inclusion of pulse flours in foods to enhance their nutritional properties.
Background and objectives Pulse flours can impart off‐flavors limiting their use in foods. The objective of this study was to examine the flour and bread making properties of whole and split yellow peas treated with dry and steam heat used as a premilling treatment. Findings Particle size distributions and pasting properties of flours milled from heat‐treated peas were altered, and starch damage was reduced compared to flours milled from untreated peas. Breads made with flour milled from heat‐treated peas had similar firmness to breads made with flour milled from untreated peas with no change in volume and minimal impact on crumb structure. Changes in crumb color (lower L*, higher a*) were consistent with color changes observed in the flours. Heat treating whole peas produced breads with decreased aroma, flavor, and aftertaste, whereas heat treating split peas produced breads with lower intensities of aroma, flavor, bitterness, and aftertaste and increased acceptability. Conclusions Revtech dry and steam heating of whole and split yellow peas as a premilling treatment successfully reduced off‐flavors with minimal changes to flour and bread making properties. Significance and novelty Heat treating pulses prior to milling offers greater opportunities for incorporating pulse flours in foods.
This paper provides evidence concerning political participation (turnout, awareness, attendance at meetings, campaign involvement, voting) and its relation to local governance in a developing country, based on a rural household survey in West Bengal, India. With the exception of education and immigrant status, we find that reported participation rates varied remarkably little with socioeconomic status. Within villages, benefits disbursed by local governments displayed no relation to wealth, caste, education, gender or political affiliations. In contrast, allocation of benefits across villages by higher-level governments displayed bias against poor and low caste groups; these biases were larger in villages with more unequal landownership and lower participation rates in village meetings. Political support among voters for the dominant Left party was positively correlated with receipt of recurring benefits and help provided by local governments in times of personal need, but not long-term one-time benefits or local public goods provided.
