Red lentil pasta quality and in vitro digestibility modulation by means of processing conditions
No full textPulse pasta has, in recent years, gained the interest of consumers and food manufacturers and a deeper understanding of the the effects of flour types and pasta processing on its physical and nutritional characteristics has become a priority. This work investigates the effects of red lentil flour type (raw or pre-cooked), pasta extrusion pressure (i.e. 80 and 125 bars), and drying temperature (i.e.,50 and 80 degrees C) on pasta quality and in vitro nutritional digestibility. A significant reduction in cooking loss was found in pasta extruded at high pressure and dried at high temperature (80 degrees C), while all pasta had acceptable cooking quality in terms of length, thickness and weight gains. More slowly digestible starch was found in pasta dried at high temperatures, while less rapidly digestible and more resistant starch was present in pasta extruded at high pressure. In vitro starch digestibility can be effectively reduced by applying proper processing conditions (i.e. high extrusion pressure) which could be vital for designing a 100% legume pasta with modulated glycemic response
Pretreated Green Pea Flour as Wheat Flour Substitutes in Composite Bread Making
Full text linkThe present study aimed to assess the impact of substituting wheat flour with three different pretreated green pea flour at different addition levels (10–50%) on fresh bread quality during a 7-day storage period. Dough and bread enriched with conventionally milled (C), pre-cooked (P), and soaked under-pressure-steamed (N) green pea flour were evaluated for their rheological, nutritional, and technological features. Compared to wheat flour, legumes had lower viscosity but higher water absorption, development time, and lower retrogradation. Bread made with C10 and P10 showed similar specific volume, cohesiveness, and firmness to the control, whereas addition levels beyond 10% decreased specific volume and increased firmness. During storage, incorporating legume flour (10%) delayed staling. Composite bread increased proteins and fiber. C30 had the lowest rate of starch digestibility, while pre-heated flour increased starch digestibility. In conclusion, P and N can be considered valuable ingredients for making soft and stable bread
Development of sugar- and fat-reduced pulse cookies with improved predicted glycemic behavior
No full textCookies, a trendy snack, are traditionally characterized by a poor nutritional profile (high sugars and fats, low
protein and fiber). To improve their nutritional profile, standard wheat “pasta-frolla” cookies were reformulated
with 100 % pulse flour (chickpea and lentil), partial sugar reduction with a commercial fiber syrup (Meltec®),
and full butter replacement using a structured fiber-sunflower oil-water emulsion (alone or in conjunction).
Developed cookies had higher protein and fiber contents, reduced sugar (~45 - 50 % reduction), and saturated
fats (~77 - 80 % reduction) and also had a lower predicted glycemic index compared to traditional cookies.
Water activity and moisture content of the cookies were in line with those of the same product category, while
they had a harder texture compared to their full butter counterparts due to the full substitution of butter (alone or
in combination with sugar reduction). Lentil cookies showed slightly lower in vitro starch and remarkably higher
protein digestibility than the control cookie, and the simultaneous application of sugar and fat substitution did
not negatively affect their overall acceptability. The developed products are expected to be a suitable base for the
development of snacks for elderly consumers, who are the population niche that, due to health issues, is most
likely to be interested in this type of cookies
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
