Semi-solid fibre syrup for sugar reduction in cookies
No full textSince sugar reduction is a pillar of the international nutritional guideline, the food industry is constantly looking for new ingredients able to replace sugar technological functionality while satisfying the consumer's request for clean label. Based on corn (Zea mays) dextrin and seed coats of chickpeas (testa of Cicer arietinum seed), a fibre syrup was tested as bulking agent in cookies to reach 30% and 50% sugar reduction. Cookies were characterised for their physicochemical, rheological and sensorial attributes. Fibre syrup addition did neither hinder dough workability nor require changes in cookie production procedure. The use of the fibre syrup permitted to partially preserve the structural strength of cookies and increased their red colour index. Moreover, the fibre syrup use allowed to obtain sugar-reduced cookies qualified for ‘reduced in sugar’ and ‘high in fibre’ nutritional claims
Strawberry ripple sauce: A semi-solid fibre syrup to reduce sugar content
No full textA consumer-recognized fibre syrup was used as bulking agent in a sugar reduction reformulation strategy of a strawberry ripple sauce, in order to satisfy the consumer needs of healthier and clean label products. Three sugar reduced recipes of ripple sauces (by 30 %, 50 % and 70 %) were developed and characterized together with a full sugar counterpart. The technological functionality of the fibre syrup was tested analysing the ripple sauces during 60 days of storage at two temperatures (5 °C and 25 °C) considering their physicochemical, stability, rheological and sensorial features. The use of the fibre syrup increased the water activity and the moisture content of the reformulated ripples; however, no water syneresis occurred during storage in these samples. The consumer acceptability of ripples in which sugar was reduced by 30 % furthermore confirm the possibility to use the fibre syrup as sugar substitute in high sugar products. The industrial scalability was confirmed for the ripple sauce in which sugar was reduced by 30 % as it resulted similar at rheological and sensory level to the full sugar counterpart also during storage
A fibre syrup for the sugar reduction in fruit filling for bakery application
Full text linkClean label ingredients able to reduce sugar in food are highly demanded by the food industry. A new fibre syrup based on corn (Zea mays) dextrin and seed coats of chickpeas (testa of Cicer arietinum seed) has been used to formulate reduced-sugar fruit fillings. Three reduced-sugar (by 30, 50 and 70%) recipes were developed starting from a standard formulation, in order to reach the “reduced in sugar” and “high in fibre” label claims. Physicochemical and sensory properties of the fruit fillings were assessed during 180 days of storage at two different temperatures (5 °C and 25 °C). Increased firmness, adhesiveness, consistency coefficient (K, flow behaviour), bake stability and colour differences have been observed in reformulated recipes with increasing fibre syrup content if compared to the control. Storage decreased bake stability and induced darkening of the product in all samples. 30% sugar-reduced filling were the most appreciated by consumers, and not distinguishable from the control. Overall results confirmed the syrup technological functionality when used to obtain a 30% sugar-reduction

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
