Cross-cultural acceptance of a traditional yoghurt-like product made from fermented cereal

BACKGROUND: Akpan is a traditional ready-to-drink fermented yoghurt-like cereal beverage consumed in urban and rural areas in Benin. With the aim of adapting the product to new local and export markets, this work maps African and European consumer preferences for different types of Akpan. RESULTS: A sensory profile of Akpan was created and consumer tests were conducted with 103 consumers of African origin and 74 consumers of European origin. Consumer acceptance was significantly correlated with fermented odour (r=−0.94) and milky taste (r = 0.92–0.97) attributes. Cluster analysis revealed different behaviour by African and European consumers with respect to acceptability of Akpan; European consumers did not like the sour taste and African consumers liked an intense sweet milky taste. CONCLUSION: This study provides information on how Akpan, and other fermented yoghurt-type cereal products, could be adapted to African and European consumer preferences

Impact of Chlorella vulgaris on the rheology of wheat flour dough and bread texture

Modern foods lead to healthier, cheaper and more convenient products to increasingly demanding consumers. Microalgae are an enormous biological resource, representing one of the most promising sources for new products and applications and can be used to enhance the nutritional and technological value of food products. The enrichment of bread with microalgae biomass is a great challenge resulting from its impact on the development of the gluten structure. The addition of Chlorella vulgaris in a wheat flour dough was studied, to evaluate its influence on the dough rheology and bread texture. Microalgae contents from 1.0 to 5.0 g per 100 g of wheat flour were tested and it was observed that up to 3.0 g of microalgae biomass addition, a positive impact on dough rheology and viscoelastic characteristics, with strengthening of the gluten network, was observed. For higher microalgae content, a negative effect on dough rheology, bread texture and flavor was noticed and an acceleration on bread aging was relevant. No impact on the kinetics of yeast fermentation, neither on the time required for fermentation, was induced by the biomass additioninfo:eu-repo/semantics/publishedVersio

Processing of oat: the impact on oat's cholesterol lowering effect

Epidemiological and interventional studies have clearly demonstrated the beneficial impact of consuming oat and oat-based products on serum cholesterol and other markers of cardiovascular disease. The cholesterol-lowering effect of oat is thought to be associated with the β-glucan it contains. However, not all food products containing β-glucan seem to lead to the same health outcome. Overall, highly processed β-glucan sources (where the oat tissue is highly disrupted) appear to be less effective at reducing serum cholesterol, but the reasons are not well understood. Therefore, the mechanisms involved still need further clarification. The purpose of this paper is to review current evidence of the cholesterol-lowering effect of oat in the context of the structure and complexity of the oat matrix. The possibility of a synergistic action and interaction between the oat constituents promoting hypocholesterolaemia is also discussed. A review of the literature suggested that for a similar dose of β-glucan, (1) liquid oat-based foods seem to give more consistent, but moderate reductions in cholesterol than semi-solid or solid foods where the results are more variable; (2) the quantity of β-glucan and the molecular weight at expected consumption levels (∼3 g day−1) play a role in cholesterol reduction; and (3) unrefined β-glucan rich oat-based foods (where some of the plant tissue remains intact) often appear more efficient at lowering cholesterol than purified β-glucan added as an ingredient

Impact of moisture and grinding on yield, physical, chemical and thermal properties of wholegrain flour obtained from hydrothermally treated sorghum grains

The present work evaluates the potential of sorghum with high content of tannins for wholegrain flour production. Two types of mills were used: a roller mill (RM) and a blade (BM) mill. The impact of moisture and grinding on yield, physical, chemical and thermal properties were evaluated. Maximum yield was obtained using a BM with 25% moisture in the grain, resulting in 60.9% versus 28% (g flour g−1 of wholegrain sorghum) for the RM. Grain moisture and milling type affected flour colour and ashes. For both mills, the pasting and thermal properties of flour with grain moisture variation were significantly different from the untreated control sample. By studying the procedures for flour production and quality characteristics, it is possible to produce flour with good physical attributes, which can contribute to the development of gluten‐free foods based on sorghum for the coeliac population.Fil: Acquisgrana, María del Rosario.

Effect of Pulse Flours on the Physiochemical Characteristics and Sensory Acceptance of Baked Crackers.

Pulse flours offer nutritional alternatives to wheat flour in the production of baked snacks due to their high protein and fibre levels and low glycaemic index. In this study, broad-bean (Vicia faba), yellow-pea and green-pea (Pisum sativum) flours were each blended with wheat flour at 40% in the formulation of chemically leavened crackers. The effects of flour type and baking time on the physiochemical properties, sensory acceptability, nutritional composition and antioxidant activity of the crackers were observed in comparison with 100% wheat crackers. Broad-bean crackers had the highest protein content and antioxidant activity (13 g per 100 g DM and 38.8 mgAAE per 100 g DM, respectively). Yellow-pea crackers had the highest fibre content (12 g per 100 g DM). Physical dimensions and colour attributes were significantly affected by pulse-flour substitution. Yellow-pea and broad-bean crackers were significantly preferred by consumers compared to the control, demonstrating the potential application of these flours to improve the eating quality and nutritional profile of crackers

Frailty Assessment in Prospective LVAD Candidates: An International Survey

Introduction The concept of frailty, initially developed in geriatrics, has recently been applied to individuals with heart failure (HF) and is recognized as an essential measure for prognostication of health status and predicting health outcomes Frailty remains highly prevalent, ranging between 56-79% in those undergoing left ventricular assist device (LVAD) evaluation1 and is associated with poor postoperative outcomes.2 Since little is known about frailty assessment and instruments used, this study aimed to evaluate institutional assessment processes of frailty during evaluation and the implications of frailty in LVAD eligibility

Dofetilide initiation in a tertiary medical center: A medication use evaluation.

Presented at the ASHP Midyear Clinical Meeting. New Orleans, LA This evaluation found that adherence to a pharmacist-managed protocol significantly increased dofetilide continuation rates at discharge and six months. Future implementation includes refining the current dofetilide order set, expanding the pharmacist’s role in dose selection, and standardizing documentation and intervention notes to improve protocol adherence

Effect of Microwave Frying on Acrylamide Generation, Mass Transfer, Color, and Texture in French Fries

[EN] The objective of this work was to evaluate the effect of microwave power on acrylamide generation, as well as moisture and oil fluxes and quality attributes of microwave-fried potatoes. Concretely, 25 g of potato strips, in 250 mL of fresh oil (at room temperature), were subjected to three different microwave powers (315, 430, and 600 W) in a conventional microwave oven. Microwave frying resulted in an acrylamide reduction ranged from 37 to 83% compared to deep-oil frying. Microwave-fried French fries presented lower moisture and higher fat content than deep-oil fried potatoes. Concretely, microwave-fried potatoes presented values of moisture and texture more similar to potato chips than French fries, nonetheless with lower fat levels (less than 20 g/100 g wb) and acrylamide content (lower than 100 ¿g/kg wb) at the reference time. This study presents an alternative way of frying to address the production of healthier potato chips.The authors would like to thank the Universitat Politecnica de Valencia for the PhD scholarship given to Mariola Sansano Tomas.Sansano, M.; De Los Reyes Cánovas, R.; Andrés Grau, AM.; Heredia Gutiérrez, AB.
