Lupin and chickpea-based yogurts as dairy and soy alternatives

The consumption of plant based products as dairy alternatives has been increasing steeply, sustainability and ethical concerns are the major drivers for this diet transition but it can only be achieved if these products meet consumer's acceptance regarding taste and texture. This study compares lupin-based (LB) and chickpea-based (CB) yogurts, with two commercial yogurts from soy and cow milk. To each liter of pasteurized LB “milk” or CB “milk”, obtained from 10% (w/v) of dry whole seeds soaked and cook in water, one commercial soy yogurt was added for the starter cultures for the lactic fermentation. The incubation occurred at 50ºC for 12 to 16 hours. Nutrition composition was quantified for lupin and chickpea and compared to the composition declared on labels of the soy and cow milk commercial yogurts. Viscosity of the four yogurts was measured with a controlled-stress rheometer (Haake MARS III, Germany), equipped with a coneplate geometry in steady shear. Viscoelastic parameters were also determined in oscillatory measurements at low shear stress: first a shear stress sweep was performed to determine the linear viscoelastic range. For all rheological analysis, the temperature was kept at 8ºC and at 20ºC. Texture characterization was also performed using a TA-XT2 (Stable Micro Systems, UK) texturometer, in penetration mode, with a cylindrical probe of 2cm diameter at 20 mm penetration depth at 20ºC. This work contributes to the knowledge of the rheological and textural properties of LB and CB yogurt alternatives to dairy and soy products. Preference tests were performed to evaluate consumer acceptability. These products will be targeting the vegan market, are plant based proteins source and lactose and gluten freeN/

Use of European pulses to produce functional beverages – From chickpea and lupin as dairy alternatives

Consumption of plant based products as dairy alternatives is increasing steeply. This diet transition can only be achieved if these products keep the nutritional value and meet consumer’s sensory acceptance. This work aimed to evaluate the decrease of the “beany” flavour and of raffinose, stachyose and verbascose contents in EU pulse beveragés production, and also the best lactic fermentation conditions of the beverages, towards chickpea- and lupin-based yoghurts, with rheology properties similar to the commercial soy yoghurts. The reduction of “beany” volatile compounds of chickpea and lupin beverages during processing was confirmed through GC–MS analysis. Soaking and cooking processes were effective in removing flatulence sugars with almost 48% loss from the initial content in lupin beverage. The fermentation conditions at 40 ◦C, 12 h and 2% (w/v) of starter concentration evidenced the best viscoelastic structure and flow properties. The lupin yoghurt-type showed a similar gel structure to commercial soy yoghurt.info:eu-repo/semantics/publishedVersio

Social disparities in food preparation behaviours: a DEDIPAC study

BACKGROUND: The specific role of major socio-economic indicators in influencing food preparation behaviours could reveal distinct socio-economic patterns, thus enabling mechanisms to be understood that contribute to social inequalities in health. This study investigated whether there was an independent association of each socio-economic indicator (education, occupation, income) with food preparation behaviours. METHODS: A total of 62,373 adults participating in the web-based NutriNet-Santé cohort study were included in our cross-sectional analyses. Cooking skills, preparation from scratch and kitchen equipment were assessed using a 0-10-point score; frequency of meal preparation, enjoyment of cooking and willingness to cook better/more frequently were categorical variables. Independent associations between socio-economic factors (education, income and occupation) and food preparation behaviours were assessed using analysis of covariance and logistic regression models stratified by sex. The models simultaneously included the three socio-economic indicators, adjusting for age, household composition and whether or not they were the main cook in the household. RESULTS: Participants with the lowest education, the lowest income group and female manual and office workers spent more time preparing food daily than participants with the highest education, those with the highest income and managerial staff (P < 0.0001). The lowest educated individuals were more likely to be non-cooks than those with the highest education level (Women: OR = 3.36 (1.69;6.69); Men: OR = 1.83 (1.07;3.16)) while female manual and office workers and the never-employed were less likely to be non-cooks (OR = 0.52 (0.28;0.97); OR = 0.30 (0.11;0.77)). Female manual and office workers had lower scores of preparation from scratch and were less likely to want to cook more frequently than managerial staff (P < 0.001 and P < 0.001). Women belonging to the lowest income group had a lower score of kitchen equipment (P < 0.0001) and were less likely to enjoy cooking meal daily (OR = 0.68 (0.45;0.86)) than those with the highest income. CONCLUSION: Lowest socio-economic groups, particularly women, spend more time preparing food than high socioeconomic groups. However, female manual and office workers used less raw or fresh ingredients to prepare meals than managerial staff. In the unfavourable context in France with reduced time spent preparing meals over last decades, our findings showed socioeconomic disparities in food preparation behaviours in women, whereas few differences were observed in men

Premiers cris, premières nourritures

Cet ouvrage offre une mise en perspective des pratiques d’allaitement et de sevrage des nourrissons et des jeunes enfants, de la Préhistoire à nos jours. Plus qu’une histoire de l’allaitement, il dresse un bilan des savoirs les plus actuels autour de ces pratiques, depuis les premières minutes de vie jusqu’à l’abandon définitif du lait maternel. Un moment unique, un regard croisé sur les modes d’alimentation des tout-petits et leurs déterminants, cette thématique, qui implique tant les sciences humaines et sociales que les sciences médicales, est abordée dans une perspective diachronique, pluridisciplinaire et internationale. Les contributions réunies dans cet ouvrage vont au-delà des connaissances déjà produites par les historiens. S’appuyant sur d’autres sources documentaires, comme celles contenues dans les milliers de squelettes humains issus des fouilles archéologiques, et les techniques d’analyse du contenu chimique des ossements, il est désormais possible d’explorer le temps long, et de nuancer parfois les informations fournies par les textes anciens. Le large panorama ici retracé permet de conclure qu’au-delà des normes imposées par le discours médical ou militant, l’allaitement maternel n’a jamais été le mode d’alimentation exclusif des nourrissons. De tout temps et sous toutes les latitudes, les comportements d’allaitement ont été modelés par des facteurs physiologiques, psychologiques, familiaux, d’ordre social et économique au « sein » desquels les politiques de santé ont également tenté de s’imposer
