Bread aroma

2020

: This chapter will review the different synthetic pathways of bread volatiles in conventional white bread. The influence of traditional and innovative raw materials and breadmaking processes on the formation of volatiles will then be discussed. Next, extraction and analytical methods used to identify volatiles that participate in bread aroma will be presented. Volatiles that have been identified in freshly baked white bread will be listed and the ones that are potent odorants highlighted. Finally, the techniques employed by the baking industry to enhance bread aroma will be described.

Relevance and feasibility of a personalized dietary intervention in older people with meals-on-wheels: a randomised controlled pilot trial

2020

International audience; Objective: The present study aimed at assessing the feasibility and the effectiveness of a personalized dietary intervention in a meals-on-wheels service through a randomized controlled pilot trial. Design: Sixty recipients of home-delivered meals (75% of women; 70-97 years old) were recruited and randomly assigned to a control and an experimental group and followed over a period of 4 months. In the experimental group, the nutritional status (Mini-Nutritional Assessment ? MNA questionnaire), the food intake and the food preferences were measured for each participant. Based on this screening, participants were provided with dietary guidance and follow-up. Those at ris…

Does toddlers' food intake differ according to variations in fat, salt or sugar in foods?

2009

National audience; In many developed countries, governmental policies encourage reduction of fat, salt and sugar consumption. However, such reductions are likely to impact the palatability of foods, in particular in children, whose food intake is largely influenced by food's sensory features. The extent to which young children's food intake varies according to fat, salt and sugar content is imperfectly known. This study aimed to evaluate whether toddler's food intake varied from one meal to the other (1) during lunches where salt or fat contents were modified in some foods and (2) during snacks where sugar or fat contents were modified. Sixty-four children (24–36 months old) participated in…

The first COVID-19 lockdown reveals an ambivalent relation of French parents with food pleasure: the struggle to find a balance

2021

International audience; In France, a first COVID-19 lockdown took place from March-May 2020. Using an online survey including three open-ended questions, this study explored parents' experiences regarding changes in their family's eating behaviors during this lockdown. French parents (n = 498, 71% mothers) of young children were invited to describe which food-related changes they (1) perceived as positive during the lockdown, (2) perceived as negative, and (3) would like to maintain after the lockdown. A thematic analysis revealed that parents appreciated the choice of more local, fresh and high-quality foods, the time to prepare foods (homemade dishes, new recipes) and cooking and eating w…

Accentuating the Interrelation between Consumer Intention and Healthy Packaged Food Selection during COVID-19: A Case Study of Pakistan

2021

This study contemplates the factors that influence consumer intention, before and during the eruption of COVID-19, for the selection of healthy packaged food in Pakistan. The extant studies have identified two distinct attitudes of consumers about food label information: one is its usefulness and the second elucidates the avoidance. Hence forth, the current study contributes to the extant literature while signifying both reasons which motivate consumers to read food labels and reasons which discourage consumers from consult food labels at the point of purchase. Moreover, the impact of subjective norms and self-efficacy for healthy packaged food intentions has also been examined for both bef…

Glycerosomes: Use of hydrogenated soy phosphatidylcholine mixture and its effect on vesicle features and diclofenac skin penetration.

2016

In this work, diclofenac was encapsulated, as sodium salt, in glycerosomes containing 10, 20 or 30% of glycerol in the water phase with the aim to ameliorate its topical efficacy. Taking into account previous findings, glycerosome formulation was modified, in terms of economic suitability, using a cheap and commercially available mixture of hydrogenated soy phosphatidylcholine (P90H). P90H glycerosomes were spherical and multilamellar; photon correlation spectroscopy showed that obtained vesicles were ∼131nm, slightly larger and more polydispersed than those made with dipalmitoylphosphatidylcholine (DPPC) but, surprisingly, they were able to ameliorate the local delivery of diclofenac, whic…

COMBINATION OF ARGAN OIL AND PHOSPHOLIPIDS FOR THE DEVELOPMENT OF AN EFFECTIVE LIPOSOME-LIKE FORMULATION ABLE TO IMPROVE SKIN HYDRATION AND ALLANTOIN…

2016

Allantoin is traditionally employed in the treatment of skin ulcers and hypertrophic scars. In the present work, to improve its local deposition in the skin and deeper tissues, allantoin was incorporated in conventional liposomes and in new argan oil enriched liposomes. In both cases, obtained vesicles were unilamellar, as confirmed by cryo-TEM observation, but the addition of argan oil allowed a slight increase of the mean diameter (∼130nm versus ∼85nm). The formulations, especially those containing argan oil, favoured the allantoin accumulation in the skin, in particular in the dermis (∼8.7μg/cm(2)), and its permeation through the skin (∼33μg/cm(2)). The performances of vesicles as skin d…

Nanodesign of new self-assembling core-shell gellan-transfersomes loading baicalin and in vivo evaluation of repair response in skin

2017

Gellan nanohydrogel and phospholipid vesicles were combined to incorporate baicalin in new self-assembling core-shell gellan-transfersomes obtained by an easy, scalable method. The vesicles were small in size (~107 nm) and monodispersed (P.I. ≤ 0.24), forming a viscous system (~24 mPa/s) as compared to transfersomes (~1.6 mPa/s), as confirmed by rheological studies. Gellan was anchored to the bilayer domains through cholesterol, and the polymer chains were distributed onto the outer surface of the bilayer, thus forming a core-shell structure, as suggested by SAXS analyses. The optimal carrier ability of core-shell gellan-transfersomes was established by the high deposition of baicalin in th…

Estimation of the committed radiation dose resulting from gamma radionuclides ingested with food

2014

The objective of the study was to estimate the value of the radiation dose absorbed in consequence of consumption of popular food products for individual age groups. Potatoes, corn and sugar beet were selected for the study. Edible parts of these plants were collected in experimental fields of the KWS Lochow Polska Sp. z o.o. seeding company in Kondratowice (Poland). On the basis of the obtained study results, it can be stated that in consequence of consumption of the selected food products, people may receive increased doses from both natural and artificial radioactive isotopes. The doses calculated for several age groups do not show any health hazards in consequence of consumption of the …
