Comprehension and food analysis of a fermented mixture of animal proteins and vegetable proteins : influence on the physico-chemistry and the accepta…
2017
Many problems have been identified following the attempts to incorporate vegetal proteins in our food. In particular, off-flavor, taste or texture have been highlighted as real barriers to the acceptability of plant products by consumers. The consumer himself is also an important determinant regarding the term "acceptability." So, in order to develop a new fermented product based on pea, two issues were studied: the product and the consumer. To understand the physico-chemical properties and the acceptability of pea protein-based fermented products, several factors have been investigated in successive stages such as culture, positive health and environmental claims, lactic acid bacteria stra…
Developing sustainable food : the role of consumer liking in optimization of pea yogurt
2016
International audience; In the development of new food consumers’ acceptability is a critical factor. This study aimed at evaluating the possibility to introduce pea proteins as new fermented food. For this purpose, mixtures of cow and pea milks with different ratios of pea (0, 10, 20, 30, 40 and 100%) were fermented with French commercial yogurt-ferment. Consumer acceptability in two European countries: France (Western Europe) and Bulgaria (Southeastern Europe) was investigated. 60 Bulgarian and 70 French panelists were asked to rate: overall acceptability, appearance, odor, taste and texture on a hedonic scales going from 1 (I do not like at all) to 7 (I like very much). The ANOVA showed …

From sensory evaluation to food product development: how to fit a new vegetal fermented product to the consumer taste
2016
International audience; We present a series of studies showing the role of sensory evaluation in the optimization of new vegetal fermented products.The first series of studies showed that French consumers did not accept fermented products with vegetal protein ratio over 10%.Moreover, positive information on vegetal protein benefits did not lead to an increase in liking scores. So, a second series ofstudies was carried out in order to optimize the raw material and processes used to prepare the products and improve theirorganoleptic properties. In a first step, the vegetal proteins were purified permitting to obtain firmer products with less offflavors. In a second step, the effect of four fa…
