Stinging nettle (Urtica dioica L.) as a functional food additive in egg pasta: Enrichment and bioaccessibility of Lutein and β-carotene
2018
Abstract The use of stinging nettles as an ingredient in egg pasta has been evaluated with respect to food enrichment with carotenoids. Bioaccessibility of lutein and β-carotene has been estimated by dynamic simulation of the digestion process, with particular attention to duodenum and colon stages. Higher bioaccessibility for the two carotenoids occurs between 2 and 24 h of colonic fermentation and it is around 35% for lutein and 10% for β-carotene. However, the results reveal that the food matrix has a significant role in carotenoid release during the digestion process. In general, nettle enriched pasta has a lower carotenoid bioaccessibility than dietary supplement at duodenum and after …
Natural versus enriched food: Evidence from a laboratory experiment with chewing gum.
2019
Abstract The current study explored consumers' preferences for natural versus enriched foods and identified the underlying driving forces behind consumer interest towards both attributes. A laboratory experiment with 200 respondents was carried out, applying the incentive compatible Becker-DeGroot-Marschak mechanism to measure consumers' willingness to pay for natural and enriched attributes of chewing gum. Empirical findings reveal that the two attributes are evaluated similarly by consumers. Furthermore, structural equation modelling identified a strong interdependence between the natural and the enriched attributes, suggesting they are complementary rather than substitutes/alternatives i…
Sustainable Value Creation in the Food Chain: A Consumer Perspective
2020
The growth of diet-related diseases is becoming an important societal concern and a challenge for a more sustainable society. This has developed important trends in food consumption, including the increasing demand for food with a natural attribute and with health claims (e.g., enriched food). Consumers tend to evaluate these two attributes as superior ones and tend to pay a premium price for them. Accordingly, the value added by producers also will upturn if they take into consideration the consumers&rsquo
Sterol Digestion in Plant Sterol-Enriched Foods: Bioaccessibility and Fermentation
2021
Plant sterol-enriched foods have proved to lower serum total and low-density lipoproteins-cholesterol concentration, so they have faced a great increase in the market over the past 20 years through accepted health claims. This chapter provides an overall and critical picture on the current knowledge and future perspectives regarding bioaccessibility and fermentation of sterols contained in plant sterol-enriched food products, particularly focused on the effect of food matrix composition, as well as different in vitro gastrointestinal digestion methodologies, and the role of microbiota in the sterol degradation. The final objective of this chapter is to evince the different aspects of the di…
Current and new insights on phytosterol oxides in plant sterol-enriched food.
2011
Over the past 15 years, plant sterol-enriched foods have faced a great increase in the market, due to the asserted cholesterol-lowering effect of plant sterols. However, owing to their chemical structures, plant sterols can oxidize and produce a wide variety of oxidation products with controversial biological effects. Although oxyphytosterols can derive from dietary sources and endogenous formation, their single contribution should be better defined. The following review provides an overall and critical picture on the current knowledge and future perspectives of plant sterols-enriched food, particularly focused on occurrence of plant sterol oxidation products and their biological effects.
