The potential of pulsed electric fields to reduce pesticides and toxins
2020
Abstract Several studies have demonstrated the feasibility of pulsed electric fields (PEF) for different applications in the food industry. PEF technology is a valuable tool to improve functionality, extractability, and recovery of nutritionally valuable compounds as well as bioavailability of micronutrients and components in a diverse variety of foods. Moreover, some studies have shown the potential of PEF treatments to reduce the formation of food processing contaminants, pesticides, and toxins. This opens the doors to new PEF applications in the food industry. Recently, scientists explored the possibility of removing harmful chemical, such as pesticides and toxins, from food commodity by…
Reproducibility and relative validity of a newly developed web-based food-frequency questionnaire for assessment of preconception diet
2019
Abstract Background The importance of diet and nutrition during preconception age is a window of opportunity to promote future parental and transgenerational health. As a sub-study to a large Norwegian study, ‘Diet today – health of tomorrow’, a food-frequency questionnaire (FFQ) was developed to assess diet during the preconception phase in young adults aged 20 – 30 years and in this paper we report the reproducibility and relative validity of this questionnaire. Methods The FFQ was developed from an existing FFQ validated in adolescents. Participants were recruited on social media and at a university. Reproducibility was assessed by comparing the test and retest of the FFQ. Relative valid…
Impact of Oral Microbiota on Flavor Perception: From Food Processing to In-Mouth Metabolization.
2021
International audience; Flavor perception during food intake is one of the main drivers of food acceptability and consumption. Recent studies have pointed to the oral microbiota as an important factor modulating flavor perception. This review introduces general characteristics of the oral microbiota, factors potentially influencing its composition, as well as known relationships between oral microbiota and chemosensory perception. We also review diverse evidenced mechanisms enabling the modulation of chemosensory perception by the microbiota. They include modulation of the chemosensory receptors activation by microbial metabolites but also modification of receptors expression. Specific enzy…
Perspectives for biocatalysts in food packaging
2008
Since the market for minimally processed foods is broadening, packaging is being implemented in strategies that actively contribute to the food preservation and transformation concepts. One opportunity is given by the incorporation of biocatalysts, usually in prefabricated carriers, where they can fully retain their activity. These biocatalysts can be repeatedly reused within the packaging or, under controlled conditions, migrate to the product. The potential use of packages composed of classic polymers with functional surfaces or highly swellable biopolymers is being successfully tested, showing good perspectives for the controlled release when directly used in contact with the product or …

Cooked and raw. Fruits and seeds in the Iberian Palaeolithic
2022
Fruits, seeds, leaves and underground storage organs were all consumed by human groups during the Palaeolithic. These plant foodstuffs provided humans with minerals, vitamins and nutrients essential for optimal health. In this sense, fire control was a crucial human achievement since cooking allowed the physical and chemical modification of these elements by eliminating toxins, enhancing the digestion of foodstuffs and increasing their energy value. The use of fire during plant processing increases the potential preservation of archaeobotanical remains, as well. Based on the preserved plant elements and their characteristics, the chaîne opératoire of plant consumption can be reconstructed. …
Chapter 7. Food Processing
2019
International audience; Gases in Agro-food Processes is the ultimate reference covering all applications of gases in agro-Food processes, from farm to fork. Divided into 11 sections, the book covers chemical and physical gas properties, gas monitoring, regulation, heat and mass transfers. Sections are dedicated to agriculture and food processing, wastewater treatment, safety applications and market trends. Users will find this to be a valuable resource for industrial scientists and researchers in technical centers who are developing agro-food products. In addition, the book is ideal for graduate students in agro-food science, chemistry and the biosciences.
The Cereal Market and the Role of Fermentation in Cereal-Based Food Production in Africa
2014
Cereals represent the main crop in Africa (45% of arable land) and make an important contribution to the human diet in this continent. Cereals for humans are not consumed raw. Fermentation technology is widely used in Africa to transform cereals into edible products as well as to preserve and enhance the nutritional and safety aspects of cereals. In general, in Africa, this process is not controlled and is devoid of good manufacturing practices (GMPs). Spoilage and/or pathogenic microorganisms may compromise the final quality when the fermentation is not controlled. This article focuses on the role that the fermentation process could play in creating safe food conditions in Africa. Taking i…
Processing Strategies to Inactivate Hepatitis A Virus in Food Products: A Critical Review
2015
Hepatitis A infection, caused by hepatitis A virus (HAV), is the leading cause of human viral hepatitis throughout the world and is mainly propagated via the fecal–oral route. Transnational outbreaks of food-borne infections are reported with increasing frequency as a consequence of international food trade. Food-borne outbreaks caused by HAV are mainly associated with bivalve molluscs, produce (soft fruits and leafy greens), and ready-to-eat meals. The purpose of this paper was to conduct a structured and systematic review of the published literature on the current state of knowledge regarding the stability of HAV in foods as well as the efficacy of food processing strategies and to identi…
