Sunflower Bark Extract as a Biostimulant Suppresses Reactive Oxygen Species in Salt-Stressed Arabidopsis Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
A survey of plant-based wastes identified sunflower (Helianthus annuus) bark extract (SBE), produced via twin-screw extrusion, as a potential biostimulant. The addition of SBE to Arabidopsis (Arabidopsis thaliana) seedlings cultured in vitro showed a dose-dependent response, with high concentrations causing severe growth inhibition. However, when priming seeds with SBE, a small but significant increase in leaf area was observed at a dose of 0.5 ...
Belgian endive-derived biostimulants promote shoot and root growth in vitro Instituut voor Landbouw-, Visserij- en Voedingsonderzoek Universiteit Gent
Recovering biostimulant compounds from by-products of crops is a promising strategy to add value, enhance sustainability, and increase the environmental safety of the agricultural production chain. Here, we report consistent root and shoot growth-stimulating bioactivity present in water-based extracts from Belgian endive forced roots (Cichorium intybus var. foliosum) over two consecutive harvest years. The shoot and the primary root of in vitro ...
Incorporation of leek powder (Allium ampeloprasum var. porrum) in wheat bread: Technological implications, shelf life and sensory evaluation Instituut voor Landbouw-, Visserij- en Voedingsonderzoek Universiteit Gent
In this study, the incorporation of leek in wheat bread was explored. Green leek leaves were dried with two techniques to obtain leek powder after milling. The air-dried and freeze-dried powders were incorporated into wheat flour at five substitution levels (0, 0.5, 1, 1.5 and 2 g/100 g). The impact of leek powder on dough rheology, bread quality, sensory evaluation and mould-free shelf-life was investigated. Leek powder negatively impacted the ...
Influence of cultivar and growing location on composition and functionality of dietary fibre concentrates produced from forced roots of Belgian endive (Cichorium intybus var. foliosum) Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
Forced roots of Belgian endive (Cichorium intybus var. foliosum) are by-products with promising valorization
potential. The roots of four cultivars grown in four locations and mixes derived thereof, were used to produce
dietary fibre concentrates (DFCs). Obtained DFCs were characterized by a low concentration of total sugars (TS),
phenolic compounds (PCs) and sesquiterpene lactones (SLs) and high content of the dietary fibre (DF) ...

Toroidal cans for thermal processing of liquid and solid-liquid mixtures under static and end-over-end rotation Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
Heat transfer is mainly influenced by can geometry and product type. Agitating retorts have been widely used for heat transfer for liquid foods. Since convective heat transfer coefficient is high, this leaves the container geometry the only option to increase heat transfer rate and decrease process time for quality improvement. This is even valid for agitation processes due to applied limitation in the rotation rates. A recent innovation for ...
Opportunities within the agri-food system to encourage a nutritionally balanced diet– Part II Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
The field-to-fork concept comprises opportunities for providing consumers with nutritious and health-beneficial food in order to meet the growing interest in health-beneficial foods and to counteract the increase of diet-related diseases worldwide. While raw plant-/animal-based starting material is considered as the primary source of such compounds (see Part I), waste fractions from this primary biomass are additional sources. Opportunities ...
Opportunities within the agri-food system to encourage a nutritionally balanced diet– Part I Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
To meet their growing interest and to counteract the increase of diet-related diseases worldwide, the field-to-fork concept comprises opportunities for providing consumers with nutritious and health-beneficial food. Although health-beneficial effects have been ascribed to specific food compounds, most often in vivo human evidence and/or accepted health/nutrient claims are lacking. Part I of this review gives an overview of possible sources of ...
Upcycling of Belgian endive (Cichorium intybus var. foliosum) by-products. Chemical composition and functional properties of dietary fibre root powders Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
By-products of Belgian endive represent an interesting yet underutilised source of dietary fibre (DF). Dietary fibre concentrates (DFC) that are low in sugar and neutral in taste are sought by the food industry to increase DF content and improve texture in food products. The aim was to set up a biorefinery process to produce DFC from forced roots of Belgian endive (DFC-BE) and characterise the resulting product. As a control, non-treated forced ...
Innovative refractance window drying technology to keep nutrient value during processing Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
The evaluation of the impact of food processing on the nutrients and health benefits of vegetables and fruits is of high practical importance. In this short literature overview the refractance window drying (RWD) technology, a novel contact drying technique, was compared with other drying techniques as the freeze drying technique to stabilize fruits and vegetables. The antioxidant capacity, phenolic or polyphenol content and carotenoids are ...
