Incorporating sardine cooking water aromas into plant-based diets for european ...

Sardine cooking wastewaters are by-products of the canning industry with great potential for valorisation. We have hypothesized that they can be a source of aromas to enhance appetite when added to plant-based diets. The poor palatability of such diets often described in carnivorous species poses a recurring problem in fish farming, with harsh consequences on fish growth performance and flesh quality. Aromas fr...

Repurposing sardine cooking wastewaters as ingredients for European seabass diets

Dietary inclusion of sardine cooking waters: impact on appetite regulation, gro...

Introduction Plant-based ingredients have been considered suitable options for replacing marinebased ones in aquafeeds (Naylor et al., 2021), but this may compromise diet palatability (Geurden et al., 2013), potentially affecting fish growth and flesh quality. To overcome this, feed attractants have been suggested. These compounds, like alcohols, aldehydes, and organic acids, were reported to stimulate intake i...

Can sardine cooking wastewaters modulate European seabass feed intake?

The goal of this work was to evaluate three extracts from sardine cooking waters, a by-product of the canning industry, as feed intake modulators, when included in highly vegetable diets, which often display low intake by carnivorous species. Sardine cooking waters, supplemented with acorn extract (Aroma 3) were processed, by vacuum condensation (Aroma 1) or liquid/liquid extraction with soybean oil (Aroma 2). ...

Comparative analysis between synthetic vitamin E and natural antioxidant source...

Synthetic vitamin E is commonly used in aquafeeds to prevent oxidative stress in fish and delay feed and flesh oxidation during storage, but consumers’ preferences tend towards natural antioxidant sources. The potential of vegetable antioxidants-rich coproducts, dried tomato (TO), carrot (CA) and coriander (CO) was compared to that of synthetic vitamin E included in diets at either a regular (CTRL; 100 mg kg−1)...

Evaluation of sardine cooking wastewaters as feed intake modulators for Europea...

There has been a tendency to replace marine ingredients in aquafeeds, namely fishmeal, with more sustainable vegetable protein sources. However, this replacement often reduces diet palatability, with a subsequent decrease in feed intake and growth and/or alteration of flesh quality. The goal of this work was to evaluate the effectiveness of aromatic mixtures extracted from sardine cooking wastewaters, a by-prod...

Application of eye-tracking technology for the evaluation of different packagin...

The main goal of this study was to assess the impact four graphic designs (figure 1) on the perception of different extrinsic characteristics (premium and organic denomination, infusion name and brand).

Acceptance of fish and fish products by Portuguese young consumers: an explorat...

Portugal is one of the major fish consuming countries in the World, from where one may collect experiences in order to improve fish consumption in other countries. The aim of this research is to explore the factors that influence the consumption of fish and seafood among 8-14 year old children from the Oporto metropolitan area. A focus group was conducted with mothers of children to gain insights into their kno...
