QALIBRA-Heilsuvogin. Third Annual Report

This report is the third annual report of the European project QALIBRA and covers the period 1.04.2008 to 31.03.2009. QALIBRA, or “Quality of Life - Integarted Benefit and Risk Analysis. Webbased tool for assessing food safety and health benefits, ”abbreviated QALIBRA (Heilsuvogin in Icelandic), is the name of a European project, which falls under Priority 5, Food Quality & Safety in the 6th EU Research Program. This is a three-and-a-half-year project managed by the Fisheries Research Institute (now Matís ohf). The project manager is Helga Gunnlaugsdóttir, department manager at Matís. The aim of the QALIBRA project is to develop quantitative methods to assess both the positive and negative effects of food ingredients on human health. These methods will be presented in a computer program that will be open and accessible to all stakeholders on the World Wide Web. Participants in the project are from Iceland, the United Kingdom, the Netherlands, Greece, Portugal and Hungary.

“QALIBRA - Quality of life - integrated benefit and risk analysis. Web - based tool for assessing food safety and health benefits ”is a project funded by the EC's Sixth Framework Program, Priority 5, Food Quality & Safety. It started in April 2006 and will end in 2009. To assess the balance between the risks and benefits associated with a particular food, they must be converted into a common measure of net health impact. Uncertainties affecting the risks and benefits cause uncertainty about the magnitude and even the direction of the net health impact. QALIBRA will develop methods that can take into account multiple risks, benefits and uncertainties and implement them in webbased software for assessing and communicating net health impacts. The objectives of QALIBRA are to develop a suite of quantitative methods for assessing and integrating beneficial and adverse effects of foods, and make them available to all stakeholders as web-based software for assessing and communicating net health impacts. The participants in the project are: Matís, Iceland, coordinator, Central Science Laboratory, United Kingdom, National Institute of Public Health and The Environment, The Netherlands, Wageningen University, The Netherlands, University of Patras, Greece, Altagra Business Service, Hungary, National Institute for Agriculture and Fisheries Research, Portugal.

HEALTH DIET: A summary of the main categories of health foods and scientific evidence of their effectiveness

Foods that are considered to be able to improve human health can be classified as health foods such as unchanged organically grown foods, dietary supplements and target foods. In the first part of this dissertation, definitions and regulations are reviewed, the material and function of popular health products and permitted health claims are discussed. According to regulations, food supplements are foods that are intended as a supplement to a regular diet, but targeted foods are often defined as foods that have been modified in order to increase their health effects. The second part of the dissertation deals specifically with proteins in health products with an emphasis on the bioactivity of peptides. Bioactive peptides have a beneficial effect on health beyond normal nutritional value. They can have physiological effects on the activity of the gastrointestinal tract, cardiovascular system, immune system and nervous system. The effects of peptides in these systems are reviewed. The potential of fish muscle protein in the healthcare product market is being considered. Nowadays, a very large amount of underutilized by-products from seafood, and research has therefore focused a lot on finding ways to utilize and increase their value. The target food market is booming at the moment and is forecast to expand. Seafood has a positive health image among consumers and therefore health products that contain fish muscle protein could have an impact. However, it requires the right taste, texture and bioactivity to be delivered to the consumer, in addition to which the products need to be introduced to the products in a targeted and powerful way.

Food that has the potential of improving health can be categorized as health food eg organic food, dietary supplements and functional food. Definitions, regulations, composition and functionality of popular health food and permitted health statements, are discussed. According to regulation dietary supplements are foods that are intended as an addition to a normal diet, however functional food is commonly referred to as food that has been fortified to enhance its positive effects on health. The latter part of this paper discusses proteins in health foods with emphasis on bioactive peptides. Bioactive peptides have a positive effect beyond their regular nutritional value. They have been shown to have a biological effect in the alimentary canal, the heart and the vascular system, the immune system and the nervous system. The mechanisms involved are reviewed. The potential of fish protein in the functional food market will also be addressed. Today, great quantity of marine by-products are underutilized. Therefore, emphasis has been within the research community on finding methods to utilize and enhance their value. Currently the functional food market is blooming and is expected to grow in the following years. Marine products have a positive health image among consumers, thus health products containing fish proteins could be a great success. To be realized, this requires that the right taste, texture and bioactivity is delivered to the consumer accompanied by a good advertisement campaign.

Blue whiting as a target food

The aim of the project was to answer the research question: What bioactivity can be obtained from peptides extracted from blue whiting with enzymes? Bioactivity is a prerequisite for the use of blue whiting as a target food. Isolated blue whiting proteins were used as raw materials. The study showed that degraded blue whiting proteins have bioactivity. However, the sensory properties of products did not prove to be good enough and yields were low. This was especially so due to the difficulty of obtaining fresh blue whiting as a raw material. In the second steps of the project, it was decided to use cod. The aim was to investigate in particular whether isolated cod proteins had other properties than hacking in terms of sensory evaluation and antihypertensive properties of products. The result was that no differences in these characteristics were found in the study. The project investigated the interaction of hydrolysis with enzymes and processing properties and bioactivity. The interaction of hydrolyzed blue whiting proteins isolated by a new method and their bioactivity has not been performed before and was an international novelty. The project acquired extensive knowledge in the field of enzyme degradation and the bioactivity properties of protein products.

The aim of the project was to answer the question: What kind of bioactive properties do peptides produced by enzyme hydrolysis of blue whiting have? Some sort of bioactivity is needed if they are to be used in functional food. The substrate for the hydrolysis was isolated blue whiting proteins. Well-known, commercially available enzymes were used to hydrolyze the proteins to different degrees of hydrolysis (%DH). The blue whiting hydrolysates showed bioactive properties, but their sensory characteristics were not good. Furthermore, the yield of the process was low. The reason for this was a shortage of fresh raw material. Thus, in the next steps cod was therefore used. The main aim was to study whether different sensory and bioactive characters were achieved when isolated proteins were used compared to mince. The results of the project indicate that there is no difference. In the project the connection between enzyme hydrolysis and functional and bioactive properties was examined. Main emphasis was on the effect of using isolated proteins as raw material for enzyme hydrolysis. In the project important knowledge in the field of enzyme hydrolysis and bioactivity was gained that will facilitate future research.
