Can seaweed have a positive effect on blood sugar? Do you want to participate to increase knowledge?

The Laboratory of Geriatrics, Landakot 5L and the Faculty of Food and Nutrition at the University of Iceland are requesting participants in a study that has been approved by the Science Ethics Committee.

  • Participants need to be healthy, adults, 40 years and older. Participants with a body mass index of 30 kg / m2 or higher can participate (see table with calculated body mass index below). Participants who exercise regularly are excluded from participation as well as pregnant women or women who are breastfeeding.
  • Objectives The study is investigating the effect of different doses of bladderwort extract on short-term blood glucose in healthy adults.
  • Participation in the study involves attending three times for two and a half hours blood glucose tests and body measurements. Participants will receive different doses of bladderwort extract along with 50 g of carbohydrates at each arrival. Measurements of body composition, height and weight will be performed. In addition, participants will be asked to provide information on general health.
  • Balloon seaweed (Fucus vesiculosus) is rich in iodine, indigestible starch, salt and bioactive substances. Bladderwort extraction occurs when certain bioactive substances are extracted from the bladderwort and isolated. These bioactive substances are placed in gelatin capsules for easy ingestion. The use of kelp for human consumption is known and research on bioactive substances in kelp both here in Iceland and abroad suggests that kelp extract can have a positive effect on blood sugar control as kelp extract reduces the absorption of carbohydrates in the gastrointestinal tract.
  • Participation is not paid for.

Interested parties who meet the above criteria are asked to have

Analysis of spoilage processes during fresh fish transport / Comparison of transport and packaging methods for fresh fish products – storage life study

The aim of the project "Best fresh fish transport" was to improve the handling of fresh fish products in container transport and thereby increase their shelf life and the possibility of further transport by sea from Iceland, but there are significant savings compared to transport by air. This report deals with the analysis of the damage processes that take place during the storage and transport of fresh fish products. A comparison was made of transport in foam plastic boxes and in ice scrapers in pots at different temperatures. Different embodiments of both packaging solutions were compared and assessment factors included temperature, total number of microorganisms, amount of damaged microorganisms, water resistance, amount of erratic base and sensory assessment properties. In general, there was relatively little difference between experimental groups during storage. Differences were found between groups in individual sensory evaluation factors, but this difference was not comparable between days and is therefore probably due to the interaction between heterogeneous raw material and too few evaluated samples. The freshness time of all groups was seven to eight days and the shelf life was about 10 days. The packaging solutions studied in the experiment, as well as the storage temperature, had little effect on the spoilage processes of the cod products. The variability was primarily due to the storage time.

The aim of the project "Optimisation of fresh fish transport" was to improve the handling of fresh fish products during sea freight and increase the shelf life and the possibility of further maritime transport from Iceland, involving significant savings relative to the air freight. The present report covers analysis of the deterioration processes occurring during storage and transportation of fresh whitefish products. Comparison was made between transportation in expanded polystyrene boxes and in slurry ice in tubs at different ambient temperatures. Different versions of both packaging solutions were compared with regard to temperature, total viable count, amount of spoilage bacteria, water holding capacity, total volatile nitrogen bases (TVB‐N) and sensory properties. There were in general relatively small differences between experimental groups during the storage period. Some difference was observed between groups with regard to few sensory attributes, but the difference was not comparable between days which was likely due to heterogeneous material and too small sampling size. The freshness period of all experimental groups was seven to eight days and the shelf life around 10 days. The packaging solutions explored in the present study, as well as storage temperature, had generally little effect on the deterioration processes occurring in the fresh cod product. The observed variation was primarily attributed to the storage time.

Economic analysis of fresh fish transportation

The aim of the project Optimization of fresh fish transport is to improve the handling of fresh fish products in container transport and thereby increase their shelf life and the possibility of further transport by sea from Iceland. In work component 4, the development of fresh fish transport from Iceland is analyzed according to the mode of transport and the main market areas for fresh fillets and pieces. An economic analysis of the use of pots and foam boxes is carried out with regard to packaging and transport costs. Exports of fresh whitefish fillets and pieces have increased rapidly over the past decade. Year after year, the amount of fresh fillets and chunks imported from Iceland by sea increases. A product that was almost exclusively transported by air a decade ago is now almost equally transported by ship. The results show that the amount of fresh fillets and pieces transported by ship from Iceland almost increased sixfold from 2004 to 2014. In 2013 and 2014, about 90% of the fresh fillets and pieces transported by ship were transported to two markets; Britain and France. The results of a cost analysis show that it is considerably cheaper to pack a product in a pot than a foam box. Transport costs are also lower in most cases when comparing pots with foam boxes. It is more than half as low when comparing the cost of transporting a container of pots on the one hand and 3 kg of foam boxes on the other. However, there are some limiting factors in the use of pots. All things being equal, pots are not likely to replace a foam box except in part due to practical aspects of product distribution. In some cases, however, transport in pots could be very suitable.

The aim of the project Optimization of fresh fish transport is to improve handling of sea transported fresh fish products, thereby improving their quality and increasing the possibility of sea transport from Iceland. The aim of work package no. 4 is to analyze main markets and the development of fresh fish transport from Iceland. Also compare cost of traditional packaging in expanded polystyrene (EPS) boxes to pack the product in tubs containing slurry ice. Export of fresh white fish fillets and loins from Iceland has increased rapidly over the last decade. More and more fillets and loins are transported with ships. What used to be an exclusive air freight business is now almost equal (air vs. sea). The results show that the volume of fillets and loins transported with ships from Iceland nearly six folded from 2004 to 2014. In 2013 and 2014 almost 90% of the export went to two markets; Britain and France. Results show that cost of packing product in tubs is significantly lower than using EPS boxes. Transportation cost was also lower in most cases when using tubs than EPS, as much as half of the cost when compared to the smallest EPS box (3 kg) in a full container. Some factors limit the practicality of using tubs rather than EPS. It is unlikely that tubs will replace boxes unless introducing matching distribution options. In some cases using tubs can be both practical and very cost efficient.

The first workshop in MacroFuels

MacroFuels is a project that is part of Horizon 2020, the European Research Program 2014-2020, and the project began at the beginning of the year. Matís participates in this project, which aims to develop fuels from seaweed, for example butanol, ethanol, furanic substances and biogas (methane).

The project covers all aspects of the production chain: Algae cultivation of different species, harvesting technology, pre-processing as well as the development of chemical and biological transformations of seaweed sugars into fuel molecules.

MacroFuelsIceland_GroupPic

Participants are universities, research institutes and companies from Iceland, Denmark, the Netherlands, Scotland, Belgium and Germany. Matís will develop and study enzymes and microorganisms to break down this biomass and use it to make fuel.

The first workshop lasted two days, reviewing the first six months of the project, what had been done and what had been achieved. One day was so well used in the organization of work in the project's work packages.

After the meetings, the participants went together to Reykjadalur, and got to know Icelandic nature and bathed in hot pools.

By-products from whitefish processing / By-products from catfish processing

This report summarizes information on the utilization of important catfish species in Iceland, explains which products are processed from the resulting raw material and examines the possibilities for increased utilization of by-product raw materials. The report is prepared in connection with the Nordic research project "Alt i land" led by the Faroese company Syntesa. "Alt i land" is part of the Faroese Presidency's program of the Nordic Council of Ministers, which examines the current utilization and possibilities for improving utilization in catfish processing in the Faroe Islands, Greenland, Norway and Iceland. The main results from this project show that utilization in catfish processing in Iceland is significantly higher than in the other countries. In addition to publishing this report, Matís has held two workshops in connection with the project, where stakeholders came together to discuss possible opportunities to increase utilization and value creation in catfish processing.

The objective of this report is to analyze the current utilization of the most important Icelandic whitefish species and identify possibilities for improving utilization of by-raw materials even further. The report is a part of a larger international project, called “Alt i land”, which is led by the Faroese company Syntesa. Alt i land is a part of the Faroese chairmanship program at the Nordic Ministers of council. The objective of Alt i land is to study and compare utilization in whitefish processing in Faroe Islands, Greenland, Norway and Iceland, and to suggest how utilization can be improved in these countries. The main results from that project show that utilization is much higher in Iceland than in the other countries. In addition to publishing this report, Matís has facilitated a series of workshops with selected stakeholders where potentials in increasing utilization have been discussed.

Comparison of packing of fresh fish products in boxes and pots for export by ship / Packing of fresh fish products in boxes and tubs intended for sea transport

The aim of the study was to find the best and most cost-effective method of packing fresh fish products for shipping with a view to maximizing the shelf life of a product, which is one of the key factors in the marketing of fresh fish products. Experiments were carried out with the transport of fresh fish products in containers with ice scrapers and compared with the transport in foam plastic boxes with regard to temperature control, product quality and transport costs. Different product groups were compared that were packed in different packaging and stored at different storage temperatures. The purpose of these experiments was to simulate the environmental conditions during the transport of fresh fish products, with a view to evaluating the effect of pre-cooling before packaging and packaging methods on the shelf life of the products. The results clearly indicate that refrigeration of products before packaging as well as low and stable storage temperatures are among the most important factors that increase the shelf life of fresh fish products. Different packaging solutions also affected the shelf life of fresh fish products, although the effect was not as decisive as the effect of temperature. The results indicate an increased likelihood of longer shelf life if fresh fish products are packed in tanks with sub-chilled sludge compared to traditional packaging in a foam plastic box with ice. To estimate the amount of ice scraper required to maintain an acceptable temperature, a heat transfer model was developed. An economic analysis of different packaging and transport was carried out in the project and this work shows significant savings with the use of tanks for transporting fresh fish products in comparison with foam plastic boxes. Pots can replace a foam plastic box to a considerable extent and be a cost-effective option for some companies. The economic analysis showed that larger parties could take advantage of this method, as they can fill entire containers for export. But the method is no less useful for smaller processes, which do not have the capacity to make large investments in equipment to ensure adequate cooling for the packaging of products for export of fresh raw materials. The results are a good contribution to discussions about fresh fish products in foreign markets.

The goal of the study was to find the best and most efficient method of packaging fresh fish for sea transport with the aim of maximizing the storage life of the product, which is a key element in the marketing of fresh fish. Experiments were made with the transport of fresh fish in tubs with slurry ice and compared with transport in expanded polystyrene boxes with regard to temperature control, product quality and shipping cost. Different product groups were compared, using different temperature conditions and packing methods to find the best outcome for fresh fish quality and storage life. Experimental results clearly indicate that the pre ‐ cooling for packaging and low and stable storage temperature play a major factor to maximize storage life of fresh fish products. Different packaging solutions are also a factor, though the effect was not as dramatic as the effects of temperature. The results indicate an increased likelihood of extended shelf life if fresh fish is packed in a tub with a slurry ice compared to traditional packaging in expanded polystyrene boxes with ice. In order to estimate the necessary amount of slurry ice to maintain acceptable temperature, a thermal model was developed. Economic analysis of different packaging and transport was also carried out and the results showed substantial savings with the use of tubs for the transport of fresh fish products in comparison with the styrofoam boxes.

Increased value of prepared dishes that have been enriched with ingredients from the sea

Some time ago, EnRichMar completed the project led by Matís. The project aimed to enrich food with hygiene from the sea, but the project was part of the 7th European Research Program for Small and Medium-sized Enterprises (FP7 SME).

The aim of the project was to increase the value of prepared foods by enriching them with raw materials and ingredients from unused seafood and by-products from fish processing. Emphasis was placed on omega-3 fatty acids and algae extracts, which can have an increased and positive effect on the health and stability of the food and increase its taste quality.

results

The project has created new business opportunities within and outside the group that participated in EnRichMar. The participating companies that produce bioactive substances have moved one step further and have marketed bioactive substances for a variety of foods in new lucrative markets. The diversity of bioactive ingredients has also increased due to the planned marketing of new ready-made dishes developed in connection with the project. The participating companies have acquired valuable market information on target foods, consumers' views on target foods in important markets and developed enriched foods based on information obtained from the main target groups. In addition, participants have first-hand information on the physiological effects of consuming enriched foods. It was fundamental for each participating company to develop a new and more valuable business model that will have a positive effect on their results in the future.

Increasing the value of raw materials and products will lead to increased diversity in healthy prepared dishes and can thus contribute to improved public health. The results are also important for the European fisheries sector and the utilization of marine resources due to the increased value of tributaries from the fisheries sector and underutilized marine resources.

It should be noted that the beginning of this project can be traced to a grant from Increased value of the Seafood Fund (AVS). As a result, the Nordic countries became interested in the project and a similar project was funded Norden, Nordic Innovation, Nordic Innovation Fund. Eventually, the project expanded even further, adding another group of participants, resulting in the EnRichMar project discussed in this article.

Two Icelandic participants were in the project in addition to Matís. Marinox and Grímur kokkur were involved from the beginning and it is safe to say that the benefits were significant for these Icelandic participants:

Grímur kokkur, Grímur Gíslason:

"It has been very important for our company to be part of EnRichMar and the cooperation was very good. EnRichMar has opened up export opportunities, helped us make healthy food healthier, and solved problems related to the production of meals containing omega fatty acids. We will market two products developed in the project this summer"

Marinox, Rósa Jónsdóttir:

"The EnRichMar project is a key factor in enabling Marinox to scale up the production of bioactive seaweed concentrate, and we have also received important information on the composition, efficacy and clinical benefits of the seaweed concentrate. Furthermore, the participation has supported Marinox in business development as it has opened up new market opportunities, given us important insights into the market for food raw materials and additives and also strong connections with new partners in research and business ".

A list of all participants and their reviews can be found on the leaflet Increased value of convenience foods by enrichment with marine based raw materials.
