TOPCOD, OPTILAR / Long live the first model. Preferred breeding processes in larval and juvenile farming of cod

Recent research has shown that the best conditions for the production of larvae produce juveniles of better quality and that the growth advantage in the early stages of rearing pays off to some extent in the later stages of growth. The main goal of this project is to define the best conditions for cod cod farming in Iceland and to that end use various methods to solve the main problems associated with the production of cod larvae today. This report discusses the work components that Matís ohf. participated in, among other things, researching the effects of enrichment of feed animals with supplementary bacteria and protein digestion on the growth, development, immune stimulation and digestive flora of larvae, as well as research on the effects of different primary feeds on muscle growth carried out in collaboration with the MRI. The results indicate that the start of dry feed feeding late or around 50 dph does not give the larvae a growth advantage and that it is sufficient to feed Artemia up to 40 dph. Dry feed from 30 dph led to lower growth and an increased incidence of structural defects. Enrichment of feed animals with a lyophilized mixture of two complementary bacterial strains did not affect the composition of bacterial flora larvae and strains did not gain a foothold in treated larvae. However, poor roe quality can be expected to have affected treatment outcomes. The results of experiments confirm previous results on the positive effect of enrichment of feed animals with protein digestion on the performance and development of larvae.  

Recent research has demonstrated that production optimization during the larval and juvenile phase will to some extent be reflected in the performance of the fish during the ongrowing phase. The objectives of the project are to optimize the larval production of Atlantic cod in Iceland by applying a multidisciplinary approach to solve central bottlenecks related to larval production. This report presents tasks where Matis ohf. was involved, including analyzes of the effects of live prey enrichment using putative probionts and a fish protein hydrolyzate on larval survival quality immune stimulation and intestinal bacterial community of larvae. The study also involved an analysis of the effect of startfeeding protocols on muscle growth in collaboration with MRI. The results indicate that late weaning around 50 dph may be excessive and produce no significant advantage. An intermediate weaning strategy, with brine shrimp feeding up to 40 dph, appears to be sufficient to convey important advantages in terms of growth and anatomy. Early weaning at 30 dph produced slow ‐ growing juveniles and a higher deformity ratio. Using the freeze dried preparations of the probionts did not affect the bacterial community structure of larvae and the probionts were not found to be established within the bacterial community of treated larvae. Poor quality egg may, however, partly explain the lack of effects as a result of treatment. The present study confirms the results of previous studies where live prey enrichment using a fish peptide hydrolyzate significantly improved larval survival and development.

Icelandic baby food - market and public requirements

Baby food refers to food that is specifically intended for infants and young children, with the exception of milk mixtures that are to replace breast milk. There are many things to consider before starting the production of baby food. Toddlers and infants are much more vulnerable in every way than adults. High demands are therefore made on safe production. Icelandic raw materials, especially vegetables and lamb, are well suited for the production of baby food because here the use of pesticides in agriculture is less than in most places and contaminants and pollutants are kept to a minimum. The results of discussion groups for parents of young children and toddlers indicate that there are opportunities to bring new, Icelandic products to market. In particular, there seems to be a lack of more types of baby food than are already available, but there are also opportunities to adapt the packaging and portion sizes of traditional Icelandic food to the needs of young children and toddlers. Purchased baby food has a negative connotation in the minds of many. In order for a new product intended for young and young children to be successful, it is first and foremost important to build trust in the brand among the buyers.

Baby food is food which is specially aimed towards infants and toddlers, excluding infant formulas which are replacement for breast milk. Many things have to be considered before starting producing baby food. Infants and toddlers are much more susceptive than grown-ups. High demands are therefore on safety of the production. Icelandic raw material, especially vegetables and lamb meat, are well suited for baby food as in Iceland the use of pesticides in agriculture is much lower than in most countries and pollution levels are low. Results from focus group discussions among Icelandic parents indicate that there are opportunities for new, Icelandic products on the market. There is especially a need for more variety but there is as well a market for existing Icelandic products in more suitable form and packaging for infants and toddlers. Processed baby food has negative image in the eyes of many parents. For new baby food products to succeed it is essential to build up a trust among parents on the integrity of the producer and quality of the products.

Meeting in the EU's new multinational project - Matís leads the collaboration

Matís plays a leading role in a new and extensive multinational project that the European Union has decided to support for three years, AMYLOMICS. The first meeting of the project was held on Monday 28 March at Matís' headquarters in Reykjavík.

The amount of the grant is a total of ISK 390 million, of which ISK 72 million will go to Matís and a total of ISK 58 million to two other Icelandic companies. In addition, master's and doctoral students will work on projects related to Amylomics.  

The AMYLOMICS project will utilize the diverse ecosystems of geothermal areas in Iceland to develop heat-resistant enzymes for use in the starch and sugar industries. Heat and acid resistance are essential properties in such industrial processes, but can be found in the enzymes of organisms in thermal areas.

Among the participants in AMYLOMICS is a French company Rocket Frères, which is one of the largest in Europe in the production of starch and derivatives, with an annual turnover of about 7 billion euros. Roquette Frères will be able to use enzymes that will be developed in the project to improve processes and innovate in its production. Some of the enzymes will be marketed by the start-up company Prokazyme for use in a variety of sugar industries.

  • Dr. Guðmundur Óli Hreggviðsson, subject manager at Matís, will be project manager. Two other Icelandic companies, directly involved in the project, Roche Nimblegen and Prokazyme.

The project and the EU's support for it are good news for the Icelandic scientific community and recognition for Matís. EU research grants are highly sought after and highly competitive. With this, Matís becomes even more established in international scientific co-operation, and of course it is a special gift for Icelanders to now receive substantial funds into society from abroad during these times of recession and austerity.

Matís' perfect facility for sensory evaluation research

Sensory evaluation is a systematic evaluation of the smell, taste, appearance and texture of food. In sensory evaluation, the human senses, i.e. visual, olfactory, taste, hearing and touch senses used to assess food quality.

Sensory evaluation in the Icelandic food industry has been conducted in an organized manner; especially as a factor in quality control. The fishing industry, meat processing and the dairy industry have made the most of these methods. Sensory evaluation in the Icelandic fishing industry has a rich tradition. Previously, all fish was evaluated for freshness and priced accordingly.

The fishing industry, meat processing and the dairy industry have made the most of these methods. Sensory evaluation in the Icelandic fishing industry has a rich tradition. Previously, all fish was evaluated for freshness and priced accordingly.

An essential element of quality control
The need for organized sensory evaluation of raw materials in the purchase of raw materials and production and evaluation of products is growing both due to the demands of buyers from abroad and no less because food companies are adopting quality management. Systematic methods of sensory evaluation and recording of sensory evaluation results on raw materials, production and products are an essential part of quality control.

Milk and dairy products are a sensitive product and the use of sensory evaluation in quality control has a rich tradition. All meat in slaughterhouses is evaluated in quality categories according to construction type, meat filling and fat. For each type of meat, there are special rules for quality assessment. This assessment is first and foremost a visual and contact assessment of the meat assessor, even though he has a device such as a fat meter to rely on.

An important part of Matís' operations
Sensory evaluation is an important part of Matís' operations and is also mainly used in quality control and product development at Icelandic food companies. For many years, Matís has assisted companies in developing sensory evaluation, provided advice in sensory evaluation and carried out shelf life research in cases where sensory evaluation is a very important factor.

Sensory evaluation has been used in various research projects, both domestic and foreign. Matís' staff has provided theoretical and practical instruction in sensory assessment at the Department of Food Science at the University of Iceland and at the fisheries department of the University of Akureyri's resources department. Matís' staff has also taught sensory assessment at the United Nations Fisheries Academy since 1998. Matís has also held various sensory assessment courses for employees of fish processing companies and other food companies.

Perfect facilities at Matís
Matís has very perfect sensory assessment facilities, with a special sensory evaluation room with separate booths, perfect lighting and ventilation. There are also good facilities for handling food and preparing samples and this is very useful for seminars and teaching.

Development of new methods
In recent years, work has been done on the development of new sensory evaluation methods, especially for sensory evaluation of whole fish. The method that fish researchers in Europe agree will be most suitable for fresh fish food is the so-called QIM quality factor method. This method is very suitable for teaching and training and coordination of assessments and it should be noted that in 2003 all fish market staff in this country were trained in this method.

Matís is a partner in QIM-EUROFISH, which works to harmonize sensory assessment methods for fish. Finally, Matís also participates in the European Sensory Network, which is a collaborative platform for universities, institutions and companies in Europe in the field of sensory assessment.
