Study investigates sensory properties of ice cream with fish powder

Posted On: March 4, 2011

Ice cream enriched with fish proteins may be acceptable after production, but storage is a problem, according to new research.

The study, published in Journal of the Science of Food and Agriculture, investigated the effects of enriching the frozen confectionery product with fish protein to enhance its nutritional value.

The authors, from the University of Iceland and the Iran Fisheries Research Organization (IFRO), found that that enriching ice cream with fish protein powder did not influence the sensory or chemical characteristics of the products after production, however unwanted attributes including fish flavour and off-odour were increased after more than 2 months of storage.

“The objective of this work was to study the influence of fortifying ice cream with fish protein on chemical characteristics and sensory quality of the product in order to provide some useful information to food industry on how to develop such products and with the specific aim of increasing fish protein consumption,” said the authors, led by Dr Gholam Shaviklo.

“From the results it can be concluded that ice cream with fish protein can have good sensory quality for up to 2 months after production,” they added.

UMBC’s Department of Marine Biotechnology: creating sustainable fish farms that may revolutionize notions of fishing and seafood

Posted On: February 15, 2011

In UMBC’s Department of Marine Biotechnology, Yonathan Zohar and his colleagues are creating sustainable fish farms that may revolutionize our notions of fishing and seafood.

Zohar is chair of UMBC’s new Department of Marine Biotechnology. At the Columbus Center, he and his colleagues develop new techniques and technologies to protect the world’s oceans and seas and preserve the life inside them.

Zohar and his colleagues think they have an answer: a sustainable aquaculture system that they have developed in the Columbus Center’s basement. It uses a system of filters and pumps to clean and recirculate artificial seawater, providing ideal conditions for marine fish to grow and breed in safety. The fish can’t escape, and the design eliminates the risk of transmitting diseases or polluting coastal waters. Even the fish wastes are put to productive use: they are converted to methane, which can be used to help power the whole aquaculture system.

The aquaculture system developed by Zohar and the marine biotechnology team has already been licensed to a private company for commercial production.

Florida: PetroAlgae Protein Concentrate Confirmed as Replacement for High Quality Fishmeal in Tilapia Farming by University of Idaho Study

Posted On: November 6, 2010

PetroAlgae Inc., a leading renewable energy company that licenses its commercial micro-crop technology globally, announced that a third party study done by the Aquaculture Research Institute at the University of Idaho has found that PetroAlgae protein concentrate (PPC) produced as a co-product along with the renewable fuel feedstock by the company’s micro-crop technology system can replace menhaden fishmeal protein at levels up to 100% in feeds for tilapia.

“We are very encouraged by the results of this extensive study because they point to PetroAlgae protein as a highly desirable replacement for fishmeal at a time when feed demand is expected to increase dramatically in the face of limited traditional supply,” said Dr. Ronald W. Hardy who conducted the study.

The study also found that PPC would be suitable as a fishmeal replacement for other farmed fish species. According to the study, tilapia is one of the largest-volume farmed fish species, and tilapia production is expected to grow from 2.8 million tons to more than 9 million tons by 2020, requiring 13 million tons of feed (up from 8 million tons in 2010).

Bluewave Marine Ingredients gets GMP for fish protein plant

Posted On: November 1, 2010

Fish protein producer Bluewave Marine Ingredients has announced its joint venture operation in Ecuador has received GMP certification from SGS.

The recently formed company produces fish protein isolate at half the price of canned or frozen fish methods, and allows for the inclusion of protein in powder form for products including breads, pastas and soups.

“This is an important milestone for the Bluewave Ecuador site – as it assures the world that PerfectDigest Peptides are made according to sanitary requirements for both human and animal consumption applications,” said Mark Rottmann, COO for Bluewave. “We recently passed the 1,000 ton mark in terms of Peptide production, this registration will allow us to further expand into critical export markets.”

Scientist in Hawaii Create New Fish Feed Out of Fish

Posted On: October 7, 2010

Fish byproducts may be a new source of fish feed, thanks to research by U.S. Department of Agriculture (USDA)-funded scientists in Hawaii.

Research scientist Dong-Fang Deng and her colleagues with the Oceanic Institute in Waimanalo, Hawaii, are collaborating with USDA food technologist Peter Bechtel to develop the new fish feeds. Bechtel is with the USDA Agricultural Research Service (ARS) Subarctic Agricultural Research Unit in Kodiak, Alaska. ARS is the USDA’s principal intramural scientific research agency.

The scientists are taking fish parts that would normally be discarded—head, tail, bone, skin and internal organs—and fashioning them into feeds for shrimp and fish. They are currently testing the feeds on Pacific threadfin (Polydactylus sexfilis)—or “moi” as Hawaiians call it—and Pacific white shrimp (Litopenaeus vannamei).

Marine Ingredients Poised For Accelerated Development

Posted On: May 6, 2010

Inside Cosmeceuticals posted an editorial feature we recently wrote on the future for Marine Ingredients.  Read more below:

————————

Many believe the ocean is where life first started. Then it is no surprise, perhaps, that the biggest potential source for new, bioactive ingredients for the health and beauty market may originate from the same place. With so many new species of marine life still to be discovered, the potential for new marine-derived compounds and extracts is immense, and the industry is poised for accelerated development in the near future.

Later this year, the final results of the Census of Marine Life will be revealed. This 10-year ambitious initiative, driven by a global network of researchers in about 80 nations, is intended to assess and explain the diversity, distribution and abundance of marine life in the world’s oceans. This massive study will tell us about newly identified marine organisms and marine life not previously known. This news is exciting, as new promising bacteria, organisms and compounds will be likely discovered, providing a potential treasure trove of new marine ingredient products.

Work on utilization of seafood byproducts continues in Alaska

Posted On: May 4, 2010

Last November, Chilkoot Fish and Caviar Inc. of Haines was hit with a complaint by the EPA that could cost the company the maximum civil penalty of $177,500 for continuously violating its waste discharge permit under the Clean Water Act over a period of four years.

In January 2007, Deep Creek Custom Packaging Inc. of Ninilchik was fined $10,500 by the EPA, also for improperly disposing of fish waste.

Under Clean Water Act regulations, fish processors must grind their waste to a size of a half-inch or less before discharge. Even under proper disposal, however, fish waste can impact the environment by creating “dead zones,” essentially sucking out oxygen needed for live fish to thrive.

The crackdown on fish waste discharges is of special concern for small companies that process less than 25 tons per day that cannot afford the multi-million dollar price tags for equipment deployed at large-scale operations that separates, dries and grinds waste into fishmeal for sale as a byproduct to the agriculture and aquaculture industries.

This is where entrepreneurs like Sandro Lane and Leo Pedersen and scientists such as Scott Smiley and Peter Bechtel come in. Lane and Pedersen have found creative ways to simultaneously turn previously discarded fish waste into economically valuable products while aiding small processors.

Marine proteins shown to be effective to support weight gain in poultry

Posted On: December 2, 2009

The Bluewave Marine Ingredient company in Peru reports that they have had some successful trials using their PerfectDigestTM marine peptide to improve feed conversion and weight gain in poultry. The study, conducted at the  Bangkok Animal Research Center (BARC), showed in an 800 bird matrix that their product provided nearly a 2% FCR improvement and a 3.3% growth improvement in poultry over the initial 10 day trial.

Blue Waves products range in price starting at $1.0/kg for a liquid protein concentrate, and up to $4.5/kg for a protein isolate powder, ex-works.
