Shellfish Waste May Give Us “Vanishing Plastic”

Admin — Thu, 22 Jul 2010 19:53:09 +0000

Prototype biodegradable plastics are possibly just months away, spelling good news for the worsening headache of plastic packaging, which accounts for up to 25 per cent of municipal landfill.

Researchers at Swinburne University have been investigating the use of bioplastics – ingredients from renewable sources – and the properties of biopolymers that determine their ‘compostability’.

These projects have brought together PhD students, Suchetana Chattopadhyay and Cameron Way, who are examining the properties of plastics biopolymers as part of their PhD studies, under the supervision of Associate Professor Enzo Palombo.

Chattopadhyay is using a respirometer – a composting machine – to test novel, chitin-based polymers.

Chitin is the world’s second most abundant organic compound. It is mostly derived from shellfish waste, but also includes the exoskeletons of crustaceans, insects and spiders.

In collaboration with an industry partner, Chattopadhyay has provided the first direct evidence of true biodegradability in novel, chitin-based polymers.

Ongoing Project Aims to Recover Nutritional Value From Seafood and Brewing Waste

Admin — Mon, 19 Jul 2010 16:47:27 +0000

Preliminary findings from a UK government funded project focused on extracting value from seafood and beverage processing waste shows the process could potentially recover nutritional components such as glucosamine.
The process involves an ionic liquid (IL) extraction process which selectively recovers targeted high value components under mild conditions. Ionic Liquids are clean, inexpensive solvents whose properties can be tailored for recovery of specific target molecules. Recycling of recovered components for applications in pharmaceutical, nutraceutical and chemical markets will deliver both economic and environmental benefits to technology adopters.

C-Tech Innovation, a UK based technology development company, is leading the three year EXCIL project that involves collaboration with key stakeholders including Heineken UK, seafood processor West Coast Sea Products, GlycoMar Ltd., the Sea Fish Industry Authority, waste management firm SITA UK and Imperial College London.

The research is being by funded by a UK government agency, the Technology Strategy Board, with the stated objective being to provide a new approach to solving the environmental and financial costs involved in disposal of food and brewing waste through a sustainable and resource efficient method.

EXCIL is a 3 year project which started in October 2009.

Ocean Nutrition Canada (ONC) Adds New Omega-3 Microencapsulation Technology to Portfolio

Admin — Fri, 16 Jul 2010 22:07:22 +0000

Ocean Nutrition Canada (ONC) has added a new microencapsulation technology to its offerings buy purchasing a five-year license to the fish oil business and encapsulation technology of Austrian tech firm, GAT Food Essentials.

The undisclosed deal will see the Canadian fish oil leader take exclusive rights to GAT’s wowCAPS technology that has proved particularly suitable to dairy formulations, although ONC’s own PowderLoc encapsulation technology has had success there too.

ONC will also take control of GAT’s existing customers in the fish oil space, with there being potential for the two to work together on research and development and formulation.

Chitin in anti-aging formulations

Admin — Wed, 23 Jun 2010 12:14:14 +0000

Technical paper by author Yash Kamath: Skin aging leads to decline in its functions such as increase in trans-epidermal water loss (TEWL), decrease in the production of collagen,elastin and the extracellular matrix (ECM). The overall effect is the thinning of the skin, dryness, and wrinkling. The ECM acts as a material transport medium for the cellular entities like the keratinocytes in the epidermis and fibroblasts in the dermis. Environmental factors damage the skin chemically by generating reactive oxygen species (ROS) and free radicals.

The protection of skin from these insults requires a group of actives consisting of cell protectants, antioxidants, and immunomodulant compounds. In this technical paper the authors have found that the concoction of these ingredients in the form of an emulsion works much better when chitin nanocrystals (nanofibers) are added. A number of factors indicative of anti-aging effects, such as fibroblast proliferation, collagen increase, ATP production etc. are significantly improved by the addition of chitin. The effect is attributed to the biocompatibility of products of chitin breakdown. It can promote the synthesis of hyaluronic acid. Penetration of chitooligomers generate glucosamine and N-acetyl-glucosamine which are incorporated into the ECM by phosphorylation.

Bayou La Batre Breaks Ground on Seafood By-Product Processing Facility

Admin — Fri, 04 Jun 2010 15:59:10 +0000

Members of the Gulf Coast Agricultural and Seafood Co-op, along with elected officials and guests, break ground today on an eco-friendly seafood by-product processing facility that will ultimately provide products for commercial application to the fertilizer, poultry and pharmaceutical industries. The facility will also create new jobs in Bayou La Batre, Ala.

In 2009, the U.S. Department of Commerce jointly awarded the Alabama Farmers Market Authority and the Mobile County Commission a $3.2 million grant to help pay for the facility. Total cost of the project due for completion in January 2011 is $6 million.

Seafood Byproduct Seminar in Ireland mid June

Admin — Thu, 03 Jun 2010 15:47:29 +0000

The Irish Farmers Assoiciation (IFA) Aquaculture and the Irish Sea Fisheries Board, Bord Iascaigh Mhara (BIM)’s Aquaculture division will host a special seminar in the Sheraton Hotel, Athlone on June 16, starting at 11.00am.

The seminar will be open to all seafood processors and aquaculture operators and will look at the two main issues on by-products through specialist talks and discussions: 1. Regulationof by-products and 2. Options and opportunities for disposal / sale.

Options for the industry for alternatives to rendering of seafood by-products are gradually coming on stream, including incineration, composting, anaerobic digestion and transformation into technical products. All of these areas will be looked at in detail at the seminar.

Novel process allows ‘highest quality’ omega-3 concentrations

Admin — Wed, 26 May 2010 17:05:48 +0000

Novel technology allows KD-Pharma, the fully-owned subsidiary of health care products company Bioseutica, to produce what it claims to be the market’s safest and highest quality omega-3 concentrations.

Specific combinations of omega-3 EPA/DHA at concentrations of up to 99 percent are produced by the process, known as kd pür, which was designed, developed and patented the company.

This is achieved by advanced super critical fluid technology conducted under mild temperatures below 45 Celsius and under CO2 atmospheric conditions to extract, refine and concentrate highly purified omega-3s from fish oil.

The process is also said to remove other undesired components from omega-3s such as omega-6, saturated fats, cholesterol and contaminants.

Bioprocessing Data for the Production of Marine Enzymes Now Available

Admin — Fri, 21 May 2010 15:49:54 +0000

Abstract: This review is a synopsis of different bioprocess engineering approaches adopted for the production of marine enzymes. Three major modes of operation: batch, fed-batch and continuous have been used for production of enzymes (such as protease, chitinase, agarase, peroxidase) mainly from marine bacteria and fungi on a laboratory bioreactor and pilot plant scales. Submerged, immobilized and solid-state processes in batch mode were widely employed. The fed-batch process was also applied in several bioprocesses. Continuous processes with suspended cells as well as with immobilized cells have been used. Investigations in shake flasks were conducted with the prospect of large-scale processing in reactors.
