A new method to make oysters easier to open is being developed in South Australia.
The method, developed by Simmonds Seafood Marketing Agencies involves shaving the lip of the oyster to create a small opening where a knife can later be inserted to greatly simplify the shucking process.
The opening is immediately sealed with wax to keep the juices in and the oyster alive.
Inventor and oyster marketer Bob Simmonds said the wax coating also provided branding opportunities because it allowed stickers to be applied that provide information about providence and packing dates.
He said the ability to keep oysters alive while making them easier to open gave them a much greater shelf life compared to the typical pre-shucked product.
“Most oysters are opened, half shelled and then sent to restaurants and hotels. You only get three or four days life out of the product whereas with the new process you probably get 10 to 12 days life out of the product, which is a huge benefit,” Simmonds said.
Trading in Adelaide as Oyster Bob, Simmonds sells 18 to 20 million oysters a year on behalf of South Australian oysters farmers, who produce about a third of Australia’s harvest.
Simmonds has entered a partnership with the Fisheries Research and Development Corporation (FRDC), which now owns the worldwide patents for the procedure, and is working to develop machines to streamline the process.
Appetite for live seafood
He said the easy-open oysters would be ideal for the Asian market because of its appetite for live seafood products.
Australia exports more than $1 billion of seafood a year to Asia, driven by strong demand for rock lobster, tuna and abalone.
“All the oysters that are sent out of Australia have been whole live and they are opened overseas but it’s a very laborious task,” Simmonds said.
“If we can take that part of it out of the equation and have an oyster ready to eat, that’s going to appeal to a whole lot of areas – especially China and Asia where they like live product.
“It can be opened live at the table and people can see the branding and have a discretionary taste of it just like they do with a bottle of wine.”
Robotics and laser technology
Simmonds and the FRDC have secured grants to develop three machines to realise commercialisation.
Oysters processed using the new method could be on the shelves in about a year.
“The product itself performs. It’s now about getting the numbers up,” Simmonds said.
“We’re looking at robotics and laser technology.”
In 2013-14, Australia produced 11,402 tonnes of oysters with a value of about $90 million.
Simmonds said as well as having great potential for export, the new method also was ideal for the retail market.
He said cooking shows on television had created an appetite for freshness among home cooks and made people more adventurous when it came to news ways of serving food.
“Now at retail level we can put them in a dozen pack and people can take them home and open them themselves easily at a dinner party or whatever it may be,” Simmonds said.
“It’s also the novelty factor of doing something a bit different too. Having it live at the table and branded are the essential ingredient to me.
Simmonds said the machines could be potentially sold commercially to other oyster processors once the process was perfected.
“The FRDC and I both believe this is one of the best things to happen to the oyster industry as far as marketing is concerned for a long, long time,” he said
“I don’t say it’s ever going to replace the current method but it’s just another string to the bow.”
