Oysters in Vân Đồn are mainly Pacific oysters, and raised under the model that employs rafting and dropping ropes. Oysters are molluscs that only feed on planktons and algaes in sea water, so there is no need to feed during the farming process. Instead, farmers monitor and check the oyster ropes regularly to make sure their oysters are healthy and grow normally. After 4-5 months of submerging in the natural environment, oysters grow to about 7-10 cm in length, and 60-80 grams in weight, which are commercial standards for harvesting. At this time, the oysters have grown thick and rich in nutrients such as magnesium, zinc… After separating the mature oysters from the clinging materials, the oysters are transported to the seafood port and taken to processing plants to undergo the production process on the same day.

Oyster processing

At the oyster processing factory, workers wash the mud and soil on the oyster shells by scubbing the oyster shells with a brush. As a result, when shelling, bacteria are not cross-contaminated into oyster meat. The shelling process is done by hand skillfully so as not to break the shell pieces into the meat. Oyster meat is rinsed with dilute salt water to clean the slime and then get sautéed. The sautéeing (or stir-frying) duration is about 15 minutes at a temperature of 140-150 degrees Celsius. After stir-frying process, oyster meat is dried, shredded and transferred to the stage of mixing with shrimp and pork floss in a certain ratio.

Oyster floss is packed into jars and pasteurized for 4-5 minutes at a temperature of 150 degrees Celsius, then labeled and transported to the market. During the process, workers must wear disinfected work clothes, gloves, and masks. Machines and tools such as tubs and trays are cleaned before and after use.


Oysters have high nutritional value, rich in zinc, low in fat, and do not contain bad cholesterol, which then help reduce cardiovascular risk, increase vitality and increase immunity for the body. Standard oyster floss looks spongy like pork floss, has a typical sweet and fatty taste of oysters but does not have fishy smell. Oyster floss is often served with congee, sticky rice, bread, rice, suitable for both adults and children aged 3 years and older. .
