How to reduce the risk of parasites
Many people think that it is better to eat more mustard because they are afraid of parasites in sashimi. Don't underestimate parasites, whether mustard or other spices are difficult to kill. Soaking in a certain concentration of mustard for 45-55 minutes can effectively kill parasites, but we only dip it at most, how can we soak it for so long! The so-called certain concentration, in the experiment, is 1-3g/ml. Do you really mix this thick mustard sauce when you eat sashimi?
In addition, scientists who care about this group of foodies have also studied the efficacy of various seasonings on parasites. Forget about vinegar and soy sauce. Parasites live by the day, but high-concentration liquor will kill parasites within half an hour. Therefore, the general public who eat sashimi dipped in mustard soy sauce should not fantasize that spices can kill insects. To prevent parasites, choose ingredients.
1. Choose cultured deep-sea fish, and don't feel particularly tall when you hear the word wild. Deep-sea culture is the source to curb parasites, and 75% of the fish imported from Norway, Scotland and Chile belong to deep-sea culture.
The whole process, from artificial fertilization of parent fish, to fresh water culture of fry, to seawater culture, to fishing and packaging of adult fish, is strictly and accurately controlled scientifically. The control of feed and environment, the inoculation of fry, the strict disinfection of fishermen and the quarantine of import and export customs make these cultured fish have high safety.
2. Rapid freezing is one of the most effective methods to eliminate parasites. The treatment of fish is the second line of defense against parasites after choosing cultured fish. Heating is the best way to kill parasites.
The FDA's suggestion is to freeze at -20℃ for seven days, and at -35℃ for 15 hours, while the EU stipulates that it should be frozen at? Keep it below 20℃ for 24 hours to kill parasites. In a word, freezing is a very effective means to kill parasite larvae and eggs.
