lets you understand the food additives in aquatic products - phosphate
Phosphate is an essential mineral element for the human body. The main source of phosphorus intake by the human body is natural food or food phosphate additives, and phosphate is one of the natural ingredients of almost all foods. Because phosphates can improve or impart a range of excellent properties to foods, they were used in food processing more than a hundred years ago, and were widely used after the 1970s.
phosphate is one of the most widely used and most widely used food additives. It is widely used as an important food ingredients and functional additives in the processing of aquatic products.
phosphate in aquatic products
phosphate as a food additive, and has the functions of moisture retention agent, acid and alkali regulator, stabilizer , anti-caking agent , coagulant , leavening agent , etc. The main functions in aquatic products (especially frozen aquatic products) are as follows:
. Effectively improve the water holding capacity of seafood when thawing, make the gravy richer, and reduce the loss of moisture and nutrients;
. Reduce the loss of juice after thawing, reduce weight loss and fiber toughening during cooking;
. During the processing and storage process, it effectively inhibits fat oxidation and extends the shelf life of seafood;
4. Maintains the natural color and flavor of aquatic products;
5. Works in concert with sugars to effectively prevent protein denaturation caused by surimi products in the environment of too low temperatures.
phosphate exceeds the standard
phosphate is a common natural ingredient in food. A small amount of phosphate intake is less harmful to the human body. A large amount of phosphate intake may cause excessive phosphate concentration in the body, causing certain harm to the human body, including calcium deficiency, stones, and aggravation of other diseases.
. Calcium deficiency: Phosphate can be processed as a preservative. Adding it to food can improve the taste and freshness of the ingredients. However, the body consumes too much phosphate, which makes it easy for calcium to be fully digested and absorbed, because calcium and phosphorus are in a certain proportion in the body. If the phosphorus in the body is too high, calcium will decrease, resulting in calcium deficiency in the human body. Children and adolescents are prone to osteomalacia or rickets , adults are prone to calcium deficiency osteoporosis , elderly people are also prone to low back pain, as well as fractures, thoracic deformity , and short body year by year, etc.;
. Stones: The body consumes too much phosphate, and the proportion in urine will increase accordingly, which is prone to urination. Phosphate stones are formed in the system. urinary stones are harmful to the human body, such as blockage causes hydronephrosis , which compresses the kidneys and causes renal insufficiency, azotemia, uremia , etc.;
. Aggravates other diseases: Excessive phosphate concentration in the body will lead to imbalance in the proportion of calcium and phosphorus, which is prone to crystallization in the blood vessel wall and the inner wall of the heart, aggravates cardiovascular diseases such as hypertension or heart disease .
Customs supervision
Supervision method
Customs formulate annual national imported food safety supervision and sampling plan and special imported food safety supervision and sampling plan, including the testing of phosphate projects for aquatic products.
implements the standard
According to GB 2760-2014 " National Food Safety Standard Food Additives Usage Standard ", the usage limit of phosphate in frozen aquatic products is 5.0g/kg, frozen fish paste products (including fish balls, etc.) is 5.0g/kg, pre-made aquatic products (semi-finished products) is 1.0g/kg, and canned aquatic products are 1.0g/kg.
Customs reminder
Food importers find that imported food does not comply with the laws, administrative regulations and national food safety standards, or there is evidence to prove that it may endanger human health, they shall immediately stop importing, sales and use, implement recalls, notify relevant producers and operators and consumers, record the recall and notification, and report the food recall, notification and handling to the local customs.
