- Used to keep food fresh and prevent protein from deteriorating
For fresh foods such as fish and meat, protein deterioration will affect the freshness and taste of the food. Therefore, it is necessary to prevent protein deterioration during transportation and storage. Refrigerators can keep food fresh, but they are not very effective in preventing protein deterioration. The antistaling agent containing Vc-Ca can prevent the protein contained in fresh foods such as fish and meat from deteriorating, and its anti-deteriorating and maintaining freshness effect is not restricted by contact methods, such as spreading or spraying on food. Or you can immerse the food in a chemical solution, or you can put ice and other refrigerants into the solution at the same time, which is very convenient to use. For example, Masaji Ito et al. invented a chemical agent, the active ingredient of which contains acid salt or lysate, ascorbic acid or calcium ascorbate. According to the method of Bulletin Japanese Society of Fish, 24,749-750 (1959) of Saito et al., the freshness of fish is used to judge the constant as K, and the K value is determined as the effective time index for preventing protein deterioration. The K value represents the degree of protein deterioration. The smaller the K value, the lighter the degree of deterioration and the fresher the food. The inventor did the following experiment:
Example 1, Anti-sardine protein deterioration effect experiment. Example 2, “Mackerel” protein anti-deterioration experiment. Example 3, the anti-degeneration effect of mackerel protein. Example 4, the protein anti-deterioration experiment of roasted chicken. Example 5: Experiment on the anti-deterioration effect of beef and pork protein. By comparing the K values measured by the experiment, they found that the use of a preservative containing Vc-Ca can prevent protein deterioration for a longer period of time than the comparison without the preservative, and the fading of the sample is lighter than that of the comparison. Strong moisture capacity. As long as the appropriate preservative concentration and flooding time are selected, the anti-protein effect will be the same as the freezing treatment.
- Establish and maintain high levels of Vc in the human body.
Many workers have verified more than 300 metabolic mechanisms involving Vc, including the ascorbic effect that was first observed by Dr. Robert Lind in 1940, and the free radical scavenging reaction of antioxidants until recently discovered. Its clinical effects have been widely recognized, so people have no doubts about establishing and maintaining the effective concentration of Vc and its derivatives in the human body. However, because people lack synthetic Vc liver enzymes, the Vc needed must be taken in with food. However, if the ingested Vc does not participate in the metabolism in time, it will be excreted, that is to say, the human body has no ability to store Vc. This problem is solved by the invention of Markham·Richard G. He discovered a mixture consisting of a compound with Vc efficacy and at least one compound selected from the group consisting of L-threonine, L-lignoic acid, edible salt of L-lythreonic acid, and aldone-lactoic acid of. This mixture can establish a high level and high concentration of Vc in the human body, at the same time it can improve the body’s tolerance to Vc, and can enable the human body to more effectively absorb and retain Vc-derived compounds. 12 people have been tested. , Aged from 27 to 45 years old, the test results fully confirmed the above point of view.
- Supplement calcium for the organism
Regular intake of calcium products every day can effectively prevent osteoporosis, but this must be a long-term process. Consistently drink a sufficient amount of beverages such as tea or coffee with calcium sweeteners every day. The calcium sweetener has a neutral taste and is soluble in water. For example, calcium gluconate, calcium lactate, calcium levulinate, Vc-Ca, etc. The calcium salt content of calcium sweeteners is determined by the amount of calcium required per day and the amount of sweeteners taken per day. Generally speaking, in order to prevent osteoporosis, in addition to the normal daily calcium intake, another 500-1000mg calcium is needed. Calcium sweeteners are generally available in the form of tablets, ampoules, gels or capsules. Drinking tea and coffee with calcium sweeteners as required for a long time is very effective in preventing osteoporosis.
