How do I store DHA? How to store DHA?

Low temperature and vacuum are favorable conditions for the conservation of species in space. "It all starts with the characteristics of DNA. Zhang Dewen, a distinguished researcher and doctoral supervisor of the School of Basic Medical Sciences of Xi'an Jiaotong University, explained that from a biochemical point of view, DNA is a "bead chain" of biological macromolecular compounds, and each "bead" strung on it is a nucleotide, and the "thread" strung up is phosphoric acid.

The reason why DNA stores the information of life is that the nucleotides are different, that is, the four bases A, T, C, and G that make up it are arranged in different order, and these base codes are like words that record heritable information. It's DNA hydrolase. As soon as the DNA molecule touches it, the phosphodiester bond is severed, just like a chain breaks, the beads fall to the ground, and the order in which the information can be expressed is gone.

DNA hydrolase enzymes are all derived from living organisms and are widely distributed on Earth along with microorganisms, so DNA can only be left out for a few days at room temperature. DNA is very sensitive to both acids and bases. Free metal ions catalyze the reaction of DNA and eventually denature, so the pH needs to be constant or not too swinging in the DNA preservation solution.

The DNA used in the laboratory in the short term needs to be stored in a buffer solution, which means that the solution can "tolerate" the ions that determine the pH. Cryopreservation is still the most widely used method for DNA preservation.

DHA, whose full name is docosahexaenoic acid, is a polyunsaturated fatty acid, which is easy to oxidize and is better preserved in a cool place and protected from light.

The DHA bought for children is generally capsule, and it is stored indoors in the dark. I just took a look at the DHA of Bei Chubao that I am eating now, the bottle mouth is sealed with aluminum foil, and there is a moisture-proof agent in it, just store it normally, anyway, a bottle will be eaten quickly.

Lejia Shanyou imported algal oil DHA from the United States, there are two types of pregnant women and infant children, and they can be stored at about 20 degrees at room temperature and protected from light. No need to go out of your way to the refrigerator.

It is best to store the algal oil DHA products purchased in a cool place away from light, and do not stock up too much at one time. Because algal oil DHA is more susceptible to the influence of environment and temperature, it is relatively easy to oxidize. Therefore, as much as possible, choose algal oil DHA products with good brands and packaging technology, and then use the algal oil DHA as soon as possible after opening the bottle.

Parents who like to hoard things, buy enough for one stage at a time, and buy new ones after eating enough for one stage, don't overstock.

The raw material of natural Dr. DHA algae oil is selected from Life'sDHA imported from the United States of America's rare dinoflagellates (T oil), with high absorption rate, almost no EPA, plant seaweed extraction, pure algae oil presents a high-grade and rare "amber color", not mixed with other miscellaneous oils, almost no fishy smell, fresh taste, and does not affect the development of baby's taste buds.

Each capsule is 100mg, each capsule is individually blister-packed, clean and hygienic, non-sticky, and it is very convenient to take and eat at any time.

Natural Dr. DHA algae oil ranks first among the recommended products of a variety of DHA algae oils in the horizontal screen of the professional maternal and child institution "Little Safflower Evaluation"; Celebrities Wang Zulan, mother and baby celebrities, rice cake mothers, etc., have all been recommended on Xiaohongshu and Douyin. Celebrity mother Ella Chen Jiahua recommended DHA algae oil for babies. At present, it is available on Tmall***, JD.com*** and nearly 20,000 offline mother and baby stores across the country.

Good nutrition for babies, the key is before the age of three. 0-3 years old is a critical period for the development of the baby's brain and eyes, and DHA is crucial for the development of the brain and vision.

The best way to store DHA is to keep it fresh in the refrigerator. If it's winter, the temperature at home is not high, and it's okay to put it in the room, but if you turn on the air conditioner, put it in the refrigerator. The temperature is already high in summer, so it is better to put it in the refrigerator, otherwise the temperature is too high and the DHA will melt outside, and it will be soft when pinched, and the feel of putting it in the refrigerator is completely opposite.

No, as long as it is placed in a cool and dry place, especially in summer, do not put it by the windowsill, it is better to put it in the refrigerator in summer, and the high temperature outside will still have an impact on its shelf life.

The level of DHA in the body directly affects the proliferation of brain cells, nerve conduction, and the growth and development of synapses. In the experiment on the neuroprotective effect of DHA, it was found that DHA and EPA have good antioxidant effects and can effectively reduce the incidence of mental diseases.

If an infant is deficient in DHA during the growth stage, it can lead to retardation or hindrance in the development of the infant and retina, resulting in mental retardation and visual impairment.

No, as long as it is placed in a cool and dry place, especially in summer, Le Fuzhi should not be placed by the windowsill, it is best to put it in the refrigerator in summer, and the high temperature outside will still have an impact on its shelf life.

No, as long as it's not sun exposure.

Full-term, breastfed babies: No additional supplementation is required, and mothers need to ensure a daily intake of 200mg of DHA.

Babies who are not breastfed or do not have enough breast milk: Drink formula containing DHA.

Preterm infants: The American Academy of Pediatrics recommends 21 mg/kg of body weight for preterm infants born at birth and 18 mg per kilogram of body weight for preterm infants born with less than 1500 g of body weight.

Young children: Dietary supplements are the main food, and dietary adjustments can be made to meet their needs by eating some foods rich in DHA. You can eat 280 350 g of fish per week, and you can eat fish for 2 or 3 meals a week, and more than 1 meal is seafood with high fat content.

Therefore, premature babies and babies who cannot consume enough DHA through diet need to buy additional DHA supplements, but the dosage must be in accordance with the doctor's instructions, and reasonable supplementation can be effective.

DHA is only found in fish and a few shellfish, and fish with high DHA content include tuna, bonito, salmon, mackerel, sardines, horse mackerel, flag orange fish, tuna, yellow croaker, saury, eel, hairtail, crucian carp, etc., and the DHA content per 100 grams of fish can reach more than 1000 mg. For a certain type of fish, eye socket fat is the first part of the fish with high DHA content, followed by fish oil.

Other foods such as cereals, potatoes, cream, vegetable oil, lard, vegetables and fruits contain almost no DHA.

Therefore, from the perspective of nutrition and brain health, if people want to get enough DHA, the easiest and most ideal way to have a round delay swimming effect is to eat fish. The most abundant content in the fish body is the eye socket part, followed by fish oil.

DHA Attention Bai Matters:

Under normal circumstances, there is no special restriction on DHA supplementation for babies within a day, morning DAO or evening are versions, DHA itself can not be synthesized, so it is necessary to supplement from the outside, DHA is easy to be decomposed in stomach acid, so it can be taken before feeding or taken together with meals. The ** of DHA is mainly breast milk, formula milk powder, some fish, dried fruits, etc.

I think science or something is reliable and reliable, it is not reliable or reliable, people act according to themselves, they can't always imitate imitation, even picky eaters have to imitate it, it's strange to imitate it, what do you like to eat The result of evolution can be much earlier than science, how can there be animals in nature who are afraid of even eating! Fearful, although it will avoid some problems, but I feel that I have lost something important.

Start taking it at the 25th week of pregnancy, start to give the baby one month after the baby is born, 100 mg per capsule a day within one year of age, and the appropriate amount can be recommended according to the baby's eating habits over one year old. The baby's brain development is 0-6 years old and can be eaten all the time.

BAI matters.

If you are financially allowed, it is recommended that the baby and the mother.

DAO also replenishes DHA for better results! 1.In the case of full breast milk, the baby is fully breastfed, and the mother directly supplements the effect.

2.The amount of breast milk is relatively small, and the baby is mainly a milk powder, and the baby's direct supplement is more effective than the mother's supplementation.

Summary. Hello, DHA shelf life is generally 2 years, DHA is docosahexaenoic acid, commonly known as brain **, is a very important polyunsaturated fatty acid for the human body, belongs to the omega-3 unsaturated fatty acid family of important members. Hope it helps.
