Shulou(Shulou.com)11/24 Report--

On the evening of October 10, TCL officially launched a "global leader" flagship refrigerator product-TCL lattice refrigerator Q10. As the benchmark for the 25 anniversary of TCL White Appliances, the biggest selling point of this product is the molecular fresh-keeping technology jointly developed with the School of Food of Jiangnan University, which is the number one in the field of food science and technology in China.

Molecular fresh-keeping technology is the first time to realize the application of magnetic field in food preservation. In fact, this technology comes from the magnetic field preservation technology, which should be used in large-scale fresh cold storage, to slow down the metabolism of microorganisms, cells and molecules through magnetic field, so as to improve the freshness of seafood, meat and other ingredients.

Although the magnetic field fresh-keeping technology has a good fresh-keeping effect, it is difficult to apply to the consumer market because of the complex structure, the difficulty of precise control and adjustment of temperature and magnetic field in space, high energy consumption and cost.

In the face of this difficulty, TCL's white home appliance R & D team worked closely with the School of Food of Jiangnan University, and through the in-depth cooperation and research of excellent professors and doctoral experts in the food field, TCL finally achieved a technological breakthrough and successfully carried it on the refrigerator and named it "Molecular fresh-keeping Technology".

The molecular fresh-keeping technology carried by TCL refrigerator Q10 can deeply regulate the movement of molecules in food cells through a biological magnetic field, so that cells are closely arranged to form a protective layer to prevent the loss of nutrients, while keeping cells and molecules moving at a low speed, reducing metabolic loss, and finally achieving a better locking and fresh-keeping ability.

At the bottom of the fixed freezer is a separate molecular fresh-keeping chamber. The molecular fresh-keeping cabin uses the "PUSH" door opening mode, and there is a touch button at the top, which can be clicked to switch to the corresponding fresh-keeping mode, including molecular fresh-keeping, chilled, fresh and mother-to-baby, etc.

Here, you can store some valuable ingredients, such as matsutake, bird's nest, caviar and so on, as well as fresh fruits, vegetables, seafood and so on. In a word, molecular fresh-keeping chamber can act on all ingredients. Compared with traditional preservation, molecular preservation can reduce metabolic loss and prolong the preservation cycle.

Molecular fresh-keeping chamber containing black and white truffles according to officials, with the help of molecular fresh-keeping technology, spinach can not wilt for 7 days, and the weight loss rate is less than 8% for 7 days. The growth of beef microorganisms is 50% lower than that of ordinary refrigerators. Strawberries are still bright red for 15 days. In 10 days, the anthocyanin content of blueberries increased by 4%, 20% higher than that of ordinary refrigerators for 3 days, and the loss of salmon juice was less than 1%.

Is it really that amazing? In order to verify the "molecular fresh-keeping" ability of TCL lattice refrigerator Q10. First of all, the author selected the cut apple for testing. As we all know, once the apple is cut, it is easy to oxidize, and the moisture is easy to volatilize and deteriorate over time.

The author put the cut apple in the molecular fresh-keeping chamber, tested the apple weight before putting it, stored for 4 days, then took it out, tested the apple weight again, and finally got the following results:

In 4 days, the apple lost only 0.5g in weight and 0.46% in water loss, which is basically negligible.

Take a close look at the cross-section of the apple, even if it has been stored for 4 days, there are only slight signs of oxidation, the flesh is still full, moisture is sufficient, a bite, the taste is still crisp, and there is no difference when you just bought it back.

Let's take a look at blueberries.

Also kept in the molecular fresh-keeping chamber for 4 days, the weight loss was only 0.1g, and the water loss rate was negligible.

In fact, in addition to the above four "experimental group" blueberries, there is also a whole box of blueberries in the molecular fresh-keeping chamber, which has been stored for nearly 10 days since it was bought from the supermarket. It is no exaggeration to say that at this moment, the taste of blueberries is no different from that just picked. The flesh is still firm, the juice is rich, and the taste is sweet and sour.

If you use an ordinary refrigerator for cold storage, for so many days, the phenomenon of decay and mildew would have appeared long ago.

The author also tested the cut oranges, the storage time is also 4 days, the weight loss is only 1.7g, the water loss rate is only 1.21%.

Four days later, the orange was taken out, and even the juice remained on the cross section, and the fruit was crystal clear.

For example, the broken pomegranate was placed for a full 7 days, and the pomegranate flesh was still fresh and juicy, as if it had just been broken.

Generally speaking, for some families who like to "hoard", with molecular fresh-keeping technology, some fruits and vegetables rich in water and VC can greatly reduce the loss of nutrients such as VC and anthocyanins, and lock in fresh nutrients firmly. There is no need to worry that long-term storage of uneatable vegetables will lead to decay, wilting and uneatable; for example, families who like to eat beef can buy a large amount of beef at once and store it through "molecular preservation". You can eat delicious, protein-rich beef every day.

In addition to the molecular fresh-keeping chamber, the temperature control performance of the fixed cold room was tested by temperature and humidity sensors.

The author puts one end of the sensor in the refrigerator cabin and records the temperature and humidity in the cabin every 5 minutes. in order to ensure the rigor of the data, the testing time is more than 6 hours, and the door is not opened and the refrigerator is not cut off during the test.

The temperature and humidity data of the fixed cold room are shown above, and the temperature of the fixed cold room is set to 5 °C. the test results show that the average temperature of the fixed cold room is about 3.6 °, the error is about 1.4 °, the lowest temperature is 2.9 °and the highest temperature is 6.6 °. The graph at the bottom of the table shows that the temperature fluctuation in the cabin is basically a straight line, with no obvious fluctuations up and down. This proves that the TCL refrigerator Q10 has a more accurate temperature control performance.

More accurate temperature control performance also means better cold storage capacity. Therefore, the author also tested the fresh-keeping effect of TCL lattice refrigerator Q10 fixed freezer on common vegetables and fruits.

In order to better highlight the fresh-keeping ability, the author chose the control experiment:

The tested vegetables were divided into two groups, in which the fresh-keeping group was stored in the TCL refrigerator Q10 fixed cold room, and the control group was stored at room temperature. Five days later, we tested the weight of the two groups of melons, fruits and vegetables again, and got the comparison results.

Cucumber:

Weight change of cucumber stored in TCL refrigerator Q10 for 5 days

The weight change of cucumber stored at room temperature for 5 days: the weight loss of refrigerated cucumber is 3.6g, and that of cucumber at room temperature is 27.4g. According to the formula of water loss rate, the water loss rate of the former is 3.24%, while that of the latter is 25.2%. The comparison results show that the locking effect of TCL refrigerator Q10 is very excellent.

Green pepper:

Weight change of green pepper stored in TCL refrigerator Q10 for 5 days

The weight changes of green pepper stored at room temperature for 5 days were summarized as follows: the weight loss of refrigerated green pepper was 0.1g and that of room temperature was 7.7g. The water loss rate of the former was negligible, while that of the latter was 5.3%.

Carrots:

Weight change of carrots in TCL refrigerator Q10 after 5 days

A summary of the weight changes of carrots after 5 days at room temperature: the weight loss of refrigerated carrots is 21.7g, and the water loss rate is 9.7%; as a comparison, indoor carrots lose weight 91.9g, and the water loss rate reaches 34%.

Cut pumpkin:

Summary of the weight changes of pumpkins stored in TCL refrigerator Q10 for 5 days: the weight loss of refrigerated pumpkins is 36.6g, and the water loss rate is 14.8%, while the pumpkins stored at room temperature have rotted and cannot be compared.

Through the comparison of the above different vegetables, it is obvious that the fresh-keeping effect of TCL refrigerator Q10 is very good, and the water loss rate is low, so even if it is stored for a week, melons and vegetables can still maintain a relatively good fresh state.

In addition, the TCL lattice refrigerator Q10 also supports core functions such as independent three-system double-wide temperature change, GP + photoelectric ultra-clean technology, 10-minute rapid deodorization, minus 32 ℃ cryogenic locking and so on. With regard to this product, CTOnews.com has made a more in-depth and comprehensive evaluation. Interested partners may wish to click here to learn more.

Written in the end: through the experiment, we have to admit that the TCL lattice refrigerator Q10 does have excellent fresh-keeping and locking ability. Normally, the fixed cold room of TCL refrigerator Q10 can meet the daily fresh-keeping needs of ordinary families. Of course, if you have a more stringent demand for fresh ingredients, then Q10, which can be "molecular fresh-keeping", will certainly satisfy you. It can actually improve the "shelf life" of fruits and vegetables and other ingredients. Once the ingredients enter the molecular fresh-keeping chamber, it is like entering the "dormant warehouse". Put it in and take it out, even after several days apart, but the change in the ingredients is minimal.

Hoarding, but also to "hoard fresh", the pursuit of high-quality life of you, TCL grid refrigerator Q10 must be an unavoidable choice.
