Still remember energetically does jack-tar wave compare the spinach can that likes most? And energetically jack-tar is same, a lot of people also like to have spinach.
But " the otherwise before spinach makes food should use boiled water scald " this one problem, however pose a lot of people. Someone says the careless acid content of spinach is high, boiled water scald should be used first before making food; Before someone says to make food, can make with spinach of boiled water scald the vitamin prediction of a person's luck in a given year of spinach.
So, should the otherwise before spinach makes food use boiled water scald?
Exceed elder brother to say today.
The answer looks first:With the spinach that boiled water scald crosses, the content of oxalic acid decreased, the content of water-solubility vitamin also decreased, the mouthfeel of Dan Bo dish is better however.
Before spinach makes food, use need not boiled water Xian Chao is dropped, be because of the person different, proposal exceeding elder brother everybody, the spinach that passes with boiled water scald does not want excessive cook, prevent to boil spinach leaf sodden.
[spinach of boiled water scald, either those who do not have a truth]
The metropolis before a lot of people do spinach uses boiled water Xian Chao, but do not know why to want certainly so do. Will tell from mouthfeel, the spinach that trashy Shui Chao crosses tastes more acerbity, and the spinach mouthfeel that passes with Shui Chao is better; From the point of the angle that exceeds elder brother, this is oxalic acid actually in do mischief.
Oxalic acid, formal name second 2 acid, yi Rong at water, there are a few presences in a lot of food, in a few food content is very high. And the spinach that we should say today, it is a kind of food with oxalic acid faster content, the spinach of every 100 grams contains 618 milligram [the oxalic acid of 1] .
Research makes clear [2] , iron below 100 ℃ float 2 minutes, the purify rate of the oxalic acid in spinach is 45.7% . The method that so people often says to use spinach of boiled water scald is really OK scald drops one part oxalic acid.
And scald drops the oxalic acid in spinach, besides improvement mouthfeel, still can reduce the absorb and affects calcium absorption of oxalic acid.
Oxalic acid counteracts the calcic ionic union of free in small intestine fluid commonly, generate oxalic acid calcium to crystallize, outside final eduction body; Only the oxalic acid of one part is absorbed in small intestine blood, with blood medium calcic ionic union forms oxalic acid calcium, after in the kidney the juice that follow make water is concentrated, solubility precipitates more possibly than inferior oxalic acid calcium come down, and bring about uric road stone [3] .
Nevertheless everybody need not worry too, come besides spinach, other food also more or less contain oxalic acid, we are impossible to avoid completely; Metabolization of 2 bearer body also can have oxalic acid to arise, also can metabolize go out.
But exceed elder brother or should remind, the person that already had uric road stone or have the chronic enteron disease, person that has done excision of paragraphs of big small intestine, the absorptivity of oxalic acid often meets prep above ordinary person, so, with boiled water scald spinach eats again very be necessary.
[spinach of boiled water scald, water dissolve vitamin is met loss]
A lot of person place say no less than, the spinach that passes with boiled water scald decreased besides oxalic acid, the vitamin also decreased subsequently.
Research makes clear [4] :
B1 makes an appointment with vitamin of the spinach after Shui Chao loss 27.3% , vitamin B2 makes an appointment with a loss 18.8% , vitamin C makes an appointment with a loss 66.4% .
Can see, water scald spinach can cause the loss of water-solubility vitamin really, especially the loss of vitamin C. If the other nutrition material in Dan Bo dish is K of carotene, lutein, vitamin, prandial fiber won't cause remarkable loss because of scald water.
But cook means does not have perfect, for the person of more to suiting to absorb oxalic acid, it is good to use boiled water scald to have spinach again first; And the person that hopes to obtain a vitamin from inside spinach, can complement through cooperating other to feed capable person.
[sum up]
Spinach of boiled water scald, had had also have bad. With the spinach that boiled water scald crosses, the content of oxalic acid decreased, the content of water-solubility vitamin also decreased, the mouthfeel of Dan Bo dish is better however.
Before spinach makes food, use need not boiled water Xian Chao is dropped, be because of the person different, proposal exceeding elder brother everybody, the spinach that passes with boiled water scald does not want excessive cook, prevent to boil spinach leaf sodden.
The welcome pays close attention to " word exceeding elder brother is fed " , more and healthy little knowledge understands during the Spring Festival oh!
