In each place of a pig, the price of pigskin is low, but also do not lack the person that likes to eat pigskin, pigskin often also appears on our table.
So what nutrition does pigskin have? Does the nutrient value of pigskin have many tall?
Exceed elder brother to chat with everybody with respect to the nutrient value of pigskin today.
The answer looks first:The nutrient value of pigskin basically comes from protein, other nutrition value is not high.
[the structure of pigskin]
Pigskin altogether has 3 structures, it is cuticular layer, dermal layer, hypodermic connective tissue respectively form.
The collagen albumen that everybody pays close attention to is with collagen albumen fiber the form exists in dermal layer, 99% what take dry matter.
[the nutrient composition in pigskin]
Protein, adipose, water basically is contained in pigskin. Among them the collagen albumen in protein most suffer everybody to pay close attention to.
Somebody is grown to flourish prosperous pig sample undertakes detecting, every 100 pigskin that overcome delicacy contain protein to make an appointment with 25.6 grams, total protein content is 25.68% ± 0.42, it is porky 2.5 times, crude fat content is 25.47% ± 0.24, moisture content is 48.03% ± 0.38, ash content content is 0.64% ± 0.15, among them collagen protein content occupies total protein content to be 74.12% ± 0.99[1] .
Content of each index in the pigskin of different breed has difference, but difference is not big. Collagen protein content exceeds 70% basically.
[the nutrient value of pigskin]
The nutrient value of pigskin basically comes from the nutrient composition of pigskin. This shows, the nutrient value of pigskin basically comes from protein and among them collagen albumen.
Biology considers to discover:
Collagen protein and the faculty that join water are concerned, inside human body if lack this kind to belong to biology macromolecule glue kind collagen albumen of material, can make the mechanism of water of keep in storage of the cell inside body produces an obstacle. The cell combines water quantity to decrease apparently, human body can happen " dehydration " phenomenon, make the skin gently dry, take off bits, lose flexibility, furrow be overflowing with, affect life again.
But the collagen albumen in pigskin eats into body inside, through digestion digestive meeting turns into amino acid, pigskin eats euqally in can not resembling hearsay albumen of can direct compensatory collagen.
But one of raw material that the certain and amino acid after decomposing is albumen of collagen of human body synthesis, say to eat pigskin to have nutrient value so, but if eating, also have nothing to do with, human body has automatic rehabilitate function, the amino acid that supplies in other edibles also can produce similar action.
[sum up]
Think value of nutrition of a kind of alimental, want to see its nutrient part, people basically pays close attention to 7 kinds of big nutriment, if satisfy human body need, the food of OK and compensatory nutrition, have nutrient value.
Without perfect food, because this people needs to obtain nutrient value from inside different food, why do this recommend balanced diet namely. The outstanding nutrient composition in pigskin is protein, it is OK to eat pigskin accordingly better land complement is protein, content of other nutrition composition is very small, cannot have big effect.
More food knowledge by " word exceeding elder brother is fed " will solve, the welcome pays close attention to a comment!
