Hc360 HC Network Food Industry Channel Vegetable oil and animal oil can be identified from the following six aspects:
(1) Different forms: at room temperature, animal oils such as lard, tallow and sheep oil are mostly solid, while vegetable oils such as vegetable oil, soybean oil and peanut oil are mostly liquid.
(2) Different melting points: animal oil has a high melting point and vegetable oil has a low melting point.
(3) Different absorption rate: Generally speaking, the closer the oil with low melting point is to body temperature, the higher the absorption rate, which can reach 97% ~ 98%. Once the melting point of oil exceeds 50℃, it is difficult for human body to absorb it. The more it is absorbed, the greater its health effect will be.
(4) Different fatty acids, animal oil contains more saturated fatty acids and vegetable oil contains more unsaturated fatty acids. Saturated fatty acids have a high melting point, and are easier to coagulate and precipitate on the blood vessel wall than unsaturated fatty acids at the same temperature, which is the main cause of human arteriosclerosis. Unsaturated fatty acids mainly include linoleic acid, linolenic acid and arachidonic acid, which are indispensable nutrients for human metabolism and are essential to the health of skin and hair. If a person has sufficient supply of unsaturated fatty acids, then his skin must be moist and smooth, and his hair will be black and shiny. On the contrary, he has rough skin, easy peeling and brittle hair.
(5) Different cholesterol content: animal oil contains more cholesterol, while vegetable oil basically contains no cholesterol. High cholesterol in blood is the cause of atherosclerosis, obesity, diabetes and other diseases. Soybean sterol and sitosterol contained in vegetable oil can not only be absorbed by human body, but also prevent the absorption of cholesterol, which is the biggest advantage of vegetable oil. Ergosterol contained in vegetable oil is a precursor of vitamin D, which can be converted into vitamin D by ultraviolet irradiation.
(6) Different kinds of vitamins are absorbed: Fat is the solvent of fat-soluble vitamins, and fat-soluble vitamins can be absorbed only if food contains enough fat. There are four kinds of fat-soluble vitamins, namely vitamin A, vitamin D, vitamin E and vitamin K. Animal oil can absorb vitamin A and vitamin D, and vegetable oil can absorb vitamin E and vitamin K. Vitamin A and vitamin D are nutrients needed for human growth and development, and vitamin E and vitamin K are nutrients needed for blood and reproductive system in human body.
From the comparison of the properties of the above two oils, vegetable oil has high nutritional value and contains many components beneficial to human health. Eating less animal oil and more vegetable oil can make people grow up healthily and prolong life.
Haha, my understanding is that peanut oil is better.
Here are some practices, I hope you will like them.
1. Milk yellow bag
Ingredients: eagle millet flour 300g milk powder 200g custard powder 100g egg liquid 1000g sugar 1000g light milk 1 tin coconut milk 1 tin condensed milk 1 tin butter 600g.
Method:
1. Put corn starch, milk powder, custard powder, egg liquid, white sugar, evaporated milk, coconut milk and condensed milk into a mixing barrel, stir at a medium speed, and then add 2000 grams of water and stir into a thin paste.
2. Wash the pan, put it on the fire, add water to boil, put the mixing barrel into the boiling water pot, stir the thin paste in the barrel continuously with an egg beater until it becomes a little thick, then pour it into the pot, add butter, steam it in a cage for about 30 minutes, take it out and stir it evenly with an egg beater, and finally put it in the cage for about 20 minutes, then take it out and let it cool.
When making cream yellow stuffing, you should control the amount of water, and don't add too much, otherwise the cream yellow stuffing will be very thin, which is not conducive to packaging.
Milk yellow stuffing is often used to make all kinds of sweet snacks, and milk yellow buns are the most famous varieties (milk yellow buns are made of fermented flour wrapped with milk yellow stuffing).
Self-raising flour is recommended for flour. If those raw materials are too troublesome, you can use egg liquid, butter, whole milk powder and powdered sugar instead.
2. Crystal cream bag
Cream filling materials: egg 1 piece, 20g dry powder, 2 teaspoons of custard powder, 45ml milk, 50g sugar and 20g butter.
Manufacture of milk yellow stuffing
Butter first. 2. Add sugar in three times and stir well. 3. Add the eggs and mix well. Finally, add milk powder and custard powder. 4. Steam the prepared batter every 65,438+00 minutes, and it will feel solidified next to it. Be sure to mix well. 5. Stir while steaming for about 6.30 minutes.
The material of the crystal skin is 70g dry powder, 20g raw powder, 1ml salt = 1/4 teaspoons.
manufacturing process
Sieve the materials and stir them evenly. There is no water to add at this time. Light flour, 150ml water is heated by microwave and boiled quickly. Add hot water slowly and stir quickly. Because the weather is hot, stir it with chopsticks first to ensure uniform mixing. Let the hot water burn all the flour, and your hands will gradually adapt to the heat. Knead into dough and add 1/2 tbsp salad oil. Cut into10g. 8. This amount can be made into 15 parts, and the milk pit is also divided into 15 parts. Roll it into a leather bag, make the bottom of the closed surface, put it into a mold, press out the patterned paper (without mold preservation), put it into oil, put it into the center, steam it after the boiler is boiled, and then reduce the heat for 3 minutes.
I am addicted to looking for pictures, but I still like to eat hair noodles.
My very best wishes to your health
