Eggs, also known as chicken eggs and chickens, are eggs produced by hens. It has a hard shell outside, inside there is a gas chamber, egg white and yolk portion. Rich in cholesterol, nutritious, an egg weighing about 50 grams, containing 7 grams of protein. Egg protein amino acid ratio is very suitable for human physiological needs, easy for the body to absorb, the utilization rate of up to 98%, high nutritional value, is one of the food that humans often eat.

Some people care about its color when picking eggs. Older generations like to buy red skin eggs and think that it is better nutrition than white skin eggs. But now online there are rumors that "the white skin eggs are more nutritious, because the white shell is the eggs of the earth, the red shell is the foreign eggs, the white skin eggs are fed the corn and other food, the eggs fed by the feed chickens It is red, so the white skin is more nutritious." So, is the color of the eggshell deep or light?

For the "white shell is the soil eggs" point of view, food development engineer Fu Yangyu said that the eggshell color comes from the eggs in the hen's reproductive tract in the final processing process - the secretion of pigment in the uterus epithelium evenly coated on a white background On the eggshell, what pigment is specifically secreted depends first on the hen's genotype. Among commercial hens, white shell hens are mainly bred from the ancestors of "White Leghorn Chicken", and brown broiler hens are mainly cultivated from "Royal Island Red". Powder shell layer chickens are a combination of white shell layer chickens and brown shell layers. Therefore, the color of the eggshell alone cannot determine whether it is produced by free-range, stocked chickens or by commercial chickens raised on large-scale feeds.

As for the white skin egg nutrition or the red skin egg nutrition, from the egg formation process, the eggshell is formed in the last process. Before the eggshell color is formed, the material in the egg is formed. Therefore, the color of the eggshell does not directly affect the nutritional content of the egg. Therefore, after selecting the eggs, it is no longer necessary to distinguish them by the color of the shells.

Key Intermediates

Intermediate – Intermediate: A material produced during a drug substance processing step that must undergo further molecular modification or refinement to become a drug substance. Intermediates may or may not be isolated. Intermediates are the key products of the previous process of making APIs, which are different in structure from APIs.

Ceftriaxone sodium powder is called preparation, sterile ceftriaxone sodium is called API, and 7-ACA is called intermediate.

Our company specializes in providing key intermediates for various APIs

Intermediate is a very important type of fine chemical products. Its essence is a type of "semi-finished product", which is an intermediate product in the production of certain products. For example, if a product is to be produced, it can be produced from intermediates, saving costs and reducing It is widely used in the synthesis of medicines, pesticides, coatings, dyes and spices. In the field of medicine, intermediates are an important link in the industrial chain of the pharmaceutical industry. They are used for some chemical raw materials or chemical products in the process of drug synthesis. In a word, they are used to produce APIs.
