The paste made of cocoa beans through cleaning, screening, baking, hulling, alkalization (or non-alkalization) and fine grinding is called cocoa liquid block, also known as cocoa or bitter substances. Cocoa liquid block has the characteristics of fluid in a warm state and solidifies into a block after cooling, so it is called a liquid block. Cocoa liquid is an important raw material for producing chocolate. Cocoa butter and cocoa cake can be obtained by pressing cocoa liquor, and cocoa cake is an essential raw material for processing various cocoa powders.

The preparation method of margarine is as follows: firstly, liquid grease and solid grease (hydrogenated grease) are sent into a blending tank according to the formula requirements, and then salt, sugar, seasoning, edible pigment, milk powder, emulsifier, preservative and water are blended into an aqueous solution. Adding while stirring, so that the aqueous solution and the oil form emulsion. Then quickly cooled and kneaded by a cooler, and then packaged into finished products.

The main component of margarine is trans fatty acid. Although trans fatty acids can make food taste better, trans fatty acids do great harm to human health, but they have not attracted people's attention. In fact, when the structure of fatty acids changes, their properties will also change. Many people know that safflower oil, corn oil and cottonseed oil containing polyunsaturated fatty acids can reduce the cholesterol level in human blood, but when they are hydrogenated into trans fatty acids, the effect is just the opposite. Trans fatty acids can increase LDL (low density lipoprotein cholesterol, which can increase the risk of coronary heart disease) and decrease HDL (high density lipoprotein cholesterol, which can reduce the risk of coronary heart disease), thus increasing the risk of coronary heart disease. A number of studies on the harm of trans fatty acids jointly carried out by eight European countries show that trans fatty acids have a great responsibility for the occurrence and development of cardiovascular diseases. It is 3-5 times more likely to cause cardiovascular diseases than saturated fatty acids, and even damages people's cognitive function. In addition, trans fatty acids can also induce tumors (breast cancer, etc. ), asthma, type 2 diabetes, allergies and other diseases increase the probability of female infertility by more than 70%, which also has adverse effects on fetal weight and adolescent development.

The two are not the same thing, but they are generally found in chocolate. Cocoa liquid is harmless to people and won't get fat.
