Food is made up of many different chemical can components or parts, including vitamins, minerals, sugars, fibres, water, lipids, proteins and starches.

In addition to these main nutrient components, many foods contain smaller amounts of biologically active chemicals. In plants, these are referred to as phytochemicals. Scientists can separate out all of these different components of foods.

Why separate food into its component parts?

There are many reasons why scientists might want to separate out the component parts of food. For example, the nutrigenomics project investigated why different people respond differently to different foods. It seems that sometimes these variations arise because of differences in our genes. This is because our genes can affect the way that our bodies deal with the chemical components that make up a particular food. As a result, some food can components might be particularly good for some people, and cause problems for others!

The aim of the nutrigenomics project is to work out which specific food compounds are most helpful (or most harmful) to people with particular food-related diseases, like Crohn’s disease.

How can different food components be separated?

Because different molecules have different chemical properties, they are more or less able to adsorb (or stick) to materials such as silica gel. This means that they can be separated based on their polarity (degree of surface charge). For example, hydrocarbons (molecules with lots of carbon and hydrogen atoms) have no affinity for silica, whereas alcohols have strong affinity.

How is the use of easy peel-off end in food packaging?

The Easy peel off ends(lids), is a metal packaging form with high sealing and certain pressure resistance,is used in food canned packaging. The base material is made of tinplate or aluminum,after punching, drawing and curling, it can be safely opened after opening.

The demand of the market has also led to the development of various types of production equipment. From material suppliers to CNC press machines, peel off end making machine, visual inspection machine, stamping box machine, filling and sealing machine, etc., complete supply chain has been formed and technology is more mature.

Under the development trend of food safety and environmental protection, the material suppliers and the peel off end making machine are technically difficult. At present, Amcor Limited Company and China's one named Huzhou Jinjie Industry Co., Ltd. Is supplier of coating materials. Peel off end making machine, the previous technology is in the hands of SOUDRONIC AG in Switzerland,.Now, Hangzhou Sunking machinery Co., Ltd. Since 2006, after years of hard work, independent research and development, has mastered the technology of peel off end making machine and become a famous Chinese company in international metal packaging industry.

Metal pails and drums are two storage containers that are similar in function, but vary in capacity and the pail drum components used to make them. Notice that pails hold only 7 gallons or less, while steel drums can hold far more. Also, the higher the gauge size of the material, the thinner it is. Pails are made up of 22-24 gauge metal while steel drums are composed of 20 gauge and under making them stronger. Pails typically have bails or handles attached to them for ease of carrying while drums do not.
