In the fields of modern food and biotechnology, subcritical extraction technology is gradually becoming a universal, environmentally friendly and efficient extraction method. This article will discuss the application of subcritical extraction technology in chicken bones, beef bones, pig bones and other materials, including the process and advantages of extracting oil and protein.
Subcritical extraction is an extraction technique in which a solvent is operated above its boiling point but below its critical point. Compared with traditional solvent extraction methods, subcritical extraction has the characteristics of low temperature, low pressure and high efficiency. For raw materials rich in oil and protein such as chicken bones, beef bones, and pigs, subcritical extraction can effectively extract useful ingredients.
First, let us understand the process of subcritical extraction for oil extraction. After crushing chicken bones, beef bones, pig bones and other raw materials, put them into subcritical extraction equipment. Under appropriate temperature and pressure, use appropriate solvents (such as propane, butane, etc.) for extraction. The solvent comes into contact with the fat in the bone, dissolving it and bringing it out. After separation and refining, high-quality bone oil can be obtained.
The advantage of this oil extraction method is that it can retain the nutrients in the raw materials to the greatest extent while avoiding the impact of high-temperature processing on the quality of the oil. The extracted bone oil can be used in food processing, cosmetics manufacturing and other fields, and has broad application prospects.
At the same time, the proteins in chicken bones, beef bones, and pig bones obtained after subcritical extraction have high purity and biological activity, and can be used in food supplements, feed additives and other fields.
Compared with traditional extraction methods, subcritical extraction technology has multiple advantages. It can be performed at lower temperatures, reducing damage to heat-sensitive components. At the same time, the choice of solvent is more environmentally friendly and reduces environmental pollution. In addition, subcritical extraction technology also has the characteristics of fast extraction speed and high efficiency, and can achieve large-scale industrial production.
The application of subcritical extraction technology in chicken bones, beef bones, pig bones and other fields has demonstrated its huge potential in extracting oil and protein. This technology not only provides new development opportunities for the food and biotechnology industries, but also contributes to the comprehensive utilization of resources and sustainable development. With the in-depth research and application promotion of this technology, it is believed that subcritical extraction will play an important role in more fields and bring more benefits to people's lives.
