There are many manufacturing methods that have been done. As a pectin supplier, we will introduce to you today one of the methods of manufacture apple pectin for blackberry jam-the microwave method.
The methods of manufacture apple pectin for blackberry jam-the microwave method
Microwave is an electromagnetic wave with a frequency ranging from 300MHz to 300GHz. The corresponding wavelength is 1mm to 1m, which is longer than the wavelength of visible light, and belongs to electromagnetic waves in the high-frequency band. Microwave has the wave characteristics of electromagnetic wave reflection, transmission, interference, diffraction, polarization, and energy transmission accompanied by electromagnetic waves. Microwave method also has high frequency characteristics, thermal characteristics and non-thermal characteristics. People mainly use it in communications, radio and television and other fields.
Since the 1960s, people have gradually applied microwave heating technology to physical processing processes. Such as paper, wood, and resin extrusion. In recent years, microwave method has been introduced in the process of chemical reactions. Not only can effectively improve the reaction conversion rate and selectivity, but also reflect many advantages such as energy saving and environmental protection. As one of the means to realize green chemical industry, it has widely value by people. At the beginning of the 21st century, the United States issued a patent for extracting pectin using microwave heating technology.
Compared with traditional methods, microwave extraction can greatly accelerate the hydrolysis of tissues. And it shorten the extraction time of pectin from 90 minutes to 5 minutes by traditional methods. Moreover, the heating is uniform and will not damage the long chain structure of pectin. At the same time, energy consumption is reduce, process operation is easy to control, and labor intensity is reduce. The quality of the obtained sample is good. The gel performance, color, solubility and other indexes all improve, and the yield increase by 2% compared with the traditional method. In addition, it also saves a lot of alcohol solvents, and the product quality meets the national quality standards. Therefore, microwave method has important practical significance in production and application. At the same time, the application of microwave heating technology in the chemical and food fields has attracted more and more attention.
