Research status of extruded breakfast cereals

Research status of extruded breakfast cereals
As early as in the Yellow Emperor's Internal Classic Su Question, the principle of "five grains for nourishment, five fruits for help, five livestock for benefit, five vegetables for full" was put forward, which explained the dominant position of grain in diet. Breakfast cereal is a kind of breakfast food which is processed with corn, wheat, rice, oats and other cereals as the main raw materials.
There are two main ways to process breakfast cereals. One is the extrusion and expansion technology of microwave drying machinery and equipment, the other is the production of steam roller dryer. Extrusion technology of microwave drying machinery and equipment has many advantages, such as low production cost, high efficiency, wide applicability of raw materials, good product quality and low loss of nutrients, so it has been widely used in cereal breakfast food processing.
1 Research Progress on breakfast cereals
1.1 research progress of grain breakfast processing machinery abroad
Breakfast cereals originated in the United States. It was first patented by Dr. Kellogg for cereal manufacturing and founded Kellogg's Food Company. After that, cereal breakfast foods flourished around the world.
At present, cereal breakfast has been greatly developed in Europe and America, and has gained a high market position. In Asia, cereal breakfast consumption is very small, but in Korea, Singapore, Japan and other countries, cereal breakfast market has also developed rapidly. At present, the world's major producers of breakfast cereals include Australian Sundrim Company, Nestle and General Mill Food Company of the United States. The main brand of Nestle is breakfast cereals, such as crispy grain and nutritious cereal.
1.2 domestic breakfast research progress
Domestic research on cereal breakfast started late, and has gradually become a new research hotspot in recent years. Wang Liang of Food College of Jiangnan University studied the effects of various factors on texture characteristics of breakfast cereals, including extruder temperature, screw speed, feed moisture, starch content, protein content and fat content. Wu Weiguo, School of Food Science and Technology, Hunan Agricultural University, developed a cereal breakfast food based on three kinds of cereals by using twin-screw continuous extrusion cooking technology. Wen Xinhua of Hunan Business College determined the basic formula of cereal breakfast according to the nutritional composition and sensory index of raw materials, discussed the extrusion process conditions, and formed the complete technology of industrialized production of cereal breakfast food.

Application of Camellia Seed Oil in Cosmetics Industry

图片
Before the advent of modern cosmetics, camellia seed oil was used as a traditional skin care hair care product in East Asia to improve the moisturization, smoothness and elasticity of skin and hair. Camellia saponin contained in camellia seed oil is a non-toxic surfactant with antioxidant activity and can be applied to advanced washing products. Compared with traditional surfactants, tea saponin has the advantages of being degradable, non-polluting and non-toxic, and is a natural active agent. Camellia seed oil can also be used to make cleansing oil with a very mild effect. Microwave drying machine Cosmetic grade camellia seed oil is mainly produced by low temperature and high pressure process. It is often used as a high-end cosmetic raw material or as a massage base oil, and is widely welcomed in domestic and foreign markets. Application of Camellia Seed Oil in Cosmetics Industry

Research on Hydraulic Pump Control Technology

1 blade control technology The high-pressure energy-saving hydraulic vane pump controls the vane through the electric signal and the pilot hydraulic oil, and uses the solenoid valve to control the pilot oil to pass through the rear distribution disc, leads to the outside of the propeller shaft, and finally flows into the vane pump rotor, the pump shaft, and the vane locking mechanism.  hydraulic vane pump   The pilot hydraulic oil acts on the slide valve to press a small steel ball into the concave surface of the blade. The blade is completely locked in the blade groove of the rotor, and the sealing volume cannot be formed between the blade, the stator, the rotor and the oil distribution plate, and the blade card The pump is idling, thus stopping the vane pump oil supply cycle, reducing the drive or engine output power, and saving energy. The high pressure energy-saving vane pump is stuck in the rotor when the system does not require flow and pressure. When ...

Microwave vacuum drying of banana slices

图片
The microwave vacuum drying equipment technology was used to develop new banana drying products, and the optimum microwave vacuum drying technology for banana slices was obtained. microwave vacuum drying   The effects of vacuum, microwave intensity and slice thickness on color difference, brittleness, swelling rate and sensory quality of banana slices were studied by three factors and three levels L9 (34) orthogonal design. The technological parameters of microwave vacuum drying of banana slices were optimized by comprehensive optimization method. The quality of dried banana slices obtained by different microwave vacuum drying process parameters is obviously different. The optimum point of microwave vacuum drying process is determined as follows: vacuum degree - 80 kPa, microwave intensity 14 W/g, slice thickness 12 mm. The quality of dried banana slices obtained under this process condition is better than that of microwave drying. And vacuum frying. It is fea...
