The Processing Principle Of Eucommia Ulmoides And The Development Of Instant Tea Of Eucommia Male Flowers

Eucommia ulmoides Oliv. is a kind of Angiospermae Dicotyledoneae Eucommiaceae plant, and it is a very precious Chinese herbal medicine in China. As early as 2000 years ago, our country has been Eucommia as an important medicinal plant incomed <Shennong bencaojing>. Since 1980, a large number of domestic and foreign study found that Eucommia body is of important value. Its bark, leaves, fruit containing Eucommia rubber are the most important resource except Hevea Rubber. It not only can be used as medicine, but also can be used as health food, functional food and feed additive with tonifying the liver and kidney, strong bones and muscles, lowering blood pressure, reducing blood lipid, anti fatigue, anti osteoporosis, anti cell toxicity and protect liver function. Eucommia has broad application prospects for people, and the development of new products is becoming more and more necessary.The main results of this study:Researched Eucommia geniposidic acid, chlorogenic acid, geniposidic, pinoresinol diglucoside, ferulic aldehydes, pinoresinol content changes at different processing temperatures. Broken wire in Chinese Pharmacopoeia was seen as the standard, and the salt Eucommia Eucommia samples were prepared in electric oven at different temperatures. RP-HPLC method was used for the content determination of geniposidic acid, chlorogenic acid, geniposidic, pinoresinol diglucoside, ferulaldehyde, pinoresinol. Chromatographic conditions: Thermo Hypersil Gold C18 column(5 ?m, 250 mm × 4.6 mm); acetonitrile as mobile phase A, 0.1% phosphoric acid water as the mobile phase B, gradient elution(0 min, A:B=8:92; 10 min, A:B=15:85; 35 min, A:B=17:83;50 min, A:B=23:77;70 min, A:B=33:67). Flow rate: 1.0mL/min; detection wavelength: 230 nm; Injection volume: 10 ?L. Column temperature:25?. Results: Eucommia processing temperature should be controlled at 180~190?, and at this temperature geniposidic acid, chlorogenic acid, geniposidic alcohol and pinoresinol diglucoside decreased, and content of ferulaldehyde and pinoresinol rose higher.Second, analysis the appropriate process parameters of ultrasonic extraction and flash extraction method in industrial production. process flow: Eucommia ulmoides Male flower, cleaning, extracting, filtering, concentrating the filtrate, spray drying, finished product and packaging. Results: the most important factors to influence on the two kinds of extraction methods of single factor investigation. The tea powder yield as evaluation index, combined with the industrial cost finally, suitable process parameters of ultrasonic method for industrial production of instant tea of Eucommia male flowers in 200 w is the power of ultrasonic extraction two times, ultrasonic time of 45 min, the first material to liquid ratio of 1:15(g/mL), second times the ratio of solid to liquid 1:6, its soup is yellow green and bright, rich and refreshing, unique aroma lasting, instant tea powder of Eucommia male flowers was 25.6%; the appropriate process parameters of flash extraction method for industrialized production of Eucommia male flowers of instant tea is two times of flash under 6 min, the first material to liquid ratio was 1:10,second times the solid-liquid ratio was 1:8, the soup color is soft Huang Mingliang, mellow taste, fragrant lasting, instant tea powder of Eucommia male flowers was 28.3%.Third, this paper also analyzes the concentration process influence on yield and quality of instant tea powder, concentrated by rotary evaporation and flash condensation type two kind of different concentration process influence on yield and quality of instant tea powder. The results show that: the flash sensory evaluation of instant tea powder concentration of high concentrated by rotary evaporation process and the rate of tea powder has no obvious difference.Fourth, Research the quality standard of the instant tea of Eucommia ulmoides Male Flowers and formulate quality standard draft. Established with chlorogenic acid as control TLC method for the determination of product, to determine the moisture content and the main component of chlorogenic acid.
