Study On The Extraction Technology Of Rhizoma Zingiberis And The Product Development Of Honey Ginger Tea With Sugar

With the constant deepening of research on Ginger resources,ginger extract as natural food raw materials have been widely used in food,which not only can maximize the use of ginger’s nutrition and health care function,but also can give food unique flavor of ginger.This paper aims to study the the main components of rhizoma zingiberis from different areas and to compare them,while the ethanol rhizoma zingiberis was studied,and to make honey ginger tea by mixing the honey and ginger extracts,which provide research foundation for deep processing of ginger.The main results are as follows:1 The principal component study of different origin stem gingerSelected fourteen different places of ginger slices as raw material,studying their quality by testing the physical and chemical indicators including moisture,6-gingerol,8-gingerol,6-shogaol,and 10-gingerol.The results showed that the highest total ginger phenol content ginger slice is from Wenshan County,Yunnan Province,14.211mg/g,the lowest total ginger phenol content ginger slice is from from Juxian County,Shandong Province,8.705mg/g.At the same time to test the content of phenolic compounds from the ginger residue of funan dry ginger extract,and discover the total gingerol extraction rate of ginger slice in Funan County,Anhui Province can reach 88.7%,it also further validation the extraction process of dry ginger.2 Study on the extraction technology of rhizoma zingiberisUsing Funan County,Anhui Province ginger slices as raw material,To detect the ginger extracts of ginger polyphenols content by HPLC method.On the basis of signal-factor test,to chose the fact of ethanol concentration(%),extraction temperature(℃),solid-liquid ratio,extraction time(h),and using phenolic compounds of ginger extracts as evaluation index,the optimization of the machining technology provided by orthogonal test of ethanol leaching of rhizoma zingiberis.The results showed that the optimum extraction process of rhizoma zingiberis is: the rhizoma zingiberis crushed through 60 mesh,the extraction temperature is 50℃,the ethanol concentration is 80%,the solid-liquid ratio is 1:10,the extraction time is 2h.The four facts ranked in the following order :extraction temperature,solid-liquid ratio,extraction time,ethanol concentration.3 The research on production technology of honey ginger tea with sugarUsing ginger extract,honey and sugar as main raw materials,which are mixed evenly,then through the rotation of the granulation to get honey ginger tea with sugar.On the basis of signal-factor test,taking sensory indicators as the assessing index,the chose the fact of ginger extract addition(%),sugar powder mesh(mesh),honey addition(%)and water addition(%),and using the way of central composite experiment,the best formula of honey ginger tea with sugar was found out,which was:with sugar(brown sugar: sugar powder =7:3)100 g,glucose powder 6 g,ginger extracts 2.3%,sugar powder mesh 60,Honey added 1.5%,water 1%.The four facts ranked in the following order : ginger extract addition,water addition,honey addition,sugar powder mesh.The honey ginger tea with sugar under optimal process,which particle size was uniform,the color was red and bright,had obvious taste of spicy ginger and honey,the ginger aroma and honey fragrance coordination soft.
