The Quality And Safety Of Dry Red Wine Imported From Rizhao Harbor

As the development of economy and the improvement of human well-being in China,consumers have the higher requirements for wine’s tasty and function of health care.The consumption of wine is in an ascendant status in China.Wine industry in China started relatively later than the other countries,so the quality of wine is not good enough to feed consumers’ requirements.Therefore,the imported wine from other countries,which was favored by the consumers have the opportunity to participate in Chinese market.However,the quality and safety of the wine,the efficient way to inspect the quality and guide the importation of wine correctly need to be solved in urgent.This project tested and analyzed the qualities of dry red wines imported from Rizhao harbor from 2013 to 2015 by quality indicators including the content of dry extract,alcohol level,volatile acid,iron,copper and lead,and the residues of sulfur dioxide,benzoic acid and sorbic acid,and microbial food safety.The results were supposed to provide the basis for the government department to perform an efficient testing regulation.The main results of the research are reported as follows:(1)The quality of dry red wine from Rizhao harbor was good,all the indicators evolving the content of alcohol,dry extract content,volatile acid,were able to meet the requirements of Chinese National Standards.(2)The residue of sulfur dioxide,antiseptic(benzoic acid and sorbic acid),heavy metal(iron,copper and lead)in dry red wine from Rizhao harbor between year 2013,2014 and 2015 were able to meet the requirements of Chinese National Standards.The detection rate of antiseptic was increasing,and residue of benzoic acid were significant difference between years in dry red wines(P< 0.05),and the content of copper significantly increased(P< 0.05).So the government inspectors in Rizhao harbor should monitor the food safety of imported wine strictly.(3)The microbial safety of wine from Rizhao harbor was good,able to meet the requirements of Chinese National Standards.(4)The France product of dry red wine from Rizhao harbor 2015,benzoic acid,sorbic acid and copper content detection rate is higher,the Australian product copper content detection rate is higher,should focus on.
