  • During the 2009 global economic downturn, the dairy industry was also affected. Global milk production had gradually decreased, and the dairy industry was failing. However, in 2010, China's sudden consumption increase of dairy products, the price of dairy products recovered due to the great demand in China. The Asian continent as a whole played a significant role in maintaining the health of the global dairy industry, by preventing its total collapse. Currently, the price of all dairy products, except that of whole milk powder, has increased. The International Dairy Federation (IDF) expects that milk production will grow by 2% annually over the next 10 years, owing to Asia's high demand for all kinds of dairy products.

  • This study was investigated on antioxidant activities of water, methanol and ether extracts of clove. The extraction yields of water, methanol and ether extracts were 34.7, 21.4 and 17.0%, respectively. Total phenolic contents of water, methanol and ether extracts were 23.1, 55.7 and 34.9%, respectively. Eugenol contents were 6.1 and 8.1% in methanol and ether extracts, but it was not detected in water extract. Electron donating abilities of water, methanol and ether extract were 36.1, 30.9 and 29.7%, respectively. In linoleic aicd system, the ether extract showed more high antioxidant activity than water and methanol extracts. The antioxidant activity of ether extract was almost equal that of $\alpha$-tocopherol, but weaker than that of BHT In linoleic acid emulsion system, the water extract showed higher or stronger antioxidant activity than methanol and ether extracts. Antioxidant activities in linoleic acid emulsion substrates were in order of BHT ＞water extract＞methanol extract＞ether extract＞ $\alpha$-tocopherol.
