甜椒紅色素的提取及性質(zhì)的研究 |
| 吳永蘭(湖南安淳高新技術(shù)有限公司; 湖南長(cháng)沙) |
| 摘 要：將粒度為0.150 mm的廣東、湖南等地產(chǎn)的紅甜椒干粉進(jìn)行辣椒紅色素的提取試驗。研究得出:將濃度為95%的AR級乙醇以1:16 g/ml的料液配比在50 ℃下提取3 h為提取辣椒紅素的優(yōu)化條件。過(guò)濾濃縮后所得紅棕色油狀辣椒紅色素的 ASTA值≥1000,汞含量≤0.01 mg/kg,為油溶性食用天然紅色素。該色素在弱酸性至弱堿性范圍內穩定,熱穩定性也好,但耐強光性較差,若將色素溶解在油脂中則其光穩定性增強。此提取工藝因省去了除辣工序而變得簡(jiǎn)便。甜椒紅色素屬于β-胡蘿卜素類(lèi)物質(zhì),既有天然色素的作用,又兼有維生素之營(yíng)養強化劑的功效。 |

| WU Yong-lan（Hunan Anchun Advanced Technology Co.; LTD; Changsha 410015; China） |
| Abstract：The extraction of natural red pigment from different kinds of peppers of Guangdong province and Hunan province was researched. The results showed that sweet pepper from Guangdong province is the best candidate for extraction and the best extracting conditions are as follows: alcohol solution (95%) as menstruum, the ratio of powder and menstruum at 1:16g/ml and at the temperature of 50 ℃ for 3 h. The condensed umber oily product has high ASTA value ( ≥1000) and Hg (mercury) element lower than 0.01 mg/kg. The... |
