Abstract

HighlightsThe extraction of black pepper oleoresin was investigated by varying particle size and solid-to-solvent ratio.The oleoresin extraction yield and piperine content were improved by decreasing particle size of pepper powder.An increase of solid-to-solvent ratio from 1:5 to 1:10 resulted in the greater oleoresin extraction yield.Suitable particle size and solid-to-solvent ratio for extraction are below 0.125 mm and 1:10, respectively. Abstract. Black pepper oleoresin is extensively applied as a natural flavoring ingredient in the food industry. It contains piperine which has various benefits for human health. However, limited research has been conducted on black pepper oleoresin extraction, especially regarding the influence of key parameters on the yield and quality of the oleoresin product. Therefore, this research determined the effect of particle size and the solid-to-solvent ratio on the yield and quality of black pepper oleoresin extracted using the soxtec method. Four different particle sizes and four solid-to-solvent ratios were evaluated using ethanol as the solvent. The moisture content of black pepper powder, the oleoresin yield, the piperine content and the volatile oil and non-volatile oil contents were determined. The moisture content of the black pepper powder was 12.5% whereas the oleoresin and volatile oil contents of black pepper were 16.2% d.b. and 3.9% d.b., respectively. Both the yield and piperine content of oleoresin significantly increased with decreasing particle size from 0.5 to <1 mm to smaller than 0.125 mm. A decrease in the solid-to-solvent ratio from 1:5 to 1:10 significantly increased the oleoresin yield; however, a ratio lower than 1:10 did not provide any significant increase in the oleoresin yield. Decreasing the solid-to-solvent ratio led to a significant increase in the piperine content of oleoresin only when the ratio decreased from 1:5 to 1:20. There were no significant effects of particle size or the solid-to-solvent ratio on the volatile oil and non-volatile oil contents in the oleoresin. A suitable particle size and solid-to-solvent ratio were below 0.125 mm and 1:10, respectively, regarding increased yield and piperine content in the oleoresin. These results have contributed to a better understanding of the key factors affecting the yield and piperine content of black pepper oleoresin and of the conditions suitable for black pepper oleoresin extraction which can be utilized in the food and pharmaceutical industries.

粒度和固液比对黑胡椒油树脂提取物得率、胡椒碱含量、挥发性和非挥发性含量的影响
研究了不同粒径和料液比条件下黑胡椒油树脂的提取工艺。减小辣椒粉粒度可提高油树脂提取率和胡椒碱含量。料液比由1:5提高到1:10,油树脂提取率提高。适宜的萃取粒度为0.125 mm以下,料液比为1:10以下。摘要黑胡椒油树脂作为一种天然调味品在食品工业中得到了广泛的应用。它含有胡椒碱,对人体健康有各种好处。然而,对黑胡椒油树脂提取工艺的研究较少,特别是对关键参数对油树脂产品得率和质量的影响研究较少。因此,本研究确定了粒径和料液比对soxtec法提取黑胡椒油树脂得率和质量的影响。以乙醇为溶剂,考察了四种不同的粒径和四种固液比。测定了黑胡椒粉的水分含量、油树脂得率、胡椒碱含量、挥发油和非挥发油含量。黑胡椒粉的水分含量为12.5%,油树脂和挥发油的含量分别为16.2%和3.9%。从0.5 ~ <1 mm到小于0.125 mm,油树脂的得率和胡椒碱含量随粒径的减小而显著增加。料液比由1:5降至1:10,油树脂收率显著提高;然而,低于1:10的比例并没有显著提高油树脂收率。当料液比从1:5降低到1:20时,油树脂中胡椒碱含量才会显著增加。颗粒大小和料液比对油树脂中挥发油和非挥发油含量无显著影响。提高油树脂收率和胡椒碱含量的最佳粒径为0.125 mm以下,料液比为1:10以下。这些结果有助于更好地了解影响黑胡椒油树脂得率和胡椒碱含量的关键因素,以及黑胡椒油树脂提取的适宜条件,可用于食品和制药工业。关键词:黑胡椒油树脂,粒径,胡椒碱,固溶比,Soxtec法
