    摘要:本文以人參加工廠的廢棄人參渣作為實驗原料,采用雙螺桿擠壓膨化來改性并優化人參渣可溶性膳食纖維(SDF)的最優條件為:溫度140℃,轉速130r/min,含水量40%。在此條件下,SDF的提取率為34.5%。采用正交試驗將人參水溶性膳食纖維(SDF)與輔料混合制備,通過調整配料的比例關系,制成口感佳,外觀好的膳食纖維飲料。通過實驗確定了最佳飲料配方為:按照重量份數計,將8 份山梨糖醇、0.2 份檸檬酸、0.25 份羥甲基纖維素鈉(CMC)、0.25 份果膠、0.04 份維生素C和100 份可溶性膳食纖維和蒸餾水混合,得到混合物,混合物中SDF的最終濃度為6mg/mL。在此條件下制成的人參膳食纖維飲料口感與外觀最佳。

    Abstract: In this paper,waste ginseng residue from ginseng processing plant was used as experimental raw material.The optimal conditions of modification and optimization of soluble dietary fiber(SDF)of ginseng residue by twinscrewextrusion were as follows: temperature 140℃,rotational speed 130r/min,and water content 40%.Under theseconditions,the extraction rate of SDF was 34.5%.The water- soluble dietary fiber and excipients of ginseng weremixed and prepared by orthogonal experiment. By adjusting the proportion of ingredients,the dietary fiber beveragewith good taste and good appearance was made. The optimal drink formula was determined by experiments asfollows: 8 parts sorbitol,0.2 part citric acid,0.25 part sodium hydroxymethyl cellulose(CMC),0.25 part pectin,0.04 part vitamin C and 100 parts soluble dietary fiber and distilled water were mixed according to the weight,andthe final concentration of SDF in the mixture was 6mg/mL. The ginseng dietary fiber beverage made under theseconditions has the best taste and appearance.

    Key words: ginseng;twin screw extrusion puffing;oluble dietary fiber;beverage
