摘要
研究确定新鲜番茄皮渣在热风干燥箱中最适干燥条件:厚度1.0 cm,温度100℃,时间160 min;然后采用碱性提取法从番茄皮渣中提取水溶性膳食纤维,通过单因素试验和正交试验确定最佳提取工艺条件:料液比1︰17、pH值12、提取温度85℃、提取时间120 min,此时提取率最高,达36%;水溶性膳食纤维的膨胀性和持水力分别为5.9 mL/g,9.85 g/g。
The fresh tomato pomace was studyed by drying in hot air and determined the optimum conditions： the thickness of 1.0 cm,temperature 100 ℃,time 160 min;Through single factor experiments and orthogonal experiment,alkaline extraction method was used to extract the soluble dietary fiber from tomato pomace and the optimum extraction conditions was that： the ratio of liquid was 1：17;pH value of was 12 and extraction 120 min at 85 ℃.The extraction rate was up to 36% at this time.soluble dietary fiber swelling was 5.9 mL/g and water holding capacity was 9.85 g/g.
