摘要
为对红枣膳食纤维进行超微粉碎,以D50为指标,研究超微粉碎工艺参数对膳食纤维粉碎粒度的影响。在单因素的基础上采用响应面法优化膳食纤维的超微粉碎工艺。结果表明:粉碎时间10.53 min、填充量303.54 g/L、物料水分含量4.95%时,具有较好的粉碎粒度,在此条件下得到的最小D50为16.57μm。采用超微粉碎工艺,可有效降低红枣膳食纤维粒度。
In order to ultra-fine grind the jujube dietary fiber,the effect of ultra-fine grind parameters on grain size of dietary fiber were studied using D_(50) as index.Based on signal factor test,the response surface methodology was used to optimization the technology.The results shown as follows:The D_(50) was16.57 urn at grinding time 10.53 min,loading level 303.54 g/L and water content of material 4.95% .It can decrease grain size with ultra-fine grind efficiently.
