法桐果毛纤维的结构及吸油性能

Structure and Oil Absorption Property of Platanus Fruit Fiber

探究法桐果毛纤维的吸油性能。观察了法桐果毛纤维的结构形态,分析了吸油时间、油温以及法桐果毛纤维质量对纤维吸油倍率的影响。结果表明:法桐果毛纤维纵向光滑,有类似竹节状的凸起,横截面呈圆形或椭圆形,有中空结构;用于吸附食用油的最优工艺为吸油时间10min,油温25℃,纤维质量0.10g,纤维对食用油的吸油倍率达32.1g/g;用离心法除油后进行循环吸油,循环5次后,吸油倍率从原来的32.1g/g降到了30.0g/g,仅下降了6.5%。认为:法桐果毛纤维具有较好的吸油性能,离心法可以实现法桐果毛纤维的循环吸油。

The oil absorption property of platanus fruit fiber was studied. The structural morphology of pla- tanus fruit fiber was observed. The influences of oil absorption time,oil temperature and platanus fruit fiber quan- tity on fiber oil absorption rate were analyzed. The test results show that the platanus fruit fiber was smooth in longitudinal with bamboo joint. The cross section was round or oval with hollow structure. The optimized process for edible oil absorption is 10 min absorbing time,25 ℃ oil temperature and 0.10 g for fiber weight. The oil ab- sorption rate of fiber for edible oil is up to 32.1 g/g. The cyclical oil absorption is performed after removing oil with centrifugation method. After five cycles,the oil absorption rate was decreased from original 32.1 g/g to 30. 0 g/g. There is only 6.5 % decrease. It is considered that platanus fruit fiber has better oil absorption. The cyclical oil absorption can be achieved with centrifugation method.
