Konjac flower

[Guest guest]

Hi All,

Konjac flour may be improved, it seems, by extensive grinding. Better weight

management may have been due shown to be due to reduced calorie intake, if the

full-text had been available. The better blood sugar and triglyceride levels

are

good also, although the reduced level of high density lipoproteins was not

beneficial.

For a useful source for konjac information, including the flour, there is:

A good introduction to konjac for the not pdf-available below paper may be:

Grain-Size Effect on the Structure and Antiobesity Activity of Konjac Flour

Bin Li, Jun Xia, Yang Wang, and Bijun Xie

Abstract:

The effect of high-frequency oscillatory type ball-mill treatment on the

structure

and antiobesity activity of konjac flour was investigated. The grain size of

konjac

flour changed from 657.3 m (d50) to 23.7 m (d50) after 4 h of treatment. The

structural change of the konjac flour with different grain size was

characterized by

using X-ray diffraction (XRD) differential scanning calorimetry (DSC). The

results

indicated that the crystallinity decreased and the diffraction peak drifted not

only

by when the crystallization region was reduced but also when the crystalline

structure was changed. With the decrease of the grain size and crystallinity,

the

konjac flour grain, especially the 4 h milled konjac flour, swelled more rapidly

and

led to the improvement of the antiobesity effect. Compared with the native

konjac

flour, the 4 h milled konjac flour could significantly decrease the body weight

and

total wet weight of fat of nutritional obese rats (P < 0.05) and also decreased

the

contents of triglyceride, glucose, and high-density lipoprotein in blood of

nutritional obese rat significantly (P < 0.05), which meant the grain-size

effect of

konjac flour improved its antiobesity activity notably.
