dc.description.abstract | The cactus pear (Opuntia ficus indica) mucilage is an interesting ingredient for the food industry
because of its viscosity properties. We studied the conditions for the extraction and precipitation of
the plants mucilage. Extraction conditions were: pad/water ratios (1:51:7), extraction temperature,
(4072 and 1672 1C) and extraction time (4, 8 and 16 h). For the precipitation of the mucilage two
types of alcohol (ethanol and isopropyl alcohol) and two water/alcohol ratios (1:3 and 1:4) were
used.
No differences were found in any of the measured variables among the different extraction or
precipitation methods.
The average mucilage yield after drying was 1.48% based on fresh weight (f.w.) and 19.4% based
on dry weight (d.w.).
The dried mucilage had in average 5.6% moisture; 7.3% protein; 37.3% ash; 1.14% nitrogen;
9.86% calcium and 1.55% of potassium. The colour analysis showed a high L* value and the
chromatic co-ordinates were in the yellow-greenish spectrum.
The use of isopropyl alcohol is recommended in ratio 1:3, since its commercial value is lower in
comparison with ethanol. | |
