Abstract
Cactus pear (Opuntia ficus-indica) seed is one of the main components of fruit crops which are
tightly packed together in a mucilaginous structure inside the endocarp of the fruit. Nutritional
composition, anti-nutritional factors, anti-oxidant activities, functional properties and sensory
attributes of cactus pear seeds collected from Hatest kebele Hawzen Woreda, Eastern Zone of
Tigray region were determined. The moisture, crude protein, crude fat, crude fiber, total ash,
carbohydrate and gross energy contents of cactus pear seed averaged as 4.17g/100g, 10g/100g,
10.50g/100g, 18.23g/100g, 1.63g/100g, 55.47g/100g and 392.84cal in dry weight basis,
respectively. The dietary Ca, K, P, Fe, and Zn content of the sample accounted 390.14mg/100g,
446.46mg/100g, 206.18mg/100g, 4.37mg/100g, and 2.01mg/100g, respectively. High phytate
content (259.20mg/100g) and low contents of tannin (0.13mg/100g) and oxalate (0.11mg/100g)
were obtained. The presence of high content of total phenols and total flavoniods in the sample
produce an appreciable amount of anti-oxidant capacity which ranged from 43 to 95% of
inhibition. When the functional properties of cactus pear seed flour was compared with each
other, high value of water solubility index (5.6g/100g) and low value of bulk density (0.80g/ml) in fresh weight basis were obtained. The sensory evaluation of cactus pear seed revealed that
consumption of ‘Ambasha’ (traditional bread) formulated with wheat flour was more preferable
up to the ratio of 85:15% (wheat/seed) and the aroma of all sample ratios was highly attractive
than the other sensory attributes. The overall acceptability of the bread showed that there was no
significant differences (p 0.05) among the samples prepared in wheat to cactus pear seed flour
ratios of 100:0%, 95:5% and 90:10%, but these were differed significantly (p 0.05) from the
remaining sample fractions (85:15%, 80:20% and 75:25 %). In conclusion, the present study
demonstrated that cactus pear seeds can be used as food supplementation in arid and semi-arid
areas.
