Physical and Mechanical Properties of Three Varieties of Mango

Abstract

Physical properties of three varieties of mango were studied at 13.75% and 8.74% moisture content levels. Some selected properties such as geometric mean, arithmetic mean, angle of repose, sphericity and crushing force were determined. The average tri-axial dimensions of the seeds gave 38.00 ± 6.8, 42.23 ± 4.12, 33.95 ± 6.91 as average major diameter; 35.60 ± 5.68, 39.18 ± 3.95, 31.44 ± 7.56 as average intermediate diameter and 24.76 ± 5.2, 28.42 ± 5.59, 23.08 ± 3.67 as average minor diameter for Kerosene, Sheri and Sugar mango respectively. The average sphericity of the three varieties of mango seed was 0.74, 0.77 and 0.67 while that of the angle of repose was 40.430, 08.030 and 09.760 for Kerosene, Sheri and Sugar mango respectively. The average crushing force determined using the universal testing machine gave 21.00 N, 10.58 N and 9.46 N for Kerosene, Sheri and Sugar mango respectively. Statistical analysis shows that there is a significant difference in the geometric mean between Kerosene mango and Sheri mango and no significant difference between Sheri mango and Sugar mango, while the average value of the calculated arithmetic mean was found to be statistically different within the three varieties but no significant difference in sphericity. Kerosene mango has the highest value for the angle of repose and crushing force.

Fruit Characteristics, Peel Nutritional Compositions, and Their Relationships with Mango Peel Pectin Quality

“…The geometric mean diameter represents the central tendency of the primary dimension and is normally used as parameter when designing fruit sorting machines [52,53]. Our result showed that the D g values were greater than reported by Osadare et al [54]. The arithmetic mean diameter (D a ) is also an important indicator in determining the quality attribute of a particular mango variety according to size and maturity stage [55].…”
