Hawthorn (Crataegus spp.) fruit: Some physical and chemical properties
Scopus
Toplam 115 atıf DOI
The hawthorn (Crataegus spp.) fruits were analysed for some physical (dimensions, geometric mean diameter, sphericity, bulk density, fruit density, volume, terminal velocity, hardness and porosity) and chemical (moisture, crude protein, crude oil, crude energy, crude fiber, ash, pH, acidity, water- and alcohol soluble extract) properties. Mineral content of wild hawthorn growing in Turkey were determined by Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES). All materials contained high amounts of Ca, K, Mg, Na and P. These values were found as 3046.37 ppm, 13,531.96 ppm, 1502.55 ppm, 312.18 ppm, 1477.88 ppm and 431,307.29 ppm, respectively. The mean pulp and seeds weight, length, diameter, mass, volume, geometric mean diameter, sphericity and projected area were measured as 2.16 g, 0.87 g, 14.39 mm, 19.34 mm, 3.03 g, 3083.3 mm3, 17.52 mm, 1.22 and 4.19 cm2, respectively. The energy, protein, cellulose, oil, ash, acidity and water-soluble extract values of hawthorn fruits were established as 34.02 kcal/g, 2.48%, 4.67%, 0.87%, 2.28%, 1.98% and 32.31%, respectively. It is very important to evaluate the physical properties for the design of equipment used for harvesting, transportation, storage and processing of fresh fruits. Also, the information supplied on the chemical properties of the hawthorn fruit can be used in human nutrition. © 2004 Elsevier Ltd. All rights reserved.

Biochemical and technological properties were determined in developing Myrtus communis L. fruits (myrtle) from Mersin to investigate potential uses. Completely ripe black and white fruits contained ash, crude protein, crude oil, water- and alcohol soluble extracts, tartaric, malic and citric acids, and minerals including Ca, K, P, Mg and Na. Proximate compounds (%) for black and white fruits were: 7.47 and 6.36 protein, 3.487 and 3.453 oil, 3.02 and 2.30 ash, 24.28 and 26.09 dry matter, respectively. Fruits were found to be rich in some minerals such as Ca (6719.88 mg/kg and 4676.14 mg/kg), K (22647.78 mg/kg and 18339.84 mg/kg), Mg (2145.19 mg/kg and 1408.88 mg/kg), Na (3336.16 mg/kg and 2976.59 mg/kg) and P (4336.07 mg/kg and 3927.4 mg/kg). Also, physical properties such as length (14.94 mm and 13.64 mm), mass (0.94 g and 0.94 g), geometric mean diameter (12.73 mm and 12.31 mm), sphericity (0.85 and 0.90), diameter (11.76 and 11.70), projected area (1.48 cm2 and 1.65 cm 2), kernel density (757.47 kg/m 3and 752.09 kg/m 3), porosity (41.41% and 39.05%), bulk density (426.50 kg/m 3 and 431.05 kg/m 3), terminal velocity (8.42 m/s and 8.49 m/s), volume (1.32 mm 3 and 1.35 mm 3), repture strenth (1.77 N and 2.06 N), static (0.26-0.33 and 0.20-0.28) and dynamic coefficient (0.22-0.29 and 0.17-0.24) of friction of black myrtle and white myrtle fruits species were measured at 75.72% and 73.91% moisture content levels, respectively. These results show that both myrtle fruits may be useful for the evaluation of dietary information in important food crops. © 2011 Association of Food Scientists & Technologists (India).
