Basil (Ocimum basilicum L. var. thyrsiflora) seed was analyzed for its physico-chemical, phytochemical, functional, and hydration properties. The seed is ellipsoid in shape with mean dimensions of 2.52 mm length, 1.43 mm width and 1.10 mm thickness. Thousand seed weight was 2.10 g. Hunter color values (‘L’, ‘a’ and ‘b’) of basil seed were 14.24, 0.42, and 47.85, respectively which depicts black colour of seeds. Proximate composition showed that the seed contain 8.90 % moisture, 9.40 % protein, 33.01 % fats, 5.20 % ash, 43.50 % carbohydrates and 36.30 % total fibre. Gas chromatographic-mass spectrometric analysis showed the presence of omega fatty acids such as alpha-linolenic acid (71.10 %), palmitic-acid (13.72 %), stearic-acid (8.26 %), oleic-acid (1.53 %), arachidioic-acid (1.17 %) and traces of gamma tocopherol, gamma linolenic-acid, and squalene. The phytochemical analysis of seed showed the presence of 18.24 mg GAE/g phenolic compounds, 0.525 mg QE/g flavonoids, 15.64 mg/g alkaloids, 0.97 mg/g saponins, and 0.134 mg/g triterpenoids. An antioxidant activity of 30.30 % was observed. Furthermore, higher values for water absorption capacity (37.72 g/g) and lower values for oil absorption capacity (6.04 g/g) were observed. Besides, low values for syneresis (7.37 %) and a high emulsification capacity (95.50 %) was obtained. Hydration studies indicated that the presence of ions decreased the water absorption and swelling power of basil seed. Scanning electron microscopy depicted an oblong shape and a smooth surface of basil seed. Findings suggest that basil seed can be used as a promising ingredient in food industry.

罗勒(Ocimum basilicum L.)种子的理化特性

对罗勒(Ocimum basilicum L. var。thyrsiflora)种子的理化,植物化学,功能和水合特性进行了分析。种子为椭圆形,平均尺寸为长2.52毫米,宽1.43毫米,厚1.10毫米。千粒重为2.10克。猎人颜色值(“ L”,“ a ”和“ b”罗勒种子的')分别为14.24、0.42和47.85,其描绘了种子的黑色。最接近的组成表明,种子含有8.90%的水分,9.40%的蛋白质,33.01%的脂肪,5.20%的灰分,43.50%的碳水化合物和36.30%的总纤维。气相色谱-质谱分析表明存在欧米茄脂肪酸,例如α-亚麻酸(71.10%),棕榈酸(13.72%),硬脂酸(8.26%),油酸(1.53%),花生二酸酸(1.17%)和痕量的γ-生育酚,γ-亚麻酸和角鲨烯。种子的植物化学分析表明,存在18.24 mg GAE / g酚类化合物,0.525 mg QE / g黄酮类化合物,15.64 mg / g生物碱,0.97 mg / g皂苷和0.134 mg / g三萜类化合物。观察到抗氧化剂活性为30.30%。此外,更高的吸水量值(37。观察到72 g / g)和较低的吸油量值(6.04 g / g)。此外,获得低的脱水收缩值(7.37%)和高的乳化能力(95.50%)。水合研究表明,离子的存在降低了罗勒种子的吸水率和溶胀力。扫描电子显微镜描绘了罗勒种子的椭圆形和光滑表面。研究结果表明,罗勒种子可以在食品工业中用作有前途的成分。
