Lipid characterization of black soybean ( Glycine max [L.] Merrill ) seeds using GC‐MS / HS fingerprinting

Abstract

The present study was to characterize the lipid profile of five black soybean (BS) produced in Indo‐Himalayan regions. Among seven fatty acids (FAs), methyl linoleate and cis‐9‐oleic acid methyl ester were maximum. Unsaturated/saturated fatty acid ratio was highest (6.10%) in BSALB (big spherical shape seed). Unsaponifiable matters and tocopherols were also higher (3.09% and 1305 μg/kg, respectively) in BSALB, while β‐carotene was improved in BSALS (small oval‐shaped seed). Flavor analysis reported 46 compounds in the oil, which were maximum in BSALS. There was significant difference (p < 0.02) in the flavor components. Crop cycle temperature is inversely correlated with major lipid constituents. The results suggest that the BS seeds produced comparatively in high‐altitude regions retain the maximum lipid antioxidants and flavor compounds. Presence of these phytoconstituents may be explored to utilize black soybean in flavor and nutraceutical industries to boost the application of this underutilized crop.

A systematic review of black soybean (Glycine max (L.) Merr.): Nutritional composition, bioactive compounds, health benefits, and processing to application

“…Particularly, C18:2 (ω−6 family of polyunsaturated fatty acids) and C18:3 (ω−3 family of polyunsaturated fatty acids) are known for their potential benefits for cardiovascular and brain health (Chatterjee et al., 2018). Currently, the supercritical fluid extraction of BS oil has gained wide attention because of its potential to significantly reduce the risk of phytochemical degradation (A. Kumar et al., 2022). Moreover, fully understanding the lipid characteristics using gas chromatography‐mass spectrometry technology will enhance the potential utilization of BS in different food, flavor, and nutraceutical industries.…”

Lipid Composition Analysis and Characterization of Acyl Sterol Glycosides in Adzuki and Soybean Cultivars by Non-Targeted LC-MS

“…Soybean (Glycine max (L.)) is generally considered an oil seed and is gaining attention because it is rich in various natural antioxidants, including β-carotene and tocopherols, and has high protein content [11,12]. China and Japan are the largest importing countries of beans and its products [13].…”
