The study investigated the profile of fatty acids (FA) in grape seed (GS) and grape seed oil (GSO) of a newly developed teinturier grape variety, named Manjari Medika (MM). FAs were identified and quantified by gas chromatography with flame ionisation detection. The identification of FAs was further confirmed using a GC with mass selective detector (GC-MS). The profiles of MM-GS and MM-GSO were compared with the corresponding products of two established varieties, viz. Cabernet Sauvignon (CS) and Sauvignon Blanc (SB). The unique FA profile of MM was differentiated from CS and SB through multivariate statistical analysis and pattern recognition of selective FAs. MM-GSO was found to be superior to SB-GSO and equivalent to CS-GSO in terms of FA profile. The presence of unsaturated FAs at a higher level and a favourable ratio of essential FAs (omega-6: omega-3) indicated the potential health benefits of MM- GS and GSO. The FA levels in MM-GSO were within or above the Codex standards for edible oil. The typical FA profile uniquely differentiated these three varieties of seeds and corresponding oils. The results formed the basis of a future endeavor in establishing their varietal authenticity.

该研究调查了一种新开发的teinturier葡萄品种Manjari Medika（MM）的葡萄籽（GS）和葡萄籽油（GSO）中的脂肪酸（FA）概况。通过气相色谱和火焰离子化检测对FA进行鉴定和定量。使用具有质量选择检测器的GC（GC-MS）进一步确认了FA的鉴定。将MM-GS和MM-GSO的谱与两个已建立品种的对应产品进行比较，即。赤霞珠（CS）和长相思（SB）。MM的独特FA轮廓通过多元统计分析和选择性FA的模式识别与CS和SB区别开来。在FA轮廓方面，发现MM-GSO优于SB-GSO并等同于CS-GSO。较高水平的不饱和脂肪酸的存在和必需脂肪酸（omega-6：omega-3）的有利比例表明MM-GS和GSO具有潜在的健康益处。MM-GSO中的FA含量在食用油法典标准之内或以上。典型的FA谱独特地区分了这三种种子和相应的油。这些结果构成了未来确定其品种真实性的基础。
