      Abstract
      Minyak kedelai berpotensi sebagai komoditas industri karena mengandung asam lemak tak jenuh. Bacillus subtilis dan B. licheniformis dapat mengolah minyak kedelai menjadi produk bernilai tambah melalui fermentasi yang memanfaatkan aktivitas enzim lipase. Ulasan ini menganalisis perubahan metabolit setelah fermentasi minyak kedelai oleh dua bakteri selama 14 hari. Analisis menggunakan gas kromatografi-detektor ionisasi nyala menunjukkan peningkatan pada asam oleat (C18H34O2) dan linoleat (C18H32O2), serta munculnya asam lemak baru, yaitu asam kaproat (C6H12O2), asam miristat (C14H16O2), asam palmitoleat (C16H30O2), asam heptadekanoat (C17H34O2), dan asam lignoserat (C24H48O2). Gas kromatografi-spektrometri massa menujukkan komponen yang diduga menghasilkan aroma terhadap hasil fermentasi adalah metil oleat (C19H36O2). Fermentasi berhasil mengubah metabolit dan memberikan nilai tambah pada minyak kedelai.
       
      Soybean oil has high potential as an industrial commodity due to its unsaturated fatty acid content. Bacillus subtilis and B. licheniformis can process soybean oil into value-added products through fermentation utilizing lipase enzyme activity. This review analyzes the metabolite changes during the 14 days of soybean oil fermentation by these two bacteria. Analysis using a gas chromatography-flame ionization detector showed an increase in oleic acid (C18H34O2) and linoleic acid (C18H32O2), as well as the appearance of new fatty acids, namely caproic acid (C6H12O2), myristic acid (C14H16O2), palmitoleic acid (C16H30O2), heptadecanoic acid (C17H34O2), and lignoceric acid (C24H48O2). Gas chromatography-mass spectrometry indicated that the component likely responsible for the aroma of the fermentation product is methyl oleate (C19H36O2). Fermentation successfully demonstrated metabolite changes and added value to soybean oil.
