摘要
An interesterified structured lipid was produced with a lipid mixture (600 g) of pine nut oil (PN) and palm stearin (PS) at two weight ratios (PN:PS 40:60 and 30:70) using lipase (Lipozyme TL IM, 30 wt.%) as a catalyst at 65 degrees C for 24 h. Major fatty acids in the interesterified products were palmitic (35.1-40.4%), oleic (29.5%), and pinolenic acid (cis-5, cis-9. cis-12 183; 4.2-5.9%). alpha-Tocopherol (1.1-1.3 mg/100 g) and gamma-tocopherol (0.3-0.4 mg/100 g) were detected in the interesterified products. Total phytosterols (campesterol, stigmasterol, and p-sitosterol) in the interesterified products (PN:PS 40:60 and 30:70) were 63.2 and 49.6 mg/100 g, respectively. Solid fat contents at 25 degrees C were 23.6% (PN:PS 40:60) and 36.2% (PN:PS 30:70). Mostly beta' crystal form was found in the interesterified products. Zero-trans margarine fat stock with desirable properties could be successfully produced from pine nut oil and palm stearin. (C) 2009 Elsevier Ltd. All rights reserved.
