Abstract
Since there is limited knowledge about trans fat levels in snack foods available in Pakistan. This study aimed to determine trans fat content in fried vermicelli (a common snack food). It is prepared in partially hydrogenated oil (ghee), which is the main cause of trans fat formation. Twenty-one fried vermicelli samples were collected from different local shops of Hyderabad, Pakistan and subjected to oil extraction by using Soxhlet method. Partial least square regression model was developed to quantify trans fats in fried vermicelli using FTIR spectroscopy. Total oil content in fried vermicelli ranged between 17.28- 32.99%. FTIR results revealed that fried vermicelli showed trans fats in between 7.3-20.9% in extracted oil, whereas total trans fat in food was ranged at 1.3-5.9%. The FTIR data of trans fat was compared with GC-MS data and found comparable results (pandgt;0.05). Presence of high trans fat in fried vermicelli is an alarming issue for the health of consumers.
