Abstract:
To manufacture beef tallow (BT)‐based shortening and margarine with a reduced tendency to developing sandiness, BT/canola oil (CaO) blend (80:20 w/w), selected from the BT and CaO blends mixed in different ratios from 60:40 to 85:15 with 5% increments, was subjected to chemical interesterification (CIE) with sodium methoxide as the catalyst. The interesterified products were compared with the starting mixture in terms of solid fat content (SFC), and contents of high‐melting point 1,3‐disaturated long‐chain fatty acid 2‐monounsaturated long‐chain fatty acid triacylglycerols (SUS TAGs) including 1,3‐distearoyl‐2‐oleoyl‐glycerol (StOSt), 1,3‐dipalmitoy‐2‐oleoyl‐glycerol (POP), and 1‐palmitoyl‐2‐oleoyl‐3‐stearoyl‐glycerol (POSt). Under the selected conditions: 60 °C, 0.6% CH 3 ONa, 90 min, the CIE product had a SFC profile that meets suggested bakery fat requirements, besides a content of SUS TAGs which is 22.14% lower than that of the non‐interesterified blend. Also the fat produced had stable β′ polymorphs, crystal morphology, crystal sizes ( 〈 20 μm), and could resist temperature fluctuations. The CIE product obtained herein has an increased potential for manufacturing bakery shortenings and margarines with reduced graininess formation, increasing the possibilities for the commercial use of BT and CaO.
