Solution Overview

Problem

Existing fat compositions for solid roux struggle to balance shape-retaining properties in summer, resistance against liquid oil seepage, surface whitening, and good melting speed in the mouth while reducing trans fatty acid and saturated fatty acid content.

Innovation Solution

A fat composition with a triglyceride composition including 15 to 40% S3, 10 to 30% S2U, 10 to 25% SU2, and 30 to 50% U3 triglycerides, with specific fatty acid ratios and content limits to achieve desired physical properties and reduced saturated and trans fatty acid levels.
