Abstract

Background: Consumption of trans fatty acids (TFAs) is a major risk factor of cardiovascular diseases. In Iran, similar to other countries in the world, food manufacturers seek to minimize the amount of this compound in food. The current study aimed to modify wafer cream formulations by mixing hydrogenated oil (HO), canola oil (CO), and texturizers in order to achieve optimum physicochemical and texture properties with a minimum of TFAs. Methods: In the present study, 11 samples of wafer cream were prepared using a different percentages of HO and CO, as well as starch and carboxy methyl cellulose (CMC) as texturizing agents. Changes in formulation were compared using a two-way analysis of variance (ANOVA) performed in SPSS21 with a 95% confidence level. Findings: The obtained results indicated that with the increasing rate of HO replacement with CO, the moisture was constant. Compared with control sample, the anisidin value was reduced as well as acidity, peroxide and TBA increased, whereas the stifness of texture decreased. Moreover, it was observed that TFAs and saturated fatty acid amount decreased, while the amount of mono-and polyunsaturated acids increased. Nonetheless, no significant difference was observed in the kind of texturizing agents and examined properties. Conclusion: The most optimal formulation was obtained by replacing 20% HO with CO and achieving 1% of TFAs. Accordingly, this formulation is recommended to be used by industrially food manufacturers in the production of wafer cream. © 2019 Journal of Health System Research.
