AbstractFor the past 20 years, consumers have been reducing their saturated fat consumption due to health concerns surrounding animal high fat diets. This trend has affected several food products. Dairy products, in particular butter, have been considered to increase the risk for cardiovascular diseases in humans because, in comparison to other lipid sources, they contain a high proportion of cholesterol. Studies describing the association between dairy food consumption and the risk of cardiovascular disease (CVD) have been inconsistent. In large epidemiological studies, consumption of high cholesterol fat dairy products has been associated with an increased CVD risk, while intake of low cholesterol fat dairy foods has not. The aim of the present study was to evaluate the use of ß-CD with pasteurized whole milk in an industrial process after churning the cream for making low cholesterol butter with the purpose of manufacturing commercial reduced cholesterol butter. Fatty acid and chemical gross composition (total fat, lactose, protein and total solids) of the untreated and 0.6% ß-cyclodextrin (ß-CD) treated butter were determined. Gas chromatography of the individual fatty acids methyl esters (saturated, monounsaturated and polyunsaturated) were not significantly affected by the use of ß-CD. Cholesterol reduction of the commercial butter was 95.53 ± 2.81% with a residual content of ß-CD of 0.04 ± 0.01% and the ß-CD cholesterol complex removed in the butter-serum during the churning of the cream and in the washing process. This developed procedure provide a considerable reduction of cholesterol in butter without altering the fatty acids composition of the milk fat.
