Physicochemical Analysis of Margarine, Butter and Butter Oil Samples of Iran’s Markets
نویسندگان
چکیده مقاله:
Butter, margarine and butter oil are three products which consume daily by Iranian’scommunity. Detection of type and existence of synthetic antioxidants (SAs) quantities in the margarine, butter and butter oil samples is so important in point of view of the safety. For this purpose, peroxide value (PV), oxidative stability (OS), iodine value (IV), fatty acid analysis (FA), type and amount of SAs, and its antioxidant activity (AA%) of the samples was determined as described methods of the International Organization for Standardization (ISO) documents including ISO numbers: 3960, 6886, 3961, 5509, AOCS Ce 6-86, and DPPH assay, respectively. The direct relationship between the quantities of OS, SA and AA% was observed in the samples. It was observed that many of butter oil samples were without SA. In margarine samples, the amount of IV was higher than that of in butter and butter oil samples (P

Butter, margarine and serum lipoproteins.
Intake of trans fatty acids unfavorably affects blood lipoproteins. As margarines are a major source of trans, claims for the advantages of margarines over butter need to be scrutinized. Here we review dietary trials that directly compared the effects of butter and margarine on blood lipids. We identified 20 studies in which subjects had stable body weights, and margarine and butter were exchan...
متن کاملComparison of Physicochemical Characteristics of Margarine and Butter in Iranian Market During Storage
Margarine contains a higher level of unsaturated and trans-fatty acids (TFA) than butter. The aim of this study was to investigate the physicochemical properties of these products in Iranian market during storage. Physicochemical analyses included fatty acid composition, peroxide and Anisidine values, slip melting point (SMP), color, chlorophyll content, solid fat content (SFC) and texture an...
متن کاملdetection of margarine in butter
milk fat is frequently adulterated to meet the demand which exceeds the supply and to increase profit margins. samples of butter adulterated with different levels (5, 10 and 15% w/w) of margarine were prepared and analysed using different methods including refractive index, iodine, reichert-meissl and polenske values. gc and hplc were utilized to determine fatty acid and tocol profiles of sampl...
متن کاملEffect of butter, mono- and polyunsaturated fatty acid-enriched butter, trans fatty acid margarine, and zero trans fatty acid margarine on serum lipids and lipoproteins in healthy men.
The effect of diets containing 50% of fat calories from butter, butter enriched with mono- and polyunsaturated fatty acids, and margarines with and without trans fatty acids on the serum lipids of 38 healthy men in a free-living condition have been determined. Serum lipid responses to the high level of individual dietary fats were unexpectedly small. The butter diet produced a small, but signif...
متن کاملShea Butter: An Opposite Replacement for Trans Fat in Margarine
Shea butter is the edible fat extracted from the nut of African Shea tree (Vitellaria paradoxa). Consequence of having half of its fatty acids saturated, Shea butter melts at a very high temperature and will be a suitable raw material for margarine production. Margarine is a butter mimicry that is produced from vegetable oils and water. The production of margarine requires a solid fat. Hence hy...
