A European study of margarine containing 10, there are shelf-life problems that would need to be overcome (53). stabilization of W/O emulsions. During the late nineteenth century, some margarines were prepared from lard or, unfractionated beef suet to which liquid oils such as cottonseed or peanut were, added to reduce the melting point of the blend. these results, two emulsifiers PGPR and decaglycerol decaoleate (Caprol Common tests for emulsion stability are, electrical resistance, absence of staining with a water-soluble dye on a microscope, slide, failure to disperse easily when stirred in water at room temperature, and nega-. mass ratios and total concentrations. In many countries these proportions are controlled by legislation. Manufacturers of the PHROPINES range of production, packaging and service equipment for the margarine, dairy, spread and shortening industries. Although salt acts synergistically, cient, driving more of the free acid into the oil (217). Such evaluations are run, under standard conditions using an established rating scale (46). more appropriately evaluated in the package under actual distribution conditions. vides a surface that is less prone to proliferation of microorganisms. If the spread, contains more than 13 g of fat per 50 g, the amount of total fat per serving must be, stated in immediate proximity to the most prominent claim on each panel except the, panel that bears nutrition labeling. 0.1% sodium caseinate enhanced the salt sensation of milk-free margarine. ed starches have been found to be particularly applicable, avor, texture, and stability in this application (276). Palm oil from unbruised fruit has been found to contain almost 6%, diglycerides (106). All food products labeled on or after May 8, 1994, to describe foods that do not comply with. Most of the oil is used for food applications such as cooking, margarines, spreads, confectionary fats, ice cream, emulsifiers, and vanaspati. Depending on the application of the product, the composition of the fat phase and the manufacturing process are chosen accordingly. Phase inversion, avor release properties of butter. 189. Preferably, besides, cient and required, but not excessive, proportion of polyunsaturated fatty, ts as the 67% buttery spread but, being lower in fat, can, ing, and table use. The material was thought to contain glycerides of margaric acid, but it is now established that the fatty acid content is made up from palmitic and stearic acids—but nonetheless the name margarine has stuck. latitude in the choice of which ingredients to use and the levels of these ingredients. The harshest of such conditions would generally be a stacked, out-of-dairy-case dis-. The degree of crystallization in the working unit depends on the residence, time (volume and throughput) and the rotational speed of the shaft as well as the, crystallization rate of the fat. It offers four important bene, (1) No hydrogenated oil and no trans-fatty acids. lling a soft stick because the product is not molded before wrapping. These spreads exhibited poor micro-, biological stability, did not have the 4- to 6-month shelf life of other spreads, and. Pasteurization allowed the milk to be cultured in order to develop a. circulating brine resulted in improved cleanliness and reduced fat and milk losses. Production of Margarine and Low Fat Spreads. Advantages of this process are said to include (1) improved, avor release due to the greater surface area of the aqueous phase, (2) the potential, avor levels for baking and cooking into the internal oil phase and at the, avor levels if the product is used as a spread. fatty acid composition of the components available. B. Barmentlo and N. K.

Moustafa (118) has described the composi-, ed. margarines available in the United States has been reported (227). Gunstone and Norris (1983, p. 153) described margarines of different types in relation to the combinations of oils of different iodine values used in their production. Too much of the hard fraction gives too viscous, a product, whereas too little results in oil-off and water separation. 231. Fill temperatures are higher than correspond, 80% fat products because the emulsion is more viscous. J. Henricus, M. Rek, and E. Baas (to Unilever), British Patent 1,358,260, 1974. The product was developed to meet butter shortages caused, by the increasing urban population during the Industrial Revolution, as well as the, need for a table spread with satisfactory keeping quality for the armed forces.

Palm oil is an edible oil derived from the fruits of the oil palm (Elaeis guineensis), belonging to Palmaceae family. While the blending process is taking place, the equipment's sensors and regulating devices keep the mixture's temperature near 100°F (38°C). Pr oduct application Margarine components and industrial production Whether at home or in the industry, hardly another product is as versatile in its range of applications as marga-rine. R. L. Antrim and J. The olein thus obtained was blended, with additional liquid oil to obtain fats suitable for stick margarine. I. Wilton and K. Bauren (to Margarinbolaget), U.S. Patent 3,682,656, 1972.

Either palmitic acid-rich or stearic acid-rich interesterified fats were blended with 13 market samples of hydrogenated (a) Normal, form was favored by higher palmitic acid content in the liquid oil (80). At the present time, it is unknown whether these acids will, eventually be classed as cholesterol-raising fatty acids like saturates or whether, health implications more or less negative than saturates will be attributed to, them. tion of at least part of the liquid oil alleviates this problem. Fats and Oils Used in U.S. Manufacturing Margarine 1980-2002, Â10 6 lb. wrapped prints; however, discoloration may be less apparent than when foil is used, because evaporation occurs from the whole surface rather than from highly loca-, lized areas (289). Protein exerts a destabiliz-, ing effect on water-in-oil emulsions. Practical Applications : Decreasing high fat content food intake has become increasingly popular among consumers. 35. from rice bran oil have been described (63). Grant no. is a platform for academics to share research papers. Omega-3 fatty acids increase bleeding time; decrease platelet aggregation, blood viscosity, and fibrinogen; and increase erythrocyte deformability, thus decreasing the tendency to thrombus formation. P. Seiden (to Procter and Gamble Ltd.), Canadian Patent 718,372, 1965. was devoted to the development of margarines containing high le, acid. In Europe these products are understood by the, consumer to be spreads and not as replacements for full-fat margarine. such as bromophenol-blue, after spreading. Gaonkar, surface-active impurities present in the oil on the vegetable oil, Using microscopy, Heertje (64) found that saturated monoglycerides appear to be, more effective in displacing proteins at the interface than unsaturated monoglycer-. The main problem with practical application of such systems is The drying rate also is affected by temperature and relative humidity, coloration of margarine packed in bowls is not a problem if the container is heat, times is observed to form dark yellow streaks on the surface in the region of ov, on the surface of the product. spreads still make a significant contribution to the fat content of the American diet. It is an important and versatile vegetable oil that is used as a raw material for both food and non-food industries. Salt-tolerant lactobacillus that convert, cient. Flavors obtained by lipolysis of butterfat also are available, and the use of a combination of starter distillate and heat-treated butterfat has been, described (226). There are two primary, methods in use today for measuring the amount of solid fat in an oil blend. One or more of the articles designated in, paragraphs (a)(2) (i), (ii), and (iii) of this section is intimately, mixed with the edible fat and/or ingredients to form a solidi. R. J. Jandacek and J.

Substitution of 75% of lipids in margarine resulted in a product which had higher environmental impact than conventional margarine, but lower than those reported for butter. Suitable, sh oils or palm oils. As more knowledge is gained of mutual solubility, c rearrangement of triglyceride structures are developed, it, . Margarine is a blend of around 80% vegetable oil or animal fat and 20% water with added salt, flavourings, colour and preservatives. The role of emulsi, shortenings has been discussed by Madsen (185). Formulation of low-calorie margarines and spreads using sucrose, octaoleate as a fat replacer has been reported (165, 166).

Thus, in order to meet consumer demands, manufacturers have begun to reduce the fat content of the foods they produce. 0000007831 00000 n Fat Properties Process Conditions Free Trans Product. with scraper blades to study crystallization rates under dynamic conditions. Closed-system packaging equipment needs some modi, to run whipped sticks because of the expansion when line pressure is released at, and appearance (246). It is preferred that the product melts in the mouth and on hot foods, and that it, does not exude water when being spread. 2 = 0.994) and root-mean-square error of prediction (RMSEP = 2.754) display very good overall model performance. Palm oil is a rich source of carotenoids and tocopherols, which confer natural stability against oxidative deterioration. Antioxidants may be necessary for keeping quality of spreads for-, table oil margarines. This is usually accompanied by development of a coarse, sandy texture, consisting of large crystals (Figure 2). A. Roberts (to Procter and Gamble), U.S. Patent 4,446,165, 1984. . Margarine is colored with carotenoids, and synthetic, most widely used. Lecithin may be unbleached or single or double bleached with hydrogen peroxide. Carotene dissolves very slowly in oil. Soft and stick margarines were prepared, with an unhydrogenated hard fraction consisting of an interesteri, coconut oil, palm oil, and palm stearine (145). E. Sambuc, Z. Dirik, G. Reymond, and M. Naudet. 0000025696 00000 n The application margarine and spreads refers to a series of products, which are likened to butter, but have different fat contents. to retard oxidation (228). 58. Because of the greater variety of competitively priced oils and because labeling, of source oils in order of predominance is not generally legislated in Europe, oil, blends are often more complex and interesteri, permit, low percentages of lauric fats sometimes are added for their sharp melting, characteristics (121). These dif, injecting a small amount of the molten fat into the process stream just prior to the, inversion unit after the bulk of the emulsion has been cooled (262).

Heertje (64) has used, scanning electron microscopy and light microscopy to detail the microstructural. … palm oil fractions, and hydrogenated palm oil. Cottonseed, garine producer must realize that the composition of blends received from alternate, suppliers may vary somewhat in crystallization characteristics even though the, tion, solid fat characteristics, and polyunsaturate content of oil blends found in soft, margarines available in the United States. Vegetable margarine contains a water phase and a fat phase and can thus be characterized as water-in-oil emulsions in which the water phase is finely dispersed as droplets in the continuous fat phase. Tropical oils are, viewed negatively by the consumer in the United States, and therefore, they are not, and babassu oils are rich in saturated fatty acids. Title: APYF11 Production of Margarine and Low Fat Spreads_APYF11 Production of Margarine and Low Fat Spreads.qxd.qxd Author: hdesmeules Created Date 0000025771 00000 n In the example in Table 8, nished product characteristics. After the, emulsion is well mixed to ensure uniformity, it is pumped to an agitated holding, ingredients are added to the primary oil storage tank, the two phases can be meter, into the line feed tank or simply mixed in-line using metering pumps or mass, meters. In a study of vola-, tile halocarbons in margarines, Entz and Diachenko (285) generally found less than. The aim of this study is to investigate the volatile release of the butter aroma compounds used in the water phase of model margarine and sensory properties influenced by the change of fat and emulsifier. E. L. Josefowicz and D. Melnick (to Corn Products Company), U.S. Patent 3,457,086. Monoglycerides have been found to hasten the onset of crystallization of various, fats under agitation in the presence of 16% water (109), but lecithin had the, opposite effect (110). Today, with the, development of more spreadable stick margarines and the use of multiple base, stocks, formulation of 100% soybean or corn oil margarines with stable textural, Sandiness develops rapidly when margarine is stored under conditions where, melting and recrystallization of the fat can occur. for the manufacture of soft and stick margarines, respectively. The oil extracted from healthy kernels was barium yellow, whereas, oil, Palmitic acid, a 16-C saturated fatty acid, is important in the production of margarine, shortening, and other fat products. than 2 mg of cholesterol and 2 g or less of saturated fat per serving. Moisture loss during shelf life must also be considered in deter-, with existing net weight regulations. In the absence of rice bran stearin, the emulsions were highly unstable to phase separation with an oil layer forming on their surfaces. 17, Method Cg 2-83, Reapproved 1989. , Publication Number 15, Palm Oil Research Institute. When the emulsion is formed, it is fed via a high-pressure positive, ner emulsion than low speeds (235). Empirical methods, also have been used in attempts to quantify melt-in-the-mouth properties that, depend on both emulsion tightness and the melting pro, the product shows a marked increase in electrical conductivity under shear condi-, tions similar to those that occur on the palate.

Okiy (107) demonstrated that the, triglycerides increases when diglycerides isolated from palm oil are added back, in concentrations from 2% to 15%. Stability was enhanced by homogenization of the aqueous phase. properties, and food uses of lecithin have been reported by Schneider (187). The standard, method (20) for evaluation of hardness of fatty materials uses a cone penetrometer, For some products, hardness measurements may not correlate well with SFI, because, in addition to the amount of solid fat, the fat crystal network, which is, processing dependent, is also important rheologically (21). For example, coconut oil would have a strong positive solids contribution, tionships are bound by the range of mixtures studied and the linearity of contribu-, tions in that range. Due to the increased viscosity, some coarsening of the emulsion may occur during, passage through the working unit (235). In the past, cultured, milk was used in almost all margarines. than 15,000 international units per pound. The production and fortification of margarine is carried out in a batch or continuous process. Improved resistance to oil separation is claimed for a process in which the oil blend, is cooled and held in a quiescent state for at least 5 h prior to adding the aqueous, phase, rechilling, and whipping (120). Melnick and, Josefowicz (120) describe the SFI ranges of a similar liquid product to be 1.5, from Table 6 is used in place of liquid oil, a product with improved oxidati. Many mar-, garine manufacturers purchase blends of colors and vitamins customized for their, There is a wide range of formulations used in the margarine industry today. Erucic acid esters of polyglycerols also were found, to stabilize high internal phase water-in-oil emulsions (203). With an open system the product exits the quiescent tube, impellers feed the margarine to a mold where the print is formed prior to wrapping, and cartoning. The findings of this study are a guide for the production of low‐fat products. Smoothness and brittleness, which depend on the crystal net-, work and are not measured with the cone penetrometer, were measured by means of, an Instron compression test (34). The vanaspati, R1 was always below 10 and R2 was always below 20. II. This kind of product often includes emulsifiers. The approaches, -margarines and spreads has been discussed by. A, pulsed nuclear magnetic resonance (NMR) method for determining droplet size, based on restricted diffusion in droplets has been reported (42, has described a method for microscopically evaluating the size distribution of the, aqueous phase in margarine. distillate can be added. decreased emulsion stability and increased tendency to oil-off. W. G. Mertens, C. E. Swindells, and B. F. 214. Because of the time and space required for, culturing, this practice was largely abandoned in favor of using skim milk together, with starter distillate, diacetyl, or other, some manufacturers in the United States, for the most part has now been replaced, by spray-dried whey, which is sometimes supplemented with potassium caseinate to, a standardized protein content. maximum amounts in percent by weight of the. Extre-, mely low fat spreads have also been prepared from a gelled or thickened aqueous. This, results in a greasy sensation on the palate and little, sing is similar to that described in the preceding section, except that the lower the, fat content, the more critical the manufacturing parameters as, instability. Adulteration of butter with margarine, and later the. In order to minimize the possibilities for oil degradation, it is, optimal to process and deodorize the oil blend at the margarine production, The following section discusses the functionality of some of the ingredients, other, than the fat blend, that are commonly used in table spreads. rst manufactured in 1869 by Hippolyte Mege Mou-, uid fraction obtained in about 60% yield, was then. It was also found that the degree of hydrolysis of shea nut, lifetime of a palm oil sample was reduced from 30 to 4 min after partial gly-, -unsaturated glycerides, particularly 1,3-dipalmitoyl-2-, cation.

Surface darkening occurs when moisture evaporates, leaving an outer, layer enriched in the fat phase that contains the coloring matter. Fats and oils have been used throughout the years in food preparation to provide structure, flavor and nutritive value. In, many plants the aqueous phase is held at 4.4, so that heat may be necessary to maintain the emulsion at a temperature above the, melting point of the fat.
