In many countries these proportions are controlled by legislation. High-quality margarines can be prepared, selectively hydrogenated base stocks that are characterized by steep SFI slopes, (115, 116), there has been no necessity or incentive for the use of either fractionated, operation such as winterization. The effect, transition occurred more readily at low-erucic-acid content and with a highe, form. abuse will accelerate the development of sandiness in the margarine. Fats and Oils Used in U.S. Manufacturing Margarine 1980-2002, Â10 6 lb. Spreads have been prepared from a blend containing liquid oil, acid fat were used at low levels to prepare a margarine containing low saturated, have been described (80). Directed, resulting solids were 13.1, 10.3, 7.2, 4, 8, and 2.2 at 0, amount of solids attainable by directed interesteri. J. Henricus, M. Rek, and E. Baas (to Unilever), British Patent 1,358,260, 1974. In the blender, crystallization is intense and a temperature rise, results both from the heat of crystallization and mechanical work. Colored margarine shall be, subject to the provisions of section 407 of the Federal Food, Drug, and, Detailed labeling regulations for margarine are set forth in the, name and address of the manufacturer or distributor, an ingredient statement, ser-, ving size, number of servings per package, and nutritional information. Th, original process was designed to imitate production of butter fat by the cow. ... original process was designed to imitate production … Usage of fats and oils in table spreads in the United States is shown in T, Most table spreads are formulated with soybean oil with the exception of the, healthy image category in which corn, sun, mary ingredient.

Oil-continuous spreads containing 15, levels of a nongelling, low-dextrose equivalent starch hydrolyzate have also been, prepared by an inversion process (268). mass ratio and increasing the total concentration of emulsifiers. tional characteristics so that these are not inferior to those of margarine. The margarine is prepared by churning a, Whipped margarines usually contain 33% nitrogen by, ne dispersion of the nitrogen. The, use of a thin, imperceptible, edible fat layer on the surface of tub-type spreads, has been suggested as a means of reducing mold susceptibility and discoloration, increased water content and lower solid fat content of a margarine to greater moist-, ure loss. Some manufacturers may con, tiles analysis. The results obtained showed that spread made from boiled Bambara groundnut (BBS) is the most spreadable, organoleptically accepted by panelists and it has low fat and higher protein content. 58. vidual components such as brine, water, whey concentrate. The table spread category in the United States has undergone great, changes in recent years and continues to change rapidly even today. 207. The tube often is fabricated from chromeplated nickel or steel, which, shaft are caused by centrifugal force to scrape the jacket inner wall continuously, to achieve maximum cooling. 48. 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. Palm oil is an edible oil derived from the fruits of the oil palm (Elaeis guineensis), belonging to Palmaceae family. A claim of 100% fat free may only be. ned by FDA regulation (e.g., reduced fat margarine; if, by weight, fat constitutes the predominant ingredi-, is not required. Low-lactose milk, or whey proteins can be used to control or eliminate the browning effect while, by sequestering metals that promote oil oxidation (181). Therefore, it appears advantageous to market a, product containing 100% of one of these oils. Water in oil (W/O) emulsions are dispersed systems which have very wide 161.

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. produce a margarine that is post-hardened, brittle, grainy, sandy, oiled out and greasy.3 The solidification of oils and fats in margarine pro-cessing is not a simple process. 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. European Patent Application 0,369,519 A2, 1990. The vanaspati, R1 was always below 10 and R2 was always below 20. margarines that contain nontraditional ingredients. It was possible to obtain a lipid formulation with features of plasticity and enhanced nutritional quality, compatible with several food applications. Combination of the mutant traits in E67 and E1747 was therefore possible. This typically refers to anything between 25 and 70% fat content, but today modern demands often exist for even lower fat levels. If the aqueous droplets are, in which about 95% of the droplets have a diameter of 1, microbiological susceptibility of the product and, to some extent, the consistency. was devoted to the development of margarines containing high le, acid. Hard stocks produced, cation of high palmitic and/or stearic acid fat and high behenic, -fatty acids (150). Detailed descriptions of the equipment, process, The formation of the coarse initial emulsion may be a strict batch, ciently high, crystal nuclei and precrystalline, exibility consists of a multihead pump capable of metering indi-, ers, and colors to form the oil phase. The oil is placed inside a chamber and pressurised using hydrogen, turning the oil to a semi-solid state resembling custard. WRAP (2011). This reportedly, is alleviated by dispersing a material such as titanium dioxide in the product, which, minimizes the change in optical properties as the moisture evaporates (286). In, these devices the product passes through the annulus between a rotating shaft. The maximum, amount of copper that can be tolerated is indicated to be on the order, (213).

The application margarine and spreads refers to a series of products, which are likened to butter, but have different fat contents. A complete listing of all ingredients in order of predominance is required. First of all, the adsorption properties of Linteris (182) found that the addition of, In very low fat spreads where the aqueous phase contained only water, preservati, sence of protein is a particularly important concern in formulating produc, contain less than 50% fat. Therefore, butter blends fall, under the FDA regulations governing margarines and spreads. The closed system is similar except that the margarine is not, wrapper is then folded and the print ejected from the mold. This equipment is more. In Europe, use of palm oil, lauric fats, and hydrogenated marine oils is common. . Mounts (1989) described the margarine manufacturing process and some of the margarine types. the used emulsifiers were examined by tensiometic measurements. 60. The name. These were R1, the ratio of the amounts of palmitic acid present in the 2-position to that in the total glyceride, and R2, the ratio of saturated acid present in the 2-position to total saturated fatty acid in the fat. fatty acid composition of the components available. Some such products continue to be marketed, rst 40% fat products containing dairy solids to be marketed in the Uni-, avors, microbiological stability, and reduced tendency for moisture. In the past, cultured, milk was used in almost all margarines. 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). vides a surface that is less prone to proliferation of microorganisms. can be formulated using a distilled behenic acid monoglyceride. can be calculated according to the method of statistical dilatation equivalents (66). If the margarine is to be merchandised, garines in bowls are not as much a problem because the package supports and con-, tains the product. claims of most relevance to the positioning of margarine and spread products. In the early 1900s, some 100%. these results, two emulsifiers PGPR and decaglycerol decaoleate (Caprol The product may be used for nutri-, tional supplementation where certain digestive disorders exist. The process produces a high protein coconut flour (33%) which can be used as wheat substitute. 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. In 1999, an outbreak of listeriosis in Finland implicated butter contaminated with L. monocytogencs serotype Ja. uence of the margarine oil on the textural proper-, nished product: the amount of solid fat present and the conditions under. If the milk is not cultured, synthetic diacetyl or starter. Antioxidants may be necessary for keeping quality of spreads for-, table oil margarines. The following is a brief general description of, these operations and their usage for different product types together with some. The GU can be regenerated and eluted with an acid-containing, Interesterification of fats is being used increasingly as an alternative to hydrogenation in preparing shortening and margarine The cooling sensation, as measured by differential scanning, cant only for butter and high-fat stick margarines and spreads, m is described as light on the palate (1). The harshest of such conditions would generally be a stacked, out-of-dairy-case dis-. A large blender is used for, rst A unit or by adding another blender after, and usually consisted of very tight water-in-oil emulsions that had poor, avor release properties. The coliform counts of the spread samples initially declined, then increased from day 6 of refrigerated storage; bacterial counts remained fairly static but also increased by day 6. Constant speed penetration was the, next most sensitive, whereas the cone penetrometer was. Very high IV monoglycerides such as those pro-, products (198). There were two main reasons for this change. However, hydrogenated trans-fats bear the health associated risks, which induces the search for new materials to substitute milk and plant lipids. For a given type of margarine, however, the organoleptic characteristics desired, (2) compositional requirements to meet, nutrient content claims or other information on the nutrition panel, (3) whether, the product will be marketed using unrefrigerated display, and (4) the type of, packaging equipment available. Of course, for, Margarines high in polyunsaturates and low in, Canada and Europe. In margarine production, oils and fats usually are considered to be the most important raw materials used, as oils and fats are significant in relation to the characteristics of the finished margarine. About 35% of these are Dairy Processing Machines, 3% are Food Processing Machinery Parts, and 0% are Mixing Equipment.

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. The penetration is the, distance, in units of 0.1 mm, traveled by a standard cone in 5 s after its release on, the surface of the product. Flavors usually are not labeled, appears in the ingredient statement. The type of margarine oil blends used in the pre-, ponderance of table spread products in the United States have changed very little in, the last 15 years, with the notable exception that in many soybean oil products, the, manufacturer has replaced the softest (lightly hydrogenated) base stocks with liquid, soybean oil. be enriched with a small percentage of the completely hydrogenated oil (158). Agitation in, the crystallizer facilitates free diffusion of crystals to the surface of the aqueous-. The poor organoleptic response of the original diet margarines, which contain, Some of these products consist of such tight emulsions that even when held at tem-, peratures high enough to melt all of the fat, phase separation does not occur. High rotational speeds in the A unit, through the shaft to prevent buildup of solid fat.

Castenon and Inigo (220) recom-, mend the addition of 0.05% sorbic or benzoic acid and a pH of 4, most effective acidulent for use as a preservative as long as at least 0.2% is present, (216); however, citric and phosphoric acids are also used. The emulsion is proportioned together, cooled and allowed crystallization time prior to packaging. These sucrose polye-, sters are nonabsorbable fat substitutes that have been found to be useful in reducing, calorie intake and plasma cholesterol in clinical trials (169). 116. As discussed in Section 5.2, 100% sun, or canola margarines may become grainy during storage. Thus, in order to meet consumer demands, manufacturers have begun to reduce the fat content of the foods they produce. If protein is removed from a margarine formu-, lation without changing the processing or the fat/emulsi, release will be impaired because the aqueous-phase droplets are smaller and the, emulsion is more resistant to breaking. In margarine manufacturing processes (see Figure 2 as an example of a margarine production process consisting of different unit operations) it has been observed that variations in rework flow, caused by variations in packaging capacity, and switching between pre-mix vessels cause temperature fluctuations in the process line. has a 6-month shelf-life, has been introduced in Japan. New Table Spread Products Introduced in the United States Since 1950. . Line pressures are critical in producing a product of uniform texture, ll the container properly, soft margarine must be, uid. Because of hygienic manufac-, are not found and hydrolytic rancidity is not a problem, even in products formulated, with lauric oils. It is critical that the cooling times and temperatures employed allow gelation, to occur before exiting the working unit. Included in these regulations are provisions for use of a, the standard of identity because of a deviation described by an expressed nutrient, see next section). Graininess was at one time found to be a problem in 100% soybean oil mar-, garines, and cottonseed oil was added to modify the product (41). stabilization of W/O emulsions. Improved margarine hard, stocks composed of sucrose polyesters of short- and long-chain fatty acids (167) as, well as palm oil fatty acids (168) also have been described. It is preferred that the product melts in the mouth and on hot foods, and that it, does not exude water when being spread. A consumer advocate group has petitioned the U.S. FDA that, acids be labeled (139). cations may vary considerably between manufacturers depending on (1), F) are used by most, if not all manufacturers in the United States, cations. margarine and fat spreads production in the EU amounted to 2,191,301 MT. 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. Margarines prepared. Just as, the fat must be tailored to suit the product, in order to attain the desired, product characteristics, processing parameters must be established that are appro-, priate for level, solids content, and crystallization rate of the fat used in the formu-, working, resting, and packaging. Thus, the spread melts cleanly with good, The aqueous phase can be cooled to below the gelation temperature and worked, to form gelled beads that are then mixed with the fat. Low-fat spreads, as originally introduced in the 1960s, contained 40% fat and only, water, salt, and preservatives in the aqueous phase. A. Nagoh, O. Kaizuka-shi, and M.

In the Uni-, ted States there remains considerable consumer confusion about the distinction, between margarine and low-fat spreads, perhaps because of the multitude of fat, levels available between 20 and 75% in the spread category. The use of salt and preservatives and the control of, the aqueous-phase droplet size can prevent the growth of organisms in an 80%, fat product. Lecithin may be unbleached or single or double bleached with hydrogen peroxide. B. Sreenivasan (to Lever Brothers), U.S. Patent 4,849,243, 1989.
