Definitions

  • the present invention relates to a novel oil and fat composition for food processing machines. More particularly, the present invention relates to a novel oil and fat for food processing machines which is safe for food sanitation, has excellent lubricating property and antioxidation property and is favorably utilized for machines and tools for food processing, machines and tools for agriculture and like other machines and tools.
  • Examples of the machines for processing of agricultural products are machines and tools for collecting leaves from tea plants, rice cleaning machines, flour mills, brewing apparatus for production of sake, soy sauce, miso and like others and machines for production of noodle, bread, cookies, fruit juice, jam, pickles and like others.
  • Examples of machines for processing of livestock products are machines for processing milk, machines for production of milk products, such as cheese and butter, machines for processing meat and like others.
  • Examples of machines for processing of marine products are machines for processing of fish meat, sea weeds and like others.
  • Other examples of the food processing machines are apparatus for production of food additives, natural flavor and pharmaceutical products, such as a vacuum thin layer evaporator and a mixing apparatus.
  • oils of mineral origin such as mineral oil and liquid paraffine
  • liquid vegetable oils such as soy bean oil, cotton seed oil and rapeseed oil and animal oils and fats, such as beef tallow and lard
  • oils of mineral origin it is unavoidable that the oils are scattered or mixed into the foods or the agricultural products through rotating parts of the machines during long operation of the machines and the scattering and mixing of the oils of mineral origin into the foods and agricultural products are not desirable food sanitation.
  • liquid vegetable oils or animal oils and fats are utilized, oxidation stability is not sufficient even though they do not have problem on food sanitation.
  • oils and fats have been proposed as materials useful for food processmg machines: (1) oil and fat utilized for spraying which comprise a transesterification product of 30 to 90 weight parts of oil and fat for foods containing less than 20 weight % of saturated fatty acid and 70 to 10 weight parts of a composition containing a triglyceride of medium chain saturated fatty acids having 6 to 10 carbon atoms (MCT) as the main component (Laid Open Japanese Patent Publication Showa 56-72651); (2) a transesterification product of oil and fat made to contain increased amounts of monoene acids, such as oleic acid, and decreased amounts of polyene acids, such as linoleic acid and linolenic acid, by hydrogenation of vegetable oils, such as camellia oil, sasanqua oil, olive oil, safflower oil of high oleic acid content, hazelnut oil and rapeseed oil (Laid Open Japanese Patent Publications Showa 57-67695 and Showa 62-32841); (3) an oil of
  • oils and fats of (1) through (3) contain large amounts of unsaturated acids such as oleic acid because they utilize soy ben oil, cotton seed oil, rapeseed oil, corn oil or oils which were made to contain increased amounts of oleic acid by reducing content of polyene acids by hydrogenation to enhance oxidation stability and have a problem that oxidation stability is not sufficient.
  • Another material proposed is a lubricating oil composition for food processing machines prepared by compounding triglycerides having linear alkyl group of 5 to 21 carbon atoms as the essential component and fatty acids of 12 to 22 carbon atoms (Laid Open Japanese Patent Publication Heisei 2-209995).
  • this composition is based on the low viscosity MCT and has a problem that adjustment of the viscosity of the composition to a desired value is not always easy.
  • Rate of oxidation of unsaturated fatty acids is large than rate of oxidation of saturated fatty acids.
  • the rates of oxidation of linoleic acid and linolenic acid at 20°C are 12 to 20 times and 25 times, respectively, larger than the rate of oxidation of oleic acid.
  • Esters of saturated fatty acids are stable against oxidation.
  • the rate of oxidation of methyl stearate at 100°C is 1/11 and 1/100 of methyl oleate and methyl linolate, respectively.
  • Oxidation stability and cloud point are, in general, related with each other. Oils and fats which contain larger amounts of unsaturated acids having higher oxygen absorption, such as oleic acid, linoleic acid and linolenic acid, in glyceride have lower oxidation stability and also a lower value of cloud point. Cloud point, pour point and solidifying point are also, in general, related with each other and a material having a higher cloud point has a higher pour point and a higher solidifying point. Property of a material can be compared by utilizing either one of cloud point, pour point and solidifying point.
  • An oil which is prepared by transesterification of MCT and an oil containing a large amount of oleic acid in which the contents of linoleic acid and linolenic acid are reduced by hydrogenation to enhance oxidation stability has a lower cloud point but is not sufficient in oxidation stability because oleic acid is also an unsaturated fatty acid.
  • Oils and fats containing larger amounts of saturated fatty acids having lower oxygen absorption, such as myristic acid, palmitic acid, stearic acid and the like, in glyceride has higher oxidation stability but higher cloud point at the same time.
  • MCT which is considered to be the best material for the lubricating oil for food processing machines has satisfactory quality concerning high oxidation stability and low cloud point.
  • MCT has too low viscosity when it is utilized without other components because the viscosity is 15 to 20 centipoises at 25°C and 10 to 15 centipoises at 40°C.
  • the present invention accordingly has the object to provide an oil and fat composition for food processing machines which is safe for food sanitation, has excellent oxidation stability, good lubricating property and suitable degree of cloud point as well as a high viscosity and a low temperature fluidity which cannot be attained by MCT and is applied to driving parts of food processing machines and tools, such as chains and shafts, by dropping, by spraying as aerosol, by spraying with a pump and by the like methods.
  • the invention concerns the Use of an oil and fat composition
  • the present inventors investigated extensively to prepare oil and fat compositions for food processing machines having the advantageous properties to achieve the object described above and discovered that the above-defined use is effective for achieving the object of the invention.
  • the polyglyceride of medium chain saturated fatty acid is a polyglyceride prepared from a medium chain saturated fatty acids and polyglycerol.
  • the medium chain saturated fatty acid are saturated fatty acids having 6 to 10 carbon atoms, such as caproic acid, heptylic acid, caprylic acid, nonylic acid, capric acid.
  • the medium chain saturated acid can be utilized singly or as a combination of two or more kinds.
  • the mixed polyglyceride of a medium chain saturated fatty acid and a long chain saturated fatty acid is an ester of a mixed fatty acid comprising a medium chain saturated fatty acid and a long chain saturated fatty acid and a polyglycerol.
  • Examples of the medium chain saturated fatty acid are the same as the examples of the medium chain saturated fatty acid for MCP described above.
  • the long chain saturated fatty acid are lauric acid, myristic acid, palmitic acid, stearic acid and the like.
  • the mixed fatty acid may be a mixture of more than one kind of fatty acids suitably selected from the group of the medium chain saturated fatty acids and the long chain saturated fatty acids or an oil prepared by saponification of extremely hardened oil which is prepared by hydrogenation of a vegetable oil, such as soy bean oil, rapeseed oil, palm oil, palm kernel oil, corn oil, coconut oil and the like, or animal fat and oil, such as lard, beef tallow, fish oil and the like.
  • a vegetable oil such as soy bean oil, rapeseed oil, palm oil, palm kernel oil, corn oil, coconut oil and the like
  • animal fat and oil such as lard, beef tallow, fish oil and the like.
  • coconut oil comprising various kinds of fatty acids, such as capric acid, caprylic acid, lauric acid, myristic acid, palmitic acid, stearic acid and the like, is utilized as the raw oil for hydrogenation.
  • MLCP can be prepared either by esterification of the mixed fatty acid with polyglycerol or by transesterification of MCP with the extremely hardened oil prepared by hydrogenation of the vegetable oils or animal fats and oils, preferably with the extremely hardened oil prepared from coconut oil.
  • Viscosity of MCP and MLCP can be adjusted by suitably selecting the saturated fatty acids utilized. Emulsifying property and compatibility with water are enhanced by leaving a suitable amount of unreacted hydroxyl group in glycerol by keeping degree of saponification below suitable level and thus the composition of the invention can be washed off, when necessary, from food processing machines easily.
  • MCP and MLCP have rather high viscosities.
  • the viscosity can be adjusted to a desired level by mixing MCT according to necessity.
  • MCT can be prepared from medium chain saturated fatty acids and glycerol. Examples of the medium chain saturated fatty acid are the same as the examples of medium chain saturated fatty acid for MCP.
  • oil and fat composition for food processing machines of the invention does not comprise unsaturated fatty acid component, it has excellent oxidation stability, suitable viscosity and cloud point, good lubricating property and is safe for food sanitation.
  • antioxidants such as tocopherol, 2,6-di-t-butyl-4-methylphenol and the like, fatty acids as the rust preventing and abrasion preventing oil agent and emulsifying agents to facilitate washing off the composition from food processing machines may be added according to desire.
  • compositions prepared were evaluated by the following methods.
  • Oil and fat compositions shown in the following were prepared from a nona ester utilized as MCP which was prepared from a mixed fatty acid of 75 weight % of caprylic acid and 25 weight % of capric acid and decaglycerol and a triglyceride of a mixed fatty acid of 75 weight % of caprylic acid and 25 weight % of capric acid utilized as MCT.

After the catalyst was removed from the reaction mixture by washing with warm water, the mixture was bleached by activated clay and deodorized by vacuum steam distillation according to the generally practiced method. Thus, MLCP was prepared.
  • Example 5 90 weight % of MCP and 10 weight % of an extremely hardened oil based on rapeseed oil, in Example 6, 90 weight % of MCP and 10 weight % of an extremely hardened oil based on lard and in Example 7, 60 weight % of MCP and 40 weight % of an extremely hardened oil based on coconut oil, respectively, were treated by transesterification.
  • rapeseed oil in Comparative example 1, rapeseed oil, in Comparative example 2, a triglyceride of a mixed fatty acid of 75 weight % of caprylic acid and 25 weight % of capric acid, in Comparative example 3, liquid paraffine and, in Comparative example 4, MCT, respectively, were evaluated by the same method as in the preceding examples. Results of the evaluation are listed in Table 1.
  • the oil and fat composition for food processing machines is safe for food sanitation, has excellent oxidation stability and lubricating property and a suitable degree of viscosity and cloud point as well as a high viscosity and a low temperature fluidity which cannot be attained by MCT and is applied to driving parts of food processing machines and tools, such as chains and shafts, by dropping, by spraying as aerosol, by spraying with a pump and by the like methods.
  • the amount of the the polyglyceride and/or the mixed polyglyceride is preferably 30 weight % or above, more preferably 40 weight % or above and the amount of the triglyceride is preferably 70 weight % or less, more preferably 60 weight % or less.
  • Example 6 145 0.35 no rust 160 2
