Description

[Detailed description of the invention] The present invention relates to a hard putter and a method for manufacturing the same.

Hard putter is also called a substitute cacao butter, and like cacao butter, it is hard at room temperature and quickly brews at temperatures around body temperature. It is mainly used for chocolate-like confectionery and coatings for baker products. ing. This hard putter is roughly divided into cacao butter for tempering and cacao butter for non-tempering. The present invention relates to a hard putter with non-tempered wrinkles. This hard putter does not require tempering operations in the manufacturing process of chocolate, etc., and is generally cheaper than the former, so
It has a wide range of uses as a confectionery fat. However, a drawback is that when a large amount of cocoa butter is mixed, a plume is likely to occur. Moreover, in order to improve the flavor of the chocolate product, K must use a chocolate licker containing a large amount of ζ゛cocoa fat.

The present inventor previously discovered a method for producing a hard putter that has the advantages of having a smooth texture and not producing a soapy odor by transesterifying myristate triglyceride with a specific oil and fat (Japanese Patent Laid-Open No. 55-58060). ), even if such a hard putter KTo has a high content of cocoa butter, it will be 7.
The occurrence of hot plumes was no longer completely suppressed.

It is generally believed that the 7-hot plume is caused by a change in the crystalline form of fats and oils. This crystal type is related to the triglyceride composition. Non-tempering hard putters are manufactured using soybean oil, cottonseed oil, corn oil, palm oil, etc. as raw materials through processes such as transesterification, selective hydrogenation, and solvent fractionation, and their fatty acid composition is balmitic acid (016). , stearic acid (0□, ), elaidic acid (
It is a triglyceride mainly composed of 11=1 (0, trans), and generally takes the β' form as its crystal form. On the other hand, cacao butter is mainly composed of β-oleodystearin and is a stable crystalline form of nine oils and fats. When both are melted and mixed and cooled, the crystal form immediately after solidification is the β' type, and if the amount of cacao butter is small, it will remain unchanged for a long time, but if the content of cacao butter increases, the cacao butter will change. It is estimated that βgK translocates and becomes a cause of fat bloom.

The present inventor has conducted extensive research with the aim of obtaining a hard putter in which the crystal type remains in a'm even when a relatively large amount of cacao butter is blended, resulting in less fat bloom. I was inspired by the invention.

The hard putter of the present invention is made of fatty acid triglyceride fats and oils, and the constituent fatty acids are (&) lauric acid (
(1) docosamonoenoic acid ('H=1*) lance (pracudic acid) or cis (erucinic acid) 10 to 20% by weight (1)) 20 weight bags, (0) the remainder is essentially palmitic acid (0□6), stearic acid (01,
) and octadecenoic acid (0 □l=s, cis (thleic acid) or trans (elaidic acid)), and the total amount of saturated fatty acids is 40% by weight or less, preferably 30 to 40% by weight of ginseng oil and fat. Melting point is 54-40℃, solid fat index at 10℃ is 50 or more, solid fat index at sO℃ is 2
It has characteristics of 5 or more.

The constituent fatty acids of the fat and oil of the present invention are substantially only those mentioned above, and the amount of other fatty acids is 5 or less. A hard putter having the above fatty acid composition and characteristics is most preferably made of lauric acid alone. Triglycerides (
trilaurin), triglyceride of myristic acid alone (
trimyristin) or a mixed triglyceride of lauric acid and myristic acid, rapeseed oil with a high erucic acid content or selective hydrogenation of this under conditions that increase the production of trans acids, palm oil, corn oil ( (corn oil), oils and fats with a high content of palmitic acid, stearic acid, oleic acid, linoleic acid (O1 g = 2) such as rapeseed oil, synthetic triglycerides made of these fatty acids, or mixtures thereof. Transesterification is then carried out, and if necessary, selective hydrogenation is performed under conditions that increase the production of trans acids. Rapeseed oil with a high content of erucic acid is extracted from rapeseed cultivated in Japan and parts of Me-Rotsuba, and contains 30 to 30% of erucic acid in fatty acids.
Contains 50 kg. Oils and fats such as palm oil, corn oil, and rapeseed oil may be selectively hydrogenated in advance under conditions that increase the production of trans acids, and selective hydrogenation may be performed after transesterification. The method of selective hydrogenation that increases the production of trans acids is known by Saka et al., and uses a sulfur-poisoned nickel catalyst or a nine-element nickel catalyst supported on diatomaceous earth.
Hydrogen pressure 01~Ish/cab2, preferably 0, 1
Hydrogenation is most typically carried out under conditions of ~11 #/cy*' and a temperature of 160 to 220°C. Transesterification can be carried out according to a conventional method, using a lower alcohol with an alkali metal alkoxide (for example, F methoxide).

The most suitable method is to use a catalyst such as potassium ethoxide (such as potassium ethoxide) or an alkali metal hydride at a temperature of 60 to 150'C in a nitrogen stream. The amount of catalyst used is
In any case of transesterification, the amount of oil or fat is 0.1~
◇In the present invention, hydrogenation is
It is preferable that the final amount of trans acid is 50 to 55. Here, the amount of trans acid means 1 unsaturated fat for the hard putter of the present invention, which is substantially '11.1, ○, =
