Description

  The present invention relates to a plastic fat composition excellent in gloss and mouthfeel.

  The plastic fat composition having plasticity is suitable for applications such as kneading, folding, spread, coating cream and sand cream. Examples of the plastic fat composition include margarine, fat spread and shortening.

  Conventionally, various hydrogenated oils of various raw oils have been used for plastic fat compositions because of their good processability. On the other hand, the partially hydrogenated oil contains trans fatty acid. Due to the health problems caused by trans fatty acids in recent years, it has been strongly demanded to reduce the content of trans fatty acids even in plastic fat compositions.

  In order to reduce the trans fatty acid content of the plastic fat composition, use of palm oil or palm kernel oil, which is a natural solid fat substantially free of trans fatty acid, has been promoted. However, so-called palm-based fats and oils, which are palm oil and its fractionated oil, have a tendency to coarsen fat crystals over time, and there is a difficulty in their use. Moreover, lauric fats and oils such as palm kernel oil and coconut oil have a good mouthfeel, but have a narrow temperature range in which plasticity can be maintained. Therefore, the compounding quantity to the plastic fat composition of a lauric fat is limited.

  In order to overcome the above disadvantages, transesterified fats and oils using palm oil or palm kernel oil as raw material fats and oils have also been developed. For example, Japanese Patent Application Laid-Open No. Sho 62-81497 proposes margarine using a fat obtained by transesterification of a mixed oil of a fat derived from palm oil and a fat containing a saturated fatty acid having 22 carbon atoms. However, even when such a transesterified oil and fat is used, the glossiness of margarine, which is a plastic oil and fat composition, is easily lost over time.

  Further, as a method other than transesterification, attempts have been made to suppress the crystal growth of palm-based fats and oils by adding various emulsifiers (for example, JP-A Nos. 62-205738 and 5-199838). Gazette and JP-A-9-176680). However, the use of these emulsifiers tends to increase the amount of the emulsifier, and there are difficulties in flavor and mouthfeel. Moreover, the glossiness of the plastic fat composition containing palm-based fats and oils is also easily lost over time.

  Moreover, when the content of the liquid fat / oil in the whole fat / oil contained in the plastic fat / oil composition is increased, the glossiness tends to be improved. However, oily taste remains in the mouth, and the mouth is apt to deteriorate.
