Description

本発明は、クリーム用油脂組成物及び該油脂組成物を含有するクリームに関し、特に、乳化安定性に優れたクリーム用油脂組成物及び耐熱性と口溶け性に優れたクリームに関する。   TECHNICAL FIELD The present invention relates to a cream oil composition and a cream containing the oil composition, and particularly relates to a cream oil composition excellent in emulsion stability and a cream excellent in heat resistance and mouth meltability.

ホイップクリームは、構成する油脂から分類すると乳脂肪だけからなるクリーム、乳脂肪と植物性脂肪(植物性油脂)を混合したコンパウンドクリーム、植物性脂肪(植物性油脂)のみを使用するクリームの3つに大きく分けられる。   Whipping cream is classified into three types: cream consisting only of milk fat, compound cream containing milk fat and vegetable fat (vegetable fat), cream using only vegetable fat (vegetable fat). It is roughly divided into

これらに使用される植物性油脂としては、ヤシ油やパーム核油などのラウリン系油脂、菜種油、大豆油、パーム油などがあり、これらを硬化、エステル交換、分別などの加工、或いは加工しないで、1種或いは2種以上の混合油として使用されている。   Vegetable oils and fats used in these include lauric fats and oils such as coconut oil and palm kernel oil, rapeseed oil, soybean oil, and palm oil, and these are not processed, such as curing, transesterification, fractionation, or processing. It is used as one or two or more mixed oils.

ラウリン系油脂は、ホイップクリームに口溶けの良さが求められることからよく利用されているが、ラウリン系油脂は温度変化による物性変化が大きく、多量に配合すると耐熱性や耐振性に問題があることが知られている。この問題の解決方法としては、硬化油や極度硬化油の使用などがあげられる(特許文献1、特許文献2参照)。   Laurin-based fats and oils are often used because they require good meltability in whipped cream. However, lauric-based fats and oils have a large change in physical properties due to temperature changes, and if mixed in large amounts, there are problems with heat resistance and vibration resistance. Are known. As a solution to this problem, use of hardened oil or extremely hardened oil can be mentioned (see Patent Document 1 and Patent Document 2).

また、耐熱保形性と口溶け性を改善するものとして、ラウリン系油脂を50〜100質量%(67質量%以下を除く)含み、且つ、SFC値(固体脂含量)が25℃で20%以上、35℃で10%以下である油脂を使用した起泡性水中油型乳化油脂が知られている(特許文献3参照)。
特許3092364号公報 特許3238658号公報 特許3460478号公報
In addition, it contains 50-100 mass% (excluding 67 mass% or less) of lauric fats and oils, and the SFC value (solid fat content) is 20% or more at 25 ° C, as a means to improve heat-resistant shape retention and mouth meltability. There is known a foamable oil-in-water emulsified oil / fat using an oil / fat of 10% or less at 35 ° C. (see Patent Document 3).
Japanese Patent No. 3092364 Japanese Patent No. 3238658 Japanese Patent No. 3460478

Moreover, according to the oil-fat composition of patent document 1 thru | or patent document 3, since the usage-amount of a lauric-type fat cannot be reduced largely, the problem of heat resistance or vibration resistance cannot be wiped off.

そこで、本発明の目的は、乳化安定性に優れたクリーム用油脂組成物及び該油脂組成物を含有する耐熱性と口溶け性に優れたクリームを提供することにある。特に、本発明の目的は、温度依存性の高いラウリン系油脂の配合量を少なくして、且つ、クリームの口溶け性を改良することのできる、クリーム用油脂組成物及び該油脂組成物を含有するクリームを提供することにある。   Then, the objective of this invention is providing the cream excellent in the heat resistance and the mouth meltability containing the oil-and-fat composition for creams excellent in the emulsion stability, and this oil-and-fat composition. In particular, an object of the present invention is to contain an oil composition for cream and the oil composition that can reduce the blending amount of lauric oil having a high temperature dependency and improve the meltability of cream. To provide a cream.
