Embodiment 1

[0075] Embodiment 1: the preparation of lard

[0076] The subcutaneous fat of live pigs is selected after being cleaned and placed in an environment of 150-190°C for boiling, the oil is squeezed out, and after conventional impurity removal and refining treatments, the iodine value is 60-62gI / 100g and the melting point is 40- lard 1 at 42°C; and lard 2 with an iodine value of 68-70gI / 100g and a melting point of 30-32°C.

Embodiment 2

[0077] Embodiment 2: the preparation of palm oil

[0078]Choose commercially available palm oil (iodine value 50-52gI / 100g, melting point 32-34 ℃) as raw material, adopt conventional dry fractionation method to carry out two fractionation, obtain iodine value 33-35gI / 100g of palm stearin with a melting point of 50-55°C; then use the palm stearin for the second fractionation to obtain the fractionated stearin. Control the crystal growth temperature, time and filter pressure of the second sub-extraction to obtain iodine value of 8-10gI / 100g, melting point of 58-60°C palm oil 1, iodine value of 33-35gI / 100g, melting point of 50-52°C palm oil 2, iodine value 22-23gI / 100g, palm oil 3 with a melting point of 56-58°C.

Embodiment 3

[0079] Embodiment 3: the preparation of plastic oil composition (anhydrous type margarine)

[0080] Control group 1 (Sunshine brand anhydrous ghee produced by Kerry Special Oils (Shanghai) Co., Ltd., sold in winter, spring and autumn, and belongs to water-free margarine)

[0081] The oil raw material of control group 1 is mainly palm kernel oil and palm oil, obtains corresponding oil mixture after oil modification, this oil mixture is sent into mixing tank and stirred and mixed, then add auxiliary materials (essence, Pigment, antioxidant, emulsifier) ​​are stirred and mixed, then sent to a quencher for conventional quenching treatment, then sent to a kneader for conventional kneading treatment, and finally conventional aging treatment (aging at 15-40°C for more than 2 days).

[0082] Control group 2 (Sunshine brand anhydrous ghee produced by Kerry Special Oils (Shanghai) Co., Ltd., sold in Xia Chunqiu, belongs to water-free margarine)

[0083] The production method of control...

Abstract

The invention relates to an oil composition and a method for preparing the same. The oil composition contains lard oil and palm type oil, wherein the iodine value of the lard oil is 60-70gI / 100g, the melting point of the lard oil is 30-42 DEG C, the iodine value of the palm type oil is 8-35 gI / 100g, and the melting point of the palm type oil is 50-60 DEG C. The oil composition disclosed by the invention can be used for various plastic oil products comprising margarine, shortening and the like and has the advantage of wide plastic temperature range.

Description

technical field [0001] The present invention relates to the field of oil composition. Specifically, the invention relates to a fat composition with a wide plasticity temperature range and a preparation method thereof, and the fat composition is especially used in plastic fat products. Background technique [0002] With the development of the baking market, plastic oil products such as margarine and shortening are widely used. [0003] In the use of plastic oil products, the more critical indicators include plasticity and the temperature range for maintaining better plasticity. For traditional plastic oil products, the temperature range for maintaining their optimal plasticity is generally very narrow (for example, the span of the best plastic temperature range for margarine currently on the market is generally 10-15 degrees Celsius). When the temperature is lower than the span range, its plasticity is not good (when the temperature is lower than the span range, the oil har...
