Problems solved by technology

[0006] Palm oil is semi-solid to solid at room temperature. If it is used as a raw material for the production of plastic oil, although it can solve the above-mentioned requirements of solid fat content SFC and low trans, it also brings some problems, such as reducing the crystallization of oil The speed greatly prolongs the final aging step of plastic oil production (that is, the cooling and crystallization of finished oil products, usually at room temperature), reduces production efficiency, and brings inconvenience to the industrial production of plastic oil

Embodiment 1

[0104] Preparation of Sandwich Oil 1

[0105] Palm Kernel Olein (PKOL) (IV: 22, purchased from Kerry Special Oils (Shanghai) Co., Ltd., IV is iodine value) and palm stearin (Palm Stearin, ST) (IV: 34; purchased From Kerry Special Oils (Shanghai) Co., Ltd.) in a weight ratio of 25:75. Example 1 See Table 1 for fatty acid composition of oil raw materials palm kernel liquid oil PKOL and palm stearin ST.

[0106] Vacuum dry the mixed oil and fat raw materials (stir in vacuum, heat up to 105°C, keep for 1h); then add 0.8% catalyst sodium methoxide, react at 100°C for 45min; then add 8% citric acid aqueous solution, stir for 30min, The reaction was terminated, and then the reactant was washed with water until the pH was 7, and then centrifuged to obtain transesterified oil.

[0107] Then carry out oil refining operation on the obtained transesterified oil: vacuumize and heat the transesterified oil to 105°C, keep it for 30min, dehydrate and dry; then add 2% activated clay, keep it...

[0117] Preparing shortening 1

[0118] Raw materials PKOL (IV=24) and ST (IV=39) were mixed in a ratio of 10:90. Example 2 See Table 4 for the fatty acid compositions of the oil and fat raw materials PKOL and ST.

[0119] The preparation and refining process of transesterified fat are the same as in Example 1.

[0120] After oil melting, rapid cooling, kneading, and aging treatment (according to the conventional production method of margarine), the product shortening 1 is obtained, and its fatty acid composition (accounting for total fatty acid) is shown in Table 4, and its triglyceride composition (accounting for the total amount of sandwich oil) is shown in Table 4. Table 5, see Table 6 for the solid fat content at each temperature (accounting for the total sandwich oil), and see Table 16 for the crystallization rate (10° C.) of the aging step of shortening 1.

Abstract

The invention relates to an oil composition, a composite oil composition compounded by the oil composition and natural plant oil, and a plastic oil product thereof. The oil composition comprises a triglyceride composition obtained by transesterification treatment. Oil raw materials adopted by the transesterification treatment comprise natural plant oil or its distillate oil. Weighed according to the weight of total fatty acids which form the oil composition, the content of saturated fatty acid is 50-80%, wherein the content of saturated fatty acid with its carbon atomic number being 12-14 is 5-35% and the content of saturated fatty acid with its carbon atomic number being 16-18. Weighed according to the gross weight of the oil composition, the content of three-phase saturated triglycerides containing three saturated fatty acids within molecules is 40-65%. The solid fat content of the oil composition at 25-30 DEG C is 10-52%, preferably 30-10% or 52-25%. The oil composition and the composite oil composition can be used to prepare the plastic oil, which has advantages of low trans-fatty acid content and fast crystallization rate. The invention also provides preparation methods of the above oil composition and the composite oil composition.

Description

technical field [0001] The invention relates to an oil composition; more specifically, it relates to a plastic oil composition with low trans fatty acid content and fast crystallization rate. Background technique [0002] For industrial production of oil compositions, especially plastic oil compositions such as margarine and shortening, in order to meet specific application requirements, it is usually necessary to meet certain operational performance indicators. For example, one of the more important performance indicators is solid fat Content (Solid Fat Content, SFC), specifically, refers to the melting and hardness performance indicators of fat at different temperatures, and the melting and hardness performance have a great influence on the production and application of plastic fats, and the taste, fragrance and spreadability of products, etc. have a great impact. [0003] As far as the current technical level is concerned, in order to meet the requirements of specific so...
