Problems solved by technology

However, this technology has the following defects: (1) SEE contains trans-acid, and clinical trials and epidemiological studies have shown that trans-acid is a fat harmful to human health. For the consideration of public health, it should be reduced as much as possible Content of trans acid; (2)S 1 MS 2 and MS 3 Saturated fatty acids account for half of M, and S 1 MS 2 It is a symmetrical oil. Half of this kind of symmetrical oil comes from rare raw material oils such as cocoa butter and cocoa butter, and the resources are scarce.

preparation example Construction

[0058] The second aspect of the present invention provides a method for preparing an oil composition, said method including the step of mixing oil and fat raw materials.

[0059] In a preferred example of the present invention, the oil and fat raw materials include oil A with an SSU content of more than 51 wt% and oil B with a UUS content of more than 70 wt%.

[0060] In the present invention, fats A and B may both be animal and vegetable fats, one of them may be obtained by compounding triglyceride monomers, and both may be obtained by compounding triglyceride monomers.

[0061] In another preferred example of the present invention, the fat A is one or more of lard, tallow, fish oil, and chicken and duck fat, and the fat B is palm oil, soybean oil, rapeseed oil, corn oil, sesame oil , cottonseed oil, coconut oil in one or more.

[0062] In another preferred example of the present invention, the oil raw material is compounded from triglyceride monomers; preferably, the trigly...

Embodiment 1

[0122] Embodiment 1: take natural oil as raw material to prepare oil products

[0123] 15wt% 1,2-stearic acid-3-arachidic acid glyceride, 50wt% 1-palmitic acid-2-stearic acid-3-oleic acid glyceride, 35wt% 1-stearic acid-2-oleic acid -3-Glyceryl linolenate is sent into the mixing tank to obtain oil A1; %1,2-palmitoleic acid-3-palmitin glyceric acid ester is sent into the mixing tank to obtain oil B1.

[0124] After the raw materials shown in Table 2 are sent into the mixing tank, they are stirred and mixed (stirred at 140-180rpm for 30 minutes), then sent to the quencher for conventional quenching treatment (cooling at a rate of 7°C / min for 3 minutes), and then sent to the kneader Perform conventional kneading treatment (kneading treatment at a rotational speed of 100-120 rpm for 3 minutes), and finally conventional aging treatment (aging at a temperature of 20° C. for 3 days) to prepare plastic oil products a~d.

Embodiment 2

[0128] Embodiment 2: Preparation of oil products with compound oil as raw material

[0129] Send the mixing tank according to the raw materials shown in Table 3 and mix to obtain the required grease A and grease B, for example, 5wt% PPP (tripalmitin), 55wt% SSO (1,2-stearic acid-3- Glyceryl oleate), 40wt% SOO (1,2-oleic acid-3-stearic acid glyceride) are sent into the mixing tank and mixed to obtain the grease A in embodiment g. The oil and fat raw materials in other embodiments are compounded according to this method.

[0130] After the fats A and B of compounding gained are sent into the blending tank according to the consumption shown in Table 2, they are stirred and mixed (stirring at 140-180rpm for 25-35min), and then sent into the quenching machine for conventional quenching treatment (with 5-10 ℃ / min rate of cooling for 3-7 minutes), then sent to the kneader for conventional kneading treatment (3-5 minutes of kneading treatment at a speed of 100-120 rpm), and finally c...

Abstract

The invention provides a grease composition. The grease composition comprises, based on the weight of total triglycerides, more than 25.5 wt% of 1,2-disaturated-3-unsaturated triglyceride (SSU), more than 33.1% of 1,2-diunsaturated-3-saturated triglyceride (UUS), more than 9.2 wt% of trisaturated triglyceride (SSS), and less than 10 wt% of triunsaturated triglyceride (UUU), wherein the S is saturated fatty acid and the U is unsaturated fatty acid. The invention also provides a preparation method of a plastic grease product. The method includes subjecting the grease composition to rapid cooling, kneading and curing processing. The plastic grease product prepared by the method has advantages of wide plasticity temperature range, high crystallization rate, high expansion rate, and the like.

Description

technical field [0001] The invention relates to the field of oil compositions, in particular to an oil composition capable of producing oil products with fast crystallization rate, wide plastic range and high expansion rate. Background technique [0002] Food-specific fats and oils that are used for baking bread, cakes, biscuits, cookies, pies, fried donuts, etc. are called baking fats. Fat plays a pivotal role in bakery products, it has a very unique function in bakery products, and the final flavor effect of baked food with baked fat and ordinary fat is not the same, which depends on its unique functions such as Plasticity, caseinization, shortening, stability, frying, emulsification, water absorption, etc. Therefore, with the continuous development of the baking industry, the demand for baking oil is also increasing. [0003] Our country has a vast territory, and the large span between the north and the south makes the temperature difference between the north and the so...
