A temperature-fluctuating oil composition and its preparation method

Abstract

A grease composition is provided. In the grease composition, the content of SSS is 10-20 wt%, the content of PPP is 0-10 wt%, the content of POO is 8-18 wt%, the content of POP is 10-15 wt%, and POP / POSt is not more than 2 and not less than 1. A preparing method of the grease composition is also provided. The method includes subjecting grease A containing shea butter and grease B containing palm oil to interesterification. The mass ratio of the grease A to the grease B is 0.1-10:1. The grease A is a mixture of the shea butter and one or more selected from soybean oil, hydrogenated soybean oil, palm olein and hydrogenated palm olein. The grease B is a mixture of the palm oil and one or more selected from beef tallow, hydrogenated beef tallow, fish oil and hydrogenated fish oil. Margarine prepared from the grease composition is advantaged by good resistance to temperature fluctuation and the like.

Description

technical field

[0001] The invention relates to the field of oil composition, in particular to a temperature fluctuation-resistant oil composition and a preparation method thereof. Background technique

[0002] With the increasing development of the baking market, plastic oil products such as margarine and shortening are widely used. More and more formulations of plastic oils (for example: shortening, margarine) on the market are made with vegetable oil bases, especially the formulations containing palm oil bases are widely used. However, there is a significant shortcoming in the palm oil-based baking oil formula, which is poor in resistance to temperature fluctuations, and is prone to a significant increase in hardness under the condition of temperature fluctuations in alternating seasons, which seriously restricts the promotion of baking oils containing palm oil formula.

[0003] Aiming at the problem that palm oil-based margarine is not resistant to fluctuations, some oi...
