preparation example

[0073] According to the formula shown in Table 1, mix the fat and oil according to the mass ratio (control the fat FFA% within 0.1wt%), first dehydrate under vacuum conditions at 105°C for 30min (control the moisture within 0.05wt%), then add the catalyst sodium methoxide, The dosage is 0.2-0.3% of the weight of the fat, and the reaction temperature is 105-110°C for 30-40 minutes, and the vacuum condition is 0.1bar minimum. Then a 10% concentration of citric acid solution was added to terminate the reaction, and the amount converted into citric acid was twice the amount of sodium methoxide. Then it is washed with water until it is neutral, dehydrated, decolorized, and refined for use.

[0074] Refer to the AOCS cd 16b-93 method to detect the solid fat content of the prepared transesterified grease, namely SFC (solid fat content of plastic fat at a certain temperature). The specific detection method is as follows:

[0075] Take 1.5-2mL of the sample to be tested (if it is a non-liq...

Embodiment

[0088] The transesterification product prepared in the preparation example was stirred in a water bath of an ice-water mixture to crystallize and harden, and then the hardened fat was aged for 12 hours at a refrigerator temperature to prepare margarine for evaluation.

[0089] 1. Crystallization rate test:

[0090] Crystallization rate test method: Keep the grease sample at 60℃ for 30 minutes, and then test the solid fat content after 2min, 4min, 6min, 8min, and 10min in a water bath at 10℃, which is the amount of crystallization, and then divide it by 10 SFC value at ℃, get the crystallization rate.

[0091] The results are shown in Table 4 and figure 1 Shown.

Abstract

The invention provides a fat composition high in crystallization rate but gentle in SFC curve. The fat composition is a random transesterification fat composition of shea butter liquid fractionation components and palm oil fractionation components. For the fat product prepared from the fat composition, the problems of oil seeping and after hardening are greatly solved.

Description

Technical field [0001] The present invention relates to a fat composition with a fast crystallization rate but a gentle SFC curve. Background technique [0002] Generally, it is necessary to obtain a fat product with a faster crystallization rate. Generally, the solid fat curve is required to be very steep or the melting point is very high. When this type of fat is used as the base oil of the special fat product, it will bring the fat and brittle, hard after Product quality problems such as oil leakage. It is generally believed that oils with a faster crystallization rate and a gentle solid fat curve or a low melting point are contradictory, and it is difficult to have both. [0003] Shea olein is a liquid or semi-solid fat product obtained from shea butter as a raw material through fractionation and other processes. The shea butter is a natural light yellow semi-solid oil extracted from African shea butter. Shea butter can effectively prevent solar dermatitis and has anti-aging...
