The low-saturation liquid grease loses the support of a large amount of solid fat, so that the key indexes such as plasticity, hardness and the like are seriously reduced, and the requirements of many food applications such as baking and the like cannot be met. In order to achieve the application effect of solid fat, the texture of the liquid fat must be enhanced, besides the solidification of the liquid oil by means of the crystal clusters, the embedding layers or the network structure formed by the gel, the liquid fat can be solidified by oil-based adjustment while keeping the lower saturation degree of the liquid fat, so that the baking requirement is met.
There remains a need in the art for grease compositions that achieve low saturation while meeting the baking needs through oil-based conditioning.

Example eight determination of bread appearance State (height, aspect ratio and capacitance ratio)
The height, width (diameter) and mass of the bread and steamed bread were measured by a volumetric measuring device, and the ratio of height to diameter and the ratio of volume to mass were calculated, and the results are shown in Table 7.
Example nine bread texture determination
The prepared bread samples were first cut into 10mm thick slices using a bread slicer, after which the TPA test was performed under the following conditions:
probe: P/36R type cylindrical flat bottom probe; speed before test: 1.0mm/s; test speed: 5.0mm/s; post test speed: 5.0mm/s, the probe is pressed down by 10.00mm after sensing 5.0g force.
The appearance state (height, aspect ratio, and texture ratio) and texture measurement results of the bread are shown in table 7 below.
TABLE 7 appearance state and texture of bread
Figure BDA0003439898320000121
As is clear from the results shown in Table 7, the breads prepared in examples 1 to 5 were not significantly different in appearance and texture from those of comparative examples 4 to 5 (general baked fats), i.e., the various baked fats prepared from the fat composition of the invention were not significantly affected in appearance and texture of the breads, but had low saturation characteristics.
Example ten, dough whipping time
In the bread preparation (dough kneading process), the time required from the addition of the fat to the formation of gluten, i.e., the dough whipping time, was recorded separately, and the results are shown in table 8.
Table 8 dough whipping time in bread preparation
Examples/comparative examples Dough whipping time/min after adding fat
Example 1 3.5
Example 2 3.3
Example 3 3.4
Example 4 3.4
Example 5 3.3
Comparative example 1 5.7
Comparative example 2 5.4
Comparative example 3 5.6
Comparative example 4 3.4
Comparative example 5 3.5
As is clear from the results shown in Table 8, in the bread baking, the baked fats and oils of examples 1 to 5 are capable of significantly shortening the whipping time of the dough, that is, the various types of baked fats and oils prepared from the fat and oil compositions 1 to 5 of the present invention, as compared with comparative examples 1 to 3, and in the bread baking, the whipping time of the dough is effectively shortened, and the dough whipping time is close to that of comparative examples 4 to 5 (general baked fats and oils), but has a low saturation characteristic.
In conclusion, the oil and fat composition has low saturation of 25-32%, is solid at room temperature, and can increase the crispness of biscuits and obviously reduce the oil separation rate of the biscuits in the storage process in biscuit baking, and can obviously shorten the forming time of dough in bread baking, thereby reducing the operation cost.
