Problems solved by technology

The preparation of the second type of oil gel generally adopts two distinct methods according to the properties of the gelling agent (such as EC, HPMC, etc.): one method is to mix the polymer, the surfactant and the oil, The high polymer is melted, and then the temperature is lowered to precipitate and form a self-assembled network. The temperature of the oil phase in this method is much higher than that of the first type, so it may bring risks to the quality of the oil during processing
The preparation process of this oil gel does not involve the use of high temperature and additives, and the preparation process is relatively simple, but the preparation steps of the gel are relatively cumbersome

Embodiment 1

[0034] (1) Preparation of L-ascorbyl palmitate ethanol solution: fully dissolve L-ascorbyl palmitate accounting for 4% of the mass fraction of the final baked oil into ethanol according to the solubility of 1 g in 4.5 ml of ethanol;

[0035] (2) Mix the sample: the L-ascorbyl palmitate ethanol solution obtained in step (1) is mixed with sunflower oil for subsequent use;

[0036] (3) Formation of the gel network: the sample mixed solution obtained in step (2) was rotated at 55° C. for 0.5 h to remove ethanol and form a gel oil network at the same time;

[0037](4) Aging: Place the sample obtained in step (3) at 20°C and let it stand for 24 hours to obtain L-ascorbyl palmitate-based baking oil, and place the L-ascorbyl palmitate-based baking oil at 3-5°C Store in the refrigerator.

Embodiment 2

[0039] (1) Preparation of L-ascorbyl palmitate ethanol solution: fully dissolve L-ascorbyl palmitate accounting for 6% of the mass fraction of baked oil into ethanol according to the solubility of 1 g in 4.5 ml of ethanol;

[0040] (2) Mix the sample: the L-ascorbyl palmitate ethanol solution obtained in step (1) is mixed with sunflower oil for subsequent use;

[0041] (3) Formation of the gel network: the sample mixed solution obtained in step (2) was rotated at 55° C. for 0.5 h to remove ethanol and form a gel oil network at the same time;

[0042] (4) Aging: Place the sample obtained in step (3) at 20°C and let it stand for 24 hours to obtain L-ascorbyl palmitate-based baking oil, and place the L-ascorbyl palmitate-based baking oil at 3-5°C Store in the refrigerator.

Embodiment 3

[0044] (1) Preparation of L-ascorbyl palmitate ethanol solution: fully dissolve L-ascorbyl palmitate accounting for 8% of the mass fraction of baked oil into ethanol according to the solubility of 1 g in 4.5 ml of ethanol;

[0045] (2) Mix the sample: the L-ascorbyl palmitate ethanol solution obtained in step (1) is mixed with sunflower oil for subsequent use;

[0046] (3) Formation of the gel network: the sample mixed solution obtained in step (2) was rotated at 55° C. for 0.5 h to remove ethanol and form a gel oil network at the same time;

[0047] (4) Aging: Place the sample obtained in step (3) at 20°C and let it stand for 24 hours to obtain L-ascorbyl palmitate-based baking oil, and place the L-ascorbyl palmitate-based baking oil at 3-5°C Store in the refrigerator.

Abstract

The invention discloses an L-ascorbyl palmitate-based baking oil and a preparation method thereof, belonging to the field of baking oil production. The present invention uses high oleic acid sunflower seeds as base oil, and adds L-ascorbyl palmitate to construct a gel network, firstly dissolves L-ascorbyl palmitate in ethanol, and then adds high oleic acid sunflower seeds In oils, gel oil networks can be formed at lower temperatures. While reducing trans-fatty acids and unsaturated fatty acids, it can bring nutrition and health to consumers, and the method of the invention can save energy and reduce costs.

Description

technical field [0001] The invention relates to an L-ascorbyl palmitate-based baking oil and a preparation method thereof, in particular to a preparation method of a healthy baking oil without trans fatty acid, belonging to the field of baking oil production. Background technique [0002] Ghee is transformed from the English word "shorten", which means that biscuits, etc. are processed with this kind of fat, which can make the product very crispy, so the fat with this property is called "shortening". Traditional "shortening" is a solid oil made from refined animal and vegetable oils, hydrogenated oils, or a mixture of the above oils, quenched and kneaded, and the trans acid content can be as high as 20%-40%, and its trans fatty acid content is seriously exceeded. . More and more studies have shown that intake of high levels of trans and saturated fats can lead to metabolic syndrome and cardiovascular diseases, causing harm to people's health. With consumers' demand for hea...
