Description

Baking-resistant high-oil custard sauce and preparation method and application thereof
Technical Field
The invention relates to the technical field of food processing, and particularly discloses baking-resistant high-oil custard sauce as well as a preparation method and application thereof.
Background
Custard is a transliterated foreign word that comes from the Custard transliteration and plays an important role in western style baking and catering, for filling and surface decoration of bread and puffs, for enriching the taste of baked products and for enhancing mouthfeel. Custard sauce (custard cream), also known as custard, is a requisite material for fabricated desserts and cookies. The traditional custard sauce is mainly prepared by mixing egg and milk with a heated and matured egg-milk mixture, and is part of a French meal. In the middle ages, it has been common practice to place the egg-milk mixture in a pastry and to bake out the dessert.
Due to its rich mouthfeel and unique properties, custard sauce finds increasing use in baked products. However, the existing custard sauce is easy to separate out water, oil and age to harden after being placed for a long time. Due to the combination of egg and milk, microorganisms are easy to breed in the storage process of the custard sauce, the shelf life of the custard sauce is short, and the application requirements of modern industrialized baked products cannot be met.
Patent CN 106107911a discloses a cassidata sauce added with modified starch, which is prepared from the following raw materials in parts by weight: 36-50 parts of water, 15-18 parts of white granulated sugar, 10-12 parts of fresh egg yolk, 6-8 parts of whole milk powder, 8-10 parts of high fructose corn syrup, 6-8 parts of butter, 5-8 parts of hydroxypropyl waxy corn modified starch, 0.1-0.2 part of fatty acid ester emulsifier, 0.1-0.2 part of acidity regulator and 0.1-0.2 part of preservative. The custard sauce not only has fine and smooth mouthfeel and attractive appearance, but also has the properties of long shelf life, high-temperature boiling resistance and mechanical shearing resistance, and has good freeze-thaw stability. However, the Kashida soy sauce of the above patent has a low fat content, is relatively burnt, has poor baking resistance, and has a certain loss of taste.

Table 2 shows the evaluation results of the emulsion stability during the standing time of 0 day, 5 days, 12 days, 21 days, 35 days for the kashida pastes obtained in examples 1 to 3 and comparative examples 1 to 3. Table 3 shows the results of the baking resistance test of the kashida pastes prepared in examples 1 to 3 and comparative examples 1 to 3 after being baked at 200 c for 10 min.
The Kashida soy sauce in the prior art has low fat content, and meanwhile, the fat is easy to separate out in the cooking process, so that the taste and the state of the product are influenced. The baking-resistant high-oil custard sauce disclosed by the invention is mainly characterized in that water and oil form a stable emulsification system through the synergistic effect of milk powder, whey protein, microcrystalline cellulose, sodium alginate and carrageenan and the emulsification effect of a homogenizer, so that the emulsified slurry does not separate oil in the high-temperature cooking process. The unique oil-in-water emulsifying system does not separate oil in the long-term storage of the product, and can endow the cassoda sauce with the straightness and texture to achieve the baking resistance.
Particularly, the synergistic effect of the whey protein, the microcrystalline cellulose, the sodium alginate and the carrageenan in the formula is mainly that the milk powder and the whey protein both contain rich milk protein, and the milk protein has good emulsifying property. The microcrystalline cellulose is natural cellulose, can form a stable dispersion system under the action of homogenization, and forms a creamy suspension with grease and milk protein, thereby ensuring the emulsification and high-temperature stability. Meanwhile, the sodium alginate and the carrageenan can increase the consistency of the slurry, ensure the stability of an emulsification system and cooperatively ensure the baking resistance of the Kashida sauce.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, therefore, the present invention is not limited by the appended claims.
