Description

Preparation method of steamed bread rich in Omega-3 fatty acid
Technical Field
The invention belongs to the technical field of food, and particularly relates to a preparation method of steamed bread rich in Omega-3 fatty acid.
Background
Omega-3 fatty acids are called "essential" fatty acids because they cannot be produced by the human body and must be provided by the diet to ensure a healthy need. The source of Omega-3 fatty acids is limited. Unlike other fatty acids that are widely found in food products, these Omega-3 fatty acids are found primarily in fish, certain vegetables and nuts that are rich in fat. Functionally, omega-3 fatty acids can have a wide range of effects on cell function. In addition to being an energy source, these fatty acids are important factors in determining the physicochemical properties of cell membranes, and also serve as substrates for the production of signaling molecules or functional mediators and as regulators of gene expression. Thus, omega-3 fatty acids can profoundly affect physiological activities and pathological processes through a variety of mechanisms.
Research reports indicate that the fat intake in the daily diet of Chinese residents is in a rapid increasing trend, but the intake proportion of saturated fatty acids is increased, the intake proportion of polyunsaturated fatty acids is reduced, and the intake proportion of Omega-3 polyunsaturated fatty acids is always lower. At present, the proportion of cholesterol obtained from the daily diet of Chinese people is higher and higher, the incidence rates of various chronic diseases and cardiovascular and cerebrovascular diseases are increased year by year, and the lack of Omega-3 fatty acid for a long time causes insufficient prevention of the health hidden troubles, which is worried about.
The steamed bread is a staple food which is widely popular with people in China, but the steamed bread prepared by using commercial yeast belongs to pure yeast fermentation, and the steamed bread contains a single enzyme system and has a relatively mediocre taste. The traditional sour dough steamed bun has excellent flavor, but the system flora composition is complex, the fermentation process is not easy to control, the product quality is unstable, the temperature and the climate and different flavors of operators have great fluctuation, and various problems such as exogenous mixed bacteria pollution and the like exist, so that the industrial production is difficult, and the taste of the old steamed bun remained in the memory is difficult to reproduce.
Although the steamed bread is a popular staple food, the main ingredients of the steamed bread are delicate carbohydrate, the nutrition is too single, the satiety is not strong, and the mouthfeel is more moderate and less popular with young people.
Disclosure of Invention
In order to solve the problems, the invention develops the steamed bread which is excellent in flavor, rich in Omega-3 fatty acid and has satiety by adding sour dough to improve the flavor of the steamed bread and combining the addition of nut seeds rich in Omega-3 and oil raw materials.
The first purpose of the invention is to provide a preparation method of steamed bread rich in Omega-3 fatty acid, which comprises the following steps:
s1, mixing lactobacillus plantarum, lactobacillus rhamnosus and active dry yeast powder with water and flour, kneading uniformly, and performing primary fermentation to obtain fermented sour dough;
s2, mixing and stir-frying flaxseed, chia seed, sesame and walnut kernel, adding high fructose corn syrup, and uniformly mixing;
and S3, adding hot water into the fermented sour dough, stirring to form a paste, adding flour and active dry yeast powder into the paste, kneading until the flour and the active dry yeast powder are smooth to obtain a cake, smearing linseed oil on the surface of the cake, dispersing the mixture obtained in the S2 on the cake, performing secondary fermentation, and steaming to obtain the steamed bread rich in Omega-3 fatty acid.
Furthermore, the viable count of the lactobacillus plantarum is not less than 3000 hundred million CFU/g.
Furthermore, the viable count of the lactobacillus rhamnosus is not less than 1000 hundred million CFU/g.
Further, in the step S1, the mass ratio of the lactobacillus plantarum to the lactobacillus rhamnosus to the active dry yeast powder to the water to the flour is 0.2 to 0.4.
Further, the primary fermentation is carried out for 7-10 h at 30-39 ℃ and 70-80% humidity.
Further, the active dry yeast powder is Angel active dry yeast.
Further, the hot water is water with the temperature of 35-40 ℃.
Further, the secondary fermentation is carried out for 30-60 min at 30-39 ℃ and 70-80% humidity.
Further, the mass ratio of the flaxseed, the chia seed, the sesame, the walnut kernel and the high fructose corn syrup is (3-4).
The second purpose of the invention is to provide the steamed bread rich in Omega-3 fatty acid prepared by the preparation method.
The invention has the beneficial effects that:
the traditional yeast steamed bun has a relatively moderate flavor, and the steamed bun provided by the invention is obviously different from the common yeast steamed bun in taste due to the addition of the sour dough, and has a unique old yeast flavor. Meanwhile, the invention solves the problems of weak satiety and single nutrition of the conventional steamed bread on the basis of improving the flavor of the steamed bread by screening fermentation strains and optimizing raw materials, and improves the intake of Omega-3 fatty acid.
