Fermented product of red yeast rice linseed cake and application thereof

Abstract

The invention discloses a red yeast linseed meal fermented product and its application, and belongs to the technical field of food processing. A monascus flax meal fermented product is prepared according to the following steps: (1) primary detoxification of the flaxseed meal: controlling the moisture content of the flaxseed meal to 170-200 g / kg, and detoxifying by 800W microwave for 8 minutes; (2) ) Flaxseed meal fermentation and further detoxification: activate Monascus slant for 3 to 4 times, insert into the seed medium, cultivate at 30°C for 3 days, then insert 10% of the inoculum into the fermentation medium, and culture at 30°C 5-7d, after the fermentation is completed, the fermentation broth is concentrated. The invention can not only improve the economic added value of flaxseeds, but also generate huge economic and social benefits.

Description

technical field

[0001] The invention belongs to the technical field of food processing and relates to functional food, in particular to a fermented red yeast rice linseed cake and an application thereof. Background technique

[0002] Red yeast rice was first discovered in China and has a production and application history of more than one thousand years. Its fermentation product contains lovastatin K (Monacolin K), which has the physiological activity of lowering blood pressure, blood sugar and cholesterol. Traditional red yeast rice is mainly used in the fields of food processing technology such as brewing rice wine, making fermented bean curd, edible ester, food coloring and so on.

[0003] Flaxseed meal is a by-product of deoiling linseed, which has less fat content than linseed, is rich in protein, crude fiber, lignans, linseed gum and other components, and contains cyanogenic glycosides. Among them, lignans have strong antioxidant activity. As phytoestrogens, they have...

[0038] Example 2 The preparation of the fermented product of red yeast rice linseed cake, the steps are:

[0039](1) Adjust the water content of flaxseed cake to 170-200 g / kg, and detoxify it by 800W microwave for 8 minutes;

[0040] (2) To make red yeast rice linseed cake medium, the formula is: 1000 g of linseed cake after microwave detoxification, 300 g of corn flour, NaNO 3 20 g, MgSO 4 ·7H 2 O 10 g, KH 2 PO 4 10 g, ZnSO 4 ·7H 2 O 20 g, distilled water 10L, pH4.5.

[0041] (3) After activating the slant of Monascus purpureus ATCC5046 for 3 to 4 times, insert the seed fermentation broth at 30°C for constant temperature cultivation for 3 days, and then insert 10% of the inoculum into the Monascus purpureus flax cake medium at 30°C, The stirring speed was 100 r / min, the ventilation rate was 1:4, and the fermentation was carried out for 5 to 7 days. The red pigment color value of the supernatant of the fermentation liquid was measured to be above 800 u / mL, and the ferme...

[0044] The preparation of red yeast flax biscuits, the steps are:

[0045] (1) Accurately weigh the following components: 2.0 Kg of fermented red yeast rice flax cake, 7.0 Kg of wheat flour, 1.5 Kg of eggs, 1.0 Kg of white sugar, 2.0 Kg of linseed oil, 0.05 Kg of edible salt, 0.03 Kg of ammonium bicarbonate, Baking soda 0.03 Kg, water 1.0 Kg;

[0046] (2) Mix eggs and linseed oil and stir well to make an oil solution, set aside;

[0047] (3) Dissolve white sugar, edible salt, ammonium bicarbonate, and baking soda in water to make an aqueous solution for later use;

[0048] (4) Add the fermented product of red yeast rice flax cake and wheat flour to the above oil solution and aqueous solution, stir evenly to form a dough, let the dough stand for 40 minutes, and roll it into a biscuit base with a thickness of 0.5cm according to the need. Evenly coat the bottom with a layer of vegetable oil and transfer to a baking tray, preheat the oven at 150°C for 20 minutes, bake the biscui...
