Embodiment 1

[0042] This embodiment prepares a kind of anti-aging prebaked bread containing hydrophilic colloid and collagen antifreeze polypeptide, based on the total weight of the prebaked bread dough, the consumption of each component of the prebaked bread is: all-purpose flour: 49wt%, Night species: 14.75wt%, sodium chloride: 1.5wt%, yeast: 1wt%, squash gum: 0.2wt%, glutamine transaminase: 0.05wt%, money fish skin antifreeze polypeptide powder: 3wt%, the rest The amount is water.

[0043] The night seed is obtained by fermenting 500g of water+500g of high-gluten flour+2g of commercially available low-sugar yeast.

[0044] Among them, the preparation method of the antifreeze polypeptide powder of money fish skin includes: crushing and homogenizing the collected money fish skin to get the suspension, and enzymolyzing the protein with alkaline protease with a pH of 9, and then centrifuging at 10000r / min , followed by 20, 10 and 5kDa ultrafiltration membrane ultrafiltration, retaining the...

Embodiment 2

[0048] Different from Example 1 in that:

[0049] Based on the total weight of the pre-baked bread dough, the amount of each component of the pre-baked bread is: all-purpose flour: 50wt%, night seed: 16wt%, sodium chloride: 1.9wt%, yeast: 0.8wt%, sage Glue: 0.2wt%, transglutaminase: 0.1wt%, money fish skin antifreeze polypeptide powder: 1wt%, the balance is water. The final fermentation of the dough is assisted by ultrasonic at 440W, and the pre-baked bread obtained is S-2.

Embodiment 3

[0051] Different from Example 1 in that:

[0052] Based on the total weight of the pre-baked bread dough, the amount of each component of the pre-baked bread is: all-purpose flour: 49wt%, night seed: 14.9wt%, sodium chloride: 1.95wt%, yeast: 1wt%, sage Glue: 0.05wt%, transglutaminase: 0.1wt%, money fish skin antifreeze polypeptide powder: 3wt%, the balance is water. The final proofing of the dough is ultrasonically assisted at 460W, and the pre-baked bread obtained is S-3.

Abstract

The invention discloses anti-aging pre-baking bread containing hydrophilic colloid and collagen anti-freezing polypeptide and a preparation method thereof. The preparation method comprises the following steps: (1) activating glutamine transaminase and yeast in a constant temperature; (2) uniformly mixing plain flour, sesbania gum and scatophagus argus fishskin anti-freezing polypeptide powder; (3)enabling a night seed to be mixed with a mixture obtained in the step (2) and water, stirring and beating; (4) adding sodium chloride, glutamine transaminase water solution and yeast water solution,stirring and beating, to obtain dough; (5) after first-stewing, exhausting, loosening and second-stewing, dividing and slicing or shaping to a designated shape; (6) fermenting; (7) baking, to obtain the bread; and (8) after quick-freezing the baked bread in the step (7), refrigerating. The preparation method is capable of reducing mechanical damage to the pre-baking bread by ice crystals, therebyincreasing ageing resistance of the bread on the one hand; and increasing stability of a self-network structure of gluten on the other hand, and improving strength of the gluten.

Description

technical field [0001] The invention belongs to the field of food processing, and more specifically relates to an anti-aging prebaked bread containing hydrocolloid and collagen antifreeze polypeptide and a preparation method thereof. Background technique [0002] The noodle industry usually uses chemically synthesized gluten-strengthening agents such as ADA to improve the network structure of gluten protein, but excessive consumption of ADA will cause certain harm to the human body. Studies have shown that long-term exposure to ADA in occupational groups can cause respiratory symptoms, dermatitis and asthma. ADA is used as an additive in flour products, and its metabolites in the human body have two toxic substances, semicarbazide and ethyl carbamate. Among them, semicarbazide may have mutagenicity and carcinogenicity to the human body, and ethyl carbamate has It may have a carcinogenic effect on the human body. For the people in northern my country who have been eating past...
