Problems solved by technology

Due to the destruction of the gluten network structure, the air-holding performance of the dough is reduced, and the activity of the yeast is reduced, which makes the proofing time longer, and the volume of the bread after proofing decreases, and the dough shrinks.

Abstract

The invention discloses a frozen potato steamed bun added with an antifreeze sericin peptide. The raw material of the frozen potato steamed bun comprises the following ingredients in parts by weight: 20-40 parts of wheat meal, 20-40 parts of potato powder, 4-8 parts of sericin peptide, 0-5 parts of sugar, 0-2 parts of salt, 1-2 parts of yeast, 3-5 parts of vital gluten, 0.5-1 part of carrageenan, 1-2 parts of xanthan gum and 15-30 parts of water. The invention also provides a preparation method for the frozen potato steamed bun. According to the invention, the antifreeze sericin peptide and the potato powder are added into the frozen steamed bun, so that the steamed bun not only has the healthcare functions of regulating cholesterol, preventing fat deposition of cardiovascular system, preventing atherosclerosis, maintaining beauty and keeping young but also has excellent appearance, fluffy and fine taste and special strong fragrance, and the water retention capacity, air permeability and freezing thawing property of the frozen steamed bun and the freezing storage resistance of the yeast are improved.

Description

technical field [0001] The invention relates to a potato frozen steamed bun and a manufacturing method thereof, in particular to a potato frozen steamed bun added with sericin antifreeze peptide and a manufacturing method thereof. Background technique [0002] Pasta refers to food mainly made of flour. There are different types of pasta all over the world. In China, there are mainly: noodles, steamed buns, sesame seed cakes, dumplings, buns, etc. In the West, there are bread, various scones, etc., and there are many types.
