The present invention discloses a multi-
fermentation-coupled pastry and a
processing method thereof. A formula comprises
aspergillus niger, flour, sweet potatoes, taros,
rhizopus, a
fermentation agent, Chinese yams, eggs, white granulated
sugar and fermented flour sweet sauce. The
mass percentages of each component are respectively as follows: 15-25% of
aspergillus niger, 10-20% of flour, 2-4% ofsweet potatoes, 10-20% of taros, 25-35% of
rhizopus, 15-25% of a
fermentation agent, 1-3% of Chinese yams, 5-10% of eggs, 0.5-1% of white granulated
sugar and 0.5-1% of fermented flour sweet sauce. The
processing method comprises the followings steps: step one,
raw material selecting; step two, edible material
processing; step three, fermentation
coupling; step four, pastry shaping; and step five,boxing and storing. The processing method is safe and reliable and uses the
aspergillus niger,
rhizopus and fermentation agent as the fermentation raw materials, multi-fermentation-coupled fermentation is conducted under vacuum conditions, traditional simple fermentation-agent fermentation is abandoned, the processing method is more conducive to pastry fermentation and processing, so that the pastry is more fluffy,
mouthfeel of the pastry is greatly improved, and the pastry is simple and rigorous, the raw materials are cheap and low in cost, and production cost is greatly saved.
