Problems solved by technology

Although this fresh-keeping method can achieve a certain fresh-keeping effect, it needs to be equipped with inflatable equipment and an inflatable process, which is time-consuming, laborious, and costly
The second method is to freeze or store the steamed buns at low temperature. Usually, quick-freezing technology is used to store, transport and sell the steamed buns in a frozen state (the central temperature of the product is below minus 18 degrees Celsius). Although this method can effectively preserve freshness, its The cost is much higher than normal temperature storage
The fresh-keeping steamed buns obtained by the above three methods can keep fresh at room temperature for up to 60 days, and the fresh-keeping period is shorter
[0003] In addition, most of the steamed steamed buns currently use dry yeast or yeast for fermentation. After kneading the dough once, the dough is proofed for 60 minutes for molding, which takes a short time. Some methods use old dough to ferment, and most The methods all use alkali, and the fresh-keeping effect of the steamed buns fermented by these methods is poor, and the fresh-keeping period is short

Abstract

The invention discloses a preparation method for fresh-keeping steamed breads, which particularly comprises the following continuously performed steps: preparing leaven, kneading leaven, kneading leaven and dough, mixing dough, shaping, fermenting and steaming. A yeast is fermented for 4-6 times by using a culture medium so as to obtain the leaven; in a room with the natural temperature, the steaming temperature is 97-100 DEG C, when the centers of the steamed breads are heated over 97 DEG C and the temperature is kept for more than 30 minutes, the steamed breads are prepared; the fresh-keeping package, inspection, observation and storage of the steamed breads are performed in an online manner. According to the preparation method, the leaven is obtained via fermentation for 4-6 times to ferment the dough, adding any anticorrosive is needless, and gas exchange during package is needless. After inspection, the fresh-keeping period of the steamed breads prepared by adopting the method can reach 90 days at the normal temperature.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a method for making fresh-keeping steamed buns. Background technique [0002] Fresh-keeping steamed buns are popular in the fast-paced life of people in today's society because of their convenience. The production methods of fresh-keeping steamed buns are roughly divided into three methods.
