Problems solved by technology

However, Non-Patent Document 1 states that if fresh yeast is frozen, a part of the yeast will die and the fermentation ability will be weakened, so it is wise not to freeze fresh yeast
[0007] Granular frozen yeast is described in Patent Document 1, but it is only a material obtained by freezing dry yeast or semi-dry yeast with a dry matter content of 70 to 85%, and the ability to decompose granulated sugar is insufficient as described above. There is a problem that the fermentation ability is low

Embodiment 1~9 and comparative example 1~3

[0075] First, a mold for producing a molded body having the shapes, dimensions and linear grooves shown in Table 1 was prepared. The positions of the grooves are determined in such a manner that the areas of the regions divided by the grooves are the same as each other.

[0076] The fresh pressed yeast manufactured by KANEKA with a dry weight of 32% was weighed in a polyethylene bag, and it was put into the mold in a bagged state, and compression-molded with a hand press to obtain the bagged state A fresh yeast shaped body having the shapes, dimensions and grooves shown in Table 1. After molding, the fresh yeast molded body was taken out from the bag, and the following evaluations regarding long-term storage properties were performed. The dry matter weight of this fresh yeast shaped body is 32.3%.

[0077] Next, the shaped fresh yeast was frozen in an air-cooled freezer at -20° C. for two months, while being bagged, to obtain a frozen fresh shaped yeast in a bag.

Embodiment 10、11 and comparative example 5、6

[0082] Using dry matter weight is 19.2~42.3% KANEKA makes pressed fresh yeast, is the same as embodiment 1, according to the shape shown in table 1, size and groove and obtain the frozen fresh yeast molded body that puts into the bag.

Abstract

A frozen fresh yeast molded body in which live yeast has been frozen. The molded body has an approximately plate-shaped form comprising a first surface and a second surface opposing the first surface.At least one line-shaped groove is formed on the first surface, and the thickness of the molded body from the deepest part of the groove to the second surface is in the range of 1-12 mm. The yeast content, as dry weight, is 25-40 mass% with respect to the total mass of the frozen live yeast molded body, and the water content is 60-75 mass%.

Description

technical field [0001] The invention relates to a frozen fresh yeast molded body obtained by freezing fresh yeast and a manufacturing method thereof. Background technique [0002] In recent years, in the bread manufacturing industry, unskilled operators have increased due to the flow and internationalization of human resources, and cost competition has intensified. Therefore, it is desired to simplify and improve the efficiency of the bread manufacturing process. [0003] The distribution forms of bread-making yeast are roughly divided into fresh yeast, dry yeast, and semi-dry yeast. Fresh yeast, also known as pressed yeast, is sold in cubes or powder. Compared with dry yeast or semi-dry yeast, this type of fresh yeast has a stronger ability to decompose granulated sugar, and supports features such as good flavor and high fermentation ability, and is the most widely distributed in the market. [0004] However, fresh yeast has weak tolerance to dryness and temperature chang...
