Problems solved by technology

However, it is described in Non-Patent Document 1 that if fresh yeast is frozen, part of the yeast will die and the fermentation power will be weakened, so it is wise not to freeze fresh yeast
[0007] Patent Document 1 describes granular frozen yeast, but it is only a product 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 of low fermentation power

Embodiment 1

[0055] The pressed fresh yeast made by KANEKA with dry matter weight 32% was packed in the mold of the shape and size shown in Table 1, and compression molding was performed using a hand press to obtain the shape, size, density, and weight shown in Table 1 ( weight per 1 shaped body) of fresh yeast shaped body. The dry matter weight of the yeast in this shaped body was 32.1%. In this example, CFB27-1 (accession number FERM BP-15903, described in Japanese Patent No. 4357007) was used as a yeast strain.

[0056] Next, 40 of the fresh yeast molded bodies were filled into polyethylene bags, and in the bagged state, they were frozen in an air-cooled freezer at -20°C for 2 months to obtain 40 frozen Packages for fresh shaped yeast. It should be noted that, during the bagging, the yeast molded bodies in the package were bagged so as to closely adhere to each other.

Embodiment 2~6

[0058] In the same manner as in Example 1, according to Table 1, packages of fresh yeast shaped bodies and frozen fresh yeast shaped bodies were obtained.

reference example 1

[0069] According to Example 11 of Japanese Patent Document 2, a package of tiny frozen fresh yeast mixed with edible fats and oils and an emulsifier was obtained. Specifically, as follows.

[0070] Mix 500 g of KANEKA block fresh pressed yeast with a dry matter weight of 32% according to the formula in Table 1, mix it with an emulsifier (sorbitan monostearate) and edible oil (hardened rapeseed oil), and then granulate it in a spherical shape Machine forming, obtain the spherical fresh yeast shaped body that diameter is 3.0mm. Next, the entire amount of the fresh yeast molded body was filled in a polyethylene bag, and in the bagged state, it was frozen in an air-cooled freezer at -20° C. for one week to obtain a package of frozen fresh yeast.

Abstract

The purpose of the present invention is to provide a frozen fresh yeast formed body: by which the leavening power of fresh yeast is maintained after long-term storage by freezing, even without addingculinary fat or an emulsifier; and in which one piece of the frozen formed body does not strongly adhere to another piece of the frozen formed body, and even if the frozen formed bodies adhere to oneanother, the frozen formed bodies can easily be separated, making it possible to measure the yeast amount by counting the number of the frozen formed bodies. Provided is a frozen fresh yeast formed body comprising frozen fresh yeast, in which the shape of a piece of the formed body approximates a ball with the maximum width of 2-20 cm. With respect to the total weight of the frozen fresh yeast formed body, the yeast content is 25-40 wt% in terms of dry weight, and the water content is 60-75 wt%. It is preferable that the maximum area of contact between two pieces of the frozen fresh yeast formed body is 20% or less of the total surface area of one piece of the formed body.

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, the number of unskilled operators has increased due to the flow and internationalization of human resources in the bread manufacturing industry. In addition, due to intensified cost competition, it is desired to simplify and improve the efficiency of the bread manufacturing process. [0003] The distribution forms of yeast for bread making are roughly divided into fresh yeast, dry yeast, and semi-dry yeast. Fresh yeast, also known as pressed yeast, is sold in block or powder form. Compared with dry yeast or semi-dry yeast, this type of fresh yeast has a stronger ability to decompose granulated sugar, supports the characteristics of good flavor and high fermentation power, and is the most widely distributed in the market. [0004] However, fresh yeast has weak tolerance to dryness...
