The present invention relates to a method for producing Yokan. Specifically, the present invention relates to a method for producing a stable yokan (yokan) characterized by adding polyglycerin fatty acid ester to the yokan (yokan). [Industrial Application Field] The method for preserving yokan of the present invention is useful for preserving yokan for a long period of time in the diet, allowing it to be eaten easily and hygienically anytime and anywhere, and for producing it economically. [Prior Art] Along with changes in eating habits and tastes, there is a tendency for people to "give up on sweetness" in Yokan as well.
The sterilization process for yokan is a common commercial sterilization process and does not reach complete sterilization because the taste of the yokan changes due to heat treatment. Yokan that has been sterilized in this way will not deteriorate under normal storage conditions. However, under such sterilization conditions, heat-resistant bacterial spores remain. These heat-resistant bacterial spores rarely germinate or proliferate under normal storage conditions, so they are very unlikely to cause problems in yokan. However, if the yokan is stored at high temperatures or has a lower sugar content, the remaining heat-resistant bacterial spores will germinate and multiply, causing the yokan to deteriorate and deteriorate. In order to kill these heat-resistant bacterial spores, there is a method of raising the sterilization temperature, but this method has a negative effect on the physical and chemical properties of the food, reducing its value as a food. Therefore, the sterilization process cannot be heated above a certain temperature. There is also a method of lowering the pH below 5, but this changes the taste of the yokan and makes it taste bad. [Problems to be solved by the invention] For these reasons, it is possible to improve the killing rate of heat-resistant bacterial spores remaining in the yokan without raising the sterilization temperature of the yokan, or to improve the killing rate of heat-resistant bacterial spores remaining in the yokan without raising the sterilization temperature of the yokan, or even if sterilized yokan is stored for a long period of time. It has been desired to develop a method to suppress the germination and proliferation of heat-resistant bacterial spores. The present invention provides a method that can produce yokan with a low sugar content using a commercial sterilization method, suppresses the germination and proliferation of heat-resistant bacterial spores even when stored at high temperatures, and has good storage stability over a long period of time. It is something to do. [Means for Solving the Problem] The present inventors have worked diligently to develop a method for producing Yokan that suppresses the germination and proliferation of heat-resistant bacterial spores during high temperature or long-term storage of Yokan, and that has good storage stability. As a result of our research, we invented a preservation method that involves adding polyglycerol fatty acid ester to yokan. The polyglycerin fatty acid ester used in the present invention is a fatty acid ester such as diglycerin, triglycerin, tetraglycerin, hexaglycerin, octaglycerin, or decaglycerin. Fatty acids used in polyglycerin fatty acid ester include caprylic acid, capric acid,
It is a saturated or unsaturated straight chain fatty acid having 8 to 16 carbon atoms, such as lauric acid, myristic acid, and palmitic acid, and these fatty acids may be used alone or as a mixture thereof. If the chain length of the fatty acid is shorter than 8, the taste will be poor and this is not preferable. Furthermore, if the chain length of the fatty acid is longer than 18, the effect of the present invention against heat-resistant bacterial spores cannot be obtained. The polyglycerin fatty acid ester is a mono-, di-, tri-, or tetra-fatty acid ester of the polyglycerin, and among these, mono- and di-fatty acid esters are preferable, and these can be used alone or in a mixture thereof. The polyglycerin fatty acid ester used in the present invention is 0.02 to 1.0% (parts by weight) based on Yokan.
Added. If the amount added is less than 0.02%, the effect of the present invention will not be achieved, and if the amount added is more than 1.0%, the polyglycerin fatty acid ester will affect the flavor of the food and become economically expensive, which is not desirable. In addition to the polyglycerol fatty acid ester of the present invention, glycerin fatty acid ester, sucrose fatty acid ester, propylene glycol fatty acid ester, sorbitan fatty acid ester, lecithin, etc. can be added to the yokan. The yokan of the present invention includes white yokan, red bean yokan, matcha yokan, Shinonome yokan, plum yokan,
In addition to kneaded yokan such as yuzu yokan and chestnut yokan, there are also kindama yokan and steamed yokan. Among them, the yokan of the present invention has a low sugar content,
The effect is most expected in water-filled yokan. [Action] The polyglycerol fatty acid ester of the present invention is a surfactant with very strong hydrophilicity and a large HLB, so it acts on the cell membranes on the surface of bacteria, yeast, and mold to suppress the germination and proliferation of microorganisms. It is estimated to be. Next, the present invention will be explained with reference to examples. Example 1 24 g of thread agar was immersed in 3500 g of water in which 48 g of decaglycerin monomyristate was dissolved, and then heated and boiled to completely dissolve the thread agar.
After that, 900g of sugar was added and dissolved, 1200g of fresh bean paste and 12g of matcha dissolved in lukewarm water were added, and the mixture was brought to a boil again. Further, 5 g of common salt was added, boiled down, filtered through a hair sieve, cooled to 40 to 50°C, poured into a cup, and solidified to obtain water yokan. Water content of water yokan is approx.
It was 65%. Heat this water yokan to 120℃ for 30 minutes.
After heat sterilization for minutes, heat-resistant bacteria (55°C, 5 days) were measured on a standard agar medium. In addition, this water yokan was stored at 40°C for 7 days and its condition was observed. The results are shown in Table 1. Example 2 24 g of thread agar was immersed in 3500 g of water in which 32 g of decaglycerin monopalmitate was dissolved, and then heated and boiled to completely dissolve the thread agar.
After that, 900g of sugar was added and dissolved, 1200g of fresh bean paste and 12g of matcha dissolved in lukewarm water were added, and the mixture was brought to a boil again. Further, 5 g of common salt was added, boiled down, filtered through a hair sieve, cooled to 40-50°C, poured into a cup, and solidified to obtain mizuyokan. Water content of water yokan is approximately 64
