The present invention relates to a novel feed or food preservative. Propionic acid is an organic acid with antibacterial properties.
Useful for preventing mold in feed and food. However, this acid is liquid and volatile, and has an extremely strong odor and is inconvenient to handle, so its salts, sodium propionate and calcium propionate, are actually used. By the way, propionic acid is an acid-type antibacterial agent like sorbic acid, so its antibacterial properties depend on the pH of the feed or food to which it is added.
The lower the pH, the stronger the effect. Sodium propionate and calcium propionate are neutral or slightly alkaline and have no ability to lower pH. Furthermore, since it is the propionic acid molecule itself that has antibacterial activity, it is natural that propionic acid exhibits the strongest antibacterial activity compared to its sodium salt or calcium salt when added in the same amount.
Therefore, it would be of great industrial significance if the above-mentioned drawbacks of propionic acid could be overcome and propionic acid could be pulverized as it is and made into a stable form. Furthermore, since sodium propionate has strong hygroscopicity and calcium propionate has weak antibacterial properties, improvements in this respect are also desirable. The present inventors have arrived at the present invention as a result of intensive research to achieve such an objective. The present invention provides a feed or food preservative containing as an active ingredient a complex containing 0.1 to 10 mol of sodium propionate and 0.1 to 5 mol of calcium propionate per 1 mol of propionic acid, and containing propionic acid in a stable form. It is. The ratio of the three components in the composite used in the present invention is preferably 0.25 to 6.25 mol of sodium propionate and 0.5 to 2.5 mol of calcium propionate per mol of propionic acid. To prepare the above composite, first sodium propionate and calcium propionate are added to propionic acid and mixed. In this case, the amount of the three components used is preferably such that propionic acid is in excess of the above composition ratio. This mixture is then heated to dissolve it. The heating temperature is preferably 50 to 140°C, and the heating time is several minutes to several hours. The solution is then allowed to cool and solidify, and excess propionic acid is removed to obtain the above-mentioned composite. As a method for removing propionic acid, conventional drying methods such as ventilation drying, reduced pressure drying, spray drying, drum drying, etc. are used. The above-mentioned composite can also be prepared by adding inorganic calcium and inorganic sodium compounds to propionic acid and allowing it to act, and then removing the produced water and excess propionic acid. Examples of inorganic calcium compounds include calcium hydroxide, calcium carbonate, and calcium oxide, and examples of inorganic sodium compounds include sodium hydroxide, sodium carbonate, and sodium hydrogen carbonate. The reaction can also be carried out in the presence of an organic solvent. It is believed that the product has a certain composition and is not just a mixture. The preservative of the present invention may be used as the above-mentioned composite as it is, or may be formulated into a powder, granules, etc. by adding additives and added to feed or food. Examples of feed include livestock feed for cows, pigs, horses, and chickens, feed for poultry, feed for pets such as dogs and cats, feed for experimental animals such as rabbits and rats, and feed for farmed fish. The above-mentioned compound is added to feed or food at a concentration of 0.01 to 1
It is preferably used in a proportion of 0.05 to 0.7% by weight, particularly 0.05 to 0.7% by weight. The above composite is not simply a mixture of three components because it has almost no propionic acid odor, the amount of propionic acid hardly decreases during normal drying, it has almost no hygroscopicity despite containing sodium propionate, and This is clear from the X-ray diffraction image. Although it is possible to form some composites by simply mixing the three components, the composition is unspecified and the properties for use are unsatisfactory. Although the above-mentioned composite contains a considerable amount of propionic acid, it has almost no pungent odor characteristic of propionic acid, and does not have the strong hygroscopicity of sodium propionate. Moreover, compared to sodium propionate and calcium propionate, it has an extremely superior anti-mold effect on feed and food, for example. The existence of a double salt of propionic acid and sodium propionate is known, but this salt easily releases propionic acid and disappears when heated. In addition, a compound of propionic acid and calcium propionate can contain propionic acid in a stable form and has almost no pungent odor or hygroscopicity, but it has a mildewproofing effect on feed compared to sodium propionate and calcium propionate. low. For these reasons, the above-mentioned composite is recognized as a novel composition, and exhibits excellent effects that cannot be obtained by using each component alone, a composite of two components, or a mere mixture of three components. Example 1 0.11 to 0.24 mol of sodium propionate and 0.095 to 0.22 mol of calcium propionate are added to 1 mol of propionic acid, and the mixture is heated to 140°C with stirring to dissolve. After dissolving, the solution is allowed to cool and solidify,
The resulting transparent coagulum was crushed to form a slurry, and excess propionic acid was dissolved at 20 torr and 50-60 torr.
Removed at °C. The slightly damp lump was spread on a enamel plate and dried with ventilation at 50 to 60°C for about 6 hours, with occasional crushing, to obtain a white, free-flowing powder. This powder has almost no propionic acid odor. Furthermore, the X-ray diffraction image did not have any diffraction peaks seen in the mixture of sodium propionate and calcium propionate, and diffraction peaks not seen in this mixture were observed. Table 1 shows the component composition, odor and moisture absorption state of the composite of the present invention and comparative sodium propionate alone, a mixture of sodium propionate and calcium propionate, and a double salt of the two components. Furthermore, propionic acid 1
The mixing ratio (mol) of the other two components to the mole is as follows.

Next, 80 g of 50% sodium hydroxide (1 mol of NaOH) was gradually added dropwise, and after the addition was completed, the mixture was heated at 100 to 120°C.
The mixture was heated and stirred for 30 minutes. Next, let the contents cool and solidify, crush them finely and spread them in a glass tray.
After drying with ventilation at 50 to 60°C for 8 hours while occasionally crushing in a mortar, a white, free-flowing powder was obtained, with almost no propionic acid odor. This compound(6)
The water content was 0.9%, the molar ratio of propionic acid, sodium propionate and calcium propionate was 2.0:1.9:1.0, and it showed the same X-ray diffraction pattern as Composite 4 of Example 1. Example 3 A feed antifungal test was conducted using the composites prepared in Examples 1 and 2. The test method is as follows. Commercially available mixed feed for dairy cows (moisture content 13.4%)
Each test drug was added at 0.1% and 0.2% and mixed well to prepare test feed. Put 50g of this feed into a 100ml beaker, put it in a desiccator adjusted to 30°C and a relative humidity of 92.6% (using a saturated aqueous solution containing potassium nitrate crystals), and store it in a constant temperature room at 30°C. The samples were observed over time to determine the number of effective storage days until mold appeared. The test was repeated twice,
The average number of effective storage days was determined. The pH of the feed was measured by suspending it in 10 times the volume of deionized water before the start of the storage test, and it was 6.86, and the effective storage period was 12 days. The test results are shown in Table 2.

果を第３表に示す。[Table] It is clear that all of the above-mentioned composites have better preservative effects than sodium propionate or calcium propionate. Example 4 400g of wheat flour (strong flour), 248ml of water, 16g of sugar,
8g yeast, 16g toning, 7.2g salt
Dough was prepared by kneading 0.9 g of fermentation accelerator with or without addition of 0.2% of calcium propionate or the composite of the present invention, and bread was made by the shoot time method. After baking, six slices of bread were sliced from one test section, placed two slices each in a polyethylene bag, and placed in a thermostat at 30°C for a storage test. The results are shown in Table 3.
