Description

[Technical Field]

[0001] The present invention relates to an agent for inhibiting the generation of putrid odor from food-derived garbage, and a food waste odor deodorizing composition and food waste odor deodorizing product containing the same. [Background technology]

[0002] In recent years, awareness of deodorization in daily life has been increasing, and various deodorizers suitable for various malodors, such as toilet odors, food waste odors, indoor odors, pet odors, and pet feces and urine odors, have been developed. In particular, the putrid odor of food-derived food waste may, in some cases, cause discomfort to people spending time in the kitchen or an adjacent living room. Therefore, there is a demand for the development of a deodorizer suitable for eliminating the putrid odor of food-derived food waste.

[0003] Various deodorizers suitable for eliminating malodors have been proposed. For example, Patent Document 1 discloses a deodorizer composition containing an alkanolamine compound, a polycarboxylic acid compound, and water, which is effective in eliminating malodors originating from food waste and denatured oil stains.

[0004] Furthermore, for example, Patent Document 2 discloses a deodorizer composition having excellent deodorizing performance against malodor emanating from human or pet excrement or food waste, which comprises at least one selected from tetravalent metal phosphates and aluminum silicates, and at least one selected from the group consisting of hydrated zirconium oxide, zirconium oxide, zinc oxide, basic zinc carbonate, hydrotalcite compounds or their calcined products, and inorganic compounds carrying at least one metal ion selected from copper ions, zinc ions, and manganese ions.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-23090 [Patent Document 2] Japanese Patent Application Laid-Open No. 2003-38623 Summary of the Invention [Problem to be solved by the invention]

[0006] The deodorizer compositions described in Patent Documents 1 and 2 are intended to eliminate odors that have already been generated. However, food waste usually needs to be stored in each household for a certain period of time before being collected by a garbage truck, and during that time, a putrid odor of the food waste (especially food) occurs, which has the problem of gradually becoming stronger. Therefore, simply deodorizing the food waste odor that has already been generated is not necessarily a sufficient means of dealing with the putrid odor of food-derived food waste. [Means for solving the problem]

[0007] The present inventors have focused on suppressing the generation of putrid odors from food-derived garbage in advance, rather than on deodorizing the odors of food waste that have already been generated, and as a result of various investigations, have found that a certain component or combination of components effectively acts as an inhibitor for the generation of putrid odors from food-derived garbage. Furthermore, they have found that compositions and products containing the inhibitor for the generation of putrid odors from food-derived garbage also exhibit excellent deodorizing and antifungal effects against food waste odors, and can also prevent the attraction of small gnats or flies, leading to the completion of the present invention.

The impregnated body was then suspended in the flask so as not to come into contact with the food, and the flask was then sealed with a rubber stopper. After storage at room temperature (25°C) for 7 days, the odor concentrations of ammonia, trimethylamine, and methyl mercaptan in the flask were measured using a gas detector tube (manufactured by Gastec Corporation). In addition, an untreated group was stored under the same conditions as the treated group, except that the chemical-impregnated body was not hung, and the odor concentrations of ammonia, methyl mercaptan, and trimethylamine in the flask after 7 days of storage at room temperature (25°C) were also measured using a gas detection tube (manufactured by Gastec Corporation). The putrid odor generation inhibition rate (%) was calculated based on the measurement results using the above formula (I). (The test results are shown in Table 3.)

[0039] [Test Example 3] Test 3 for suppressing putrid odor generation from food-derived garbage Foods that may be of concern include: bread, potatoes, madeleines, apples, dried sardines, yellowtail, raisins, rice, konjac, eggplant, shiitake mushrooms, carrots, crab, yuzu, shimeji mushrooms, yogurt, rape blossoms with sesame dressing, rice, broccoli, ginger, peas, kamaboko, condensed milk, bananas, mandarin oranges, sausages, smoked squid, garlic, lactic acid bacteria drinks, bean sprouts, shrimp, tartar sauce, tuna rolls, maple syrup, soba noodles, seasoned vinegar, crab miso, Chinese soup stock, sugar, honey, soy pulp, lemon, fried chicken, natto, filleted horse mackerel, squid tentacles, pickled radishes, spinach, bitter melon, green onions, boiled eggs, pickled plums, mozuku seaweed, tomatoes, pears, raw chicken, beer, ramen, bean sprouts, lotus root, myoga ginger, enoki mushrooms, butter, mayonnaise, A test similar to Test Example 2 was conducted using appropriate amounts of soy sauce, bell peppers, cookies, soybeans, frozen gratin, raw beef, Chinese cabbage, shiso leaves, apple pie, dried small sardines, cabbage, miso, pork with ginger, Neapolitan spaghetti, peanuts, octopus, onion, seasoning for rice dishes, frozen fried rice, persimmon, celery, chives, wine, chikuwa, kiwi, mackerel, tofu, pumpkin, mochi, and raw fish, and a pulp chemical-impregnated body impregnated with the fragrance of Example 11, which is an agent for suppressing the generation of putrid odors from food-derived food waste of the present invention.The test was successful in suppressing the generation of putrid odors (ammonia, trimethylamine, and methyl mercaptan, or a combination of these) in all foods (by approximately 80 to 99%). Furthermore, when the appearance of each food was compared between the untreated and treated groups after storage for 7 to 14 days, mold had grown on the untreated food, whereas no mold had grown on the food (treated food) that had been treated with the agent of the present invention to inhibit the generation of putrid odors from food-derived garbage, confirming that the agent of the present invention also has excellent anti-mold effects.

[0040] [Test Example 4] Test 1 on the deodorizing effect of food waste odor A food waste odor deodorizing composition 1 containing 2 g of the fragrance of Example 11, 38 g of isopropanol, and 60 g of water was prepared, and 100 mL of this aqueous liquid was filled into a plastic trigger pump to obtain a food waste odor deodorizing product 1 containing the food waste odor deodorizing composition 1 of the present invention. 9g of raw shirasu and 5g of water were placed in a transparent PET cup (860cc), which was then covered and left to stand at room temperature (25°C) for 7 days. The odor concentrations of trimethylamine and ammonia in the cup were measured using a gas detector tube (manufactured by Gastec Corporation). Food waste odor eliminator product 1 was pushed three times through the gap in the lid, and the odor concentrations of trimethylamine and ammonia were measured using a gas detector tube (manufactured by Gastec Corporation) approximately one minute later. The deodorizing rate was calculated using the following formula (II), and it was found that a high deodorizing effect of 85% was obtained against both trimethylamine and ammonia.

[0042] [Test Example 5] Test 2 on the deodorizing effect of food waste odor Water was added to 5 g of the fragrance of Example 11, 2 g of a plant extract (trade name "Super Puriere", manufactured by Panasonic Eco Solutions Kaken Co., Ltd.), and 85 g of isopropanol to make a total volume of 250 mL, yielding food waste odor deodorizing composition 2. 250 mL of this aqueous liquid was filled into a plastic trigger pump, yielding food waste odor deodorizing product 2 containing food waste odor deodorizing composition 2 of the present invention. A 6.5L polystyrene trash can (product name "SCHON 65 NEO", manufactured by Richell Corporation) was filled with an empty natto container (no lid or plastic wrap), raw fish (saury head and innards), the container that the raw fish came in, and a raw onion. Ten pumps of food waste odor eliminator product 2 were then poured into the can, which was then sealed with plastic wrap. This was designated the treated area. The untreated area was also designated the untreated area, which was not treated with food waste odor eliminator product 2 but was sealed with plastic wrap. These were stored at room temperature (25°C) for 4 days.

[0043] 1. Testing with detector tubes The wrap was opened slightly for the treated and untreated areas, and a detector tube (manufactured by Gastec Corporation) was inserted to measure the concentration of food waste odor inside (Table 4).

[0044] [Table 4]

[0045] 2. Sensory test Eleven panelists smelled the interiors of the treated and untreated areas and rated the pleasantness or unpleasantness of the odor on a 9-point scale (+4: most pleasant, 0: neither pleasant nor unpleasant, -4: most unpleasant). The results for the treated and untreated areas were averaged (Table 5). [Table 5]

[0046] The test results showed that when food waste was treated with food waste odor elimination product 2, it showed excellent food waste odor elimination effects compared to when food waste was not treated, due to its ability to suppress the generation of putrid odors from food waste. [Industrial Applicability]
