가공식품의 보존성 향상방법{Method for Improving Preservation of Processed Foods}Method for Improving Preservation of Processed Foods

도 1은 젖산나트륨을 함유한 가공품의 풍미에 대한 pH와 아세트산나트륨의 영향을 나타내는 도면.BRIEF DESCRIPTION OF THE DRAWINGS The figure which shows the effect of pH and sodium acetate on the flavor of the processed goods containing sodium lactate.

본 발명은 식육제품, 어육반죽제품, 각종 식육반찬 등의 가공식품의 본래의 풍미에 실질적인 영향을 주지 않고, 부패와 변질에 관여하는 미생물의 증식을 억제하여 보존성을 향상시키는 가공식품의 보존성 향상방법에 관한 것이다.The present invention does not substantially affect the original flavor of processed foods such as meat products, meat dough products, various meat side dishes, and improves the preservation of processed foods to suppress the proliferation of microorganisms involved in corruption and deterioration to improve the preservation It is about.

근래, 소비자요구의 변화와 함께 가공식품도 다양화되고, 소비자의 건강지향을 반영한 저지방, 저염화 제품도 증가하고 있다. 특히 식염 등의 저감으로 미생물학적인 보존성이 저하되기도 한다. 이런 상황에서 유통, 판매, 소비단계를 통하여 가공식품의 미생물학적인 안전성을 확보하면서, 보존성을 향상시키며 가공식품의 풍미 등에도 악영향을 주지 않는 보존성 향상방법이 요구되고 있었다. 이러한 보존성 향상방법에 관해서는 이하와 같은 기술이 공개되어 있다.Recently, processed foods are diversifying, along with changes in consumer demand, and low-fat, low-flammation products reflecting consumer health orientations are increasing. In particular, microbiological preservation may be reduced due to the reduction of salt. In this situation, there is a demand for a method of improving the preservation of the processed foods while ensuring the microbiological safety of the processed foods through distribution, sales, and consumption stages, and not affecting the flavor of the processed foods. The following technique is disclosed about the improvement method of such storage.

일본국 특개소59-175870호 공보에는 글리신이 갖는 살균작용을 상승적으로 높이고, 게다가 식품에 대하여 식미, 식감 등의 기호면에 하등의 악영향을 미치지 않는 가공식품의 보존성 향상방법으로서, 글리신 0.1∼1.0중량% 및 글리신의 50∼500중량%에 상당하는 아세트산염 및/또는 젖산염을 함유시킨 가공식품의 보존성 향상방법이 기재되어 있지만, 특히 많은 식품에서 산패 등의 변질원인균이 되는 젖산균에 대하여 충분한 효과를 얻기 위해 각각의 성분의 첨가량을 증가시켰지만, 글리신에 의한 단맛, 아세트산나트륨에 의한 신맛, 젖산나트륨에 의한 금속적인 맛이 나타나서 풍미밸런스상 문제가 없다고는 말할 수 없었다.Japanese Patent Application Laid-Open No. 59-175870 discloses a method for improving the preservation of processed foods which synergistically increases the bactericidal action of glycine and does not adversely affect food taste, texture and the like. Although a method for improving the shelf life of processed foods containing acetate and / or lactic acid salt equivalent to 50% to 500% by weight of glycine has been described, in particular, in many foods, it has a sufficient effect against lactic acid bacteria, which is a cause of deterioration such as rancidity. Although the amount of each component was increased to obtain, sweetness by glycine, sour taste by sodium acetate, and metallic taste by sodium lactate appeared, and there was no problem in flavor balance.

일본국 특개소62-201563호 공보에는 프로타민에 특정의 항균성물질을 조합함으로써 단독으로는 얻어지지 않는 상승효과를 발휘시키고, 식품의 보존에 실효성이 있는 자연물을 중심으로 하는 식품보존료로서 글리신, 아세트산나트륨, 리소자임, 감초추출항균성물질, 저급지방산에스테르, 슈가에스테르, 비타민B1에스테르, 중합인산염으로 된 특정 항균성물질군으로부터 선택된 1종 또는 2종 이상과 프로타민을 조합시킨 식품보존료가 기재되어 있지만, 구성성분인 프로타민은 본 발명의 바람직한 대상인 식육반찬류의 주성분인 단백질에 대해 유효한 정균효과를 가지고 있지 않아 만족할 수 있는 식품보존효과는 기대할 수 없었다.Japanese Patent Application Laid-Open No. 62-201563 discloses a synergistic effect not obtained by combining a specific antimicrobial substance with protamine, and glycine and sodium acetate as food preservatives centered on natural substances effective for the preservation of food. , Food preservatives in which one or two or more selected from a specific antimicrobial substance group consisting of lysozyme, licorice extract antibacterial substance, lower fatty acid ester, sugar ester, vitamin B1 ester, and polymerized phosphate are described. Protamine does not have an effective bacteriostatic effect on the protein, which is the main component of the meat side dishes, which is a preferred subject of the present invention, and thus a satisfactory food preservation effect cannot be expected.

일본국 특개평5-72호의 공보에는 식품의 보존성을 향상시키는 효과가 크고, 식품의 풍미에 영향을 주지 않는 식품의 보존성향상제로서, 아디핀산, 구연산, 주석산, 푸말산 및 사과산으로부터 선택된 적어도 1종의 유기산 및/또는 그 염, 0.1∼30%, 리소자임 0.01∼10%, 에탄올 0.1∼90%, 및 포화지방산의 탄소수가 8∼12의 글리세린 지방산에스테르 0.05∼50%를 유효성분으로 하는 식품보존성 향상제가 기 재되어 있지만, 탄소수가 8∼12의 글리세린 지방산에스테르를 구성성분으로 하고 있기 때문에 쓴맛을 가지며, 식품의 풍미에 악영향을 주었다. 또한 미생물학적인 발육저지효과가 약해 고농도로 첨가해야 하는 결점도 있었다.Japanese Unexamined Patent Publication No. 5-72 discloses at least one selected from adipic acid, citric acid, tartaric acid, fumaric acid and malic acid as preservatives for improving food preservation and having no effect on food flavor. Food preservation as an active ingredient of 0.05 to 50% of an organic acid and / or a salt thereof, 0.1 to 30%, lysozyme 0.01 to 10%, ethanol 0.1 to 90%, and saturated fatty acid having 8 to 12 glycerine fatty acid esters Although I have been described, it has a bitter taste and adversely affects the flavor of food because it contains a glycerin fatty acid ester of 8 to 12 carbon atoms. In addition, there is a defect that the addition of high concentration due to the weak microbiological inhibition effect.

일본국 특개평8-196252호 공보에는 식육제품 등의 보존성식품에서 뛰어난 정균효과에 의해 보존성을 향상시키고, 미질이 순하고 용해성이 뛰어난 균형이 잡힌 식품보존성 향상제로서, 리소자임, 아미노산 또는 그 염, 유기산 또는 그 염 및 아세트산염을 함유하는 것을 특징으로 하는 식품보존성 향상제가 기재되어 있으며, 구체적으로는 아미노산이란 예를 들어 아디핀산, 푸말산, 사과산, 주석산, 젖산 또는 구연산 등으로부터 선택된 1종 이상이며, 아세트산염이란 예를 들어 아세트산나트륨 등인 것으로 개시되어 있다. 그러나, 특히 많은 식품에서 산패 등의 변질원인균이 되는 젖산균에 대해 충분한 효과를 얻기 위해 각각의 성분의 첨가량을 증가시켰지만, 글리신에 의한 단맛, 아세트산나트륨에 의한 신맛, 젖산나트륨에 의한 금속적인 맛이 나타나 풍미밸런스상 문제가 없다고는 말할 수 없었다.Japanese Unexamined Patent Application Publication No. 8-196252 discloses a balanced food preservation enhancer which improves preservation by excellent bacteriostatic effect in preservative foods such as meat products, and is mild in taste and solubility, and includes lysozyme, amino acid or salt thereof, organic acid or A food preservation enhancer is described which contains the salt and the acetate salt. Specifically, the amino acid is at least one selected from, for example, adipic acid, fumaric acid, malic acid, tartaric acid, lactic acid, citric acid, and the like, and acetic acid. A salt is disclosed to be sodium acetate etc., for example. However, especially in many foods, the amount of each component was increased to obtain sufficient effects on lactic acid bacteria, which are the causes of deterioration such as rancidity. However, sweetness by glycine, sour taste by sodium acetate, and metallic taste by sodium lactate appeared. I could not say that there was no problem in flavor balance.

일본국 특개평9-23860호 공보에는 아세트 또는 아세트산을 사용하여 식품의 보존성을 높이면서 아세트 또는 아세트산의 풍미, 산미가 혀로 느껴지지 않는 식품보존료로서, 아세트 또는 아세트산과, 아디핀산, 푸말산, 글루콘산, 글루콘델타락톤, 구연산염, 주석산염, 젖산염 및 사과산염으로 구성된 군으로부터 선택된 1종 또는 2종 이상의 유기산 및/또는 유기산염을 혼합하여 된 식품보존료가 기재되어 있지만, 아세트 또는 아세트산을 사용한 경우의 산미저감에 관한 발명이며, 상세한 설명에도 있듯이, pH 4.8 이하의 가공품에만 충분한 효과를 기대할 수 있는 등의 문제가 있었다.Japanese Unexamined Patent Application Publication No. 9-23860 discloses a food preservative which does not feel the flavor or acidity of acet or acetic acid while improving the preservation of food using acet or acetic acid.

종래의 가공식품의 보존성 향상방법은 풍미를 중요시하면서도 뭐니뭐니해도 보존성에 중점을 둔 것이었지만, 본 발명자들은 시점을 바꾸어 가공식품 본래의 풍미에 실질적인 영향을 미치지 않는 범위에서 보존성을 추구한다는 연구에 몰두하였다. 본 발명의 과제는 가공육류, 식품반찬 등의 가공식품 본래의 풍미에 실질적인 영향을 미치지 않고, 부패와 변질에 관여하는 미생물의 증식을 억제하여 보존성을 향상시킬 수 있는 가공식품의 보존성 향상방법을 제공하는데 있다.The conventional method for improving the preservation of processed foods was to focus on the preservation even if the importance of flavor is important, but the present inventors have been devoted to the study that changes the viewpoint to pursue the preservation in a range that does not substantially affect the original flavor of the processed food. It was. SUMMARY OF THE INVENTION An object of the present invention is to provide a method for improving the preservation of processed foods that can improve the preservation by suppressing the growth of microorganisms involved in decay and deterioration without substantially affecting the original flavor of processed meats and side dishes. It is.

본 발명자들은 상기 과제를 해결하기 위하여 여러 가지 검토, 조사하였다. 미생물의 증식억제작용에 의해 식품의 보존성향상에 효과가 있는 유기산과 유기산염을 식품에 사용한 경우, 정균효과와 풍미에 미치는 영향이 각각 다르기 때문에 종래부터 다양한 연구가 있었다. 그러나 지금까지 가공식품 본래의 풍미에 실질적으로 영향을 미치지 않는 범위에서 보존성을 추구하고자 하는 시도는 발견할 수 없었다. 일반적으로 정균효과가 pH에 좌우(pH가 산성측으로 기울어질수록 효과적이다.)되는 것인데 비해, 젖산의 경우는 pH에 의한 영향을 받기 어렵고, 가공식품의 주된 변질원인균이 되는 젖산균 등 그람양성균에 대해 넓은 pH영역에서 효과적이라는 것이 인비트로(in vitro)의 실험계에서 명백하게 되어 있지만(마쓰다 등: 일식공시, 제41권, 제10호, pp687-702 (1994년)), 지금까지 이런 젖산의 기능을 가공식품계에서 실증하여 보존성 향상책으로 응용한 예는 없었기 때문에 젖산의 이용을 생각하였다.MEANS TO SOLVE THE PROBLEM The present inventors examined and investigated in order to solve the said subject. When organic acids and organic acid salts, which are effective in improving the preservation of foods by the effect of inhibiting the growth of microorganisms, are used in foods, various studies have been made since the effects on bacteriostatic effects and flavors are different. However, so far no attempt has been made to seek preservation in a range that does not substantially affect the original flavor of processed foods. In general, the bacteriostatic effect depends on pH (the more effective the pH is inclined toward the acidic side), the less lactic acid is affected by pH, and against gram-positive bacteria such as lactic acid bacteria, which are the main altering agents of processed food. Although effective in a wide range of pH has been evident in the laboratory system in vitro (Mazda et al .: Japanese Laid-Open Publication, Vol. 41, No. 10, pp 687-702 (1994)). Lactic acid was considered to have been used in the processed food industry because there have been no examples that have been applied to improve the preservation.

After the raw materials were weighed according to the basic formulation, sodium lactate was weighed and added to the amount shown in Table 1 with respect to the total amount of the material, and mixed sufficiently. About 100 g of the mixed material was shaped and heated, and both sides were heated with the heating plate until it became 80 degreeC of center temperature. After heating, it was cooled for about 10 minutes and used for the following test.                     

(3) 소세지(3) sausage

소세지의 기본배합은, 저민 돼지고기(로스부위 5mm로 그라인드한 것), 65중량%, 식염 1.5중량%, 중합인산염 0.2중량%, 전분 4.5중량%, 얼음 28.8중량%로 하였다. 기본배합에 따라서 원재료를 개량한 후, 젖산나트륨을 재료전량에 대하여 표 1에 나타낸 첨가량이 되도록 계량하였다. 그 후, ①저민 고기, 얼음, ②식염, 중합인산염, 젖산나트륨, ③전분의 순으로 첨가하면서 음식물컷터로 혼합하였다. 이를 염화비닐리덴케이싱에 약 150g 충전한 후, 양단을 묶었다. 이어서, 70℃의 수조에서 제품중심이 70℃에 도달하고 나서 20분간 가열하였다. 가열후, 얼음물로 약 30분간 냉각한 후, 0∼2℃의 냉장고에 하룻밤 보관하여 이하의 시험에 이용하였다.The basic formulation of the sausage was made from minced pork (grinded to 5 mm loin), 65% by weight, salt 1.5% by weight, polyphosphate 0.2% by weight, starch 4.5% by weight and ice 28.8% by weight. After the raw materials were improved according to the basic formulation, sodium lactate was weighed so as to add the amounts shown in Table 1 to the total amount of the materials. Thereafter, the mixture was mixed with a food cutter while adding (1) minced meat, ice, (2) salt, polymerized phosphate, sodium lactate, and (3) starch. After charging about 150 g of vinylidene chloride casing, both ends were tied up. Subsequently, after the product center reached 70 degreeC in the 70 degreeC water bath, it heated for 20 minutes. After heating, after cooling with ice water for about 30 minutes, it was stored overnight in a refrigerator at 0 to 2 ° C and used for the following tests.

(4) 조미돈육(4) seasoned pork

불고기용 조미돈육의 기본배합은 돼지고기로스부위(약 2mm 두께로 슬라이스한 것) 70중량%, 불고기용 조미국물 30중량%로 하였다. 기본배합에 따라서 원재료를 계량한 후, 젖산나트륨을 전량에 대하여 표 1에 나타낸 첨가량이 되도록 계량 첨가하고 충분히 혼합하였다. 혼합한 후, 하룻밤 0∼2℃의 냉장고에서 보관하였다. 그 후, 가열판으로 양면을 서로 굽고 충분히 가열된 것을 육안으로 확인한 후, 이하의 시험에 이용하였다.The basic formulation of seasoned pork for bulgogi was 70% by weight of pork loin (sliced to a thickness of about 2 mm) and 30% by weight of seasoned pork for bulgogi. After the raw materials were weighed according to the basic formulation, sodium lactate was metered in to the addition amount shown in Table 1 with respect to the total amount, and the mixture was sufficiently mixed. After mixing, it was stored in a refrigerator at 0 to 2 ° C. overnight. Thereafter, both sides were bent with a heating plate and visually confirmed to be sufficiently heated, and then used for the following tests.

각각의 제조방법에 따라서 조제된 공시품에 대하여 5명의 훈련된 패널로 관능평가를 하였다. 관능평가는 먼저 품목마다 각각의 패널이 개별적으로 평가하였다. 얻어진 결과에 대하여 다시 5명의 패널 상호간에 토의를 하고, 각 평가샘플을 [○: 양호; △: 조금 짠맛, 금속적인 맛이 있음; ×: 현저히 짠맛, 금속적인 맛이 있음]이라는 기준에 의해 평가하였다. 그 결과를 표 1에 나타낸다.Sensory evaluation was carried out by five trained panels on specimens prepared according to each manufacturing method. Sensory evaluation was first evaluated by each panel individually for each item. The results obtained are further discussed with each other by the five panelists, and each evaluation sample is [o: good; △: slightly salty, metallic taste; X: remarkably salty and metallic taste]. The results are shown in Table 1.

젖산나트륨(%)Sodium lactate (%) 0.00.0 0.50.5 1.01.0 1.51.5 2.02.0 2.52.5 3.03.0 3.53.5 품목subject 닭경단Chicken dumplings OO OO OO OO OO ×× ×× 햄버거hamburger OO OO OO OO OO OO ×× 소세지sausage OO OO OO OO OO OO ×× 조미돈육Seasoned Pork OO OO OO OO OO OO OO

표 1로부터도 알 수 있듯이, 젖산나트륨의 첨가에 의해 짠맛과 금속적인 맛을 느끼는 경향이 확인되었다. 또한 그 영향은 가공식품의 종류에 따라서 다르며, 비교적 담백한 맛인 닭경단에서는 2.5중량%에서, 또한 햄버거, 소세지에서는 3.0중량%, 조미돈육에서는 3.5중량%로 확인되었다. 그 결과로부터 가공품중에서 닭경단이 가장 풍미에 대한 영향이 나오기 쉽고 그 때의 첨가량의 한계가 거의 2중량%인 것이 명백해졌다.As can be seen from Table 1, the tendency to feel salty and metallic taste was confirmed by the addition of sodium lactate. In addition, the effect is different depending on the type of processed food, the relatively light taste of chicken dumplings in 2.5% by weight, hamburgers, sausages 3.0% by weight, seasoned pork was confirmed by 3.5% by weight.

이어서, 젖산나트륨과 병용하는 유기산염을 다수 스크리닝하고, 아세트산나트륨에 주목하였다. 여기서의 시험은 다른 pH의 가공식품에 대한 젖산염과 아세트산염의 조합에 의한 풍미에 대한 영향에 대하여 조사 검토하고, 적정한 이용방법을 찾아내기 위해 행하였다. 젖산염에 의한 풍미에 대한 영향을 받기 쉬었던 닭경단을 공시품으로 하였다. 닭경단의 기본배합은 저민 닭고기(다리고기를 5mm로 그라인드한 것) 67중량%, 생빵가루 13중량%, 계란 8중량%, 물 11.14중량%, 식염 0.8중량%, 후추 0.06중량%로 하였다. 또한 소정의 pH로 하기 위하여 우지로 코팅된 푸말산과 2N-NaOH를 이용하였다. pH의 조정은 미리 예비시험에서 가열후 소정의 pH가 되는 첨가량을 구하고 배합량을 설정하였다. 기본배합에 따라 원재료 및 pH조정제를 계량한 후, 젖산나트륨과 아세트산나트륨을 재료전량에 대하여 표 2에 나타낸 첨가량이 되도록 계량 첨가하고 충분히 혼합하였다. 혼합한 재료를 약 30g씩 경단형상으로 정형하고, 약 95℃의 열수 중에서 중심온도 80℃가 될 때까지 가열하였다. 가열후, 약 10분 냉각하고, 관능평가에 이용하였다.Subsequently, many organic acid salts combined with sodium lactate were screened and attention was paid to sodium acetate. The test here was carried out to investigate the effect on flavor by the combination of lactate and acetate salts on processed foods of different pH, and to find an appropriate method of use. Chicken dumplings, which were susceptible to the flavor caused by lactate, were used as specimens. The basic composition of chicken dumplings was 67% by weight of minced chicken (grinded to 5mm), 13% by weight of bread, 8% by weight of egg, 11.14% by weight of water, 0.8% by weight of salt, and 0.06% by weight of pepper. In addition, fumaric acid coated with Uji and 2N-NaOH were used to obtain a predetermined pH. The pH was adjusted in advance in a preliminary test to determine the addition amount to be a predetermined pH and set the blending amount. After the raw materials and the pH adjuster were weighed according to the basic formulation, sodium lactate and sodium acetate were metered in to the addition amount shown in Table 2 with respect to the total amount of the material, and mixed sufficiently. About 30 g of the mixed material was shape | molded in the shape of a dumpling, and it heated in the hot water of about 95 degreeC until it became 80 degreeC of center temperature. After heating, it was cooled for about 10 minutes and used for sensory evaluation.

조제된 공시샘플에 대하여 5명의 훈련된 패널로 관능평가를 하였다. 관능평가는 먼저 각 샘플마다 각각의 패널이 개별적으로 평가하였다. 얻어진 결과에 대하여 다시 5명의 패널 상호 토의를 하고, 각 평가샘플을 [○: 양호; △: 조금 신맛, 짠맛, 금속적인 맛이 있음; ×: 현저한 신맛, 짠맛, 금속적인 맛이 있음]라는 기준에 의해 평가하였다. 그 결과를 표 2에 나타낸다.Sensory evaluation was performed on 5 trained panels on the prepared samples. Sensory evaluation was first evaluated individually by each panel for each sample. Five panel discussions were conducted again on the obtained results, and each evaluation sample was [o: good; △: slightly acidic, salty, metallic taste; X: significant acidity, saltiness, metallic taste]. The results are shown in Table 2.

풍미에 대한 영향에 대해서는, 표 2로부터도 알 수 있듯이, 젖산나트륨은 어느 pH영역에서도 2중량%까지의 악영향은 확인되지 않았다. 한편, 아세트산나트륨의 경우, 젖산나트륨 2중량% 함유하는 경우에, 젖산나트륨의 함유량에 의존하지 않고, pH 5.5에서 0.4중량%, pH 6.0에서 0.5중량%, pH 6.5에서 0.6중량%까지 풍미에 대한 악영향은 확인되지 않았다. 이러한 젖산나트륨의 함유량에 의존하지 않는 경우의 풍미에 대한 pH와 아세트산나트륨의 영향을 표 2에 나타낸다. 이 경우의 아세트산나트륨(중량%)은 다음의 식(II)에서의 pH값의 일차함수로 나타낼 수 있음을 발견하였다. 이들의 결과로부터 젖산나트륨을 2중량% 정도 함유한 가공식품에 대하여 가 공식품의 pH에 따라 일정 비율로 아세트산나트륨의 첨가량을 변화시킴으로써 풍미에 대한 영향을 실질적으로 주지 않고 젖산나트륨과 아세트산나트륨을 병용할 수 있다는 것을 알았다.As can be seen from Table 2, the effect on the flavor was not found to adversely affect sodium lactate up to 2% by weight in any pH range. On the other hand, in the case of sodium acetate, when containing 2% by weight of sodium lactate, it does not depend on the content of sodium lactate, but 0.4% by weight at pH 5.5, 0.5% by weight at pH 6.0, up to 0.6% by weight at pH 6.5 No adverse effects were identified. Table 2 shows the effect of pH and sodium acetate on flavor when not depending on the content of such sodium lactate. It was found that sodium acetate (% by weight) in this case can be represented by the first function of the pH value in the following formula (II). From these results, sodium lactate and sodium acetate can be used in combination with processed foods containing about 2% by weight of sodium lactate by changing the amount of sodium acetate added at a constant rate according to the pH of the formula. I knew I could.

(시험결과)(Test result)

젖산나트륨, 아세트산나트륨 모두 첨가량의 증가에 따라 젖산균에 대한 정균효과는 증가하였다. 젖산나트륨은 pH가 5.5∼6.5의 사이에서 변화해도 거의 그 효과는 변화하지 않았지만, 아세트산나트륨은 pH가 높아지면 현저히 정균효과가 저하하는 것이 확인되었다. 또한 젖산나트륨과 아세트산나트륨을 조합시킴으로써 넓은 pH영역에서 상호부가적, 상승효과에 의한 정균효과의 상승이 확인되며, 또한 pH가 낮을수록 그 경향은 강하게 나타났다. 또한, 표 3의 결과와 상기 표 2의 결과(표 3의 진한 부분 참조)를 같이 생각하면, 젖산나트륨 2중량% 이하를 함유한 가공식품 에 대하여 가공식품의 pH에 따라 일정한 비율로 아세트산나트륨의 첨가량을 변화시킴으로써 풍미에 대한 영향을 주지 않고, 미생물학적인 보존성을 향상시킬 수 있는 것이 명백해졌다.As the amount of sodium lactate and sodium acetate increased, the bacteriostatic effect on lactic acid bacteria increased. Although sodium lactate hardly changed the effect even if pH changed between 5.5-6.5, it was confirmed that bacteriostatic effect remarkably decreased when sodium acetate became high pH. In addition, the combination of sodium lactate and sodium acetate increased the bacteriostatic effect due to mutual additive and synergistic effects in a wide pH range, and the lower the pH, the stronger the trend. In addition, considering the results in Table 3 and the results in Table 2 (refer to the darker part in Table 3), the ratio of sodium acetate at a constant ratio of processed foods containing 2% by weight or less of sodium lactate was determined according to the pH of the processed foods. By changing the addition amount, it became clear that the microbiological preservation can be improved without affecting the flavor.
