Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a milky lotion-like antioxidant preparation effective in preventing the oxidation of foods and feeds, particularly marine products.

<Prior art> Protecting food and feed from oxidation by oxygen is very important in industry, and to date there have been many methods for protecting food and feed from oxidation by oxygen. →Some antioxidants are toxic and have been widely used.Therefore, highly safe natural antioxidants were developed, including tocopherol and flavone derivatives.

Antioxidant formulations have been developed that combine synergists with one or more of the natural antioxidants such as gallic acid derivatives, NDGA (nordihydroguaiaretic acid), bombol, sesamol, spices, amino acids, and the like.

<Problems to be solved by the invention> The above-mentioned natural antioxidants are safe and there are no problems, but using only one type of antioxidant does not provide sufficient antioxidant power, and there is a method to improve the antioxidant power by using multiple types. I've been exposed to it. Among them, a strong antioxidant effect can be obtained by combining tocopherol with Fetin Powder as a synergist. No acid inhibitors were found.

, 4- The emulsion is destroyed due to the low value of the 10th day, so why did it separate during storage and cause oil-off, making it impossible to obtain a stable emulsion?

The present invention was completed in view of the above-mentioned circumstances, and is a safe and long-term stable O/W emulsion that has even stronger antioxidant power than conventional products. The purpose is to provide antioxidant preparations.

The present invention relates to an emulsion-like antioxidant preparation characterized by containing:

In the present invention, myo-inositol hexaphosphate is used as phytic acid. In addition, tocopherols include naturally concentrated tocopherols and those diluted with fats and oils, and it is also possible to use a-α tocopherol if necessary.

In the present invention, if the amount of tocopherol is less than 1 to 60 weight, the antioxidant power will be insufficient, and if it exceeds 60 weight, emulsification will be difficult. In addition, phytic acid is 0.1 to 40i1
Lit9! +, preferably 1 to 511. If this amount is less than 06lli'1, the antioxidant power will be insufficient, and 4
If it exceeds 0i[4, it becomes difficult to emulsify the oil phase.

As natural gums, commercially available S-algae extracts, seed mucilages, plant secreted mucilages, fruit mucilages, microbial mucilages, starch and its processed products, cellulose mucilages, etc. may be used singly or in appropriate combinations. Although gum arabic, xanthan gum, and gum tragacanth having emulsifying power are particularly preferred, tamarind gum, locust bean gum, and carrageenan can also be used. Natural gum content is 0.01
-50% by weight, preferably 0.2-10 iJl.

If this amount is less than 0.01 by weight, a stable emulsion cannot be obtained, and if it exceeds 50 TIL, it will undesirably turn into a gel.

In addition to the above-mentioned essential ingredients, the emulsion-like antioxidant preparation of the present invention contains K.
L-ascorbic acid, citric acid, gallic acid, etc. can be appropriately blended for the purpose of improving antioxidant power.

In order to obtain the emulsion-like antioxidant preparation of the present invention, the above-mentioned raw materials may be mixed and emulsified using a high-speed stirrer or homogenizer by a known method.

<Effects of the Invention> The emulsion-like antioxidant preparation of the present invention has an extremely strong antioxidant effect, -i, and good emulsification state and stability;
It has excellent water dispersibility, and the oil phase and water phase will not separate even if left at high temperatures for a long period of time.

<Examples> Next, the present invention will be explained with reference to Examples, Comparative Examples, and Trial/Failure Examples. The following coefficients indicate the X quantity coefficient.

Example 1 Oil phase: Natural tocopherol (40% purity product) 4o% (16 t as tocopherol) Aqueous phase: Phytic acid 10 thixan gum 0.5 t water
49.5% The above ingredients were mixed and heated to 65"C.
After heating to °C and adding the 9 oil phase and stirring, the mixture was homogenized using a homogenizer.

Example 2 Oil phase natural tocopherol (80 purity product) 40 degrees (32 degrees as tocopherol) Aqueous phase phytic acid 0.5 degree gum tragacanth 109II water
34.5% An antioxidant preparation was obtained in the same manner as in Example 1 using the above ingredients.

Example 3 Oil phase: a-α tocopherol 10: Water phase: phytic acid 2: Gum arabic 1: citric acid

An antioxidant preparation was obtained in the same manner as in Example 1 using the above ingredients.

In Comparative Examples 1 to 5 below, preparations were obtained in the same manner as in Example 1.

Comparative Example 1 Oil phase: natural tocopherol (40% pure product): 40% water phase: phytic acid: 10% decaglycerin monolacrate: 3% water

59.5 tatami Test Example 1 The emulsions obtained in Examples 1 to 3 and Comparative Examples 1 to 5 were placed in a t-100d measuring cylinder and left standing in a constant temperature bath at 30°C and 60°C for one month to emulsify. I observed the condition. The results are shown in Table 1, and it can be seen that the emulsion stability using natural gum is good.

Table-1 0 indicates water separation force, X indicates complete separation of aqueous phase and oil phase Test Example 2 Examples 1 to 2 where emulsion stability was good in Test Example 1
3 and Comparative Example 4.5, the following tests were conducted.

Seawater in which 0.1% of each antioxidant preparation was dissolved was prepared, and immediately-killed natural seawater was immersed in the seawater to observe changes in color fading (red skin) over time. For comparison, a similar test was also conducted using seawater without any additives. The temperature of the seawater was maintained at around 3"C. The results are shown in Table 2. From the results in Table 2, it can be seen that the example containing tocopherol and phytic acid has a higher antioxidant content than the comparative example book. It can be seen that the effect is excellent, which slows down the fading of the epidermis of the state and preserves its freshness.

◎ is bright red, O is red, Δ is slightly faded,
