Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an emulsion-like antioxidant preparation for use in processed marine foods and the like. BHA (butylated hydroxyanisole) has traditionally been used to prevent oxidation in processed seafood foods, but safety has been raised as a problem, and administrative measures have recently been taken to ban its use in foods. For this reason, there has been a strong desire to develop a safe antioxidant to replace BHA. Antioxidants used in processed seafood foods are generally used by dissolving them in the fish soaking liquid or kneading them into minced fish, so they must have very good water solubility or dispersibility in water. Since sufficient antioxidant ability cannot be obtained, oil-soluble antioxidants such as tocopherols cannot be used unless they are emulsified with water. However, emulsifying only tocopherols does not have sufficient antioxidant ability and requires the addition of a considerable amount to achieve the desired effect, which is disadvantageous from an economical and other point of view. . The purpose of the present invention is to improve the low antioxidant ability of tocopherols as described above, and to formulate them into a milky lotion preparation. The present inventors noticed that the antioxidant ability of tocopherols was significantly improved by adding gallic acid and L-ascorbic acid to tocopherols, and as a result of various studies on these emulsions, the present invention was developed. Completed the invention. Both gallic acid and L-ascorbic acid are acidic substances that make it difficult to emulsify tocopherols, but it was found that a milky lotion with good emulsification can be obtained by using monoglyceride as an emulsifier, which led to the realization of the present invention. made it possible. That is, the present invention contains tocopherol 1 to 40% by weight (hereinafter % indicates weight), gallic acid 0.1 to 5%,
The present invention provides an emulsion-like antioxidant preparation whose main components are 0.1-5% L-ascorbic acid, 20-95% water, and 0.2-5% monoglyceride. In the present invention, a mixture of the essential components of tocopherol, gallic acid, L-ascorbic acid, water, and monoglyceride in the above proportions has a significantly high effect of tocopherol as a water-dispersible antioxidant and has high emulsion stability. In good condition. Outside the above blending range, either the antioxidant effect is insufficient or the emulsion stability becomes poor. The tocopherols used in the present invention are commonly commercially available products such as naturally concentrated tocopherol, diluted with oil and fat, δ-tocopherol concentrated from natural tocopherol, and dl-α tocopherol, which may be used alone or They can be used in appropriate combinations. Furthermore, the monoglycerides used in the present invention include glycerin fatty acid monoesters such as stearic acid monoglyceride and oleic acid monoglyceride, organic acid monoglycerides such as citric acid monoglyceride, succinic acid monoglyceride, and diacetyl tartaric acid monoglyceride, and the like. , or can be used in appropriate combination. In addition to the essential components of tocopherol, gallic acid, L-ascorbic acid, water, and monoglyceride, the emulsion antioxidant preparation of the present invention also contains oil (for the purpose of diluting tocopherol), gum (emulsifying ), BHT (dibutylhydroxytoluene: antioxidant), etc. can be blended as appropriate depending on the purpose. In order to obtain the milky antioxidant formulation of the present invention, these raw materials may be mixed and emulsified using a high-speed stirrer or homogenizer by a known method. The emulsion-like antioxidant preparation of the present invention has an extremely strong antioxidant effect, and since the emulsification state of the emulsion is good, it is quickly dispersed, and is particularly effective in preventing browning of the product when used in processed marine products such as dried sardines. It is also effective in preventing the oxidation of general foods. Next, examples of the present invention will be shown. Example 1 Oil phase (% by weight) Natural tocopherol (40% purity) 40 Citric acid monoglyceride 2 Aqueous phase L-ascorbic acid 2 Gallic acid 1 Xanthan gum 0.05 Water 54.95 Water in which xanthan gum was dissolved was heated to 65°C. Then, gallic acid and L-ascorbic acid were mixed, and the oil phase, which had been mixed and dissolved at 65℃ in advance, was mixed and stirred, and then heated using a homogenizer (pressure 180℃).
Kg/cm ² ), homogenized, and then cooled to 10° C. to obtain an emulsion-like antioxidant preparation with the above formulation. This one is 5
℃, room temperature, and 35℃ for one month, the emulsification state was good at all temperatures, and it was well dispersed in water. Example 2 Oil phase (% by weight) dl-α tocopherol (98% purity product) 20 Rapeseed oil 20 Diacetyl tartrate monoglyceride 1.5 Aqueous phase L-ascorbic acid 3 Gallic acid 2 Xanthan gum 0.1 Water 53.4 Antioxidant emulsion with the above formulation A formulation was obtained in the same manner as in Example 1. This product is 1 at 5℃, room temperature, and 35℃.
Even after standing for several months, the emulsification state was good at all temperatures and it was well dispersed in water. Example 3 Oil phase (weight %) dl-α tocopherol (as above) 3 BHT 10 Soybean oil 20 Diacetyl tartaric acid monoglyceride 1 Oleic acid monoglyceride 0.5 Water phase L-ascorbic acid 2 Gallic acid 0.5 Gum arabic 5 Water 58 Above formulation An emulsion-like antioxidant preparation was obtained in the same manner as in Example 1. This product is 1 at 5℃, room temperature, and 35℃.
Even after being left standing for several months, the emulsification state was good at all temperatures and it was well dispersed in water. Comparative formulation example 1 Oil phase (wt%) dl-α tocopherol (as above) 20 Rapeseed oil 20 citric acid monoglyceride 2 Aqueous phase xanthan gum 0.05 Water 57.95 Comparative formulation example 2 Oil phase (wt%) dl-α tocopherol ( 20 Rapeseed oil 20 Citric acid monoglyceride 2 Water phase L-Ascorbic acid 5 Xanthan gum 0.05 Water 52.95 Comparative formulation example 3 Oil phase (wt%) dl-α-tocopherol (Previous) 20 Rapeseed oil 20 Citric acid monoglyceride 2 Aqueous phase gallic acid 5 Xanthan gum 0.05 Water 52.95 In this formulation, since there is no L-ascorbic acid, gallic acid reacts with iron ions to develop a dark purple color, reducing the commercial value. Comparative formulation example 4 Oil phase (wt%) dl-α-tocopherol (mentioned above) 20 Rapeseed oil 20 Aqueous phase L-ascorbic acid 3 Gallic acid 2 Xanthan gum 0.1 Water 54.9 In this formulation example, monoglyceride as an emulsifier is blended. Since the emulsification state is unstable,
Two days after preparation, the oil phase separated. Example 4 Put 5g of the emulsion-like antioxidant preparation obtained in Example 1 into a pot filled with water, bring to a boil, then add 0.5kg of washed Japanese sardines (about 7cm long) and boil for 5 minutes. Dry the boiled material with warm air at 40℃,
I got dried sardines. The emulsion-like antioxidant preparations of Example 2, Example 3, Comparative Formulation Example 1, Comparative Formulation Example 2, and Comparative Formulation Example 3 were also trial-produced using the same method in the same manner. At the same time, we also produced a trial version of dried sardines without the addition of antioxidants, stored them at room temperature, and observed the degree of browning due to oil burn over time. The results were as shown in Table-1. In addition, in Comparative Formulation Example 3, the water in the pot was slightly colored dark purple. 【table】
