Truthalishenin phenol (TBHQ) is a relatively wide antioxidant in the market. Pet foods are processed and stored in the process of oil, protein oxidation and acid failure, thereby reducing the shelf life of pet food, and how to relieve the oxidation problem of processing storage processes is also needed.

Zhao Qiao et al. Found that the addition of TBHQ has a good antioxidant effect on the oily in the pet food, and the antioxidant effect of vitamin E is 0.05% of the added amount is 0.02% TBHQ. Xie Ronghui studied that there were more unsaturated fatty acids in the fish pet food, more susceptible to fat oxidation, and the addition of TBHQ can delay oxidation, it is an excellent antioxidant.

Trudyl phenol (TBHQ)

1. Solubility: soluble in ethanol (100% at 25 ° C) and diethyl ether; soluble in fat, such as corn oil, soybean oil, cottonseed oil, 20 ° C is 10%; difficult to dissolve in water (less than 1 20 ° C %, 95 ° C 5%). Melting point 126.5-128.5, boiling point 295 ° C. In the case of iron, copper is not discolored, but if there is a base, there is a change in pink.

2. Standard: "GB 26403 Food Safety National Standard Food Additives Titilantine Adenol".

3. Sensory requirements: white crystalline powder with special odor.

4. Phhemism requirements

5. Performance

The TBQH antioxidant properties are superior to effectively delay oil oxidation, improve the stability of food, and have stronger antioxidant resistance than BHT, BHA, PG and vitamin E. TBHQ has a good "carrying into the food" in the fried process (playing with grease into food), but this effect is poor in the food bake, it can improve this property when mixed with BHA. BHA, BHT has no strong effect on unsaturated vegetable oil, but TBHQ exhibits a good antioxidant effect, which is particularly effective for cottonseed oil, soy oil, safflower oil. TBHQ is high temperature, can be used in instant noodles, pastries and other fried foods, the maximum endurance temperature can reach 230 ° C.

In addition to antioxidation, TBHQ has certain antibacterial effects, which can effectively inhibit Bacillus, Golden Colored Staphylococcus, E. coli, and Microbials such as Nishi, Maki Mika, Mito Merci, and Washiang. For bacteria, the minimum inhibitory concentration of yeast is 0.005% -0.01%, which is 0.005% -0.028% to mold. NaCl has a synergistic effect on its antibacterial effect. The TBHQ is strong under acidic conditions, such as the pH of the deformation bacilli equal to 5.5, 0.02% TBHQ is fully inhibited, and at a pH equal to 7.5, 0.035% cannot be fully inhibited.

TBHQ application method

Direct method

Stable fat, oil or wax heating at least 60 ° C, thoroughly stirred to dissolve the antioxidant. It is then sustained to stir (do not have to vigorously stir to avoid excessive air into the infiltration) 20-30 minutes to ensure uniform distribution of antioxidants.

2. Concentrate addition method

The antioxidant concentrated solution can be formulated in a small amount of fat or oil heating to 90-120 ° C. The heated concentrated solution or preformed antioxidant complex liquid can be added directly or in a meter to fat or oil. Then stir, the antioxidant can be evenly distributed.

3. Proportional Method

Antioxidant grease concentrate or prefabricated antioxidant complex liquid, by meter (quantitative pump), injects the fixed flow rate, the flow of fat or oil, which is stable, the flow rate, the flow rate, the flow of the flow of the flow, and the pipe. This work is determined whether or not the turbulence generated when the oil flow in the pipe is sufficiently distributed completely to completely distribute antioxidants.

4, injection method

Some foods can be sprayed on the surface directly with a diluted antioxidant solution. The concentration of the solution can be prepared according to various types of food requirements, and it is also important to ensure that it is uniformly distributed in the surface of the product.

5, other methods

For example: sausages, bacon, etc., can be processed in these salts together by fitting antioxidants to seasonings in order to effectively stabilize food. The fish can also be mixed together, and the squid should be used in white wine, high beam wine, can be dissolved in white wine, and then smear, then apply it to prevent corruption. The ham should use the wax seal to prevent corruption, but it will still be oxidized together for a long time, and the antioxidant should be dissolved in the wax, and the surface of the ham is applied, and the effect can be enhanced, and the oxidant can be blended into the package. It is protected.

Security Analysis of TBHQ

As far as the published research report, the total situation of TBHQ is much greater than the security and reliability of BHT and BHA. As in some environments, experiments have shown that BHT and BHA have a carcinogenic effect on animals, while TBHQ only has suspicious caused mutant activity. There are several aspects below to express their safety:

Absorption, metabolism and excretion

The death of the mouse, dog and human oral TBHQ is basically the same, so the mouse is experiment. Experiments prove that the absorption of the digestive tract and the rapid discharge from the urine. If you take a 1-400 mg / kg of TBHQ, most of them are discharged from the urine within 2-4 days. The person was given 200 mg / kg (with 30% corn oil as a carrier), and most of the doses were discharged from urine within 2-3 days. Long-term feeding is not significantly accumulated in the organization.

2. Influence of liver

After short-term trials, BHA and BHT have a significant impact on the liver, resulting in high liver, and under the same conditions, TBHQ has no significant effect on the liver.

3. Influence on reproduction

A few reproductive research in mice, the published reports include the study of distortion of the three-generation reproduction process. In a generation of reproductive processes, TBHQ is administered in the organ formation stage, and the effect of its aberration is studied, and the amount of TBHQ is 5000 mg / kg, that is, 250 mg / kg daily, and the results did not find any distortion phenomenon.

4. Long-term case of cancer research

When the mouse is a rat, 0, 160, 500, 1600 and 5000 mgtbhq / kg are quantified, 20 months, no abnormal phenomena, including hematology, clinical chemistry, urine analysis, organ weight and tissue disease The observation of the science.

In the study of dogs, the dose is 0,500, 1500 and 5000 mgtbhq / kg, quantitatively feeding 117 weeks, there is no abnormal situation according to the prescribed blood test, but when using the highest dose, erythrocyte count, heme and red ball The proportion is less than the control test, which seems to show that TBHQ has some destructive effects on red blood cells.

End of 2500 mg / kg, quantitative taking 9 days, no effect, increase the dose to 10,000 mg / kg, there are some cell proliferation, but the original number increased by 50%, but the same situation, BHA increased by 350%, in the same In the short-term experiment, feeding is 20000mg / kg, found that the front gastric mucosa has a slight hyperplasia, but in the same study, BHA has a more significant impact on the front stomach.
