Description

Antioxidant composition for pet food and pet food containing same

Technical Field

The invention relates to the technical field of animal feed additives, in particular to an antioxidant composition for pet food and pet food containing the same.

Background

The market for pet food has been on the rise year by year, and has recently been on the rise at a high rate. Since 2004, the domestic pet food industry gradually expands, in 2014, the domestic pet food industry has been increased at a high speed for a long time, the sale scale of the pet food industry is increased from 48 hundred million to about 170 hundred million in 2018, and the composite growth rate is as high as 37.39%. The number of pets in 2014 is increased at a high speed, and as of 2018, 9149 thousands of dogs and cats are in total in cities and towns in China, so that the overall high-speed development of the pet food industry is driven. The market scale of Chinese pet food in 2019 is predicted to break through 700 billion yuan.

With the improvement of GDP and income of per capita in China and the expansion of the middle-yield class, various product markets in China face the consumption upgrade at present, and the method is also applied to the field of pet food. Consumer upgrades represent a long-term trend in the pet food industry, and a core reason for consumer upgrades for pet food is the pursuit of health.

Grease is one of three main nutrient substances in nature, and plays an important role in pet food, and is one of five main nutrient elements of the pet food. The amount of fat is indispensable in pet food. Fat itself is also a constituent of pet milk, body flesh, sperm and fur. In recent years, polyunsaturated fatty acids are widely applied to functional pet foods, and a certain proportion of polyunsaturated fatty acids or food materials with high content of unsaturated fatty acids are added into cat and dog foods with a plurality of professional formulas. However, oils and fats, particularly oils and fats containing highly unsaturated fatty acids, are easily oxidized to produce various harmful substances such as aldehydes and acids, which cause deterioration of products and thus harm the health of pets. Therefore, improvement of the stability of fats and oils is an important issue for healthy pet foods.

The mint extract is derived from natural mint leaves, is rich in various phenolic substances, and has potential in the field of oxidation resistance. The commonly used mint extract is mainly used for producing menthol and dementholized peppermint oil at present, and is mostly applied to the medicine and food industries because of the special effects of aroma, cool feeling, wind dispelling, pain relieving, stomach strengthening and the like.

Vitamin E is a fat-soluble vitamin, the molecular structure of the vitamin also contains a phenolic structure, so that the vitamin E has corresponding antioxidant capacity, and the vitamin E is also the most commonly used antioxidant in pet foods at present, but the loss of the vitamin E in the processing of some pet foods is more, and the antioxidant effect is easily influenced.

The main components of rosemary extract are rosmarinol, carnosol and carnosic acid. The main components in the rosemary extract have strong antioxidant activity. Has obvious effects on preventing the oxidation of grease, maintaining the flavor of meat and the like, and is also a common natural antioxidant.

Butyl hydroxy anisole, abbreviated as BHA, is also a high-efficiency antioxidant, and compared with the three natural antioxidants, the butyl hydroxy anisole is a synthetic antioxidant and has some disadvantages in safety, so that the addition amount needs to be strictly controlled during application.

The four substances are all effective antioxidants and can effectively inhibit the oxidation of grease, and from the prior documents, the following three antioxidant effects are more researched, such as patent 201310503453.1 and 201410523334.7, and a small amount of research relates to a composition containing two or more of them, such as 201510068555.4 and 201110077334.5. However, to date, no studies have been made on the antioxidant activity of mint extracts in pet foods, and in particular, mint extracts have been found to non-selectively increase the antioxidant activity of other antioxidants, including both natural antioxidants such as tocopherol, rosemary extract, and synthetic antioxidants such as BHA. The present inventors have conducted extensive studies and have finally found an efficient and economical antioxidant composition for pet food containing a mint extract, and have completed the present invention.

Therefore, the conventional antioxidant for pet food has inconvenience and disadvantages in use, and needs to be further improved. In order to solve the problems of the conventional antioxidant for pet food, related manufacturers have tried to solve the problems without worry, but it has not been known that suitable designs are developed and completed for a long time, and no suitable product can solve the problems, which is obviously a problem to be solved by related manufacturers.

In view of the above-mentioned disadvantages of the conventional antioxidant for pet food, the present inventors have made extensive research and innovation based on practical experience and professional knowledge of many years in designing and manufacturing such products, and in cooperation with the application of theory, in order to create a novel antioxidant composition for pet food and pet food containing the same, which can improve the conventional antioxidant for pet food and make it more practical. After continuous research and design and repeated trial and improvement, the invention with practical value is finally created.

Detailed Description

The present invention will be further described below by way of specific embodiments, but the present invention is not limited to only the following examples. It will be apparent to those skilled in the art that the invention can be modified and replaced with other components having the same effects without departing from the spirit and scope of the invention, and all such modifications and substitutions are deemed to be within the scope of the invention.

Example 1 antioxidant composition of the invention

20 parts of mint extract and 80 parts of vitamin E.

Example 2 antioxidant composition of the invention

15 parts of mint extract and 85 parts of rosemary extract.

Examples 3,Antioxidant composition of the invention

20 parts of mint extract, 60 parts of vitamin E and 20 parts of rosemary extract.

Example 4 antioxidant composition of the invention

5 parts of mint extract and 95 parts of BHA.

Test example one, efficacy test of the composition of example 1 in pet food fat

The compositions of example 1 were compared to vitamin E alone and peppermint extract alone, respectively, and tested for their antioxidant capacity in chicken fat. The POV and OSI results are shown in FIGS. 1 and 2 (blank is chicken fat, no antioxidant is added, vitamin E is added at 500ppm, peppermint extract is added at 500ppm, and peppermint extract + vitamin E complex antioxidant is added at 500 ppm).

The peroxide value reflects the degree of oxidation of the oil, the higher the value the more severe the oxidation of the oil. From the results in fig. 1, it can be seen that the blank oxidation rate and extent are the most severe, followed by the addition of 100ppm of mint extract alone, with a single mint extract showing significantly less antioxidant than vitamin E, while the addition of the mint extract with a complex antioxidant has significant advantages, as also demonstrated in OSI's experiments. The OSI test is the lead time before oxidation of the test grease, and longer time indicates more stable grease. It can be seen from fig. 2 that the complex antioxidant supplemented with mint extract has the longest induction time and thus the best antioxidant effect, followed by vitamin E. Through two experiments of POV and OSI, the mint extract can obviously and synergistically increase the antioxidant effect of vitamin E although the antioxidant capacity of the mint extract is not strong.

Test example two, efficacy test of the composition of example 2 in pet food fat

The composition of example 2 was compared to rosemary extract and tested for their antioxidant capacity in chicken fat. The POV and OSI results are shown in FIGS. 3 and 4 (blank is chicken oil, no antioxidant is added, rosemary extract is added at 500ppm, peppermint extract + rosemary extract complex antioxidant is added at 500 ppm).

As can be seen from fig. 3 and 4, the mint extract also significantly improves the antioxidant property of the rosemary extract, showing a good synergistic effect.

Test example three, efficacy test of the composition of example 3 in pet food fat

The antioxidant capacity of the composition of example 3 was measured in chicken fat in comparison to a complex of vitamin E and rosemary extract. The POV and OSI results are shown in FIGS. 5 and 6 (blank is pure chicken oil, no antioxidant is added, vitamin E and rosemary extract are compounded in a ratio of 3: 1, the addition amount is 500ppm, and the addition amount of the mint extract + vitamin E + rosemary extract complex antioxidant is 500 ppm).

From fig. 5 and 6, it can be seen that the mint extract has a significant synergistic effect even though it is a complex antioxidant for vitamin E + rosemary extract.

Test example four, efficacy test of the composition of example 4 in pet food fat

The composition of example 4 was compared to BHA and tested for its antioxidant capacity in chicken oil. The POV and OSI results are shown in FIGS. 7 and 8 (blank is pure chicken oil, no antioxidant is added, BHA is added at 200ppm, peppermint extract + BHA complex antioxidant is added at 200 ppm).

As can be seen from FIGS. 7 and 8, even though the mint extract was added in an amount of only 5%, it could greatly improve the oxidation resistance of BHA.

In conclusion, the pet food comprising such an antioxidant composition according to the invention does not reduce the palatability for pets compared to a pet food not comprising such a composition. An extract of peppermint containing a specific amount of molecules as claimed can enhance the bioavailability of these molecules compared to the bioavailability obtained when added alone. Advantageously, the bioavailability is synergistically enhanced. Through comparative tests on the oxidation resistance of the compositions, the mint extract has weak oxidation resistance, but can obviously and synergistically increase the oxidation resistance of other substances, and shows good synergistic effect.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
