Description

  The present invention relates to a dog food.

  Currently marketed pet foods can be classified into several types according to the water content contained. That is, a dry type with a water content of about 10% or less, a soft dry type with a water content of about 20 to 40% and a semi-moist type, and a wet type with a water content of about 70% or more (for example, canned foods ). Among them, the dry type, soft dry type, and semi-moist type pet foods have become mainstream pet foods because the nutritional balance is easy to adjust, mass production is possible, and production and distribution costs are low. However, in general, pet food with a low water content has a problem of low palatability.

Various attempts have been made to improve the taste of pet food. For example, a method of adding a lipase degradation product or protease degradation product of milk or a milk processed product (Patent Document 1), a method of adding theanine which is an umami component of green tea leaves (Patent Document 2), a method of adding a yeast extract ( Patent Literature 3), a method for scorching fish paste products (Patent Literature 4), a method for adding acetic acid and honey (Patent Literature 5), and the like are disclosed. In order to improve the palatability of dog food, animal fats and visceral extracts have been conventionally blended and coated on the surface of the grains.

  The present invention will be further described below using examples.

Confirmation of palatability The palatability was confirmed using a biscuit-like solid feed that was baked by blending flour, corn gluten, chicken, rice and cananol oils and coated with a maple syrup solution. Maple syrup (trade name: QUEBEC GRADE # 2 AMBER, manufactured by Citadelle) 15% (w / v), maple flavor (trade name: NATURAL MAPLE TYPE FLAVOUR 2B6A007, manufactured by BSA) 2% on the surface of the solid feed An experimental group was prepared by coating a maple syrup solution consisting of w / v), maltodextrin 15% (w / v) and water 68% (w / v) at a rate of 10 wt%. Moreover, the thing which does not coat the said solid feed was made into the control group.

  Samples from the experimental group and the control group were given to 20 subjects (beagle dogs) once a day, 150 g each, and observed for 2 days. On the first day, the control group sample was set on the left side, and on the second day, the experimental group sample was set on the left side. Salary time was 20 minutes, and if either sample disappeared before that time, it was terminated at that point. The results of summarizing the sample amount taken by each subject are shown in Table 1 below. In the first and second results in Table 1 below, the sample that the subject first started eating is shown in bold.

  As shown in Table 1 above, the intake of the sample was experimental group: control group = 94: 6, and the intake of the experimental group sample was very large. In addition, the sample that the subject first started eating was also overwhelmingly the sample in the experimental group. Therefore, it can be said that the palatability of dogs was significantly improved by coating the solid feed with the maple syrup solution.

Confirmation of palatability A biscuit-like solid feed similar to that in Example 1 was coated with a coating solution composed of various components, and samples from the 1st to 8th experimental groups containing the components shown in Table 2 below were prepared. Sample 1 is a sample to which components other than water are not added, and sample 2 is a sample to which 1.5 wt% maple syrup, 0.2 wt% maple flavor and 1.5 wt% maltodextrin are added, The sample in Section 3 is a sample to which 0.375 wt% maple syrup, 0.05 wt% maple flavor and 1.5 wt% maltodextrin are added, and the sample in Section 4 is 1.5 wt% maple syrup and 0.2 wt% % Maple flavor was added, 5 samples were 1.0 wt% sucrose and 1.5 wt% maltodextrin, and 6 samples were 1.0 wt% sucrose. Is added to the sample, and the 7th sample is added with 1.5wt% maple syrup. The is a sample, a sample of the 8th arrondissement, is a sample of 0.2wt% maple flavor is added.

  Using the experimental group samples in Table 2 above, palatability tests (Test Nos. 1 to 7) were performed with combinations shown in Table 3 below. That is, test no. In test No. 1, test No. 1 and test No. 2 were tested. In No. 2, the 1st and 3rd wards were designated as Test No. In No. 3, the 1st and 4th wards were designated as Test No. In No. 4, the 1st and 5th wards were designated as Test No. In No. 5, the 1st and 6th wards were designated as Test No. In No. 6, the 1st and 7th wards were designated as Test No. 7 compared 7 and 8 wards.

  In each test, 2 samples of the combination were given to 5 subjects (beagle dogs) once a day, 250 g each, and observed for 2 days. On the first day, one sample was set on the left side, and on the second day, the other sample was set on the left side. The salary time was 20 minutes, and it ended when either sample disappeared before that time. The results of summarizing the average intake of samples in each test are shown in Table 3 below.

  Test No. in Table 3 above. As shown in 1 to 3 and 6, it was confirmed that the palatability of dogs was increased by including maple syrup in the solid feed. In addition, Test No. 1 to 3 and test no. As compared with 6, it can be confirmed that the addition of maple flavor to the maple syrup further enhances the palatability, for example, synergistically. On the other hand, test no. From Fig. 7, it can be confirmed that maple syrup contributed to the improvement of palatability than maple flavor. Furthermore, test no. 1-3, 6 and test no. Compared with 4, 5, it can be confirmed that maple syrup can enhance palatability than sucrose. Furthermore, test no. 1 and test no. 3 and test no. 4 and test no. From the comparison with 5, it was recognized that palatability improved when maltodextrin was not added.

Influence on blood glucose level The samples of 1st, 4th, 6th and 7th prepared in Example 2 were used, and blood glucose levels before and after feeding these samples were measured. As described above, the first sample is a sample to which components other than water are not added, and the fourth sample is a sample to which 1.5 wt% maple syrup and 0.2 wt% maple flavor are added, The sample is a sample to which 1.0 wt% sucrose is added, and the sample in Section 7 is a sample to which 1.5 wt% maple syrup is added.

  The above 4 samples were fed at 250 g / day using 3 healthy beagle dogs as subjects, blood was collected immediately before feeding, 30 minutes after feeding, 1 hour and 2 hours later, and blood glucose level was measured. FIG. 1 shows the result of averaging the change in blood glucose level based on the blood glucose level immediately before salary. As shown in FIG. 1, in the 6 ward samples containing sucrose, the increase in blood glucose level was remarkable 1 hour after feeding, but in the 4 ward and 7 ward samples containing maple syrup, the increase in blood glucose level was suppressed. It was. In these samples, it can be determined that the rate of increase in blood glucose level is moderate.

As described above, the present invention is useful, for example, in the field of pet-related industries and the field of pet food.

FIG. 1 is a graph showing an example of a result of measuring blood glucose levels before and after sample feeding.
