JPH1042798A - Lycopene-containing feed and livestock meat or egg containing lycopene - Google Patents

Abstract

PROBLEM TO BE SOLVED: To inexpensively produce a lycopene-containing feed and livestock meat and an egg containing the lycopene at a low cost. SOLUTION: This lycopene-containing feed comprises a dried substance obtained by pressing a lycopene-containing fruit, separating a juice and a residue thereof and drying the separated residue as an active ingredient. The feed for livestock is prepared by initially drying a residue produced when pressing the lycopene-containing fruit, e.g. a tomato fruit and producing a tomato juice according to, e.g. a freeze-drying method, then finely dividing the dried residue with a pulverizing mill, etc., initially producing the finely divided material having a higher content of lycopene than that of the raw tomato fruit, directly mixing the finely divided material with a basic feed or extracting the lycopene ingredient from the finely divided material and mixing the extracted lycopene ingredient with the basic feed. Furthermore, the feed thus produced is administered to livestock to thereby enable the including of the lycopene in the produced livestock meat (pork or chicken) or egg (hen's egg) at a high concentration.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a lycopene-containing feed having an antioxidant action and a carcinogenesis-suppressing action, and to a lycopene-containing animal meat or egg.

[0002]

2. Description of the Related Art Recently, β-
Highly functional foods containing carotene, docosahexaenoic acid, and the like in foods have attracted attention. It is known that β-carotene is abundant in green-yellow vegetables, and it is known that, for example, chickens and eggs can contain β-carotene by feeding non-standard vegetables that cannot be shipped as feed to poultry and raising them. . In addition, it is known that docosahexaenoic acid is contained in fishes in a large amount, and it is also known that docosahexaenoic acid can be contained in pork, for example, by feeding these fishes to livestock.

[0003] Lycopene, which belongs to the carotenoids like β-carotene, has received less attention than β-carotene because it does not have provitamin A activity, but recently it has a strong antioxidant effect. ,
It has been found that it is effective in preventing adult diseases, carcinogenesis and aging (see the monthly publication of Food Chemicals, March 1995, “Carotenoid-Lycopene of which attention is paid to functionality”). We have been working on the development of foods to be included in a lot.

[0004] As shown in Table 1 below, β-carotene is known to be contained in a large amount in natural fruits and vegetables. However, with respect to lycopene, very few fruits such as watermelon, tomato and grapefruit (pink) are used. It is said that it is contained only in vegetables and vegetables.

[0005] nd: Not measured-: Below detection limit

[0006] For this reason, the present inventors also feed non-standard watermelon, tomato or grapefruit to chickens and pigs and investigate the content of lycopene contained in eggs, chicken and pork bred with such feeds. However, almost no lycopene was detected in most of the eggs and meat. This is presumed to be due to the extremely high water content of watermelon, tomato or grapefruit, and the inability of chickens and pigs to consume watermelon or tomato as a staple food, and to consume only a small amount. You.

[0007] Further, it must be said that profitability when actually used as feed is low. So the inventors
Focusing on residues generated during the production of tomato juice, grapefruit juice, etc., we investigate and study whether these can be used as feed, and pork produced and bred based on these feeds Studies were conducted to increase the lycopene content in chicken and eggs.

[0008]

That is, an object of the present invention is to produce lycopene-containing feed and lycopene-containing animal meat and eggs at low cost and at low cost.

[0009]

In order to achieve the above object, a first aspect of the present invention is to squeeze a lycopene-rich fruit and dry the residue separated into a juice and its residue,
The resulting dried product was used as a lycopene-containing feed containing an active ingredient.

[0010] In order to achieve the above object, a second aspect of the present invention is to squeeze a lycopene-rich fruit, dry the residue after squeezing the juice, pulverize the residue, and use the refined lycopene-containing feed. It is what it was.

A third aspect of the present invention is to extract a lycopene-rich feed by squeezing a lycopene-rich fruit, drying the residue after squeezing the fruit juice, and pulverizing the residue. The lycopene-containing animal meat or eggs produced by breeding livestock further.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Tomato juice as fruit juice is
It was produced by squeezing the fruit of tomato, which is a lycopene-rich fruit, using a squeezing and squeezing machine, and tomato residues were generated in large quantities as scum (by-product) after squeezing in the process of producing tomato juice. This tomato residue is mainly composed of fibers, seeds, skins and the like of the flesh, and this residue has conventionally been discarded because it has no value. The present inventors dried this tomato residue by a freeze-drying method, and then refined them using a pulverizing mill or the like, and first produced a refined product. Refinement: average particle size 0.1mm ~ 5
mm. On the other hand, the tomato residue was subjected to a drying treatment, and the resulting dried product was also manufactured.

The inventors first analyzed the components of each of the tomato residue and the refined product and dried product produced using the tomato residue, and as a result, the following results were obtained. First, as a result of analyzing the components of 10 kg of the tomato residue, 90% or more of the residue was also water, and the lycopene concentration in the 10 kg of the tomato residue was 15 mg% (10 kg).
Medium). On the other hand, when 10 kg of the tomato residue was freeze-dried and powdered to produce a powdered product, about 2.2 kg of the dried product or powdered product was obtained, and the lycopene concentration of this was measured. As a result, the lycopene concentration was approximately 55.9.
mg% (in 2.2 kg). The present inventors have analyzed the results of such a large increase in lycopene concentration, and found that lycopene is contained in tomatoes and pulp rather than in juice and pulp in tomatoes, and tomato residues are freeze-dried. As a result of the powdering, it is presumed that the lycopene component contained in the seed and the skin appeared and the concentration was improved. That is, it was confirmed that the concentration of lycopene could be further improved by drying or miniaturizing the tomato residue rather than the tomato residue itself.

[0014] The inventor conducted an experiment in which a dried product or a finely divided product obtained from the tomato residue produced as described above as a raw material was directly mixed with other basic feeds and fed to livestock such as chickens and pigs. Further, the present inventors add an organic solvent (eg, methyl acetate, acetone, alcohol, etc.) to the refined tomato residue as a raw material produced by the above method to produce a lycopene extract (extract), and extract the lycopene. An experiment was also conducted in which the food was mixed with other basic feeds and given to livestock such as chickens and pigs. The lycopene extract obtained by adding an organic solvent may be further purified to increase the lycopene concentration. Further, it was also found that grapefruit fruits and watermelon fruits, which are currently known as lycopene-rich fruits other than tomatoes, can be dried and powdered by the same method to produce a lycopene-containing feed from the raw materials.

[0015]

Example 1 A 220-day-old chicken (Supernick) was used as a test animal, and 110 g of a lycopene-free basal feed was added with 2 g, 4 g and 6 g of freeze-dried pericarp as a test amount per day. Ingestion was continued for a week. 3
After the week, the supply of the peel was stopped, and only the intake of the basal feed was continued for one week. Eggs were collected on the 0th, 7th, 14th, 21st and 28th days after the start of the test, and changes in the amount of lycopene contained in the yolk were tracked.

As a result of the test, 0 (μ)
g / g yolk), it was confirmed that the lycopene concentration in the chicken egg increased with the ingestion of the pericarp-containing sample. In addition, it was also confirmed that there was a tendency that the accumulation was higher in the category in which the blending amount of the pericarp was higher. Furthermore, no lycopene was found in the yolk one week after the ingestion of the pericarp was stopped, confirming that the lycopene in the yolk was derived from the pericarp (FIG. 1). No noticeable change was observed in the amount of ingestion due to the combination of the pericarp, and no significant difference was observed between the control group and the pericarp ingestion group at the end of the test.

[0017]

Example 2 LW piglets of 5 months old were used as test animals.
Four days of continuous ingestion was performed for 10 days of the test feed per day instead of dry peel of tomato residue in a non-pulverized state (Category A). In addition, a category in which the pericarp unblended feed was sampled during the same period was also set (category B). After four weeks of continuous ingestion, the lycopene-containing concentration in the subcutaneous lining fat and the longissimus thoracic muscle was measured and compared between the dry pericarp-combined group and the non-combined group. As a result, the presence of lycopene in subcutaneous lining fat and the longissimus thoracic muscle was confirmed in the piglets of Category A, whereas those in Category B
Was not detected in any of the piglets (Table 2).

[0018]

Example 3 Approximately 10 kg of a tomato residue having a water content of 90% and a lycopene concentration of 15 mg% was freeze-dried and then pulverized to produce a finely divided product of approximately 2.2 kg. The lycopene concentration in this micronized product is 55.9 mg%. An organic solvent such as methyl acetate, acetone, or alcohol is added to the finely divided product, and a lycopene extract is extracted from the finely divided product. The lycopene extract may be further improved in lycopene concentration by means such as distillation. The lycopene extract (for example, oily form) thus produced was first emulsified and blended with a homogenizer as described below.

Further, a binder is added to the above emulsion,
A compound feed containing a lycopene concentration of 56.0 mg as an active ingredient was produced. This compound feed was used as a test in 220-day-old chickens in the same manner as in Example 1 except that the amount was changed to 2 g, 4 g, and 6 g, and the change in lycopene concentration in the yolk collected in the same manner was measured ( See Table 3). As is clear from Table 3, it was confirmed that the higher the test amount, the higher the accumulation of lycopene, as in the above example. (Unit: μg / g yolk)

[0020]

Example 4 A dried powder having a lycopene concentration of 45 mg% was obtained by freeze-drying the squeezed residue generated during the production of grapefruit (pink) juice to reduce the water content to 10% and then subjecting it to micronization. I got In the same manner as in Example 1, this powder was blended with 6 g per day in a basal feed for 220-year-old chickens and ingested continuously for 4 weeks.
Eggs were laid every week during the ingestion period, and changes in lycopene concentration in the yolk were followed up. As a result, as in the case of the dried tomato peel, an increase in the lycopene concentration in the yolk accompanying the ingestion was confirmed (see Table 4), and the coloration of the yolk also increased in proportion to the increase in the amount of accumulated, and the bright yellow color It became.

As described above, according to the present invention, lycopene-containing feed, lycopene-containing animal meat and eggs can be produced at low cost and at low cost by using tomato residues and other lycopene-rich fruit residues made of inexpensive materials. Has the effect that it can be produced.
