Description
Technical Field
The invention relates to the technical field of feeds, in particular to the technical field of yellow mealworm feeds.
Background
Yellow mealworm is a species of Insecta, Coleoptera, Palmaceae and Trionychus, and is the most ideal feed insect for artificial breeding. The larva of the yellow mealworm contains various saccharides, amino acids, vitamins, hormones, enzymes and mineral substances such as phosphorus, iron, potassium, sodium, calcium and the like besides high crude protein and fat content, has high nutritional value, can be directly used as living animal protein feed for feeding frogs, turtles, scorpions, centipedes, ants, high-quality fishes, ornamental birds, medicinal animals, precious fur animals, rare livestock and poultry and the like, and is the first living animal protein feed for various living animals due to high protein nutritional ingredients.
Although the tenebrio molitor serving as the animal protein feed can meet the protein intake requirement of a culture product, the trace elements are also necessary nutrient elements of the culture product, and the traditional tenebrio molitor protein feed cannot meet the requirement of the culture product on the trace elements. Although the common means in the feed industry is to directly add corresponding trace element additives, the adding mode of the trace elements has extremely low absorption rate, and the trace element discharge amount in the production process also causes burden to the environment; and the taste is influenced, the microelements and various nutrient substances in the feed are easy to react with each other, and the nutrient titer is reduced
Disclosure of Invention
The invention aims to provide a tenebrio molitor protein feed rich in various trace elements and a preparation method thereof, so that the problem of insufficient trace element content of the traditional tenebrio molitor protein feed is solved, the total addition amount of the trace elements in the feed can be reduced, the discharge amount of the trace elements is reduced, and the environment is protected.
The invention provides a defatted tenebrio molitor protein feed rich in various trace elements, which is tenebrio molitor protein powder rich in trace elements prepared from tenebrio molitor;
the trace elements comprise one or more of iron element, copper element, manganese element, zinc element, selenium element, iodine element and cobalt element.
Further, the form of the iron element is ferrous fumarate or/and ferrous glycinate.
Further, the copper element is in the form of copper sulfate or/and copper oxychloride.
Further, the manganese element is in the form of manganese sulfate or/and manganese carbonate.
Further, the zinc element is in the form of zinc methionine or/and zinc sulfate.
Further, the form of selenium element is sodium selenite.
Further, the element of the iodine element is potassium iodate or/and calcium iodate.
Further, the cobalt element is in the form of cobalt sulfate or/and cobalt chloride.
A preparation method of degreased yellow mealworm protein feed rich in various trace elements comprises the following steps:
(1) feeding yellow mealworms, namely feeding prepared insect feed rich in trace elements from yellow mealworms of 10 days old for 70-80 days;
(2) screening yellow mealworms, and removing insect feces and residual insect feed;
(3) drying by microwave to obtain dried yellow mealworms with the water content of less than 8%;
(4) removing fat from the dry tenebrio molitor by a carbon dioxide supercritical extraction method to obtain crude protein powder with fat content of below 6%;
(5) dissolving the powder after removing impurities, and filtering to remove insoluble impurities;
(6) spray drying to obtain tenebrio molitor protein powder rich in trace elements;
(7) adding anticaking agent to obtain final product.
Preferably, the first and second electrodes are formed of a metal,
the content of the trace elements in the insect feed in the step (1) is 0.5-1% by mass;
the extraction parameters in the step (4) are 50Mpa,50 ℃ and 75-80 min;
the dissolving process of the crude protein powder in the step (5) is as follows: adding the crude protein powder into distilled water to form crude protein liquid, and adding sodium chloride into the crude protein liquid to fully dissolve the protein.
Compared with the prior art, the invention has the following advantages:
the prepared tenebrio molitor protein powder can be used for compound edible protein powder and health-care products, can also be used for livestock and poultry breeding, can greatly improve the absorption efficiency of each trace element while providing high-quality protein, and reduces various negative effects of direct additives of each trace element in feed processing; in addition, the oil extraction parameters are optimized, the oil content of the protein powder can be reduced to the lowest as possible, the possibility of deterioration and peculiar smell of the protein powder in a short period is reduced to the lowest, the shelf life is prolonged, and the product quality is ensured; the extraction process does not need high-temperature treatment, protein is not denatured, the problem of nutrient loss is not caused, and the flavor and the taste can be kept unchanged.
