Problems solved by technology

The solvent extraction method is unsafe, and the equipment investment of the supercritical extraction method is relatively large, and the existing cold pressing method to extract okra seeds also has the following problems: 1) the oil yield is low, and the oil yield is only about 10%; 2) the cotton The phenol content is high, generally around 0.4%; 3) the colloid of okra oil (okra contains more viscous substances such as pectin and polysaccharides) has a high content, which affects the storage stability of the product, etc.
Therefore, when used directly as feed, the nutritional value is not as good as soybean meal, which limits its application

Embodiment 1

[0032] 1. Prepare okra oil

[0033] 1) Harvesting okra seeds

[0034] Take the brown, cracked and fully mature fruit pods of the husk, and after drying or drying, they can be mechanically threshed by an improved nail-toothed corn thresher.

[0035] 2) drying

[0036] Okra seeds pass through the dryer (L=15m, The inlet temperature is 100°C, the outlet temperature is 40°C), and the moisture is lower than 13%.

[0037] 3) Featured

[0038] Impurities and moldy seeds are removed by wind screening, gravity separation and color separation.

[0039] 4) Shelling

[0040] Use a camellia seed sheller to peel the shells.

[0041] 5) Separation of shell and kernel

[0042] The separation of shell and kernel is realized by blower separator.

[0043] 6) cold pressing

[0044] The peeled oilseeds are cold-pressed once with a double-screw cold press to obtain crude oil I and seed meal. Seed meal.

[0045] The double-screw cold press adopts the double-screw oil press from Wuhan Foo...

Embodiment 2

[0070] Embodiment 2: feed feeding experiment

[0071] This experiment was carried out at the laying hen farm in Huaiyang County. 300 180-day-old Hai-Line brown layer hens were randomly selected as feeding objects, and they were divided into two groups, namely the test group and the control group, with 150 chickens in each group, 3 replicates in each group, and 50 chickens in each replicate. The feed formulations of the control group and the test group are shown below, and other management measures are the same. The test was carried out for 35 days, and 15 days after the start of the test, the egg production was counted for each repetition in each group, and the statistics were continued for 20 days to calculate the egg production rate. In the last 10 days of the experiment, 20 eggs were collected for each repetition in each group, and the egg quality was determined.

[0072] Conventional laying hen feed for the control group: corn 58.4%, wheat bran 3%, soybean meal 28%, calc...

Embodiment 3

[0079] Step 11) Add sesamin and vitamin E to the refined edible oil according to the mass ratio of 100:0.5:1.5, and stir evenly to obtain a finished oil, and the remaining steps are the same as in Example 1. The shelf life reaches 6 months.

Abstract

The invention discloses a method for producing okra seed oil, compound feed and fungal matrix by processing of okra seeds. According to the method, the okra seed oil is produced by twice cold pressing, degumming, decoloring, deodorizing and dephenolizing; okra dregs are subjected to cooking detoxification and microbial fermentation and then compounded with eupolyphaga scraps to produce the compound feed; okra seed shells are compounded with calcium superphosphate, urea and gypsum powder to prepare the fungal matrix through fermentation, so that complete replacement of cotton seeds for production of high-performance products including the okra seed oil, the compound feed and the fungal matrix can be realized. By adoption of a twice double-helix cold pressing process, the oil yield is up to 18-20%, and the produced compound feed is larger than or equal to 45% in crude protein content, larger than or equal to 0.27% in calcium and larger than or equal to 26% in total content of amino acids. By the process, components such as pectin and gossypol in the okra seeds can be removed completely.

Description

technical field [0001] The invention relates to a method for processing okra seeds, in particular to a method for processing okra seeds to produce okra oil, compound feed and fungus substrate, and belongs to the field of agricultural technology. Background technique [0002] Cottonseed has always been an important source of edible oil, feed and edible fungus substrate, but with the promotion and planting of transgenic insect-resistant cotton, cottonseed can no longer be used for oil extraction, feed (seed meal) and edible fungus substrate (seed shell) , and new materials are urgently needed to replace them. Okra and cotton belong to the Malvaceae family, with high yield, rich nutrition, light pests and diseases, less medication, non-GMO, green and healthy, and it is the best crop to replace cottonseed. Okra seeds not only contain more iron, potassium, calcium, manganese and other mineral elements, but also can provide oil and protein. Its oil content is as high as about 20%...
