Description

Technical Field

[0001] This invention relates to the field of organic sulfur preparation and application technology, and in particular to a method for preparing organic sulfur oil for aquaculture and crop cultivation and its application. Background Technology

[0002] Sulfur is an element in Group VIA of the periodic table. Its elemental form is a yellow solid at room temperature, but at high temperatures, it is highly reactive, reacting with almost all metals except gold and platinum to form sulfides. In nature, sulfur exists primarily as glassy native sulfur or as sulfides bound to heavy metals, such as pyrite (FeS2), galena (PbS), zinc pyrite (ZnS), and chalcopyrite (CuFeS2), as well as sulfates like anhydrite (CaSO4) and gypsum (Ca(SO4)2·H2O), and as hydrogen sulfide (H2S), sulfur dioxide (SO2), and sulfuric acid (H2SO4) in volcanic gases, hot springs, and mineral springs.

[0003] Furthermore, sulfur is the fourth most abundant mineral in the human body, after calcium, phosphorus, and potassium. It can be found in all cells of the body and is a component of important amino acids (including cysteine, cystine, and methionine), essential for cellular life. It is also a component of vitamin B1 and biotin, and is present in saliva, bile, and insulin. Sulfur accounts for 0.15% of body weight and 10% of the body's total mineral content. Therefore, sulfur is one of the most important substances indispensable for metabolic activities such as respiration and metabolism in living organisms.

[0004] However, humans can only directly ingest sulfur in the form of organic sulfur indirectly produced from plants or animals. Inorganic sulfur is extremely thermotoxic and can be life-threatening if ingested directly. Therefore, sulfur is sometimes introduced by feeding sulfur-containing feed to specific animals, who then consume the meat. However, this method is only suitable for certain animals. In recent years, attempts have been made to use methods that incorporate sulfur with minimal toxicity to feed poultry or livestock, which humans then consume. However, even when sulfur-containing compounds are made into powder, if the amount of sulfur added cannot be accurately controlled, it can lead to the death of large numbers of poultry or livestock. Even if they don't die, most of the sulfur is excreted as feces, and the absorption rate of sulfur by the animal body is very low. Summary of the Invention

[0005] In view of this, the present invention proposes an organic sulfur oil for aquaculture and planting and its preparation method, and proposes the application of the organic sulfur oil in aquaculture and planting to solve the problem that it is difficult for animals and plants to absorb sulfur-containing substances, making it difficult for the human body to indirectly supplement its sulfur element by consuming animals and plants.

[0006] On one hand, this invention discloses a method for preparing organic sulfur oil for aquaculture and crop cultivation, comprising:

[0007] S1: Add 1-20 parts by weight of sulfur to 100 parts by weight of vegetable oil and mix to obtain mixture A;

[0008] S2: Heat the mixture A once, keep it at a constant temperature for 1-20 minutes, cool it to room temperature, and add ginger and garlic during the cooling process to obtain mixture B;

[0009] S3: The mixture B is heated a second time and kept at a constant temperature for 1-20 minutes, then cooled to room temperature to obtain the organic sulfur oil;

[0010] The temperature of the first heating is 250-300℃, the temperature of the second heating is 180-220℃, and the total amount of ginger and garlic added is 2-20 parts by weight.

[0011] Furthermore, the organic sulfur oil is filtered before it is obtained in S3.

[0012] Furthermore, the secondary heating is performed 1-5 times.

[0013] Furthermore, the vegetable oil includes one or more of soybean oil, corn oil, and rapeseed oil.

[0014] On the other hand, the present invention also discloses the application of the organic sulfur oil prepared by the above method in a feed additive, wherein the feed additive comprises: 10 parts by weight of the organic sulfur oil, 75-85 parts by weight of zeolite and 8-12 parts by weight of shell powder.

[0015] On the other hand, the present invention also discloses the application of the organic sulfur oil prepared by the above method in farmland irrigation: after diluting the liquid sulfur-containing agent containing the organic sulfur oil, it is irrigated into farmland or sprayed on the surface of crops.

[0016] Furthermore, the liquid sulfur-containing agent comprises:

[0017] 30 parts by weight of the organic sulfur oil, 10-20 parts by weight of the emulsifier and 50-60 parts by weight of water.

[0018] This invention discloses an organic sulfur oil for aquaculture and agriculture, and its preparation method. Compared with the prior art, its advantages are as follows:

[0019] Organic sulfur oil can be manufactured using common vegetable oils, enabling large-scale production. The feed additive, with toxic components removed, is suitable for mixing with poultry, livestock, and aquatic feeds, improving meat quality, enhancing disease resistance, reducing odor from secretions, and increasing user economic benefits. Furthermore, the organic sulfur oil of this invention can be applied in multiple fields, such as by using liquid sulfur-containing agents to irrigate or spray crops, increasing the sulfur amino acid content in plant proteins, producing better-tasting agricultural products, and also treating common plant diseases, especially those caused by mold. Detailed Implementation

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The following will list some embodiments and measurement data of the present invention to illustrate the significant progress of the present invention:

[0022] Preparation of organosulfur oils

[0023] Example 1

[0024] While stirring, mix 100g of sulfur powder into 1000g of soybean oil. After the sulfur powder is added, continue stirring until the sulfur powder is evenly dispersed. Then heat once to 260℃ and hold at that temperature for 10 minutes to obtain a brown viscous liquid intermediate.

[0025] The mixture was cooled to room temperature, during which 100g of sliced ​​garlic and 100g of sliced ​​ginger were added to the mixture and cooled to room temperature. It was then heated a second time to 200°C, cooled to room temperature, and filtered to remove the garlic and ginger, yielding organosulfur oil.

[0026] Example 2

[0027] While stirring, mix 1 gram of sulfur powder into 1000 grams of rapeseed oil. After the sulfur powder is added, continue stirring until the sulfur powder is evenly dispersed. Then heat once to 250°C and hold at that temperature for 1 minute to obtain a brown viscous liquid intermediate.

[0028] The mixture was cooled to room temperature, during which 20 grams of sliced ​​garlic and 20 grams of sliced ​​ginger were added to the mixture and cooled to room temperature. It was then heated a second time to 180°C, cooled to room temperature, and filtered to remove the garlic and ginger, yielding organosulfur oil.

[0029] Example 3

[0030] While stirring, mix 20 grams of sulfur powder into 1000 grams of corn oil. After the sulfur powder is added, continue stirring until the sulfur powder is evenly dispersed. Then heat once to 300°C and hold at that temperature for 20 minutes to obtain a brown viscous liquid intermediate.

[0031] The mixture was cooled to room temperature, during which 200g of sliced ​​garlic and 200g of sliced ​​ginger were added to the mixture and cooled to room temperature. It was then heated a second time to 220°C, cooled to room temperature, and filtered to remove the garlic and ginger, yielding organosulfur oil.

[0032] It should be noted that garlic and ginger need to be pre-treated before adding them. The pre-treatment steps are as follows: remove the outer skin of garlic and ginger, rinse them with clean water until there is no dirt on the surface, and then dry them. After drying, chop the garlic and ginger into small pieces or large chunks for later use. It is preferable to chop them into chunks for easier subsequent filtering.

[0033] The harmful substances in organosulfur oils primarily originate from sulfur powder. Single and double heating removes most of these harmful substances in a gaseous state. Garlic and ginger help to completely remove harmful components from organosulfur oils. Furthermore, the number of reheating cycles is inversely proportional to the amount of harmful substances in the organosulfur oil. However, prolonged and repeated heating reduces the original nutrients in the oil and triggers various chemical reactions that produce harmful substances. For example, high-temperature heating causes fatty acids in the oil to polymerize, leading to growth retardation, liver enlargement, liver damage, and a risk of cancer. Excessive high-temperature heating can also trigger oxidation reactions in edible oils, producing large amounts of volatile substances, including aldehydes, ketones, and polycyclic aromatic hydrocarbons. Acrolein is one of the most dangerous carcinogens in cooking fumes. High-temperature heating causes cis fatty acids in edible oils to isomerize, transforming them into trans fatty acids. Excessive intake of trans fatty acids is associated with obesity, heart disease, diabetes, and chronic diseases such as Alzheimer's disease.

[0034] In addition, the preferred weight percentage of sulfur powder added to vegetable oil is 1-20 parts by weight, more preferably 5-20 parts by weight. When the weight percentage of sulfur powder is less than 1 part by weight, there is no significant difference in efficacy compared to vegetable oil without added sulfur powder. When the weight percentage of sulfur powder is greater than 20 parts by weight, there may be a situation where excessive amounts of sulfur-containing harmful substances cannot be completely removed.

[0035] Detection of organosulfur oils

[0036] The organic sulfur oil prepared in Example 1 was subjected to trace element analysis, and the results are shown in Table 1.

[0037] Table 1

[0038]

[0039] The analysis results in Table 1 show that no harmful components such as arsenic (As), nickel (Ni), chromium (Cr), titanium (Ti), cadmium (Cd), nitrous acid (HNO2), and sulfuric acid (H2SO3) were detected in the organic sulfur oil.

[0040] Preparation of feed additives using organosulfur oils

[0041] Example 4

[0042] Take 20 parts by weight of organic sulfur oil, 160 parts by weight of zeolite and 20 parts by weight of seashell powder obtained in Example 1 and stir them together to obtain the feed additive.

[0043] It should be noted that zeolite is a porous mineral powder that can absorb and expel gas from the intestines, while shell powder is used to provide calcium. The mixing ratio of zeolite and shell powder can be changed according to the actual application scenario. For example, increasing the amount of shell powder can produce a feed additive with high calcium content, or increasing the amount of zeolite can promote digestion and absorption and the expulsion of gas from the intestines.

[0044] In addition, an experiment was conducted on broilers using a feed additive prepared based on organic sulfur oil. The experimental subjects were 50 experimental chickens (broilers) and 50 general chickens, ensuring that the experimental chickens and general chickens came from the same source. The experimental method was as follows: 0.2% of the feed additive prepared in Example 4 was mixed into the chicken feed and fed to the experimental chickens for 32 days. The general chickens were fed the same amount of chicken feed. The experimental chickens and general chickens were raised in two groups, with the same number of feedings, single feeding amount, feeding method, and feeding time. After the feeding time was over, the parameters of the two groups were measured.

[0045] The content of saturated and unsaturated fatty acids in ordinary chickens and experimental chickens is shown in Table 2. The meat quality assessment of ordinary chickens and experimental chickens is shown in Table 3. The sulfur content of ordinary chickens and experimental chickens is shown in Table 4. The sulfur content of eggs from ordinary chickens and experimental chickens is shown in Table 5.

[0046] Table 2

[0047]

[0048]

[0049] Table 3

[0050]

[0051]

[0052] Note: "Relative weight / relative calcium content" is the ratio of the average mass / average calcium content of a normal or experimental chicken to a fixed constant; "juice content" is the content of liquid substances in a normal or experimental chicken excluding water; "weight loss upon heating" is the mass lost when a normal or experimental chicken is heated to the same temperature; "softness" and "aroma" are the taste evaluations conducted by food reviewers, and the evaluation scores are directly proportional to softness and aroma, respectively; "result" is the comparison result of the experimental chicken relative to the normal chicken.

[0053] Table 4

[0054]

[0055] Note: "Index" represents the ratio of a higher content of the same substance in ordinary or experimental chickens to a lower content in experimental or ordinary chickens. The index of the chicken with a lower content is fixed at 100%. For example, the average inorganic sulfur content in experimental chickens is 0.262, while that in ordinary chickens is 0.237. The corresponding indices are: the index of experimental chickens is 0.262 / 0.248 = 110.5%, and that of ordinary chickens is fixed at 100.0%.

[0056] Table 5

[0057] Regular chicken eggs Experimental chicken eggs Sulfur content (%) 0.214 0.251 index(%) 100.00 117.2

[0058] Note: The calculation method for the "index" is the same as in Table 4.

[0059] Table 2-5 shows that the experimental chickens that ingested feed additives had higher levels of cysteine ​​and methionine, which significantly impacted meat quality. Furthermore, it can be inferred that their immunity was enhanced, their lungs were well-developed, and even without antibiotics, the incidence of pneumonia would be significantly reduced, thus saving on feeding costs.

[0060] Preparation of liquid sulfur-containing agents using organic sulfur oil

[0061] Example 5

[0062] Organosulfur oil is an oily liquid containing sulfur. To make it usable in plants, organosulfur oil is mixed with an emulsifier to form a water-soluble liquid sulfur agent.

[0063] The liquid sulfur-containing agent in this embodiment is prepared by mixing 30 parts by weight of organic sulfur oil, 15 parts by weight of emulsifier and 55 parts by weight of water.

[0064] In addition, experiments and results were conducted on crops using liquid sulfur-containing agents prepared from organic sulfur oil;

[0065] Experimental subjects: rice, apples, and cabbage; Experimental method: Rice, apples, and cabbage were planted in experimental and control groups in farmland, and were respectively labeled as experimental group-rice, control group-rice, experimental group-apple, control group-apple, experimental group-cabbage, and control group-cabbage. The experimental and control groups of the same crop were planted in adjacent locations and had the same planting quantity and farmland area. The experimental and control groups were cultivated in the same way. After planting, the experimental groups were irrigated for the first four times with a liquid sulfur-containing agent diluted 400 times with water as described in Example 5.

[0066] It should be noted that the preferred dilution ratio of the liquid sulfur-containing agent for irrigation is 300-500 times. In addition to using the diluted liquid sulfur-containing agent for farmland irrigation, the liquid sulfur-containing agent diluted with water by 300-500 times can also be sprayed on the leaves of crops.

[0067] The yield of rice from the experimental group and the control group was statistically analyzed. The yield of rice from the experimental group was 10% higher than that from the control group. The content of some substances in the rice from the experimental group was also tested, and the results are shown in Table 6.

[0068] Table 6

[0069]

[0070]

[0071] Rice with a sulfur content of 0.07% is called sulfur rice. As shown in Table 6, rice using liquid sulfur-containing agents can have a sulfur content that is up to 4 times higher than other sulfur-treated rice.

[0072] The sulfur content of apples in the experimental group and the control group was measured. The sulfur content of apples in the experimental group was 0.017%, and the sulfur content of apples in the control group was 0.0077%.

[0073] The sulfur content of the experimental group cabbage and the control group cabbage was determined. The sulfur content of the experimental group cabbage was 0.103%, and the sulfur content of the control group cabbage was 0.049%.

[0074] In actual cultivation, it exhibits superior taste and flavor, enabling the production of high-quality agricultural products. Furthermore, it is extremely effective in preventing pests and diseases, reducing pesticide use by half or even less. In particular, sulfur has been proven highly effective against diseases such as verticillium blight, powdery mildew, and root-knot rot.

[0075] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
