Problems solved by technology

However, camellia seed kernels belong to arbor tree kernels. After processing, camellia seed kernels are easy to oxidize and correspondingly increase the acid value, making the color of camellia seed kernels black and lower in quality, resulting in an increase in the acid value and lower quality of the extracted camellia oil.
It has caused great constraints to the increase of high value-added exports of camellia oleifera seeds
Even if the packaging is improved and conventional preservatives are added for preservation, the preservation effect is still not ideal, and the problem of chemical additives exceeding the standard is likely to occur
Chinese Patent Publication No.: CN1197111A, Publication Date: October 28, 1998, Invention Name: "Oil Composite Antioxidant Preservative", which proposes a composite antioxidative antistaling agent mainly composed of TBHQ, citric acid, and isopropyl citric acid agent, has good thermal stability and safety, but this technical solution is mainly added to liquid oil, and cannot be applied to the anti-oxidation preservation of dried fruit foods such as oily nuts

Embodiment 1

[0034] Take 500 kilograms of fresh peanuts, fry the moisture on the surface; take 4 grams of tert-butyl hydroquinone, 2.9 grams of sodium dihydrogen phosphate, 2.6 grams of citric acid, and 0.5 grams of activated carbon with a fineness of 100 mesh, and prepare 10 grams of Food deoxidation preservative, add 100 grams of water and mix it into an aqueous solution, then add the aqueous solution of food deoxidation preservative to the fried fresh peanuts, mix well, then fry the moisture on the surface of the peanuts, take it out of the pan and let it cool, put it in Store below 30°C, and after half a year, check that the color of the peanuts is as bright as before, and no moldy spots or rotten peanuts have been detected.

Embodiment 2

[0036] Take 500 kg of fresh sunflower seeds, fry them in a wok until they are half mature; take 3.5 grams of tert-butyl hydroquinone, 2.8 grams of sodium dihydrogen phosphate, 2.2 grams of citric acid, and 2.5 grams of activated carbon with a fineness of 150 meshes, and prepare 10 grams of Food deoxidation preservative, add 150 grams of water and mix it into an aqueous solution, then add the food deoxidation preservative aqueous solution to the fried sunflower seeds, mix evenly, then fry the sunflower seeds, take them out of the pan and let them cool, then store them below 30°C. Half a year later, the color of the sunflower seeds was checked as before, the shells were crisp, and the kernels were crispy and delicious, with a delicate fragrance and no peculiar smell, and no moldy or deteriorated sunflower seeds were detected.

Embodiment 3

[0038] Take 20,000 kg of fresh camellia seed kernels, send them into the drying room, the top of the drying room is a hot air outlet, cover the surface of the camellia seed kernels with cotton cloth or chemical fiber cloth, start the hot air blower, and heat it at 50°C Fresh camellia seed kernels, so that the water content of fresh camellia seed kernels is reduced from about 20% to 15% to 13%; tert-butyl hydroquinone is 36%, sodium dihydrogen phosphate is 23%, citric acid is 18%, fineness 150-mesh activated carbon 23%, prepared into 1000 grams of food deoxidation preservative, and mixed with 4000 grams of water to form an aqueous solution; a drip hose is arranged on the air inlet of the hot air blower, so that the drip outlet of the drip hose is located in the pipeline of the air inlet , the other end of the dripping hose is connected to the bottom of the liquid container of the food deoxidizing preservative, and the dissolved food deoxidizing preservative liquid is dripped fro...

Abstract

The invention discloses a food deoxidation preservative and its use method, and a method for deoxidation and preservation of camellia seed kernels, belonging to the field of food additives. The composition and weight percent of each raw material are: 30%-40% of tertiary butyl hydroquinone, 20%-30% of sodium dihydrogen phosphate powder, 15%-30% of citric acid, and 5%-35% of activated carbon. The method of use is as follows: first add water to the food deoxidizing preservative and mix it into an aqueous solution; then add the aqueous solution of the food deoxidizing preservative to the dried processed food, mix evenly, and then dry the processed food. The invention has the advantages of convenient preparation, small dosage, no toxic and side effects, safe use, simple and convenient use method, good fresh-keeping effect, long fresh-keeping period and longer time of deoxygenation and fresh-keeping effect. It is especially suitable for deoxygenation preservation of oily nut kernels and dried fruits such as peanut kernels, camellia seed kernels, pine nuts, etc. after drying.

Description

technical field [0001] The invention relates to a food additive and a fresh-keeping method, in particular to a food deoxidizing and fresh-keeping agent and a using method thereof, and a deoxidizing and fresh-keeping method of camellia oleifera seeds. It belongs to the field of food additives. Background technique [0002] Camellia oil extracted from camellia oleifera seeds is rich in 17 kinds of amino acids necessary for the human body and trace elements such as zinc and selenium, and its quality exceeds that of olive oil, the first oil in the West. my country's camellia seeds are widely exported to Japan, Europe and the United States and other countries. Camellia oleifera seeds are light in proportion and relatively low in oil content, so the cost of packing and exporting is high, and because camellia oleifera seeds are wrapped in tea shells, the quality is difficult to distinguish, so the export volume is small. Camellia oleifera seed kernels obtained after shelling came...
