Description

Fried peanuts and processing method thereof
Technical Field
The invention relates to fried peanuts and a processing method thereof, belonging to the technical field of food processing and preservation.
Background
The fried peanuts are the traditional characteristic peanut food in China, are golden in color and crisp in taste, and are deeply popular with consumers at home and abroad. However, the fat content of the fried peanuts is high, and the fried peanuts are easily influenced by external factors such as air, illumination, temperature, metal ions and the like, so that fat oxidation rancidity is caused to generate lipid peroxide poisons such as aldehydes, ketones, lactones and the like, rancid taste problems such as rancidity occur, and further the flavor quality and the shelf life of the fried peanuts are influenced.
In the prior art, the research on fried peanuts mainly relates to the aspects of production technology and formula, processing equipment, cooling equipment and the like. CN101061874B the fried peanuts with a normal temperature shelf life of more than 8 months are prepared by blanching, peeling, pickling, frying and vacuum packaging technologies. In the preparation process, the peanuts are pickled by the tertiary butyl hydroquinone solution, and the tertiary butyl hydroquinone with the total oil amount of 0.2 per mill is added into the frying oil, so that the antioxidant effect of the fried peanuts is improved, but the pickling time is too long and reaches 105 minutes, and no supplementary description is provided for the frying loss of the tertiary butyl hydroquinone in the frying process. In CN102524851B, a fried peanut with a low peroxide value is prepared by a nitrogen-filled frying technology, a water-oil mixed frying technology, an edible film coating technology and a low-temperature freeze drying technology, the frying temperature is effectively reduced, the shelf life is prolonged to 360 days, but the technology has large equipment investment and higher processing cost. CN107149118A is prepared by cooking peanut 3-5 min, adding 50-70 deg.C edible oil, heating, frying, and mixing with edible salt and food additive. However, peanuts are heated and fried with edible oil, easily penetrated with excess oil, and no description is made as to how to package them.
Disclosure of Invention
The invention aims to provide a processing method of high-quality fried peanuts with long shelf life, which is simple to operate and beneficial to wide popularization, and can ensure the taste of the fried peanuts and prolong the shelf life of the fried peanuts. Solves the problems of easy oxidation and short shelf life of the existing fried peanut product.
In order to solve the technical problems, the invention provides a method for processing high-quality fried peanuts with long shelf life.
A processing method of fried peanuts comprises the following steps:
(1) peeling semen Arachidis Hypogaeae, oven drying, and soaking in 80-85 deg.C hot water for 4-6 min;
(2) taking out the peanuts obtained in the step (1), draining, adding the stirring materials, uniformly stirring, and pickling for 70-75 min;
(3) heating the edible compound oil added with the tert-butyl hydroquinone to 175-180 ℃, frying the peanuts for 6-6.5min, taking out and draining;
(4) and (4) cooling the fried peanuts obtained in the step (3) to below 35 ℃, and packaging and sealing by adopting opaque nitrogen-filled package to obtain the fried peanuts.
In one embodiment of the present invention, in the step (1), the drying temperature is 120-.
In one embodiment of the invention, in the step (2), the stirring material is obtained by uniformly mixing white granulated sugar and edible salt.
In one embodiment of the invention, the mass ratio of the white granulated sugar to the edible salt is 0.8-1: 1.
In one embodiment of the present invention, in step (3), the edible compound oil is prepared by the following method: mixing rapeseed oil and palm oil in a volume ratio of 2-3: 2, mixing, adding tert-butyl hydroquinone, and uniformly stirring to obtain the edible compound oil.
In one embodiment of the invention, the tertiary butyl hydroquinone is food grade.
In one embodiment of the invention, the mass fraction of the tert-butyl hydroquinone in the edible compound oil is 0.1-0.15%.
In one embodiment of the invention, in the use process of the edible compound oil, the tert-butylhydroquinone is supplemented into the edible compound oil for 2 hours each time the edible compound oil is fried, so that the mass fraction of the tert-butylhydroquinone in the edible compound oil is 0.1-0.15%.
In one embodiment of the present invention, in step (4), the light-tight nitrogen-filled package is sealed by filling nitrogen gas into a light-proof aluminum foil bag and then sealing.
The fried peanuts are prepared by the processing method.
Compared with the prior art, the technical scheme of the invention has the following advantages:
1. according to the invention, the peeled peanuts are soaked in hot water, so that the soaking time is shortened, and the peanuts are convenient to be pickled and tasty; the pickling and stirring materials adopt white granulated sugar and edible salt, other additives are not added, the body metabolism burden is reduced, and the health consumption concept of modern people is met.
2. The fat-soluble tert-butyl hydroquinone is directly added into the edible oil, fully stirred and dissolved for later use, and compared with the method of directly adding the fat-soluble tert-butyl hydroquinone into the stirring material, the concentration of the antioxidant in the fried peanuts is reduced, and the acid value of the peanuts is favorably reduced; according to the invention, tert-butyl hydroquinone is periodically added into the frying oil in the frying process, so that the loss in the frying process is compensated, the concentration of the tert-butyl hydroquinone is kept at 0.1-0.15%, the quality of the frying oil is kept, and the service life is prolonged.
The compound oil of the rapeseed oil and the palm oil is used as the frying oil, has stronger antioxidant stability than the single rapeseed oil and the single palm oil, and is beneficial to improving the antioxidant stability of the product. In addition, the oil temperature is heated to 175-180 ℃ to fry the peanuts, so that the oil infiltration in the frying process of the peanuts is reduced.
3. The invention adopts the light-tight nitrogen-filled package to seal the fried peanuts, and can further prevent the oxidation rancidity of grease caused by the transmission of ultraviolet rays, thereby prolonging the shelf life and leading the storage at normal temperature to be 12 months.
4. The preparation method disclosed by the invention is simple in process and convenient to operate, not only can shorten the whole product preparation period, but also can ensure the quality and taste of the fried peanuts; is suitable for large-scale industrial production, and has remarkable social benefit and economic benefit.
