Description
Technical field
The present invention relates to tea seed field, is a kind of working method of giving off a strong fragrance nutritional oil tea-seed oil.
Background technology
The working method of existing giving off a strong fragrance nutrition tea seed, the squeezing process of employing and the squeezing process of large oil plant are substantially similar, be by tea seed dry, softening, shelling, broken, roll embryo, enter cooking pot and steam and fry, enter screw oil expeller and carry out hot moulding.The crude oil of pressed oil is heated to 70-80 DEG C after filtering, and adds the hot water of the heavy 3-5% of oil to carry out hydration degum, and about 20min of time, is then heated to 85-95 DEG C of vacuum-drying, is after the assay was approved finished product after filtration.Adopt existing method, due to can not be very strict to the control of raw material, thereby the quality of oil product and security can not be effectively guaranteed, and the quality of oil product is difficult to reach GB11765-2003 one-level squeezing processed oil camellia seed oil quality index, substantially can only reach squeezing secondary standard, quality is on the low side; Be hydration degum due to what adopt, inevitably can cause the part emulsification of grease, reduced oil yield; In order to remove the colloid in oil, adopt the method for the rear rehydration of heating, unavoidably can cause the volatilization of flavour ingredient; In order to remove moisture, adopt vacuum drying method, make the most of loss of giving off a strong fragrance composition.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, a kind of working method of giving off a strong fragrance nutritional oil tea-seed oil is provided, after specifically the tea seed of high-quality being fried, squeeze, crude oil after squeezing is come unstuck, more a kind of method of carrying out press filtration with the squeeze cake of drying after pulverizing, make the giving off a strong fragrance oil after processing, not only can directly eat, and improve the nutritive ingredient of oil product.
The present invention solves the technical scheme that its technical problem adopts: the working method of this giving off a strong fragrance nutritional oil tea-seed oil, the method comprises the steps:
(1) moisture is less than to 12%, impurity is less than 0.5%, and without going mouldy, anacidity peculiar smell, after the cleansing oil tea seed of free from insect pests is peeled off and dried, dries moisture to below 8% with dryer;
(2) tea seed of drying, enters Rotating oven and fries seed, fries seed temperature 130-140 DEG C, time 30-45min;
(3) tea seed having fried, enters while hot oil press zhai and extracts oil, and the tea-seed pancake oil-containing after oil expression is no more than 6%;
(4) tea-seed pancake that accounts for the rear tea-seed pancake total amount 5% of squeezing is dried to moisture and be no more than 3%, then wear into powder with the pulverizer of aperture 1.5mm;
(5) pressed oil, with after Filter Press, under normal temperature, adds according to the 0.08%-0.12% of pressed oil quality the citric acid solution that mass percent is 52%, under the condition of continuously stirring, and reaction 90min;
(6) pressed oil after acid-respons, under normal temperature, adding mass percent concentration according to 0.5% of pressed oil quality is 5% NaCl solution, continuously stirring reaction 30min, after leaving standstill emits upper edible vegetable oil;
(7) by the tea-seed pancake that grinds is also dried, join in upper edible vegetable oil according to the 1-3% of pressed oil quality, press filtration under continuously stirring, is finished product after the assay was approved.
The squeezing of tea seed:
Moisture is less than to 12%, and impurity is less than 0.5%, and without going mouldy, anacidity peculiar smell, after the cleansing oil tea seed of free from insect pests is peeled off and dried, dries moisture to below 8% with dryer.The tea seed of drying, enters Rotating oven and fries seed, fries seed temperature 130-140 DEG C, time 30-45min.The tea seed having fried, enters while hot oil press zhai and extracts oil, and squeezing for the first time will go out cake thickness and adjust to 3mm left and right, squeeze out for the second time, for the third time cake thickness 1.5mm left and right, and the tea-seed pancake oil-containing after oil expression is no more than 6%;
Giving off a strong fragrance hair oil degumming:
The tea-seed pancake that accounts for the rear tea-seed pancake total amount of squeezing 5% left and right is dried to moisture and be no more than 3%, then wear into powder with the pulverizer of aperture 1.5mm.Pressed oil, with after Filter Press, under normal temperature, adds 52% citric acid solution according to the 0.08%-0.12% of pressed oil quality, under the condition of continuously stirring, and reaction 90min.Pressed oil after acid-respons, under normal temperature, adding concentration according to 0.5% of pressed oil quality is 5% NaCl solution, continuously stirring reaction 30min, after leaving standstill emits upper edible vegetable oil.By drying ground tea-seed pancake, join in upper edible vegetable oil according to the 1-3% of pressed oil quality, press filtration under continuously stirring, is finished product after the assay was approved.
Principle of the present invention is: adopt the tea seed of high-quality to dry, fry after seed, with screw oil expeller oil expression, the crude oil of pressed oil adopts High Content Citric Acid, 5%NaCl solution to come unstuck, and finally adds the powder tea-seed pancake press filtration of oven dry.Due to process adopt be appropriateness fry seed, completely squeezing, the reservation of nutritive ingredient and the generation of objectionable impurities will be lacked compared with common process; The employing High Content Citric Acid that comes unstuck, without alkali refining, has retained nutritive ingredient to greatest extent; Adopt the powder tea-seed pancake of drying to make filter cake, not only played and had the effect of the flavouring of oil product, and effectively removed unnecessary moisture.
Giving off a strong fragrance complete processing of the present invention, compares with the giving off a strong fragrance technique of prior art, and the nutritive ingredient of camellia seed oil has obtained more effective reservation, both can directly eat, and the fragrance of oil product is strong far beyond existing technique without heating.
The present invention compared with prior art, has adopted complete appropriateness to fry the method for seed, entirely fries seed squeezing, and crude oil adopts High Content Citric Acid, 5%NaCl solution to come unstuck, and by squeeze cake dry pulverize after for last filtration and remove a small amount of moisture.Adopt existing technology, the index of giving off a strong fragrance oil meets GB11765-2003 one-level squeezing processed oil camellia seed oil quality index completely, and aromatic flavour; Compared with existing giving off a strong fragrance oil tea oil preparation technique, adopt after the present invention, not only make the beneficiating ingredient of camellia seed oil better be retained, and also best in quality, fragrance is denseer.Compared with existing conventional degumming technology, adopt High Content Citric Acid, 5%NaCl solution degumming technology, dry the press filtration of powder tea-seed pancake, not only effectively reduced the loss of camellia seed oil nutritive ingredient, also effectively retained, improved the flavour ingredient of giving off a strong fragrance nutrition tea seed.
