Abstract
The present invention relates to a method for making red date peel become crisp in the deep-processing process of red dates, which belongs to the technical field of food processing. Firstly, red dates are fished out after being soaked in 4 to 20% of strong alkali solution for 0.6 to 5 minutes, and then are soaked in cold water; extracted hydrolyzed parts are fished out after being jelled, and are put in 1 to 10% of citric acid to be soaked for 3 to 5 minutes. The soaking temperature of the strong alkali solution is from 80 to 110 DEG C. The strong alkali in the present invention can dissolve cutin and hemicellulose in date peel, and pectin can be hydrolyzed by alkali so as to lose jelly properties to achieve the purpose that the date peel becomes crisp. Compared with the prior art, the present invention has the advantages that 1, when red dates, candied fruits and other products thereof are eaten, the mouth feel is comfortable; 2, because date peel exists and is convenient to process, the product quality is enhanced; 3, the economic benefit is greatly increased.
Description
Technical field
The invention belongs to food processing technology field, specifically is that a kind of red date adds the method for making date peel become crisp in the process deeply.
Background technology
In the prior art, form by pectin, cutin, hemicellulose etc., make it the skin slabbing because of fructus corni.Pectin, cutin etc. are solidified in the skin if be heated.Under the effect of temperature and water, skin and meat can break away from, and the sheet skin can be given a kind of discomfort of people when people edible, are bonded at sometimes in people's the oral cavity people is felt bad.In addition, in the red date without stone processing of producing various better quality, skin should not be removed.One, no skin existence can make jujube meat fall apart in the process, and breakage does not become shaping; Its two, the red date that no skin exists can cause a kind of illusion to the people, and the people is felt confused.But to also not having a kind of method can solve this difficult problem so far.
Summary of the invention
The invention solves problems of the prior art, a kind of neither peeling is provided, can make fructus corni shortcake, mouthfeel is good, outward appearance is beautiful method of making date peel become crisp again.
The present invention adopts following method to realize, a kind of method of making date peel become crisp, a, red date is immersed in the strong base solution of 4-20%, 0.6-5 pull out after minute, b, in cold water, soak again, pull out behind the partial gel that leaching is hydrolyzed, c, be placed on to soak after 3-5 minute in the citric acid solution of 1-10% and get final product, the soaking temperature of strong base solution is 80-110 ℃.Highly basic among the present invention can be with the cutin in the fructus corni, hemicellulose dissolving, and pectin can be separated by diminishing and lose gelling, has reached fructus corni and has become crisp purpose.
A kind of method of making date peel become crisp of the present invention, a, red date is immersed in the strong base solution of 6-15% and pulls out after 1-3 minute, b, in cold water, soak again, pull out after leaching the partial gel that is hydrolyzed, c, be placed on to soak after 3-5 minute in the citric acid solution of 1-10% and get final product.
The soaking temperature of strong base solution of the present invention is 90-104 ℃.
Highly basic of the present invention is potassium hydroxide or NaOH or calcium hydroxide.
The present invention has following effect and advantage, and 1, when edible during product such as red date and preserved fruit thereof, mouthfeel is comfortable; 2, because fructus corni exists, be convenient to processing, thereby improved the quality of product; 3, economic benefit also increases substantially.
The specific embodiment
Embodiment 1,
At first, prepare strong dehydrogenation (-nization) sodium hydroxide solution, concentration is 10%, and citric acid solution, concentration is 2%, then strong dehydrogenation (-nization) sodium hydroxide solution is heated to 100 ℃, then red date is put into the sodium hydroxide solution after the heating, soak and pull out after 1.5 minutes, be immersed in the water and pull out after 3 minutes, pulled out in 3 minutes in the bubble citric acid solution of going into to prepare and to make fructus corni become crisp.
Claims (3)
1, a kind of method of making date peel become crisp, a, red date is immersed in the strong base solution of 4-20% and pulls out after 0.6-5 minute, b, in cold water, soak again, pull out behind the partial gel that leaching is hydrolyzed, c, be placed in the citric acid solution of 1-10% and soaked 3-5 minute, the soaking temperature of strong base solution is 80-110 ℃.
2, method of making date peel become crisp according to claim 1, it is characterized in that: a, red date is immersed in the strong base solution of 6-15% and pulls out after 1-3 minute, b, in cold water, soak again, pull out behind the partial gel that leaching is hydrolyzed, c, be placed in the citric acid solution of 1-10% and soaked 3-5 minute, the soaking temperature of strong base solution is 90-104 ℃.
3, method of making date peel become crisp according to claim 1 is characterized in that highly basic is potassium hydroxide or NaOH or calcium hydroxide.
