Description

Raw candy preserved apricot and production Technology thereof
Invention field
The present invention relates to produce the technology of raw candy preserved apricot and the raw candy preserved apricot field of acquisition thereof.
Background technology
Normally a kind of preserved fruit of making of apricot of preserved apricot.At present openly process the common technological process of production of preserved apricot and have two kinds.
1: select materials by cleaning, stoning, protect look, ooze sugar, baking, shaping, packing obtain the preserved apricot goods (good to eat net. preserved apricot, [EB/OL] .[2007-06-28] .http: //keko.eat.51ttyy.com/material/material_134550534000_745.h tml).
2: by select raw material, cleaning, cutting, stoning, sulphuring, candy, sugaring, more candy, again sugaring, integer, baking, packing obtain the preserved apricot goods (the food partner nets .[EB/OL] .[2007-07-06] .http: //www.foodmate.net/tech/jiagong1/2487.html).
The common means of protecting look are exactly sulphuring or soak sulphur--aqueous solution of sodium bisulfite soak (cuisines net everyday. dry fruit is made the preserved apricot of complete works, [EB/OL] .[2007-06-020] .http: //www.ttmeishi.com/CaiPu/335d3d6f80fleld7.htm), and the sulfur content index is one of important test item of preserved fruit based food quality safety; Ooze sugar and then be and processed one of technology that preserved apricot must carry out in the past (sugar content is to press to suppress the bacterial classification survival in order to keep high Premeabilisation of cells greater than 64%, the long preservation that helps product), some enterprise is in order to adjust mouthfeel and product appearance color and luster, also added additives such as sweetener, anticorrisive agent and pigment (good to eat net. preserved apricot, [EB/OL] .[2007-06-28] .http: //keko.eat.51ttyy.com/material/material_1134550534000_745. html).
Hence one can see that, and at present the processing technology high purpose of preserved apricot sugar content of producing is in order to increase local flavor on the one hand, and main purpose then is to keep hyperosmosis, suppresses microbial survival; Sulphuring or the purpose of soaking sulphur are to suppress activation of microorganism on the one hand, and main purpose is to protect look, increase the product appearance color and luster; Add the purpose that additive then has simultaneously to be increased local flavor, inhibition activation of microorganism, increase the product appearance color and luster.
Microwave is meant the frequency electromagnetic waves of wave-length coverage between 1mm-1m (frequency is 300 MHz~300 GHz).Microwave drying originates from the forties in 20th century, and to late 1960s, microwave heat energy has been applied on the industrial projects such as heating, drying, desinsection, medical treatment.Advantages such as microwave drying is fast with rate of drying, selectivity heating, even heating.As a kind of new energy, microwave (the Ana Andr é s that in food industry, is widely used, Cristina Bilbao, Pedro Fito.Drying kinetics of apples cylinders under combined hotair-microwave dehydration[J] .Journal of Food Engineering, 2004,63:71~78).In Japan, annual about 400,000 tons of microwave food, 1,400 hundred million yen of the output values.China's microwave food successfully is applied to microwave energy many fields such as baked foods, dry fruit bake, beef drying, fruits and vegetables ' dehydration, fast food face drying, drink sterilization, and obtain remarkable break-throughs (Zhang Qingfeng, height is willing to army, Li Jianguang. the application [J] of microwave technology in fruit processing, the Henan agricultural sciences, 2007,3:96~98).
As far back as the forties in 20th century, vacuum-packed technique is born in the laboratory, and along with entering of composites such as polyester, polyethylene before and after nineteen fifty, this technology is just grown up rapidly.Vacuum packaging is that article are packed into behind the airtight container, vacuumizes before container closure, makes a kind of packing technique that does not have air in the container after the sealing substantially.
Adopting vacuum-packed food is not the perfect vacuum, and the vacuum in the container is usually at 600-1333Pa.Therefore, again vacuum packaging is called decompression packing or exhaust packing.
Since the preserved apricot that adopts prior art processing through sulphuring, candy, add additive etc. and suppress the microorganism measure, therefore, do not adopt the vacuum-packed technique packing.
The apricot that Xinjiang produces best in quality: apricot sugar and vitamin content height, raciness.Measurement result shows, soluble solid is higher than 16% account for more than 65%, is up to 29%, belongs to the extremely many scopes of content, on average exceeds about 5~8% than other zone varietys.Most kind acid contents are between 0.5~1.0%.Vc content is up to 23mg/100g at 9.1~15.0mg/100g, than the high 3-5mg/100g of other zone varietys.Many kinds all belong to the Li Guang subspecies, and peel smooth is not had fine hair, freestone, sweet benevolence (Liao Mingkang, Guo Lixia, Zhang Ping, Che Fengbin, Liao Kang. Xinjiang apricot platymiscium peroxidase catechol-oxydase Isozyme Analysis [J]. northwest agricultural journal, 1994,3 (2): 81-86; Zhang Jiayan etc. write. Chinese fruit tree will. and apricot volume [M]. Beijing: China Forest publishing house, 2003; Magnify the sea. Xinjiang apricot production status and development countermeasure [J], Xinjiang Agricultural Univ's journal, 2005,28 (monographs): 36-38).
Current, the method for airing dried apricot is demanded urgently improving.The not anti-storage of apricot fruit transportation, the apricot fruit mainly is processed into the apricot thickened pulp or is processed into dried apricot except that being used on a small quantity to eat raw.Owing to the influence of multiple reasons such as the market demand, except a part was used to process apricot thickened pulp usefulness, other a large amount of bright apricots will be processed as dried apricot.But at present the method for peasant household's airing dried apricot is very backward, and peasant household is layered on bright apricot usually directly shines into dried apricot on the straw mat, and the fruit face often falls to having the fine sand dust, and dried apricot also can variable color when meeting rainy weather, makes the exterior of commodity of dried apricot poor; During airing in the open, the contact of fly worm is without cease, grows worm's ovum arbitrarily.When the degree of drying deficiency, or deposit not at that time, infested phenomenon is arranged, cause dried apricot to lose commodity value; Almond is arranged in the dried apricot, abandon and then waste resource, produce to pollute, eat almond and may injure tooth and sting out almond, the almond shell also can produce pollution, and the high-grade dried apricot the inside that meets safety and health request on the international market does not then have almond.(Xinjiang Uygur Autonomous Regions statistics bureau. Xinjiang statistical yearbook [M]. Beijing: China Statistics Press; Magnify the sea. Luntai County, Xinjiang apricot industrialization management research: [master thesis]. Beijing: China Agricultural University, 2007) thereby how to use the processing technology that modern science and technology is improved dried apricot, produce the new product that meets food security standard, become the key that can current apricot industry healthy and sustainable development.
Along with the raising of modern life quality, people more and more pursue the diet of safety and Health, and notions such as low sugar low-energy food, natural green food are rooted in the hearts of the people.And it is very necessary to solving current apricot industry development to develop new apricot product after-processing technology and product.Have not yet to see the color of utilizing microwave fixed processing apricot converted products, reach drying and sterilization effect simultaneously, and cooperate to adopt vacuum-packed technique, make the report of raw candy preserved apricot, with and the addressing of manufacture craft technology.
