Abstract
The invention discloses a modification treating method for sweet potato dregs, an application thereof and a high-fiber sweet potato product. The method takes sweet potato dregs as a raw material, and obtains modification treated sweet potato dreg powder after drying, heat-moisture treating and smashing the sweet potato dregs. The sweet potato dreg powder has better addition property, and can be added into flour largely for preparing products such as high-fiber sweet potato noodles or high-fiber sweet potato biscuits; the high-fiber sweet potato noodles or the high-fiber sweet potato biscuits prepared through treatment have high dietary fiber content, and effectively retain nutrients in the sweet potato dregs such as starch and protein, thereby providing a customer with a receptive product capable of effectively supplementing the dietary fiber. The invention provides an effective production method for development and utilization of the sweet potato dregs and a product; the preparation technology is simple; the cost is low; the utilization of the raw material, namely the sweet potato dregs, is realized to the maximum extent; resource waste and environment pollution are reduced.
Description
Technical field
The present invention relates to a kind of modification processing method, application and high fiber Ipomoea batatas product of sweet potato waste, belong to food processing technology field.
Background technology
Ipomoea batatas has another name called sweet potato, pachyrhizus, sweet potato etc., is rich in protein, starch, pectin, cellulose, amino acid, vitamin and several mineral materials, has anticancer, cardioprotection, prevention pulmonary emphysema and the effects such as diabetes, fat-reducing, and the reputation of " life prolonging food " is arranged.Sweet potato waste is that Ipomoea batatas produces the byproduct in the starch process, and is nutritious, there are some researches show, moisture 90.96% in the fresh sweet potatoes slag, starch 3-5%, cellulose 1.51%, ash content 0.11-0.28%, protein 0.26-0.95%.(Zhou Shuai, Wu Jianguo, Zhang Xiaoyu, Wang Hongxun. the academic Conference Papers collection of the development and use .2005 Chinese industrial microorganism of sweet potato waste industrial microorganism progress, 588-590).
Along with the development of starch industry and food industry, produced a large amount of sweet potato wastes in starch from sweet potato and the three powder product process, its majority is all worked as waste material and is abandoned, and has caused environmental pollution and wastage of material.In recent years, how it is effectively developed, more and more receive people's concern, but sweet potato waste is mainly used in Fodder making and fertilizer at present.Be the patent of CN102934736A, CN101643372A and the CN103044101A preparation method that reported respectively sweet potato skin or sweet potato powder residue fermented feed, utilize sweet potato waste to prepare the method for organic fertilizer and chicken manure fertilizer such as publication number.But except containing a small amount of starch, major part is cellulose and hemicellulose in the sweet potato waste, and protein content is very low, utilizes the feed of its making to be difficult for being absorbed by animal, always as the low price feed; And the fertilizer that utilizes sweet potato waste to prepare fails to take full advantage of the dietary fiber that it is rich in, and causes the wasting of resources.Along with the development of science and technology, in recent years the profound utilization of sweet potato waste also begun to have had report.Be the preparation method that the patent of CN1623422A and CN101849657A has been reported respectively sweet potato diet microcrystal cellulose and sweet potato dietary fiber such as publication number, but these methods all need be got rid of starch contained in the sweet potato waste with the preparation sweet potato dietary fiber through loaded down with trivial details technique, it is added in the food as additive, and cost also can significantly increase.Directly add sweet potato waste and prepare food product, for example directly add sweet potato waste and prepare noodles to flour, its contained a large amount of fiber substances can have influence on the fundamental characteristics of noodles, when addition reaches certain value even can not form dough, can't prepare noodles.Therefore, in order to increase the addition of sweet potato waste in food product, need to carry out modification to sweet potato waste.Zhang Zhaoqin etc. have prepared the sweet potato waste dietary fiber and have studied its impact (Zhang Zhaoqin etc. on the bread quality by sweet potato waste is processed, the preparation of sweet potato waste dietary fiber and on the impact of bread quality, Jiangxi food industry, the 1st phase in 2009,32-33), but the method also mainly is to get rid of starch in the sweet potato waste to improve the content of dietary fiber, complex treatment process on the one hand, and cost is higher; Also wasted on the other hand starch component contained in the sweet potato waste, and the sweet potato dietary fiber that obtains after the wherethrough reason has also only substituted 5% flour.This is that its retention ability and expansive force are very poor because cellulosic structure is tight, water insoluble, so dietary fiber has certain interpolation limit, otherwise can affect the fundamental characteristics of food, even can't be processed into corresponding food at all.At present, with being added directly to the production method of producing high fiber sweet potato waste product in the flour after the sweet potato waste modification report has been arranged also.Such as (Ni Wenxia such as Ni Wenxia, Wang Hongxun, Wang Shangyu, in poplar. the research that high-quality sweet potato waste is used in noodles. food science and technology, the 2nd phase in 2012) pass through to adopt the method for extrusion and cellulase degradation to the sweet potato waste modification, and be added into and produce high fiber sweet potato waste noodles in the flour, but the maximum addition of the method sweet potato waste only is 12%.
Summary of the invention
The object of the present invention is to provide a kind of modification processing method, application and high fiber Ipomoea batatas product of sweet potato waste, the method is to extract sweet potato waste behind the starch as raw material, through can significantly improving its addition in the preparation food product after the modification, thereby can environmental contamination reduction, realize effective utilization of sweet potato waste raw material.
For achieving the above object, the technical solution used in the present invention is as follows:
1) drying: sweet potato waste is cleaned removal of impurities, the main component weight percent content of described fresh sweet potatoes slag is: starch 3.2-7.3%, crude fibre 1.8-2.6%, protein 0.15-0.17%, moisture 90-95%, being dried to moisture under 70-90 ℃ temperature conditions is 25-35%, records other each constituent content to be: starch 43-53%, crude fibre 15-30%, protein 1-2.5%;
2) humid heat treatment: will place closed container to seal through the dried sweet potato waste of step 1), humid heat treatment 8-12h under 100-110 ℃ temperature conditions;
3) pulverize: will be through step 2) in sweet potato waste dry 2-4h under 70-90 ℃ of temperature conditions after the humid heat treatment, pulverizing is by the 80-100 mesh sieve, the sweet potato waste powder of modification, record each constituent content and be: starch 58-65%, crude fibre 20-36%, moisture 1-3%, protein 1.8-3.5%;
4) high fiber sweet potato waste product preparation: the sweet potato waste powder that step 3) is obtained is added in the flour by a certain percentage, mix by different production methods and make high fiber sweet potato waste product, described high fiber sweet potato waste product comprises high fiber sweet potato noodle and high fiber sweet potato biscuit, and the preparation method is as follows respectively:
A. high fiber sweet potato noodle preparation: the sweet potato waste powder that step 3) is obtained is added in the flour, and adding proportion is sweet potato waste powder 35-50 weight portion, flour 50-65 weight portion, salt 0.2-0.4 weight portion mixes, and adds the 30-40 weight parts water, with face 5-10min, rub into the dough with toughness, moisturizing slaking 20-30min, compressing tablet, slitting, preferably, the slitting width is 2-3mm, drying namely gets high fiber sweet potato noodle, and its dietary fiber content reaches 10-15%;
