The additive mainly comprises 20 to 35% of bamboo leaf flavones and 12 to 25% of bamboo leaf polysaccharide. The preparation method comprises the following steps of 1, extracting bamboo leaves preliminarily, 2, extracting circularly residues obtained from the step 1 multiple times, and 3, carrying out a spray drying process on extract obtained by the multiple extraction processes in the step 2 to obtain a bamboo leaf extract additive. The bamboo leaf extract additive has the functions of sterilization, bacteriostasis, flesh tenderization and color protection.
Description
Technical field
The present invention relates to a kind of bamboo extractive additive and preparation method thereof, be mainly used in the preliminary treatment of meat products, belong to natural plants additive technology field.
Background technology
China have the title of " bamboo kingdom ", and the leaf of bamboo has long edible and medicinal history in China, and is all on the books as " book on Chinese herbal medicine is looked for the truth ", " herbal classic is met former ", " medicine justice ", " through saying " etc. in the successive dynasties document.
In today of uphold nature, the purposes of natural function material is paid close attention to by people.Bamboo is a grass family perennial evergreen plant, is one of plant of having use value most of the world today.Yet with regard to the integral body utilization of bamboo, the exploitation of the leaf of bamboo is obviously lagged behind.Nowadays, bamboo extractive is just causing the attention of food nutrition brainstrust as a kind of new flavonoids health care nutrient.The medical care effect of the leaf of bamboo is familiar with by China people already.The leaf of bamboo has long edible and medicinal history in China, records the slow spleen of the cool heart, clearly effect such as quench the thirst according to medical book, and this explanation leaf of bamboo is the traditional simply heat-clearing and detoxifying drug of the traditional Chinese medical science.1998, (light) leaf of bamboo was listed in " medicine, the dual-purpose natural plants list of food " again by Ministry of Public Health's approval.Show after deliberation, contain a large amount of flavone compounds and bioactive polysaccharide and other active ingredient in the leaf of bamboo, raising along with people's living standard, the safety and Health consumption consciousness constantly strengthens, the instructions for use of food additives is strict more, and bamboo extractive more and more is subjected to consumers in general's welcome as a kind of natural additive for foodstuff.
Summary of the invention
The present invention is raw material with the leaf of bamboo, through processing, the extraction of science, makes a kind of bamboo extractive additive of natural green.Extract effective ingredients such as effective ingredient flavones and biological polyoses from the leaf of bamboo, this product is used for the preliminary treatment of cold fresh meat, and the effect that can play antibiotic, antibacterial, meat tenderization and protect look significantly improves commodity.
Technical scheme of the present invention to achieve these goals is to adopt following means to realize:
Bamboo extractive additive Main Ingredients and Appearance is bamboo-leaves flavones 20%-35%, leaf of bamboo polysaccharide 12%-25%.
The extracting method of bamboo extractive additive is:
A kind of bamboo extractive additive, by the leaf of bamboo through twice recirculated water carry with an alcohol extracting after by concentrating, spray-dried again handle extract dry powder.
The raw material leaf of bamboo is cleaned up;
Raw material is packed in the multi-function extractor, through 5 times of water gagings, boil 0.5h, steam pressure is that 1Mpa handles, and filters, and obtains first filtrate and filter residue;
Filter residue boiled 0.5 hour once more through 5 times of water gagings, and steam pressure is that 1Mpa handles, and filters, and obtains second filtrate and filter residue;
80% ethanol with 8 times of weight of second filter residue adding boils 20min, steam pressure 0.5-1Mpa, and alcohol reflux stops to reclaim until ethanol＜80% that reclaims, and filters, and gets the 3rd filtrate and filter residue respectively;
First filtrate, second filtrate, the 3rd filtrate are mixed and be concentrated into proportion D=0.8-1.2, promptly get medicinal extract;
Medicinal extract enters spray dryer, and 180 ℃ of EATs, promptly get bamboo extractive dry powder by leaving air temp 75-85 ℃.
The present invention has following remarkable advantages and beneficial effect:
1) is used for the preliminary treatment of cold fresh meat, can plays antibiotic, antibacterial;
2) make meat tenderization, the effect that meat is played flavouring and protects look;
3) shelf-life of the cold fresh meat of prolongation;
The specific embodiment
The raw material leaf of bamboo is cleaned up;
Raw material is packed in the multi-function extractor, through 5 times of water gagings, boil 0.5h, steam pressure is that 1Mpa handles, and filters, and obtains first filtrate and filter residue;
Filter residue boiled 0.5 hour once more through 5 times of water gagings, and steam pressure is that 1Mpa handles, and filters, and obtains second filtrate and filter residue;
80% ethanol with 8 times of weight of second filter residue adding boils 20min, steam pressure 0.51Mpa, and alcohol reflux stops to reclaim until ethanol＜80% that reclaims, and filters, and gets the 3rd filtrate and filter residue respectively;
First filtrate, second filtrate, the 3rd filtrate are mixed and be concentrated into proportion D=0.8-1.2, promptly get medicinal extract;
Medicinal extract enters spray dryer, and 180 ℃ of EATs, promptly get bamboo extractive dry powder by leaving air temp 75-85 ℃.
Bamboo extractive additive Main Ingredients and Appearance is bamboo-leaves flavones 20%-35%, leaf of bamboo polysaccharide 12%-25%.
