Study On The Technology And Manufacturing Procedure Of Functional Beverage Made From Bee-pollen

Bee-pollen is a kind of valuable natural nutrient resources which deserved to be studied and explored, it is rich in nutrient components that needed by human body, and contains kinds of functional ingredients which are absolutely necessary to our health cause of its special function. However, most of bee-pollen in our country is not taken full used at present. In this paper, the extracting procedure of nutrition in bee-pollen, the optimal proportion of bee-pollen beverage, the application of membrane separation in the clarification of bee-pollen beverage and the color stability of bee-pollen beverage were studied, based of which the manufacturing technology of functional beverage made from bee-pollen, named JNC beverage, were summarized. These studies offer an important practical recommendation for exploring bee-pollen resources.1. The effective way of extracting the nutrients from Corbicular bee-pollen is to break frozen Corbicular bee-pollen by mechanic force combined with the effect of temperature difference, and the optimum technological conditions are as follows: volume ratio of ethanol(5%) to acetic acid(10%) is 30:1, first extracting time is 3 hours, first liquid-solid ratio is 1.5:1, second liquid-solid ratio is 3:1, ethanol concentration is 85%, second extracting time is 3 hours.2. By the orthogonal experiments, the most appropriate proportion of the raw materials in JNC beverage are as follows: Corbicular bee-pollen extract(15°Brix) is 10%, dry royal-jelly is 0.5%, honey(60°Brix) is 12%.3. Using membrane technology(size:0.45um), a clear and stabilized JNC beverage was obtained. This product contains most of the nutrients and functional ingredients in raw materials. The operation conditions of the membrane separation are as follows: V is 0.8 m~3/h, P is 0.2~0.35Mpa.4. Add 0.02% D-VjC sodium can effectively inhibit JNC beverage from color changing, and the product is still stable though it have been kept in storage for more than 180 days.5. The medium scale experiments proved: the technology and manufacturing procedure of JNC beverage concluded in this paper are effective, convenient and viable. Analysis indexes of the final product are in accordance with the set of GB16740-1997 entirely. The final product is microbiologically safe, qualitatively stable, and have the functions of resisting fatigue, developing immunity from disease, sobering up and protecting liver from injuries induced by ethanol.6. The results of this study could be used as the basis for further development in the manufacturing technique of bee-pollen. The ultimately application of this study will definitely improve the value of bee-product, increase farmer's income, develop the bee-raising industry,...
