2017 results about "Prawn" patented technology

Prawn is a common name for small aquatic crustaceans with an exoskeleton and ten legs (i.e. a member of the order decapoda), some of which can be eaten. The term prawn is used particularly in the United Kingdom, Ireland, and Commonwealth nations, for large swimming crustaceans or shrimp, especially those with commercial significance in the fishing industry. Shrimp that fall in this category often belong to the suborder Dendrobranchiata. In North America, the term is used less frequently, typically for freshwater shrimp. The terms shrimp and prawn themselves lack scientific standing. Over the years, the way shrimp and prawn are used has changed, and nowadays the terms are almost interchangeable.

Method for extracting krill oil with high phosphatide content from Antarctic krills

The invention discloses a method for extracting krill oil with high phosphatide content from Antarctic krills. The method comprises the following steps: (1) drying fresh Antarctic krills to obtain dry Antarctic krills; (2) performing extraction to dry Antarctic krills for 3 times with organic solvent; (3) mixing the extracting solutions, evaporating the mixed extracting solution to obtain Antarctic krill oil with the phosphatide content of 30-35%; then introducing nitrogen or carbon dioxide to remove the residual organic solvent; and adding polar organic solvent in the Antarctic krill oil, mixing evenly, standing to ensure that the mixed solution performs natural layering; and evaporating the lower solution to obtain the Antarctic krill oil with high phosphatide content, and then introducing nitrogen or carbon dioxide to remove the residual polar organic solvent so as to obtain a product. The extraction technology is performed at a low temperature, thus the red color of krill oil can be maintained and the beneficial ingredients in the product can not be damaged. The invention has high extraction efficiency and good phosphatide accumulation effect. Therefore, the Antarctic krill oil with high phosphatide content can be obtained and other byproducts can also be obtained.

The invention relates to a cultivating technique of cross bred lobster in rice field and pond. The technique is the producing manner which utilizes the shallow water environment in the rice field and is supplemented by artificial measures to plant the rice and cultivate the lobster to increase the profit of the unit rice field area. Since the freshwater cross-bred lobster has low requirements on water and the cultivating place, and fish culture in paddy field is a tradition in a plurality of areas in China, and the economic profit of the unit rice field area can be effectively increased by popularizing the culture of the freshwater cross-bred lobster in the rice field when the profit of fish culture is dropped. The culture of the freshwater cross-bred lobster in the rice field can facilitate weeding and pest eliminating in rice field and save fertilizer and pesticide; and the rice yield of the rice field raising the lobster can be increased by 5percent to 15percent generally. In some areas, in particular the areas of waterlogged lowland, winter macerated fallowland and cold water paddy field, where only single cropping is allowed, the mode of the rice planting and the freshwater cross-bred lobster cultivation in turn is adopted and the economic profit is remarkable.
