Problems solved by technology

The production method of the Antarctic krill dried product directly cooks or steams with water. Since the Antarctic krill contains a large amount of shrimp oil, it is very easy to oxidize in the subsequent hot air or sun drying process, resulting in browning and odor loss. In addition, During the cooking or steaming process, Antarctic krill is very easy to deca

Abstract

The invention discloses a production technology of dried antarctic krill. The production technology comprises the following steps of (1) classifying fresh antarctic krill according to the specification, thoroughly cleaning the classified antarctic krill, and performing draining; (2) adding a composite antioxidant and a composite preservative to water, and then performing uniform stirring to obtaincooling liquid; (3) adding the antarctic krill with the same specification in the step (1) to the cooking liquid, performing heating to 90-95 DEG C, and performing micro-boiling cooking for at least30min; and (4) filtering the cooked antarctic krill in the step (3), performing cooling, putting the cooled antarctic krill in a vacuum freeze drying machine, then sequentially performing vacuum prefreezing, vacuum sublimation drying and vacuum parsing drying until the moisture content is 25-30%, and then performing vacuum packing so as to obtain dried antarctic krill products. The technology of the dried antarctic krill is simple in steps, high in maneuverability and low in energy consumption, and the obtained dried antarctic krill is good in appearance and quality. The antarctic krill has certain elasticity, and is delicious and chewy in mouth feel and long in storage period.

Description

technical field [0001] The invention relates to the technical field of aquatic product processing, in particular to a production process of dried Antarctic krill. Background technique [0002] Antarctic krill is usually the guide giant krill, which belongs to the genus Krill in the family Krillidae of the order Crustacea Krilla of the phylum Arthropoda. Antarctic krill itself is also rich in protein, mineral elements and a variety of unsaturated fatty acids such as EPA, DHA, etc., which have good medical and health functions for the human body. In addition, Antarctic krill also contains a variety of active ingredients, such as enzymes, chitin and astaxanthin, etc. These substances are conducive to the development of high value-added products of Antarctic krill, which greatly improves the comprehensive utilization of Antarctic krill resources Rate. At present, the main products of Antarctic krill include Antarctic krill powder and Antarctic krill oil, in addition to primary...
