Description
Technical field
The present invention relates to the fresh-keeping water-loss reducer of a kind of prawn, belong to aquatic products processing technical field.
Background technology
Prawn belongs to Arthropoda, Branchiata, Crustachia, Malacostraca, Decapoda, swimming suborder, Penaeidae, Penaeus.The whole world has 28 kinds, and the Atlantic Ocean, America bank has 7 kinds, 6 kinds, Pacific Ocean bank, totally 14 kinds, India-Western Pacific, the Pacific Ocean and a kind, Mediterranean, a kind, West Africa.In state-owned 10 kinds, dwell in the torrid zone, shallow sea, subtropical zone.Prawn can divide sedentariae (as japonicus, furrowed prawn, European prawn etc.) and migration type (as Chinese prawn, banana prawn, penaeus penicillatus), and last class is dwelt in littoral shallow sea, often slips into daytime at husky the end, does not do large-scale movement; A rear class is dwelt in the muddy marine site of bank, river mouth, and normal work is moved and migration on a large scale.Prawn is mainly food with benthonic invertebrates, as Polychaeta, small-sized shell-fish and bivalve etc., sometimes also catches zooplankter.At present, the kind of cultured prawn mainly contains: the new prawn of cutter volume (Matapenaeus ensis) etc. of the japonicus (Penaeus japonicus) of Penaeus, penaeus penicillatus (P.Penicillatus), Chinese prawn (P.orientalis), Penaeus monodon (P.monodon) banana prawn (P.merguiensis), green tiger prawn (P.semisulcatus) and new Penaeus.
Prawn is nutritious, and its meat is soft, easy to digest, in poor health and need the people taken good care of to be fabulous food after being ill; Containing abundant magnesium, to cardiomotility, there is important regulating action, well can protect cardiovascular system, reduce blood cholesterol level, prevent artery sclerosis, simultaneously can also coronary artery dilator, be conducive to preventing hypertension and myocardial infarction; Be rich in phosphorus, calcium, especially have help effect to children's, pregnant woman; Astaxanthin in prawn body is the strongest a kind of antioxidant found at present, is widely used in cosmetics, food adds and medicine.The traditional Chinese medical science is thought, seawater shrimps wet, sweet-salty warm in nature, enters kidney, the spleen channel; Have tonifying kidney and strengthening yang, logical breast be antitoxin, the controlling nocturnal emission with astringent drugs that nourishes blood, dissolving blood stasis and detoxication, beneficial gas grow sun, remove obstruction in channels to relieve pain, effect such as to reduce phlegm of whetting the appetite; Be suitable for the patients such as impotence due to deficiency of the kidney, seminal emission premature ejaculation, alactation, arthralgia and myalgia, tetany, whole body itch, skin ulcer, in poor health and neurasthenia.
In prawn moisture and protein content higher, very easily fishing for, transport, to process and putrid and deteriorated because of bacterial reproduction in storage; Meanwhile, prawn contains a large amount of polyphenol oxidase, and in easy catalytic body, polyphenols reaction, produces melanin, cause the black change of shrimp, cause the decline rapidly of sensible quality, and therefore prawn is a kind ofly difficult to fresh-keeping raw materials of marine products.In order to prevent the freshness of prawn from declining, corrupt blackening, extends its freshness date, must study prawn preservation technique.
Prawn is processed into peeled shrimp, preserve under freezing conditions, transport, become the important component part of prawn industry, in chilled storage process, in peeled shrimp, Free water is freezed, moisture departs from shrimp body through sublimation, in packaging bag, form ice crystal, cause prawn surface to shrink, turn white, that is the drying loss of prawn, not only alleviate product weight, also reduce product quality.At present, generally reduce drying loss by water-loss reducer, quality and the water-retaining property quality of freezing shrimp meat product are closely related.
In order to extend prawn fresh keeping time, reduce drying loss, some enterprises add sulfur-bearing, phosphorus containing components in violation of rules and regulations, play the effect of fresh-keeping water conservation, but sulfur-bearing, phosphorous product are to human health, and contaminated environment, do not reach export requirement, therefore develop natural, green fresh-keeping water-loss reducer and have great importance yet.
SKGM (Konjac Glucomannan, KGM) is a kind of HMW, the non-ionic water-soluble polysaccharide that extract from the stem tuber of konjaku (Amorphophallus konjac C. Koch).The mole ratio of 1:1.6 or 2:3 is pressed with β-1 by D-Glucose and D-MANNOSE residue, the long-chain molecule of 4 glycosidic bond combined polymerizations, exist with mucus shape glucan particulate forms, have the several functions character such as good water imbibition, thickening property, plasticity, water-retaining property, water absorption can reach 80 ~ 120 times of own wt.Or a kind of dietary fiber of high-quality, has preventing hypertension, reduce blood fat, reduce blood sugar, improve body immunity, anti-ageing, the multiple physiological functions such as fat-reducing.But, at present SKGM degradation product is used for fresh-keeping water-loss reducer and have not been reported.
