A kind of processing method of improving fresh-water fishes leisure goods organoleptic quality
(1) technical field
The present invention relates to a kind of fresh-water fishes leisure food processing method.
(2) background technology
Since the nineties in 20th century, progressively formed a novel processed food kind---leisure food in the food industry.This is described as the important innovations of 20 th century later food industry by domestic and international food brainstrust, also be 21 century food industry give priority to one of direction.Why welcome leisure food is, because it meets the requirement of people's daily life, be the companion of not busy feelings refined interests or tastes, be a kind of enjoying type food, increase the snacks of gourmet's luck, be a series products that enriches people's quality of life, it improves with people's living standard and progressively grows up.
Fresh-water fishes are not only nutritious, and tasty mouthfeel, meat are tender, are than the high-energy food that is easier to digest, thereby all-ages edible, but because its spur is more and very easily corrupt again spoiled rotten, and the safety of accommodating is edible brings certain difficulty.It is all good that fresh-water fishes are processed into a series of colors, and be convenient for carrying, the processed food of long shelf-life, will be subjected to very much consumer's welcome.But for a long time, processing of aquatic products is the weak link that aquatic products is produced in China always, and raw material availability and added value of product are lower, and fresh-water fishes deep processing research application is less, less its instant leisure product of seeing on the domestic market.
Occurring at present more in the research is to be major ingredient with low value fish or small fish, is auxiliary material with starch, white sugar, salt, spice etc., through the granular leisure food of mixing, slaking, compression moulding.Fresh-water fishes are processed the adult fish granule product not only enlarged product category, and preserved original nutriment of fresh-water fishes, but production technology fails effectively to be improved always, in the maturing process flesh of fish mouthfeel and fishbone soften can not obtain effectively unified, the finished product color and luster is bad, organoleptic quality is low, and the shelf-life is short.Many researchers test and study drying means and time, baking or life technologies such as frying temperature, sterilization, but problem is not still effectively solved.
Utilize abundant low-value freshwater fish to make raw material, research and develop that a series of form uniquenesses, mouthfeel are excellent, the deep processing of good market prospect leisure goods and technology, increase the kind of market aquatic products, satisfy consumer demand, improve the fresh-water fishes added value, further develop culture fishery, become current pressing for.
Along with the rhythm of life of people in the modern society is accelerated, diet time shortens, the leisure food of nutritious no fishy smell will more and more be subjected to consumer's favor.In recent years, Japan is development and production fish grain leisure food, and product is received by the market very much.China also engenders some flesh of fish leisure goods Research on processing technology, but because process technology does not obtain fine solution, fresh-water fishes spur is many, mud fishy smell is heavy, and easily corrupt in the process, difficulty of processing is bigger, and the shelf-life is shorter, at present fresh-water fishes leisure goods are few on the domestic market, in research and the production process general adopt technological process be: auxilliary batching (frying) → moulding → baking → cooling → packing of pretreatment of raw material → clean → adopt meat → remove raw meat → drain → boiling → add.This technology can not effectively be softened fishbone under the condition that guarantees flesh of fish mouthfeel, promptly old as if then oppressing with duration in the maturing process, and the time spent, short then fishbone can not soften, and influenced the product mouthfeel; The product color heterogeneity influences visual perception's quality; Shelf life of products is short, is difficult for preservation.This solves problem with regard to a kind of new technology of needs, improves product quality, extends the shelf life, and enriches the market kind, satisfies the consumer group's demand.
(3) summary of the invention
For reaching above purpose, improve product quality, improve the fresh-water fishes economic worth, the invention provides a kind of method that improves fresh-water fishes leisure goods organoleptic quality, with the low-value freshwater fish is primary raw material, the integrated application foodstuff flavouring, local flavor keeps, modern food processing technologies such as quality-improving, produce high-quality, high added value, popular leisure food, the external form packing is as candy, being rich in nutrition value, it is a kind of innovative aquatic leisure food, high protein, low fat, contain abundant iodine, calcium, phosphorus, element and multivitamins such as iron, polysaccharide has good (the fragrant aquatic foods of flavor of mouthfeel, neither too hard, nor too soft, be with sweet in the one-tenth), (color and luster is good for good visual effect, profile is neat), characteristics such as the shelf-life is long.
The technical solution used in the present invention is:
A kind of processing method of improving fresh-water fishes leisure goods organoleptic quality, described method comprises following sequential steps:
(1) desalination: will soak 12~18h desalination, skimming operation in the mobile clear water of raw material fish immersion; Cross three goes fish (decaptitate, squama, internal organ) by (removing raw meat) in order to clean, to pickle for described raw material fish, perhaps cuts apart the rim charge that the fish piece produces;
(2) cook: the raw material fish after the desalination is packed in the pressure cooker, and pressure 1.8~2.0kg, 120~125 ℃ of constant temperature of temperature steam 20~30min;
(3) decompose deburring: the raw material fish that cooks is poured in the agitator and decomposes, and after treating the flesh of fish and fishbone separating fully, chooses fishbone, oppresses standby;
(4) fishbone is continuous steams: isolated fishbone is packed in the pressure cooker, pressure 1.8~2.0kg, the continuous 20~30min that steams of 120~125 ℃ of constant temperature of temperature;
(5) fishbone is cut and mixed: the good fishbone of continuous steaming is put into to cut and is mixed the device chopped, and making does not influence mouthfeel;
(6) fry perfume: the flesh of fish after step (3) is decomposed and the fishbone of step (5) chopped mix, and add to propagandize hotly to do to add condiment, stir; Described condiment is conventional condiment, as salt, white sugar, chilli powder, zanthoxylum powder, chickens' extract etc., can select to add according to the taste needs;
(7) moulding pelletizing: the material behind the stir-fry perfume (or spice) is filled in the special mould, compression moulding, cooling back pelletizing (generally about 1cm * 1cm * 1cm size);
(8) baking: the fish grain that cuts evenly is tiled in the drip pan, and 150~160 ℃ are toasted 5~10min down;
(9) bag cocoa sugar-coat: the fish grain after will drying wraps one deck cocoa sugar-coat, reach and avoid oppressing the effect that directly contacts, prolongs the preservation time with outside air, and improve fish fruit outward appearance product phase, improve product visual perception quality, cooling, promptly get described fresh-water fishes leisure food, can further after sterilization, packing, sell as finished product.
Concrete production procedure is as follows: raw material fish outbound → cut apart → desalination → HTHP cooks → decomposes deburring → fishbone and continues steaming → fishbone and cut and mix → mix, fry the perfume (or spice) → moulding pelletizing → baking → bag cocoa sugar-coat → bag candy wrapper → sterilization → coding of weighing → seal → outer case packing.
Beneficial effect of the present invention is mainly reflected in: the fish body will be oppressed fishbone and separate after HTHP is cooked, and fishbone continues HTHP and steams to softening, and cuts and mix, to not influencing mouthfeel; This method had both been avoided the undue boiling of oppressing, and can thoroughly soften fishbone again, reached effective product taste quality that improves.At the chocolate flavoured cocoa sugar-coat of flesh of fish grain outer wrapping one deck that processes, avoid the flesh of fish directly to contact with outside air, prolong preservation term, and enrich the product taste, improve outward appearance product phase, improve the product sensory quality.Manufacture craft of the present invention makes the leisure fish color of making various, no fishy smell, and mouthfeel is good, nutritious and instant; Profile is neat, organizes the quality homogeneous, and had normal mastication is bright fragrant moderate, and the peculiar fragrance of the flesh of fish is arranged; Long shelf-life can reach 12 months.
