Instant double-pepper fish head and production method thereof

The invention belongs to the field of aquatic product processing technology, and specifically relates to an instant double-pepper fish head with a freshwater fish head, capsicum frutescens and red pickled peppers as base materials, and a production method thereof. The freshwater fish head (aristichthys nobilis or silver carp), capsicum frutescens, the red pickled peppers, vegetable oil and the like are used as the base materials and are matched with spices, white sugar, table salt, a flavor agent and other auxiliary materials, and the instant double-pepper fish head (normal-temperature circulating sale type) is prepared through the processes of pretreatment, low-temperature low-salt pickling and deodorization, low-temperature air drying and design finalizing, medium-temperature slight deep-frying, double-pepper sauce seasoning, bagging (placing in pallets) and vacuum sealing, high-temperature short-time sterilization, back-pressure water-spraying cooling and the like. The instant double-pepper fish head maintains the texture and the flavor of a traditional chopped pepper fish head, has the shelf life of more than 180 days at room temperature, has fresh, sweet, sour and spicy compound taste, is fresh, tender, tasty and refreshing, and has the characteristics of being rich in nutrition, and convenient to carry and eat.

Method for effectively removing fishy smell of chub surimi

The invention relates to a method for effectively removing the fishy smell of chub surimi. The method comprises the steps of: temporarily feeding fresh chubs in aerated clean water for 12 hours, washing the chubs, then cutting off chub tails and bloodletting, removing scales, heads and internal organs of the chubs, then rinsing fish flesh by clean water, dehydrating the fish flesh, and then preparing the dehydrated fish flesh into surimi by a meat mincer; chopping up fresh fineleaf schizonepeta herb and gingers, then stirring the chopped fresh fineleaf schizonepeta herb and gingers by a juicing machine, and taking fineleaf schizonepeta herb juice and ginger juice for later use; and adding the fineleaf schizonepeta herb juice into the surimi, treating the surimi in a thermostat water bath, then adding tea polyphenol into the thermostat water bath, treating the surimi in the thermostat water bath for 50 minutes, or adding the ginger juice and cooking wine into the surimi, treating the surimi in the thermostat water bath, then adding the tea polyphenol into the thermostat water bath, and treating the surimi in the thermostat water bath to obtain the fishy smell-free chub surimi. In the method, combined fishy smell removing technique is adopted, and the removal ratios of a plurality of main components causing the fishy smell of the chub are close to 100 percent; and the water content, proteins, color and quality of nutrients such as amino acids of treated surimi products are hardly affected. The method has the advantages that: the operation is simple, used raw materials are edible additives, and no residue and pollution are caused; and the fishy smell of the chub is completely removed without affecting the chub flavor.

Method for producing hemepeptide by using red blood cells of animal blood as raw materials

The invention discloses a method for producing hemepeptide by using red blood cells of animal blood as raw materials. The method comprises the following steps of: adding water into the red blood cells of the animal blood, stirring for wall breakage, heating, performing thermal denaturation, adjusting the pH of the obtained mixture to be between 7.5 and 9.0 at the temperature of between 40 and 60 DEG C, adding special enzyme 1122 for blood cell hydrolysis in a ratio of 1,000 to 2,500U / (g protein), performing enzymolysis for 4 to 8 hours with stirring, inactivating the enzyme, filtering, concentrating the filtrate, performing spray drying, and thus obtaining the hemepeptide. According to the method, the red blood cells are subjected to wall breakage and thermal denaturation, so that the double-spiral structure of the red blood cell protein becomes loose, the special enzyme 1122 for blood cell hydrolysis enters the amino acid binding sites in the red blood cell protein more easily to perform enzymolysis, and the enzymolysis rate is improved; and the adopted special enzyme 1122 for blood cell hydrolysis can be used for simultaneous enzymolysis of multiple amino acid binding sites of the red blood cell protein, so that the enzymolysis efficiency and the yield are further improved, and the yield of the whole hydrolysis process reaches over 78 percent.
