Natural antistaling agent, as chitosan, ozone, alginate, tea polyphenols etc, is non-toxic and odorless, biodegradable, biocompatible, low cost, excellent preservation effect, which is becoming a hot on preservation of freshwater fish. Development of natural preservative can not only effectively reduce the cost of storage of aquatic products, promoting economic efficiency, but also improve a lot of negative effects to human health and environment causing by the chemical preservative residual, which has a broad application prospect. The mechanism of natural antistaling agent for freshwater fish was introduced. The applications of natural antistaling agent for the preservation of freshwater fish were reviewed. In addition, some suggestions of the development were presented.

In order to avoid the fish damage and increase gut removal rate in gutting process, optimizting the operation parameters of slitting and gutting institution, adopting gutting effect test with self-developed gutting mechanism with the Lepidotrigla abyssalis for the test object, using the quadratic regression orthogonal rotational combining design, the relationships of acceptability evaluation with transmission speeds, slitting cutter rotation speeds and gutting wheel rotation speeds were studied, and the mathematical model between the acceptability evaluation and operating parameters was established. The result showed that using a toothless disc cutter had the best slitting effect that could achieve a smooth and flat slitting surface and a higher acceptability evaluation. Under the same conditions, converse slitting had a better effect than consequent slitting, the effect degrees of 3 factors on the acceptability evaluation was as following: gutting wheel rotation speeds > transmission speeds > slitting cutter rotation speeds. Through the simulating top-choosing equation, the best parameter combination under the gutting process of Lepidotrigla abyssalis experiment conditions was obtained as following: the transmission speed was 1.39 m/s, the slitting cutter rotation speed was 1280.0 r/min, the gutting wheel rotation speed was 95.0 r/min, and the acceptability evaluation of gutting effect was achieved maximum of 9.98, at this time, which could meet the needs of gutting process.

An experimental study on mechanized gutting for Trachurus japonicus was conducted, faced with equipment shortages for the pre-processing of trash fish. A self-developed test platform was employed for slitting Trachurus japonicus to avoid fish damage and increase the gut removal rate in the gutting process. Preliminary studies showed that the parameters of the slitting cutters had a significant effect on the gutting process of trash fish. In addition, the subsequent operations of gutting were directly determined by the slitting process. The various trash fish gutting operations should be equipped with different parameters of slitting cutters to achieve the best gutting effect. The relationships between gutting effect and cutter external diameter, cutter tooth structure, cutter rotation direction, cutter thickness, and cutter rotation speed were studied. The results showed that cutter external diameter, cutter thickness, and cutter rotation speed were the key factors in the gutting process of Trachurus japonicus. Using a toothless disc cutter had the best slitting effect that could achieve a smooth and flat slitting surface and a higher getting proportion. Under the same conditions, converse slitting had a better effect than consequent slitting, while a high rotation speed was better than a low rotation speed. When the slitting cutter's external diameter was 190.0 mm, it had a better acceptability evaluation of 9.68. The getting proportion had no significance when the thickness of cutter was less than 3.0 mm. With the increasing of the cutter's thickness, there was a tendency of growing weight loss of trash fish during the gutting process, which led to a lower getting proportion. An orthogonal test showed that: The best parameters of the gutting process of Trachurus japonicus were: cutter external diameter 190.0 mm, cutter thickness 3.0 mm, and cutter rotation speed 1100.0 r/min. Under these conditions, the maximum value of acceptability evaluation and getting proportion of gutting effect was achieved, and thus it could meet the needs of the gutting process. The productivity of a mechanized processing method was 8-12 times as much as the productivity of a manual processing method. The study also showed that the gutting effect was closely relevant to the size and body characteristics of the trash fish, so their pre-processing required a heavy workload. However, replacing the manual gutting process with the mechanical gutting process could be achieved through proper size grading and the development of a general fish gutting device with the optimization of slitting cutter parameters. This study can provide reference for the design of gutting equipment for trash fish.
