The present invention provides a fluid-outlet-section sealing structure that includes: a fluid outlet section, a sealing member, and a sealing film. The fluid outlet section has a fluid flow channel and an open-end surface. The open-end surface of the fluid outlet section is formed at a fluid outlet end of the fluid flow channel of the fluid outlet section. The sealing member is provided in the fluid flow channel of the fluid outlet section. The sealing film is provided to cover the fluid flow channel of the fluid outlet section and the open-end surface of the fluid outlet section. The sealing film is thermally adhered to the open-end surface of the fluid outlet section and the sealing member.

The invention provides a plastic sheet with a bending grid line, a grid line knife used for the plastic sheet and a packaging container. According to the invention, the rebound resilience of the plastic sheet, which is bent along the bending grid line, is not reduced, and the plastic sheet with the bending grid line having good bending performance and bending intensity can be obtained. The bending grid line is attached to the plastic sheet via the grid line knife, and the grid line knife is formed by arranging a concave knife part on a top surface at the front end. The concave knife part is extended along a direction, which tilts a specific angle toward the attachment direction of the bending grid line, and a convex part of the bending grid line is protruded from the surface of a bottom part of a bending section, and is extended and arranged along the direction, which tilts a specific angle toward the attachment direction of the bending grid line.

The invention discloses a preservation method of dendrobium officinale. The method comprises the following steps: (1), washing picked fresh dendrobium officinale with water at 1 to 4 DEG C, and then cooling the dendrobium officinale to be 0 to 2 DEG C; (2), laying the cooled dendrobium officinale into a preservative at 1 to 4 DEG C, so as to perform soaking treatment on the dendrobium officinale; (3), draining off the soaked dendrobium officinale at 30 to 60 DEG C; (4), performing sealed package on the drained dendrobium officinale, and then storing the dendrobium officinale at 0 to 20 DEG C. The method can effectively keep the original components, color and brittleness, ensures low weight loss ratio, and guarantees the commodity value of dendrobium officinale; the preservation effect is good, the preservation time is long, the method is simple to operate, and the cost is low.

The invention provides a fruit packaging box, accordingly the buffering capability of the fruit packaging box can be improved, vibration impacts on fruits are greatly reduced, the situation of fruit extruding and crushing is reduced, and the commodity value is ensured. The fruit packaging box comprises a box body, a lining and a packaging bag. The fruit packaging box is characterized in that the lining comprises two or more parallel supports arranged at intervals, the supports are arranged in the box body, each support is provided with first clamping gaps, and the first clamping gaps downwardsextend from the tops of the supports; the packaging bag is made of a soft material, the packaging bag comprises a wrapping part storing the fruits and supporting parts connected to the two ends of the wrapping part, the supporting parts are clamped in the first clamping gaps and supported at the bottoms of the first clamping gaps, the packaging bag and the supports are fixedly connected, and thewrapping part storing the fruits can be suspended in space between the adjacent supports.

The invention discloses blueberry jam added with citrus peel and a preparation method thereof. The blueberry jam comprises the following components in parts by weight: 5-10 parts of citrus peel, 40-50 parts of blueberry fruits, 45-55 parts of white granulated sugar, 25-80 parts of water, 0.5-1.0 part of citric acid and 0.1-1.0 part of malic acid. The blueberry jam added with citrus peel disclosed by the invention has the following beneficial effects: the nutrition and mouthfeel of the blueberry jam are enriched, so that the healthcare effect is better; an artificial thickening agent is not needed to be added, and natural pectin and the like in the citrus peel are utilized, so that the blueberry jam is thick and uniform, and convenient to coat for eating; thirdly, an ultrasonic device is adopted under an acid-deficient condition to assist pre-melting of the pectin, so that the dissolution rate and utilization rate of the pectin substance in citrus peel powder are improved; fourthly, the stability of blueberry anthocyanin is strengthened, flavone substances contained in the citrus peel can delay photolysis and thermal decomposition of the anthocyanin in a storage period, so that the value of goods is ensured; fifthly, the whole process is more energy-saving and environment-friendly, so that the cost is saved.

The invention discloses a biological preservative for cherry and tomato fruits and use thereof. Per L of biological preservative is prepared from 1*10<10>-1*10<12> rhodotorula glutinis cells, 400-600mg of rhamnolipid and the balance of water. The rhodotorula glutinis cells are rhodotorula glutinis (Rhodotorula glutinis) ZJU11; the preservation number is CGMCC NO.3589; the rhamnolipid is concentrated rhamnolipid of which the glycolipid content is 70-90%. By using the biological preservative for cherry and tomato fruits, not only can decaying of the cherry and tomato fruits be delayed, but also the quality of the cherry and tomato fruits can be ensured.
