Problems solved by technology

[0006] At present, my country basically still uses mechanical low-temperature storage and chemical agents to preserve fresh fruits and vegetables. However, low-temperature storage is costly, energy-consuming, and unstable in quality; chemical treatment will bring health hazards and environmental pollution.

Embodiment 1

[0022] After dissolving the pectinic acid with ethanol, add water to prepare a 0.01wt% pectinic acid solution, soak the tomatoes in it for 7 minutes, remove it, air-dry it naturally, put it in a fresh-keeping bag, and place it in a storage room at 25°C; , 4, 8, 12, 16, and 20 days to measure fruit hardness, protopectin, cellulose content and rotten fruit rate, and use water as a control experiment, the results are detailed in Figure 1-4 .

Embodiment 2

[0024] After dissolving the pectinic acid with ethanol, add water to prepare a 1wt% pectinic acid solution, soak the tomato in it for 3 minutes, remove it, air-dry it naturally, put it in a fresh-keeping bag, and place it in a storage room at 25°C.

Embodiment 3

[0026] After dissolving the pectinic acid with ethanol, add water to prepare a 0.1wt% pectinic acid solution, soak the tomato in it for 5 minutes, remove it, air-dry it naturally, put it in a fresh-keeping bag, and place it in a storage room at 25°C.

Abstract

The invention discloses a method for inhibiting softening of fruits after harvesting, and relates to softening after harvesting and fresh-keeping technologies of plant fruits. The method adopts pecticacid treatment to inhibit the softening of the fruit to prolong the preservation time of the fruit, which is characterized in that the fruit is soaked in a pectic acid solution for 3 to 7 minutes, and then taken out and naturally dried. The method has the incomparable advantages by other fresh-keeping technologies, and does not inhibit the establishment of flavor and quality after ripening of thefruits while achieving the preservation effect.

Description

technical field [0001] The invention relates to post-harvest softening and fresh-keeping technology of plant fruit, in particular to a method for inhibiting post-harvest softening of fruit. Background technique [0002] The study of fruit softening has always been a hot scientific issue in the field of postharvest biology. Fruit softening is a very complex developmental regulation process including the degradation of cell walls, changes in contents, respiration rate and other metabolic changes. Its appearance is the decrease of fruit firmness, soft texture and even rot. These changes directly affect the quality of fruits. and commerciality, and also affect fruit transportation, storage and sales. [0003] The current general view is that the decomposition of the pulp cell wall under the action of some hydrolytic enzymes is the main reason for the softening and structural changes of the pulp during fruit ripening and storage. The plant cell wall is a structure composed of c...
