Abstract

The invention discloses a fresh-keeping processing and packaging process for lotus seeds. The process comprises the following steps: draining fresh lotus seeds for 1 h, and precooling the lotus seeds in an air-cooled cold storage at 0-2 DEG C for 24 hours, until temperature at the lotus seed center drops to 2 DEG C; stripping the lotus seeds off seedpod of the lotus, and keeping the cyan skin; immersing the cyan lotus seeds with a chlorine dioxide solution with concentration of 100ppm for 15 min, taking out the lotus seeds, and rinsing the lotus seeds with clear water for 5 min; immersing the lotus seeds into a mixed solution containing 25% of VC and 0.5% of citric acid for 10 minutes, with temperature of the immersion solution controlled at 0-4 DEG C, taking out and draining the lotus seeds; and filling the cyan lotus seeds without any water on the surface into a box, and packaging the fruits by a controlled atmosphere packaging method. According to the above process provided by the invention, a fresh-keeping period of the lotus seeds is prolonged from an original 15 days to 3 months, without loss of appearance, color or taste of the lotus seeds.

Description

technical field [0001] The invention relates to the fresh-keeping field, in particular to a lotus seed fresh-keeping processing and packaging process. Background technique [0002] Lotus seed is a traditional specialty in many parts of our country. In the 1990s, the output was about 5,000 tons. Hunan, Hubei, and Jiangxi provinces are the most important lotus seed production bases in my country. In the past, the lotus seeds planted in our country were mainly supplied for export, mainly for storage of shell lotus and sale of meat lotus. The lotus shell is hard, waterproof and insect-proof, and has good storage stability. Even if it is stored for two or three years, it will not affect the quality of the lotus meat much. In recent years, the domestic economy has developed rapidly, and the demand market for lotus seeds has been expanding day by day. However, it is not easy for shell lotus to be distributed and processed in the place of sale. Dare to process in large quantities,...
