A liquid nitrogen quick-freezing preservation method for fresh bamboo shoots. The method includes performing a coating treatment on cuts of fresh bamboo shoots, which reduces the moisture loss through the cuts, slows down the degree of lignification of the bamboo shoots, mitigates color changes at the cuts, inhibits excessively fast reproduction of microorganisms at the cuts and prevents invasion of microorganisms from the cuts, so that a decrease in nutritional value is reduced, the deterioration of the appearance quality of the bamboo shoots is mitigated, and the nutritional value and commodity value of the bamboo shoots are maintained. The method further includes an intermittent ultrasonic treatment on the fresh bamboo shoots, so that coating substances form films on the surfaces of the cuts more easily, preventing the fresh bamboo shoots from being eroded by microorganisms and preventing nutrient substances from being decomposed and utilized by the microorganisms.

The present specification provides fruit and vegetable products. Also described are methods for producing the fruit and vegetable products.

A method is described for making a treated fruit having improved flavor, texture, and/or yield over thermally pasteurized fruit. The method includes providing a packaged premix that includes fruit with pectin methylesterase, calcium, and sugar, tempering the premix to produce tempered fruit, then treating the tempered fruit with high pressure pasteurization.

The invention discloses a preservation method for fresh blueberry, and relates to the preservation technique field of blueberry. The preservation method of the invention comprises the following steps: step (1): soaking fresh blueberries in an aqueous sodium alginate solution, taking out and drying; step (2): soaking the fresh blueberries treated in step (1) in an aqueous solution containing ε-PL and N,O carboxymethyl chitosan, taking out and drying; step 3: repeating steps (1)-(2). According to the invention, multilayer edible film is coated on the surface of blueberry, so as to extend the storage period of blueberry, thus avoiding the rot and deterioration of blueberry during storage.
