Problems solved by technology

Low temperature preservation can extend the storage period of blueberries to a certain extent, but to achieve longer storage and transportation must be supplemented by other means
②Modified atmosphere preservation: Research has found that high concentrations of O 2 It can significantly inhibit the respiration rate and ethylene release rate of blueberry fruit, and delay fruit aging; use 2.5kPa O 2 +15kPa CO 2 The controlled atmosphere conditions can prolong the storage life of rabbit eye blueberries for more than two weeks, but these are artificial controlled atmosphere preservation methods, and a certain proportion of gas needs to be filled in the storage process, resulting in higher costs
③Chemical preservation: Experiments were conducted on blueberries with allyl isothiocyanate (AITC). The results showed that AITC treatment at 10°C could effectively delay the rot of blueberry fruits. Make chemical control technology face severe challenges
In addition, scholars at home and abroad have also used high-voltage electrostatic fields, UV-C radiation, and edible coatings to keep fresh. There is no research report on the method of blueberry e-commerce preservation

Abstract

The invention discloses an electrical business logistics freshness retaining method for blueberries. The method comprises the following steps: (1) performing ozone gas closed sterilization treatment on blueberry fruits; (2) performing low-temperature and low-pressure treatment on the blueberry fruits treated in the step (1); (3) packaging the blueberry fruits treated in the step (2) by independent small packaging boxes with ventilating holes, and intensively putting the boxes into a sizing foam case, wherein a perforated thin film bag is lined in the sizing foam case and can cover all the small packaging boxes after a bag opening is tightened, and cold storage agents are arranged outside the perforated thin film bag and are positioned at the upper part and the bottom in the sizing foam case; and (4) after the sizing foam case is sealed, putting the sizing foam case into logistics transportation until the transportation is ended.

Description

technical field [0001] The invention relates to a fresh-keeping method for blueberries, in particular to a fresh-keeping method for e-commerce logistics of blueberries. Background technique [0002] Blueberry (blueberry), also known as lingonberry, is one of the emerging small berries in China in recent years. Blueberry fruit is suitable for sweet and sour, with unique flavor and rich nutrition. It has health care functions such as preventing brain aging, anti-cancer, enhancing body immunity and improving eyesight. one. Blueberry fruits generally ripen in summer, when the field heat and respiratory heat are high, the respiration of postharvest fruits is enhanced, and various physiological metabolisms are accelerated, resulting in blueberry fruits that are not resistant to storage, and the storage period at 20°C is only about 1 week. The postharvest quality decline of blueberries is mainly manifested in fruit dehydration, decreased hardness, soft flesh, pedicle scars are su...
