水果保鲜包装：李子保鲜袋

李果的成熟特点是绿色逐步减退，显出品种固有的色彩（大部分品种的李果外表有果粉，肉质稍变软）。红色品种在果实着色面积为全果的将近一半时为硬熟期，90%着色为半软熟期；黄色品种在果皮由绿转绿白色时为硬熟期，而果皮呈淡黄绿时即为半软熟期。李果采收必须适时，通常中成熟前期采摘采收过早，风味不佳，过于成熟的，果实已变软，不耐贮藏。 
 
李子存储方法：
1、李子装袋：将预冷后的李子整齐码入袋内，剔除有伤口及腐烂蔬果。
2、用手轻轻按压李子保鲜袋，将多余的气体排出。
3、李子袋口用橡皮套扎口，或将多余袋口对折后再扎口。
4、将封好的李子保鲜袋放入干净的纸箱或流转筐内。
5、将装有李子的保鲜袋，整齐码放，确保通风透气，不得挤压李子保鲜袋。

HAIHONG active fruit fresh-keeping bags: After picking, fruits and vegetables are cut off their water and minerals supply. Assimilation is almost stopped, but it is still alive. Life activity is still going on inside, mainly including respiration in metabolic process. The more vigorous the respiration, the quicker various physiological and biochemical processes are, and the shorter the life after picking . That is to say, fruits storage and fresh-keeping mainly include respiration restraining, which should never affect normal metabolic process however. Temperature, gas and humidity are the main factors affecting respiration. Large amount of laboratory test proved that respiration can be restrained by increasing the CO2 content in the air, while reducing that of O2.To most fruits, a CO2 thickness of 1%~5% is suitable. But different fruits have their respective requirements for temperature, ratio of gas content, and humidity. The company developed special and professional active fresh-keeping bags that are proper for the respective features of fruits according to their biological natures, which effectively restrain the respiration of fruits, put it in a sleeping state, and without affecting normal metabolic process. Fruit corruption rate is under 2%, while the weight loses is below 0.5%.
      海宏保鲜包装物理活化水果保鲜袋（膜）：李子在采摘后失去了水和无机物的供应，同化作用基本停止，但仍然是活体，生命活动仍在进行，其主要代谢过程是呼吸作用，而呼吸作用越旺盛，各种生理、生化过程进行的越快，采后寿命就越短。所以西安水果保鲜袋膜水果的贮藏、保鲜主要是抑制呼吸，但不能影响正常的代谢。温度、气体、湿度又是影响呼吸的主要因素。经大量实验证明适当提高空气中的CO?含量，降低O?含量可抑制呼吸。对于大多数水果来说比较合适的CO?浓度为1%~5%。但李子有其特定的温度、气体含量比例、湿度。公司根据李子的生理特性研制出了专业的、适合李子特性的、特定活化保鲜袋，可有效的抑制水果呼吸，使李子达到一种休眠状态，且不干扰李子正常的生理代谢。坏果率在 2% 以下，重量流失在0.5%以下。
