  • Ice temperature storage has obvious advantages in maintaining food freshness and flavor, but it has strict requirements on storage temperature and requires close to the freezing temperature of food. Because the temperature is too low, it will directly cause food freezing damage, but the temperature will not reach high. Maximize the purpose of food preservation period.

Description

一种香梨多温区冰温保鲜库及保鲜方法 技术领域
本发明涉及果蔬保鲜库与果蔬冰温保鲜技术领域，特别涉及一种香梨多温区冰温保鲜库及保鲜方法。
背景技术
库尔勒香梨皮薄、汁多、味甜、酥香、营养丰富，品质好，但不耐贮藏，常温下存放15天左右其果肉开始变软，果皮失水皱缩，从而商品价值下降。因此，如何更有效地延长香梨保鲜期，保持其原有品质和风味具有重要意义。
现有的香梨保鲜方法主要包括传统的低温冷藏和气调保鲜以及近年来发展起来的冰温贮藏技术等。冰温贮藏是指在0℃以下至冰点温度以上的未冻区域内贮藏鲜活食品，在不破坏贮品细胞结构和不产生冷害的情况下，最大程度地降低活体呼吸速率，抑制病原微生物生长，从而延长食品的贮藏期。冰温贮藏在保持食品鲜度、风味等方面有明显的优势，但它对贮藏温度要求严格，要求接近食品冰点温度，因为温度过低会直接导致食品冻害发生，而温度偏高则达不到最大限度延长食品保鲜期的目的。
中国发明专利申请CN104567198A公开了一种多库房同温冷库制冷系统的设计方法及制冷控制方法，按照现有的冷库热负荷计算法，分别计算n间库房的冷却设备负荷，该负荷适用于n间库房冷却设备的配置，以此负荷为依据乘以修正系数1.1～1.3来进行冷却设备的配置；充分考虑环境温度最高季节、开门次数最多阶段和最大进货量期间对冷库降温速率的影响，并按照最大一间库房冷却设备制冷量配置压缩冷凝机组。本发明的方法可以大大减少制冷系统的一次投入，减少建筑、电力设备等的投资。可以缩小大型冷库制冷系统的体积，较少制冷剂的充灌量，减小了安全隐患及制冷剂的一次投入。虽然该发明专利能够提供一种多库房的冷库，且在建筑、电力设备投资和运行能耗方面有明显的优势，同时该发明制冷系统的设计方法减少了安全隐患、提高了环保性能，但是该发明多库房所设的温度为同温，保鲜效果有限。
中国发明专利申请CN104482703A公开了一种带有一体式制冷系统的多库房冷库，能够根据制冷需要进行制冷；包括库体维护结构、冷库用冷风机、风冷式压缩冷凝机组、横向轨道和纵向轨道，库体维护结构内分隔成多个库房， 每个所述库房前部安装有开启式保温门，冷库用冷风机与风冷式压缩冷凝机组连接组成一体式制冷系统，一体式制冷系统与所述横向轨道和纵向轨道滑动连接，实现多库房移动制冷。该发明冷库多个库房共用一套制冷系统，初投资大大降低。制冷剂充灌量仅为一套制冷系统的充灌量，系统的安全性大大提高。实现冷库的节能运行和库内温度恒定。虽然该发明专利能够提供一种多库房的冷库，也能够根据制冷需要进行制冷，但是该发明没有涉及冰温贮藏技术，贮藏温度没有按梯度下降的规律来设计，容易导致果蔬冷害、冻害发生和品质下降，没有达到保鲜的目的。
发明内容
本发明的目的在于提供一种香梨多温区冰温保鲜库及保鲜方法；贮藏前与贮藏过程中，对香梨冰点温度进行在线检测，并依据检测结果对其进行分级，实行分级贮藏，贮藏温度严格按梯度下降的规律设计，确保香梨始终在近冰点温度条件下贮藏，从而能更有效地防止香梨果实腐烂变质、冻害发生和延长货架期，控制冷害率在1％以下。
冰温贮藏技术最早由日本的山根昭美博士于20世纪70年代发现并提出。之后，冰温技术在日本得到广泛应用，并建立了相应的冰温冷藏链体系。我国从20世纪80年代引进冰温技术的理念，与之原理类似的近冰点贮藏技术先后在大蒜、冬枣、葡萄、板栗等农产品上应用，但应用效果并不是很理想，主要在于冰温贮藏技术涉及的果蔬冰点不易确定，温度稍低会对果蔬造成冻害，反而不利于果蔬的长期贮藏；而温度稍高又不能达到理想的保鲜效果，而且该技术控制温度的难度较大。
现有的冰温贮藏技术对冰点温度的确定主要借助果蔬冰点资料的积累作为参考范围，或以传统方法(如冰盐水浴法)测定结果间接来确定冰点温度。从实际应用的角度来看，通过这些方式所确定的冰点温度不仅结果不够精确，而且实验周期很长，不利于快速控制。
香梨的冰点温度随其糖度不同而差异较大，而糖度与香梨的品种、产地和成熟度等直接相关，一般在10％‐13％区间内，通常糖度高的香梨由于细胞液浓度较高，故冰点温度较低；而糖度低的则冰点温度较高。如库尔勒香梨为新疆名优特产品，其产地广阔；另外，采摘时香梨的成熟度也是不一样的。因此，待贮藏香梨的冰点温度差异较大，所以，如果不考虑个体差异，直接借助香梨冰点资料或通过传统方法测定其他香梨的冰点温度间接来确定待贮藏香梨的冰点温度是不科学的；同时，对不同香梨而言，它们的冰点温度是在一个较大 范围内变化的，因此，如果只是在这个较大范围内选择某个值来设定贮藏温度，很容易导致所设贮藏温度偏高或偏低问题的发生，冰温贮藏效果不明显。
本发明的一种香梨多温区冰温保鲜库安装有冰温在线检测装置，该装置可以直接对所有即将进入冷库贮藏的香梨的冰点温度进行在线检测，从而可以解决通过间接方法来确定香梨冰点温度不科学的问题；特别是，本发明发现，不同香梨冰点温度分布在‐3℃至0℃的范围内，设计4个温度(0，‐1，‐2和‐3)冷库可以实现对不同冰点香梨的分级贮藏，解决贮藏温度偏高或偏低问题，确保香梨始终在近冰点温度条件下贮藏，4个冷库按照温度递减规律逐级连接，可以确保冰点较低的香梨温度缓慢降至近冰点温度，避免快速降温导致香梨品质下降，在限度延长货架期的同时避免冷害的发生效果非常显著，与固定温度的冰温贮藏34％的冷害率相比，本发明只有1％的冷害率。

不同保鲜方法对香梨品质的影响
采摘八成熟(果面光滑，果皮青黄色、阳面微带点红晕)的库尔勒香梨，包装后(用拷白纸包果，外套网袋)装箱，于采收次日运回实验室冷库；挑选无病虫害、果形整齐、大小和色泽基本一致、无表皮损伤的果实400个，随机分为4组，每组100个，4组香梨先分别按照不同保鲜方法处理80天后(第1组为对照组)，再在室温(25℃左右)下放置2天，然后分别测定4组香梨的腐烂率、冷害率、失重率、果皮色泽(亮度)、果肉品质硬度、糖度和可滴定酸。不同保鲜方法分别为：第1组，自然贮藏；第2组，低温冷藏(温度：4℃；湿度：90％‐95％)；第3组，冰温贮藏(多温区，温度分别为0，‐1，‐2和‐3℃)，按步骤S1至S6进行；第4组，冰温贮藏(固定温度：‐2℃)，经 步骤S1至S6后，再将所有自动仓储装置中的香梨移到第三自动仓储装置7‐3。测定结果如表1所示。
表1 不同保鲜方法对香梨品质的影响
Figure PCTCN2017112640-appb-000001
注：发生腐烂和冷害的果实未统计。
如表1所示，与低温冷藏相比，冰温贮藏可以避免香梨果实腐烂的发生；另外，冰温贮藏的失重率都在1％以下，明显低于低温冷藏的失重率(1.83％)，说明冰温贮藏能更好地保持香梨的水分；同时冰温贮藏比低温冷藏能更好地延缓香梨果实硬度和可滴定酸含量下降，也能更有效地延缓果实糖度的上升；在保持香梨果实亮度方面，冰温贮藏(特别是多温区冰温贮藏)的效果也明显优于低温冷藏。总之，不论是从贮品的外部品质来看，还是从内部品质来分析，冰温贮藏的保鲜效果都更出色，冰温贮藏能更好地保持香梨原有品质。就冰温贮藏而言，本发明多温区冰温贮藏的效果要好于固定温度的冰温贮藏；最值得注意的是多温区冰温贮藏几乎可以避免香梨果实冷害的发生，因为多温区冰温贮藏所设定的贮藏温度都是近冰点温度，而固定温度的冰温贮藏所设定的贮藏温度是一个范围内的某个值，在长期的贮藏过程中，冰点温度高于这个值的香梨果实都可能发生冷害；而本发明多温区冰温贮藏比固定温度的冰温贮藏更好保持香梨果皮色泽，原因可能是固定温度的冰温贮藏可能引起部分香梨的冻伤，增加酶与底物接触的可能，并最终导致一些酶促反应发生，引起果皮颜色变化。综上所述，多温区冰温贮藏是香梨贮藏保鲜最理想的方法，与固定温度的冰温贮藏34％的冷害率相比，本发明只有1％的冷害率，具有非常显著的改进效果。为了获得更好的保鲜效果，冰温贮藏技术往往将贮藏温度设得很低，而冷害是现有冰温贮藏技术最主要的问题，本发明在获得最好保鲜效果的同时大大降低了冷害率。
本发明的实施方式并不受所述实施例的限制，其他的任何未背离本发明的 精神实质与原理下所作的改变、修饰、替代、组合、简化，均应为等效的置换方式，都包含在本发明的保护范围之内。
