## 1 Introduction  
Blue honeysuckle (_Lonicera caerulea_ L.), a perennial shrub in the Caprifoliaaceae family (Juss. ), is commonly referred to as honeyberry, sweetberry honeysuckle, or haskapberry [1, 2]. This species demonstrates broad biogeographical distribution across temperate regions of the northern hemisphere [3, 4]. In its native Chinese habitat, the plant predominantly thrives in northeastern provinces where systematic domestication efforts have yielded numerous improved cultivars. The phytochemical composition of blue honeysuckle berries contributes to their recognized intraraceutical value, with research confirming various bioactive compounds associated with human health benefits [5, 6, 7, 8]. Notably, its organoleptic profile presents a complex flavor matrix characterized by a distinctive bitter undertone that has attracted specific research attention. As a soft-skinned fruit, postharvest preservation poses significant technological challenges, particularly regarding flavor stability and maintenance of characteristic sensory attributes during storage [9; 10; 11; 12]. As a critical quality determinant for consumer acceptance, fruit flavor has prompted extensive investigation into volatile compounds (VOCs) in blue honeysuckle. [PERSON] et al. (2023) [13] employed two-dimensional gas chromatography-ofactometry-mass spectrometry (GC \(\times\) GC-O-MS) to characterize 68 VOCs across eight cultivars, establishing sensory descriptors encompassing fruity, floral, herbaceous, saccharine, and acidic attributes. Their analysis identified six key odor-active constituents: linalool, hexanal, eucalypt, octanal, nonanal, and ethyl 2-methylbutyrate. A follow-up study performed by [PERSON] et al. (2014) [14] carried out longitudinal analyses (2009-2012) on 11 cultivars using GC \(\times\) GC coupled with time-of-flight mass spectrometry (GC \(\times\) GC-TOFMS), revealing 44 terpenoid derivatives with eucalypt, linalool, (+)-limonene, and (+)-\(\alpha\)-terpineol demonstrating high abundance. Ice-temperature (IT) storage, a controlled postharvest protocol maintaining subzero temperatures (typically \(-0.5\)\({}^{\circ}\)C to \(-2\)\({}^{\circ}\)C) while preventing tissue crystallization, has emerged as an advanced preservation strategy in horticultural sciences and food engineering [15; 16; 17]. Its efficacy was systematically demonstrated in stone fruit preservation by [PERSON] et al. (2019) [18], who observed that IT storage extended sweet cherry shelf life by 35% compared to conventional refrigeration. Their biochemical analyses revealed significant maintenance of nutraceutical components, including anthocyanins (\(82.3\pm 1.7\)%), reducing sugars (\(94.5\pm 0.9\)%), ascorbic acid (\(76.4\pm 2.1\)%), and phenolic acids (\(89.2\pm 1.4\)%), alongside mitigation of membrane degradation biomarkers--specifically, membrane permeability decreased by 41.2% and malondialdehydedehyde accumulation was suppressed by 57.8% relative to control groups. By contrast, [PERSON] et al. (2019) [19] conducted volatile organic compound (VOC) profiling on _Prunus armeniaca_ 'Shushanggan' under IT conditions. Through targeted metabolomics, they quantified 10 aroma determinants, notably hexanal and \(\gamma\)-decalactone, showing 68% and 73% retention, respectively, after 28-day storage. Comparative analyses revealed IT storage outperformed both ambient (\(25\)\({}^{\circ}\)C) and standard cold storage (\(4\)\({}^{\circ}\)C) in preserving characteristic aroma profiles. Gas chromatography-ion mobility spectrometry (GC-IMS) represents a cutting-edge analytical technique that integrates orthogonal separation principles through gas-phase electrophoretic mobility differentiation. This dual-dimensional detection system offers distinct advantages, including rapid analysis (\(<\)30 min/sample), parts-per-trillion (ppt) level sensitivity, and non-destructive characterization, without requiring sample pretreatment [20; 21; 22].
