Environmental exposure to cadmium induces olfactory neurotoxicity in fire ants and the molecular basis

Cadmium (Cd) exhibits widely olfactory toxicity to animals. We previously reported that Cd exposure induces the transcriptional dysregulation of olfactory marker proteins (OMPs) of the red imported fire ant Solenopsis invicta. However, it is still unclear how environmental Cd exposure-induced deregulation of OMPs affects the olfactory signal transduction and olfaction-driven social behavior of S. invicta. Here, we showed that S. invicta displayed dull sensory perception on bait in Cd-contaminated areas and dietary Cd ingestion by S. invicta reduced the bait search efficiency. We hypothesize that deregulation of OMPs by Cd exposure blocks the olfactory signal transduction in fire ants. Our results indicated the odor binding protein 14 (SiOBP14) was consistently inhibited in antennal sensilla of fire ants across Cd exposure at 0.5, 5 and 50 mg/kg. Function analysis in vitro and in vivo demonstrated that SiOBP14 is essential in perception of S. invicta to bait odorants. Cd-exposed fire ants showed weak odorant receptor neurons (ORNs) chemosensory signaling and electroantennogram (EAG) response. Moreover, Cd exposure repeals the preference of S. invicta to the active bait odorants, including 2-methyltetrahydrofuran-3-one, 2-methyl-3-furanthiol and 4,5-dimethylthiazole, and even triggers a behavioral transition from preference to repellence. These results indicate that Cd exposure inhibits the specific OMP expression and disrupts olfactory signal transduction, thereby inducing dull sensory perception of S. invicta to bait odorants. The findings provide new implications for monitoring and control of agricultural insect pests in heavy metal polluted areas.

Sensory Perception Systems and Machine Learning Methods for Pesticide Detection in Fruits

In this study, an electronic tongue (E-tongue) and electronic nose (E-nose) systems were applied to detect pesticide residues, specifically Preza, Daconil, Curzate, Bricol, Accros, Amistar, and Funlate, in fruits such as cape gooseberries, apples, plums, and strawberries. These advanced systems present several advantages over conventional methods (e.g., GC-MS and others), including faster analysis, lower costs, ease of use, and portability. Additionally, they enable non-destructive testing and real-time monitoring, making them ideal for routine screenings and on-site analyses where effective detection is crucial. The collected data underwent rigorous analysis through multivariate techniques, specifically principal component analysis (PCA) and linear discriminant analysis (LDA). The application of machine learning (ML) algorithms resulted in a good outcome, achieving high accuracies in identifying fruits contaminated with pesticides and accurately determining the concentrations of those pesticides. This level of precision underscores the robustness and reliability of the methodologies employed, highlighting their potential as alternative tools for pesticide residue detection in agricultural products.

Molecular mechanisms and behavioral relevance underlying neural correlates of childhood neglect

BackgroundChildhood neglect is associated with brain changes, yet the molecular mechanisms and behavioral relevance underlying such associations remain elusive. MethodsWe calculated fractional amplitude of low-frequency fluctuations (fALFF) using resting-state functional MRI and tested their correlation with childhood neglect across a large sample of 510 healthy young adults. Then, we investigated the spatial relationships of the identified neural correlates of childhood neglect with gene expression, neurotransmitter, and behavioral domain atlases. ResultsWe found that more severe childhood neglect was correlated with higher fALFF in the bilateral anterior cingulate cortex. Remarkably, the identified neural correlates of childhood neglect were spatially correlated with expression of gene categories primarily involving neuron, synapse, ion channel, cognitive and perceptual processes, and physiological response and regulation. Concurrently, there were significant associations between the neural correlates and specific neurotransmitter systems including serotonin and GABA. Finally, neural correlates of childhood neglect were associated with diverse behavioral domains implicating mental disorders, emotion, cognition, and sensory perception. LimitationsThe cross-sectional study design cannot unequivocally establish causality. ConclusionsOur findings may not only add to the current knowledge regarding the relationship between childhood neglect and mental health, but also have clinical implications for developing preventive strategies for individuals exposed to childhood neglect who are at risk for mental disorders.

Asian Carp: Generation Z prefer Transparency over Branding

Asian carp is an invasive species of fish in the Midwest and southern United States. Asian carp has been rebranded as “Copi” for human consumption. Copi is nutritious and a great source of protein and omega 3 fatty acids, and costs much less than most other domestic fish. The purpose of this study was to evaluate sensory perceptions and attitudes of Generation Z college students to the newly branded fish. The study utilized a quasi-experimental design carried out with three treatment groups to observe the effects of product rebranding on the taste perception of Asian Carp, rebranded as Copi. Sensory analysis results indicated no significant differences in the three treatment groups (white fish-control, Copi-experimental, and Asian carp-experimental). In fact, Asian carp had higher mean scores than the control, as well as the newly branded Copi. The importance of Health, Environment, and Local Foods had significant effects on students’ willingness to buy sustainable, local fish. The results of this study are important for marketing Copi, aka Asian carp for human consumption. Keywords: Asian carp, sensory analysis, Copi, Gen Z, branding

Effect of training in a sandy environment on foot morphology and function

BackgroundAthletes need to enhance their foot function to improve their performance and prevent injuries and disability. Although foot function is believed to be improved by stabilizing the body on an unstable surface (e.g., a sandy beach), there have been no relevant studies to our knowledge. Here, we identified the differences in foot and balance functions between beach volleyball and volleyball players and investigated the effects of sandy surface training. MethodsWe included six male beach volleyball players (BVB group) and six male volleyball players (VB group). The following six parameters were measured and compared between the groups: foot morphology, plantar surface perception, isometric ankle muscle strength, toe grip strength, static balance, and dynamic balance. ResultsThe BVB group had significantly higher values in sensation perception, isometric ankle dorsiflexion muscle strength, and toe grip strength in the standing posture, with significant intrinsic foot muscle dominance, compared to the VB group. ConclusionPlaying barefoot increases the amount of tactile information received from the surface of the sole, which may lead to enhanced sensory perception by the foot. In addition, owing to the unstable sandy surface, the intrinsic muscles of the foot and lower leg may strengthen to maintain balance; therefore, training on a sandy surface may lead to improved foot and balance functions.

Sharing Our World: Impact of Group Motor Skill Learning on Joint Attention in Children with Autism Spectrum Disorder.

Impaired joint attention is a common feature of autism spectrum disorder (ASD), affecting social interaction and communication. We explored if group basketball learning could enhance joint attention in autistic children, and how this relates to brain changes, particularly white matter development integrity. Forty-nine autistic children, aged 4-12 years, were recruited from special education centers. The experimental group underwent a 12-week basketball motor skill learning, while the control group received standard care. Eye-tracking and brain scans were conducted. The 12-week basketball motor skill learning improved joint attention in the experimental group, evidenced by better eye tracking metrics and enhanced white matter integrity. Moreover, reduced time to first fixation correlated positively with decreased mean diffusivity of the left superior corona radiata and left superior fronto-occipital fasciculus in the experimental group. Basketball-based motor skill intervention effectively improved joint attention in autistic children. Improved white matter fiber integrity related to sensory perception, spatial and early attention function may underlie this effect. These findings highlight the potential of group motor skill learning within clinical rehabilitation for treating ASD.

Oral processing of bakery products: An overview of current status and future outlook

Food oral processing (FOP) is an emerging research topic that allows a better comprehension of the relation between intrinsic food factors (physicochemical and sensory properties), and human physiology and eating behaviours. FOP can then help in the design of novel and healthier food to meet both quality requirements and consumer needs. In this context, this review presents the current state of knowledge and new insights for future research concerning FOP of bakery products. The application of FOP in bakery science is new, with different protocols and related evaluation being applied, as detailed in this review. The current knowledge shows that bread structure and texture, influenced by formulation and process conditions, as well as the crust and shortenings present, impact bread breakdown and bolus formation, sensory perception, and food physiological effects such as glycaemic response, satiation, and satiety. For a better comprehension of oral processing, cross-modal perception between sensory attributes is used to understand consumer perception and this is carried out using both in vivo, and in vitro methods. This review highlighted the great potential of FOP to assist researchers and producers to face the current challenges relating to i – salt, fat and sugar reduction in bakery products to fulfil current food nutrition policies, ii – the design of healthier bakery products, and iii – the development of bakery products for consumers with special dietary requirements and ageing needs. In conclusion, FOP shows great potential to assist in the development of novel and healthier foods to meet actual food nutrition policies and consumer needs and should be more explored in bakery science and production.

Sensory room: Naturalistic assessment of auditory and visual perception in developing children

IntroductionHearing is essential for language acquisition and understanding the environment. Understanding how children react to auditory and visual information is essential for appropriate management in case of hearing loss. Objective and subjective assessments can diagnose hearing loss, but do not measure natural perception in children. We developed a “sensory room” for complementary assessment of children's perceptions so as to assess behavioral responses to meaningful natural sounds and visual stimuli in an ecologic environment suited to children. Material and methodsSixteen normal-hearing children and 10 with congenital hearing loss before cochlear implantation, aged 13 to 32months, were included in this feasibility study. They perceived 18 environmental sounds and 9 visual stimuli, and their behavioral responses were coded accordingly as: stopping, looking, moving, pointing, language or emotional reactions. ResultAll children completed the task, demonstrating its feasibility in children. Percentage responses to auditory versus visual stimuli did not differ in normal-hearing children; those with congenital hearing loss responded like normal-hearing children to visual stimuli, but did not react to auditory stimuli. Progression in normal-hearing children's behavioral responses corresponded to cognitive and linguistic development according to age. ConclusionThe “sensory room” quantified children's responses to various auditory and visual stimuli, providing clinicians with measurable insight into the children's sensory perception and processing.

Ketamine and α-Amino-3-Hydroxy-5-Methyl-4-Isoxazolepropionic Acid (AMPA) Receptor Potentiation in the Somatosensory Cortex: A Comprehensive Review.

Ketamine, a dissociative anesthetic primarily recognized for its antagonism of N-methyl-D-aspartate (NMDA) receptors, has gained significant attention for its rapid antidepressant effects and potential in treating mood disorders. However, recent research indicates that ketamine's influence extends beyond NMDA receptor inhibition, affecting α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors and sensory processing. This review delves into ketamine's role in enhancing AMPA receptor function and its implications for sensory processing within the somatosensory cortex. AMPA receptors, essential for fast excitatory neurotransmission and synaptic plasticity, play a key role in sensory perception and integration. By examining preclinical and clinical studies, this review sheds light on how ketamine's modulation of AMPA receptors may improve sensory processing and contribute to its therapeutic effects. Additionally, the review explores the potential for ketamine-based therapies to treat sensory processing disorders and refine current treatment strategies. A deeper understanding of ketamine's complex effects on AMPA receptors and sensory processing could provide valuable insights for developing targeted interventions and advancing clinical applications.

Consumers' familiarity with wine increased their acceptance of pasta sauce containing grape pomace.

Grape pomace (GP) is a waste product of the winemaking process and has been proposed as a nutritionally beneficial ingredient, as it contains phenolic compounds, dietary fiber, and antioxidant activity. It can be a polarizing ingredient due to its flavor components. Familiarity has been found to influence consumers' preferences and sensory perception of food. A sensory test was conducted to evaluate the acceptance, sensory perception, and emotional response to pasta sauces containing GP (3% [3GP], 6% [6GP], 9% [9GP] by volume and control without GP addition). The sensory trials included wine consumers (n=44) and nonconsumers of wine (n=58) to determine how consumers' familiarity with the flavor properties of GP influenced their perception of the pasta sauce. Overall, the addition of GP decreased the liking scores of the GP-containing sauces, but the wine consumers' hedonic scores for the control, 3GP, and 9GP were significantly higher than the nonconsumers. Both consumer groups identified that the samples with a higher amount of GP addition were associated with sour, bitter, astringency, grainy, and gritty attributes. However, the wine consumers used more positive emotions to describe their emotional response to the GP-containing samples. The study identified that GP led to off-flavors and textures in the pasta sauces. PRACTICAL APPLICATION: GP is currently a waste product, but it has many nutritional benefits. Consumers are increasingly looking for nutritional benefits from their food. When incorporated into pasta sauces, GP decreased the acceptance of the pasta sauce and negatively impacted the flavor and texture. Familiarity has been found to impact consumer acceptance, and wine consumers had a more positive emotional response and higher hedonic scores in response to the GP-containing pasta sauce than nonconsumers of wine.

Le primat du phallus, talon d’Achille de l’appareil psychique ? Réflexions autour du cancer de la prostate

ContextThe clinical study of prostate cancer, particularly from a psychopathological perspective, remains relatively underexplored yet it serves as a site for serious and often lasting questioning of the erectile capacities of the penis, and thus potentially of the phantasmatic investments it is subject to. Moreover, this common cancer is particularly linked to the issue of aging, which radically tests the fragilities and narcissistic resources of patients. Power, performance, endurance, and counter-investment against passivity and depression become particularly acute issues in the relationship to oneself, to women, and to men. It then appears essential to delineate the psychological stakes of phallic demand in the articulation between the psychic reality of infantile sexuality and the external realities of aging, illness, and social representations. ObjectivesThis study aims to understand how the traumatic experience of prostate cancer—an acute realization and embodiment of aging and vulnerability—reveals fault lines not only shaped by the primacy of the phallus but also reinforced by societal phallic logic, balancing constraints and ideals. It seeks to discern the fragilities and resources of male narcissism related to phallic demands and their implications. The primacy of the phallus and its associated infantile sexual theory are thus questioned in their organizing or disorganizing roles. MethodThe study is based on a multifaceted methodology: an examination of the taboo surrounding the representation of the male sex in painting, semi-structured interviews, and projective tests conducted with twenty men in their sixties who have been treated for prostate cancer. A case study allows for a thorough and heuristic articulation of theoretical and clinical questions. ResultsHonor and virility emerge as particularly significant narcissistic issues, contributing to a hypomanic masculinity that enables men to shift the stakes of various anxieties (death anxiety, passivity anxiety, and castration anxiety) into the form of another anxiety: a narcissistic death anxiety rooted in virility, the dread of no longer existing as a man in the eyes of others. At the intersection of social, psychosexual, and somatopsychic spheres, prostate cancer thus uncovers a taboo Achilles’ heel. This is composed of unconscious interactions and loyalties between the phallic demand (both internal and external) and a partial dependency on the sensory dimension of erection, necessitating a reevaluation of masculinity, the phallus, and erection independent of sensory perception. InterpretationsSociety reinforces the confusion between the sensory perception of erection and the sense of virility and masculine reassurance on a psychological level through a collective and cultural imagination that associates characteristics of power, endurance, and vigor with a “good” virility, and attributes of vulnerability with a “crisis of virility.” These observations, beyond the scope of organic pathology, could contribute to the broader debate on gender issues, the formation of ideologies, and ultra-virilist movements.

David Julius and Ardem Patapoutian: Pioneers in Sensory Biology and Neuroscience.

Sensory biology is a critical area within neuroscience, exploring how organisms respond to environmental stimuli such as temperature, pain, and mechanical forces. David Julius and Ardem Patapoutian have made landmark contributions to this field by identifying crucial receptors. Julius's discovery of transient receptor potential (TRP) channels, including transient receptor potential cation channel subfamily V member 1 (TRPV1), which detects heat and pain, revolutionized sensory biology and opened new paths for pain management. Similarly, Patapoutian's identification of Piezo channels, which respond to mechanical stimuli like touch and pressure, has deepened our understanding of sensory perception. Their combined work has not only advanced scientific knowledge but also introduced potential treatments for chronic pain and sensory disorders. This paper reviews their contributions and the broader implications for sensory biology and therapeutic developments.

An amygdalar oscillator coordinates cellular and behavioral rhythms.

Circadian rhythms are generated by the master pacemaker suprachiasmatic nucleus (SCN) in concert with local clocks throughout the body. Although many brain regions exhibit cycling clock gene expression, the identity of a discrete extra-SCN brain oscillator that produces rhythmic behavior has remained elusive. Here, we show that an extra-SCN oscillator in the lateral amygdala (LA) is defined by expression of theclock-output molecule mWAKE/ANKFN1. mWAKE is enriched in the anterior/dorsal LA (adLA), and, strikingly, selective disruption of clock function or excitatory signaling in adLAmWAKE neurons abolishes Period2 (PER2) rhythms throughout the LA. mWAKE levels rise at night and promote rhythmic excitability of adLAmWAKE neurons by upregulating Ca2+-activated K+ channel activity specifically at night. adLAmWAKE neurons coordinate rhythmic sensory perception and anxiety in a clock-dependent and WAKE-dependent manner. Together, these data reveal the cellular identity of an extra-SCN brain oscillator and suggest a multi-level hierarchical system organizing molecular and behavioral rhythms.

Treatment with quercetin mitigates polystyrene nanoparticle-induced reduction in neuron capacity by inhibiting dopaminergic neurodegeneration and facilitating dopamine metabolism in Caenorhabditis elegans

In organisms, long-term nanopolystyrenes (PS-NPs) exposure can cause toxicity, including neurotoxicity. Quercetin, the flavonol with extensive distribution within plants, possesses diverse biological activities. Nevertheless, the possible effect of quercetin to suppress PS-NPs-induced neurotoxicity and its associated mechanism remains unknown. Thus, in the present work, Caenorhabditis elegans was utilized as the model animal to investigate quercetin's pharmacological effect on suppressing PS-NPs-induced neurotoxicity and the underlying mechanism. PS-NPs exposure at 1–100 μg/L remarkably reduced locomotion behavior, while only PS-NPs exposure at 100 μg/L significantly decrease sensory perception behavior. Meanwhile, the increase in the number of worms with dopaminergic neurodegeneration was detected in nematodes exposed to 100 μg/L PS-NPs and the decreased dopamine content was observed within nematodes exposed to 10–100 μg/L PS-NPs, demonstrating the function of dopaminergic neurodegeneration and disruption of dopamine metabolism in inducing PS-NPs toxicity on neuron capacity. After 100 μg/L PS-NPs exposure, the 25–100 μM quercetin treatment effectively increased the locomotion behavior and the sensory perception behavior. Developmentally, quercetin treatment (100 μM) remarkably enhanced fluorescence intensity while decreasing worm number with neurodegeneration within BZ555 transgenic strains exposed to 100 μg/L PS-NPs. Physiologically, quercetin treatment (100 μM) significantly enhanced dopamine content within nematodes exposed to 100 μg/L PS-NPs. Molecularly, quercetin treatment (100 μM) notably decreased the expressions of genes governing neurodegeneration (mec-4, deg-3, unc-68, itr-1, clp-1, and asp-3) while significantly increasing the expression of genes governing dopamine metabolism (cat-2, cat-1, dop-1, dop-2, dop-3). As revealed by molecular docking results, quercetin might bind to excitotoxic-like ion channels receptors (MEC-4 and DEG-3) and dopamine secreted protein (CAT-2). Consequently, findings in this work demonstrated that long-term PS-NPs exposure within the μg/L range (1–100 μg/L) was toxic to neuron capacity, which was associated with the enhancement in dopaminergic neurodegeneration and disruption of dopamine metabolism. Notably, PS-NPs-mediated neurotoxicity to nematodes is probably suppressed through subsequent quercetin treatment.

Ulil Albab: An Ancient Methodology for Building Corporate Spiritual Responsibility (CSpR)

Corporate Social Responsibility (CSR) aims to balance economic, social, and environmental impacts, but often lacks spiritual and ethical depth. This research introduces Corporate Spiritual Responsibility (CSpR) using the Ulil Albab methodology, rooted in Islamic tradition. The Ulil Albab method integrates intellectual and spiritual faculties through Zikir (remembrance), Do’a (prayer), Tafakur (reflection), and Tahanuts (seclusion), known collectively as ZDTT. By grounding CSR in spiritual awareness, this approach fosters more authentic and impactful social responsibility. The methodology combines sensory perception, rational thought, heart intuition, and divine revelation, offering a holistic approach to knowledge. Implementing CSpR aligns corporate actions with spiritual principles, ensuring ethical integrity and sustainability. The study explores how CSpR can transform CSR practices, its practical implications, and its role in creating a more ethical corporate culture. CSpR enhances businesses' moral fabric, helping them navigate ethical dilemmas and build stakeholder trust.

Weak signal detection capacity of type-II Morris–Lecar neuron system under presynaptic bombardments

The information encoding mechanism of the neuronal system is quite complex and is sensitive to environmental conditions. Neuronal noise, especially synaptic random inputs, is a natural part of the brain. Theoretical and experimental studies have revealed that noise plays a vital role in signal frequency selectivity and weak sensory input perception of the neuronal system. There is a consensus that sufficiently intense noise can trigger rhythmic brain activity, and these noise-induced oscillations could improve signal processing of the neuronal system, particularly when the external signal frequency aligns with the frequency of the noise-induced rhythm. Such behavior in response to noise in the signal-processing mechanism of biological systems is elucidated by stochastic resonance. In this regard, this paper systematically analyzes the stochastic resonance in a Type-II Morris–Lecar neuron under excitatory and inhibitory background spike bombardments. Our results indicate that Morris–Lecar Type II neurons enhance their signal coding capacity by exploiting background synaptic activity. In addition, it has been revealed that the biological properties of the background synaptic connections of neurons that oscillate at different frequencies, such as delta, theta, alpha, beta, and gamma bands, are different. On the other hand, it has been found that neurons adapt to the properties of pre-synaptic neurons to encode weak signals. This study ensures novel insights into the functional role of background synaptic input in neuronal coding mechanisms by demonstrating a biophysical factor of stochastic resonance via numerical analyses. Furthermore, our results show that the properties of the background synaptic inputs significantly determine what kind of signal to encode or not. These results are an important indicator of the signal frequency selectivity of neurons, such as auditory cells.

Prediction of blueberry sensory texture attributes by integrating multiple instrumental measurements

Blueberry (Vaccinium spp.) texture contributes to consumer satisfaction, shelf-life, and machine harvestability and is now a critical goal in breeding for new fresh market cultivars. The industry commonly uses instrumental methods to phenotype texture, assuming that instrumental measurements correlate with sensory perceptions. However, the relationship between perceived sensory textures and mechanical parameters is not well established. In this study, we characterized the fruit texture profile of 43 blueberry cultivars using nine sensory descriptors and determined the predictability of the sensory attributes using mechanical parameters. The sensory study was done by a trained descriptive sensory analysis panel, and instrumental analysis was performed using flat probe penetration and texture profile analysis (TPA) methods. Differences in the perceived firmness of blueberries were mainly due to springiness, hardness, and snap/crisp attributes. Among the mechanical parameters, maximum force (FM; a flat probe penetration parameter) and gumminess (a TPA parameter) had the strongest correlations with these three sensory attributes. To develop predictive models for the nine sensory attributes, multivariate statistical methods were used. The highest level of prediction accuracy was achieved when all the penetration or TPA parameters were used for model development. The R2 values increased by up to 0.66 compared to using a single mechanical parameter. Springiness, hardness, and snap/crisp were predictable with R2 > 0.5, regardless of the instrumental method used. TPA parameters were more suitable for predicting juiciness while residual skin was only predictable using penetration parameters. Mealiness was not predictable with any instrumental measure (R2 < 0.05). For most of the sensory attributes, the models were able to effectively discern the cultivars with the highest or lowest intensity scores. This study provides a basis for breeding programs to utilize improved estimations of the sensorial texture using diverse mechanical parameters to enhance selection for desired blueberry textures.

Aroma volatiles and sensory quality of organically-grown apple cultivars after dynamic controlled atmosphere (DCA) storage and comparison with CA-stored fruit with and without 1-methylcyclopropene (1-MCP)

Long-term storage of many apple cultivars can be especially challenging for organic production where use of 1-methylcyclopropene (1-MCP), a crop protectant that controls ripening is disallowed. For many cultivars, controlled atmosphere (CA) storage alone, is inadequate for managing disorders and ripening. Dynamic controlled atmosphere (DCA), by determining the pO2 just above the lower oxygen limit (LOL), permits the use of lower pO2 setpoints without any negative impacts of anaerobiosis. Consequently, DCA can replace 1-MCP for maintenance of fruit quality. The goal of this study was to determine where this held true for a selection of old and new release organically-grown cultivars in the context of sensory perception. Cultivars included ‘Enterprise’ and ‘GoldRush’ harvested in 2018 (year 1), and ‘Honeycrisp’, ‘Golden Delicious’, ‘Jonagold’, and ‘Fuji’ harvested in 2020 (year 2). The LOL was monitored for DCA using chlorophyll fluorescence (CF) and compared with conventional static CA with or without 1-MCP treatment at harvest. DCA storage suppressed ripening to a similar level as 1-MCP plus CA in both years as indicated by reduced ester biosynthesis and, for some cultivars, maintenance of flesh firmness. However, ripening suppression did not impact the overall sensory preference of ‘Enterprise’, ‘Honeycrisp’, or ‘Fuji’, as all cultivars retained firmness and tartness regardless of storage regime and even negatively impacted it for ‘Goldrush’, an especially tart and firm cultivar. Sensory liking of ‘Golden Delicious’ and ‘Jonagold’ which have more typical diminishing firmness and acid profiles were most benefited by either 1-MCP treatment or DCA storage. The results highlight that use of storage technologies that suppress ripening beyond conventional CA storage are best employed on cultivars with more conventional softening and acid metabolism profiles as opposed to new cultivars that were selected primarily against these ripening phenotypes. The results also demonstrate the value of sensory evaluation compared with instrumental measurements to reveal the influence of different storage regimes on human perception.
