“…Then, the gradual increase of the K value maybe was due to the increase of ATP degradation rate caused by the autolysis effect and enzymatic reaction in fish muscle during frozen storage (Cela‐Pérez et al . ), which meant that the freshness started to lose on account of the increase of K value. In fact, most of the adenosine nucleotides disappeared quickly since they degraded to IMP within two days after the capture of the fish, and as the degradation continues, HxR and then Hx would be produced.…”

Fish is highly perishable and frozen storage is normally used to maintain its quality. This study employed freezing‐thawing (F‐T) cycles to simulate the abuse in frozen storage conditions, and their effects on the quality changes of grass carp fillet were investigated. Results indicated that with the increase in F‐T cycles, the hardness exhibited an increase during cycle 0 and cycle 1 and then decreased in the following two cycles. Measurement points had little influence on textural properties. Total volatile basic nitrogen (TVB‐N) value showed an increase from 8.72 to 22.55 mg N/100 g during four F‐T cycles, while thiobarbituric acid reactive substances (TBARS) exhibited gradual increase with the cycles and K value was also increased from 20.57 to 76.29% with the cycles. The results demonstrated that frozen storage condition abuse showed an important effect on textural properties and TVB‐N, TBARS and K value of grass carp fillet. Practical Applications Investigations of fish and fish fillet freshness are much more significant in research and development for providing premium quality for the acceptance of consumers as well as international fishery trade. However, little work has been reported about the frozen storage condition abuse on textural and chemical properties of grass carp fillet. Therefore, in the current study, freezing‐thawing cycles were used to simulate the temperature abuse during frozen storage, and their effects on the quality changes of grass carp fillet muscle based upon fish textural parameters were investigated. The results should provide practical guidance for the fish industry.

“…As a final point, MIP 6 has been chosen as adsorbent for the enrichment and separation of HYP and other ATP degradation products such as INO from natural fish matrices [23].…”

“…The study has been divided in two articles: part I, the current paper, involving MIP design and characterization and part II describing the application [23]. So far, to the best of our knowledge, there is only one work dealing with HYP based MIP in which the target analyte itself is used as T to prepare a MIP membrane to be applied as electrochemical sensor characterized by its detection speediness [24].…”

“…Notwithstanding, the MIP sensor does not tackle the ''bleeding'' issue which causes serious interferences when applied to quantitative analysis in real samples nor has it been tested in fish samples and its performance in biological matrices is unknown. Besides, our method, which is particularly remarkable for the instrumental simplicity and low cost, allows the selective extraction and purification of inosine in addition to HYP, both ATP derivatives present in fish samples [23].…”

“…These systems are the detection of tetrahydrocannibinol (THC) using a Catechin–hydrate MIP with acrylamide as FM (case study 2) and the detection of Bisphenol A and Bisphenol F using a Bisphenol A MIP with 4‐vinylpyridine as the FM (case study 3) both of which are discussed in detail in the supporting information. The first case, involving the detection of hypoxanthine, a metabolite of adenosine triphosphate (ATP) from food products using a selection of theophylline MIPs is detailed in brief below.…”

Molecularly Imprinted Polymers (MIPs) are highly advantageous in the field of analytical chemistry. However, interference from secondary molecules can also impede capture of a target by a MIP receptor. This greatly complicates the design process and often requires extensive laboratory screening which is time consuming, costly, and creates substantial waste products. Herein, is presented a new technique for screening of "virtually imprinted receptors" for rebinding of the molecular template as well as secondary structures, correlating the virtual predictions with experimentally acquired data in three case studies. This novel technique is particularly applicable to the evaluation and prediction of MIP receptor specificity and efficiency in complex aqueous systems.
