Evaluation of Freshness of Soft Tissue Samples with Optical Coherence Tomography Assisted by Low Frequency Electric Field

We present an optical coherence tomography based methodology to determine freshness of soft tissue samples by evaluation of their interaction with low frequency electric field. Various biological tissues samples of different stages of freshness were exposed by low frequency electric current. The influence of the low frequency electric field on tissues was observed and quantified by the double correlation optical coherence tomography (dcOCT) approach developed in house. The quantitative evaluation of electric field — tissue interaction by dcOCT shows an increase of its relative magnitude with the tissue freshness from fresh to the non-fresh ones. The presented approach has a strong potential in food sciences for evaluation of meat quality.
