Summary of "The effect of whole carcase medium voltage electrical stimulation, tenderstretching and longissimus infusion with actinidin on alpaca meat quality."

The effect on alpaca meat quality from applying medium voltage electrical stimulation (ES) in combination with tenderstretching (TS; pubic symphysis suspended) to whole carcases was investigated, along with the effect of actinidin infusion on alpaca longissimus (LTL) quality. Carcases (n = 36) were allocated to either no ES + achilles hung; or ES + TS. The left- and right-hand side LTL of each carcase was allocated to one of three infusion treatments; no infusion (control), infusion with water or infusion with enzyme. Processing treatments reduced LTL and semimembranosus shear force without negatively impacting colour or oxidation traits. Infusion with enzyme reduced LTL shear force relative to control and water treatments but resulted in reduced consumer acceptance. The use of TS with ES in commercial alpaca processing is supported. There was no advantage to infusing alpaca LTL with actinidin as results indicate a net negative effect on consumer acceptance of this novel meat.

Medical and Biotech [MESH] Definitions

The electrical response evoked in a muscle or motor nerve by electrical or magnetic stimulation. Common methods of stimulation are by transcranial electrical and TRANSCRANIAL MAGNETIC STIMULATION. It is often used for monitoring during neurosurgery.

Optical imaging techniques used for recording patterns of electrical activity in tissues by monitoring transmembrane potentials via FLUORESCENCE imaging with voltage-sensitive fluorescent dyes.

The voltage differences across a membrane. For cellular membranes they are computed by subtracting the voltage measured outside the membrane from the voltage measured inside the membrane. They result from differences of inside versus outside concentration of potassium, sodium, chloride, and other ions across cells' or ORGANELLES membranes. For excitable cells, the resting membrane potentials range between -30 and -100 millivolts. Physical, chemical, or electrical stimuli can make a membrane potential more negative (hyperpolarization), or less negative (depolarization).

An angiopoietin that is closely related to ANGIOPOIETIN-1. It binds to the TIE-2 RECEPTOR without receptor stimulation and antagonizes the effect of ANGIOPOIETIN-1. However its antagonistic effect may be limited to cell receptors that occur within the vasculature. Angiopoietin-2 may therefore play a role in down-regulation of BLOOD VESSEL branching and sprouting.

Diagnosis of disease states by recording the spontaneous electrical activity of tissues or organs or by the response to stimulation of electrically excitable tissue.
