This study investigated the effects

This study investigated the effects of using medium voltage (~300 V) electrical stimulation (ES) and ageing on alpaca meat. A total of 50 huacaya alpacas were distributed across three age groups (18, 24 and 36 months) and two genders (females and castrated males). At 24 h post mortem the m. longissimus thoracis et lumborum (LL) and m. semimembranosus (SM) muscles were removed and aged for either 5 or 10 days. In comparison to non-ES samples, ES significantly reduced: LL purge values by 3.0% and LL shear force (SF) at 5 and 10 days (by 21.6 N and ageing further reduced tenderness by 6.6 N), and SM SF by 5.8 N with significant age effects observed in both ES and non-ES SM samples, such that SF increased by 0.53 N with each month increase in animal age. Consumers rated ES samples higher on tenderness, juiciness, flavour and overall rating. ES and ageing of alpaca carcasses are recommended.

Hierdie studie ondersoek die gevolge van die gebruik van medium spanning (~ 300 V) elektriese stimulasie (ES) en veroudering op alpaca vleis. 'N Totaal van 50 huacaya alpakkas is versprei oor drie ouderdomsgroepe (18, 24 en 36 maande) en twee geslagte (vroue en gekastreer mans). Op 24 h nadoodse die m. longissimus thoracis et lumborum (LL) en m. semimembranosus (SM) spiere verwyder en vir minstens 5 tot 10 dae tussen die ouderdomme. In vergelyking met nie-ES monsters, ES aansienlik verminder: LL purge waardes deur 3,0% en LL skuifkrag (SF) by 5 en 10 dae (deur 21,6 N en veroudering verder verminder sagtheid met 6,6 N), en SM SF met 5,8 N. met 'n beduidende ouderdom effekte waargeneem in beide ES en nie-ES SM monsters, sodanig dat SF het met 0,53 N elke toename maand in dier ouderdom. Verbruikers gegradeer ES monsters hoër op sagtheid, sappigheid, smaak en algehele gradering. ES en veroudering van alpaca karkasse word aanbeveel.
