Forty-two New Zealand White rabbits ( = 21/group) were fed with two different diets: a commercial diet (control group) and a diet supplemented with goji berries (3% /). After slaughtering, the effect of dietary supplementation on microbiological, physico-chemical, and sensory characteristics of the rabbit loins, packed in an oxygen-permeable package, was evaluated at 6 h post mortem (day 0), after 4 and 10 days of refrigerated storage. No relevant results were obtained for pH and total volatile basic Nitrogen (TVBN) values but with regards to the color, some significant differences were observed between the groups. The goji berries (GBs) dietary supplementation had positive effects by reducing thiobarbituric acid reactive substances (TBARS) values in all the observations ( < 0.001). Moreover, microbiological results showed that the supplementation had a significant impact on spp. ( < 0.001) prevalence, indeed the goji group had higher means on day 0 ( < 0.05) and on day 4 ( < 0.001) than the control group. Lastly, with regards to the consumer's test, the tasters assigned a higher score to GBs rabbit meatballs and the purchase interest increased when the rabbit diet was known. Overall, these results indicate that the goji berries inclusion in the rabbit diet could represent a valuable strategy to improve quality and sensory traits of meat.
42只新西兰白兔(每组21只)被喂食两种不同的日粮:一种商业日粮(对照组)和一种添加枸杞的日粮(3%)。屠宰后,在宰后6小时(第0天)、冷藏储存4天和10天后,评估日粮添加对包装在透气包装中的兔腰肉的微生物、理化和感官特性的影响。pH值和总挥发性碱性氮(TVBN)值未获得相关结果,但在颜色方面,两组间观察到一些显著差异。在所有观察中,枸杞日粮添加通过降低硫代巴比妥酸反应性物质(TBARS)值产生了积极影响(P<0.001)。此外,微生物学结果表明,添加对肠杆菌科细菌的患病率有显著影响(P<0.001),实际上,枸杞组在第0天(P<0.05)和第4天(P<0.001)的平均值高于对照组。最后,关于消费者测试,品尝者给枸杞兔肉丸子的评分更高,并且当知道兔子的日粮时购买兴趣增加。总体而言,这些结果表明,在兔子日粮中添加枸杞可能是提高兔肉品质和感官特性的一种有价值的策略。
