以10个品种(系)宁夏枸杞鲜果为材料,测定枸杞鲜果的百粒重、最大单果重、硬度、色差、可溶性固形物、可滴定酸、总糖、黄酮等19项理化指标,采用模糊感官评价法,调查50名男性、50名女性对枸杞鲜果色泽、外观、苦味、口感4个指标评分,分析枸杞鲜果理化指标与感官评价相关性。结果表明,10个品种(系)枸杞鲜果总糖含量最高的“14-401”与其它品系差异显著;可滴定酸含量最高的“14-401”与其它品系差异显著;果实硬度较大的“Z44”和“14-4-4-13”与其它品系差异显著。10个品种(系)枸杞鲜果色泽平均得分在3.30~7.43之间,外观平均得分在3.15~7.18之间,苦味平均得分在4.20~7.85之间,口感平均得分在4.06~8.78之间;“14-4-4-13”色泽、外观、口感评分均最高,苦味评分最低。最大单果重和男性色泽评价、男性外观评价、综合外观评价均显著正相关,与女性苦味评价显著负相关;硬度与男性口感评价显著负相关;糖酸比与女性苦味评价显著正相关;色泽评价与外观、口感评价极显著正相关;苦味评价与外观、色泽评价显著负相关,与口感评价极显著负相关;外观评价与口感评价极显著正相关。 相似文献

Lactobacillus bulgaricus was used to ferment raw pork to pork jerky at different fermentation conditions, including temperature, initial pH value, and time. Through assessing the sensory attributes, the free amino acids, and pH of the pork jerky, it was determined that the optimum conditions for fermentation was temperature of 35 °C, initial pH of 6.5, and fermentation time of 36 hr. Through fermenting with L. bulgaricus, the texture, the color, and the flavor of the prepared pork jerky were improved. The pH of pork jerky was lower than fresh pork which thus, potentially enhanced the safety of pork jerky. Additionally, the free amino acids contents of pork jerky were higher (greater than 143.5 mg/100 g) than the fresh pork (64.0 mg/100 g) which suggest more benefits and better absorption. The results presented herein demonstrate that the L. bulgaricus can be used for the production of fermented pork jerky to improve the quality attributes and the safety of pork jerky.
