Lipid oxidative changes in chitosan-oregano coated traditional dry fermented sausage Petrovská klobása

The effect of a chitosan coating with added essential oil of oregano (Origanum vulgare) on lipid oxidation of dry fermented sausage (Petrovská klobása) was investigated. Fatty acid profile, aldehyde contents and sensory analysis of odor and flavor were determined after drying and during seven months of storage.     

Effect of plant polyphenols and ascorbic acid on lipid oxidation,residual nitrite and N‐nitrosamines formation in dry‐cured sausage

The effects of green tea,grape seed polyphenols and ascorbic acid on pH, water activity (a_w), microbiological counts, TBARS, residual nitrite and N‐nitrosamines were determined in dry‐cured sausages during the ripening period. Results showed that TBARS increased gradually during ripening (P < 0.05), but were significantly reduced with plant polyphenols and ascorbic acid (P < 0.05). Green tea polyphenol (GTP) was most effective (P < 0.05) in reducing TBARS. Plant polyphenols and ascorbic acid significantly decreased residual nitrite, ascorbic acid being most effective (P < 0.05). The amount of N‐nitrosamines increased during ripening, but was significantly reduced with plant polyphenols and ascorbic acid (P < 0.05). Plant polyphenols had no significant effects on moisture content, a_w, pH or microbiological counts in dry‐cured sausage during ripening (P > 0.05). It was concluded that plant polyphenols and ascorbic acid were effective in maintaining the quality and safety of dry‐cured sausages.     

Reduction of Drying Time for Pepperoni by Vacuum-drying

Commercial pepperoni was dried under vacuum (100 kPa) at three temperatures (177°, 19°, and 22°C) and matching controls were dried under commercial conditions. Vacuum-dried pepperoni achieved a moisture: protein (M:P) ratio of 1.6:1 after 9 to 12 days drying, compared to 18 days for the control. Overall drying time was reduced ～30%. Among temperature treatments, 17°C treatment had more weight loss and darker color (P < 0.05) than others. Weight loss and Kramer shear force were higher (P < 0.05) for vacuum-dried pepperoni, whereas Hunter a and b values tended to be higher for the control throughout the drying period.

笋干菜糯米营养保健香肠的开发研究

研究了笋干菜营养香肠的生产工艺,探讨了影响其质量的因素:笋干菜的添加量、糯米的添加量、糯米的颗粒度及肥、瘦肉的比例。并在此基础上采用正交实验得出了最佳工艺条件和配比,结果表明:五花猪肉79%,糯米用量15%,笋干菜用量6%,肥、瘦肉比例2:8,糯米颗粒度30目时香肠质量最佳。     

Freeze/thaw Stability of Cooked Pork Sausages as Affected by Salt, Phosphate, pH, and Carrageenan

The effects of κ, ι, or λ carrageenan (CGN), sodium tripolyphosphate (STPP), chloride salts, and meat pH on the freeze/thaw stability of cooked pork sausages were investigated. STPP decreased thaw drip (TD) and increased hardness for all treatments regardless of type of salt or CGN. KCI did not affect the texture of control samples in the presence of STPP, but decreased the functionality of κ- and ι-CGN. Increased meat pH increased the hardness and decreased thaw drip for all CGN treatments, except for λ-CGN, which remained unchanged. k- and ι- CGN increased moisture retention of sausages prepared from low-pH meat.     

发酵香肠中葡萄球菌快速"两步一补"鉴定

介绍一种凝固酶阴性葡萄球菌(CNS)快速鉴定方法:"两步一补法"。并用此方法鉴定传统发酵香肠中CNS的分布情况。CNS菌株先经二步鉴定:第一步4h,包括:蕈糖、尿素酶、碱性磷酸酶;第二步24h,包括:鸟氨酸脱羧酶、新生霉素敏感性、磷霉素敏感性、厌氧生长。极少数不能鉴定的CNS菌株,用补充试验完成结果。能鉴定出发酵香肠中CNS的22个种及2个亚种,本文两步法能鉴定出发酵香肠中64%以上常见CNS菌种,仅36%的菌株需用补充实验证实。     

Potassium Lactate and Fresh-Pork-Sausage Formulation Effects on Shelf Life in Lighted and Unlighted Display

ABSTRACT:  The objective was to examine the effects of potassium lactate (KL) and raw-meat blend on the shelf-life of fresh-pork-sausage patties in lighted and unlighted display. Four fresh-pork-sausage blends (70% prerigor meat, 30% fresh-pork trim; 80%/20%; 90%/10%; and 100%/0%) were formulated ( n = 3) with 0% and 3% KL, and patties were displayed for 10 d at 4 °C in lighted display or for 7 d in unlighted display followed by 3 d in lighted display. Patties with KL had lower aerobic plate counts (APC), more stable color (greater a* and chroma, less visual discoloration), and less lipid oxidation ( P < 0.05) during display than did patties without KL. Patties in the light for 10 d were more discolored and had more lipid oxidation ( P < 0.05) than those in the dark for 7 d followed by the light for 3 d. Patties with KL in the light for 10 d had similar color ( P > 0.05) to patties without KL that were in the dark for the first 7 d. Adding KL resulted in similar color stability ( P > 0.05) among patties made from 80, 90, and 100% prerigor meat and greater color stability ( P < 0.05) than similarly formulated patties without KL. By using 3% KL, fresh-pork-sausage patty color stability was maximized, APC and lipid oxidation were minimized, and formulation costs can be decreased by using less-expensive fresh-pork trim for up to 20% of the blend. Adding KL also minimized the effects of display lighting on myoglobin and lipid oxidation.
