Abstract

Bioconservation extends the useful life of food and improves its quality. This paper aimed to determine the effect of the supernatant of Lactobacillus plantarum and Lactobacillus lactis on pork loin. The supernatant (500 μl) was used in 50 g of loin, and as controls, lactic acid (2%) and physiological saline (without additive). Each treatment was evaluated at 4 and 20 °C for 15 days. On days 0, 7 and 15, microbiological, physicalchemical and sensorial measurements were performed; the first two were evaluated with a 4×2 factorial block design. The block consisted of measurement days, and the factors were additive and temperature. Sensory evaluation was done by analysis of variance. There was no interaction between factors (p > 0.05). Total coliforms, sulfite-reducing clostridium , and pH showed no difference in the additive factor (p > 0.05), but fecal coliforms, acidity and water retention capacity did (p < 0.05). Refrigeration (4 °C) had better results. It is concluded that the supernatant of L. plantarum preserves pork loin; in addition, it maintains organoleptic characteristics and avoids microbial growth. L. lactis showed similar results to lactic acid and was better than the treatment without additive, although the values of this strain were inferior to those found in L. plantarum .

生物保存延长了食品的使用寿命，提高了食品的质量。本文旨在研究植物乳杆菌和乳酸乳杆菌上清液对猪里脊肉的影响。取50 g腰肉取上清(500 μl)，以乳酸(2%)和生理盐水(不加添加剂)为对照。每次处理在4°C和20°C下进行15天的评估。在第0、7和15天，进行微生物、物理化学和感官测量;前两个用4×2因子块设计进行评估。块由测量天数组成，影响因素为添加剂和温度。通过方差分析进行感官评价。各因素间无交互作用(p > 0.05)。总大肠菌群、亚硫酸盐还原梭菌和pH对加性因子无显著影响(p > 0.05)，而粪大肠菌群、酸度和保水能力对加性因子有显著影响(p < 0.05)。冷藏(4°C)效果更好。综上所述，植物乳杆菌上清液保存猪里脊肉;此外，它保持了感官特性，避免了微生物的生长。乳酸菌的结果与乳酸相似，且优于不添加添加剂的处理，但该菌株的值不如植物乳杆菌。

期刊介绍： The Revue de Médecine Vétérinaire publishes four kinds of text: 1) Scientific reviews on subjects related to veterinary and comparative medicine. Suggested length: 10 to 30 typed pages. 2) Original reports on fundamental or applied research. Suggested length: 10 to 15 typed pages. 3) Continuous education articles, that should be easily understandable by non-specialists. Suggested length: 10 to 15 typed pages. 4) Clinical reports. Suggested length: 5 to 15 typed pages. The publication can be done in French language or English language. For an article written in English by not english native speakers authors, the manuscript must be subjected by attesting that it was read again by an anglophone scientist or a scientific translator. The authors must certify that the manuscript was not published or subjected for publication to another review. The manuscript must be accompanied by a sheet signed by all the joint authors indicating their agreement for the tender of the manuscript. The publication is free but a financial participation could be required for the photographs color. An estimate will be sent to collect the agreement of the authors.
