Abstract

The aim of the study was to investigate the possible use of mussels and algae wastes processed into high quality and safe food additives for the poultry. Black sea mussels (Mytilus galloprovincialis Lamarck) and algae (phyllophora) were used as a waste product. The samples were taken from the households where mussels were initially processed at an agar plant. Waste samples and derived additives were tested for bacterial load, quality and chemical composition. In addition, proteinmineral and mineral additive were produced from waste products. Their possible uses in poultry meat production were investigated. It was found that contamination with mesophilic bacteria and facultative anaerobic organisms fluctuates within current requirements. Sometimes even substantially exceeds them depending on waste storage conditions. The contamination with E. coli, Salmonella, and other pathogenic microorganisms is also observed within existing requirements or exceeding them. Chemical analysis reveal that intact mussels consist of average 80% wet matter and 20% dry matter, 9.4% protein, 1.2 % fat, 4.8 % nitrogen free extractive substances, 0.18% ash, 24.5 g/kg calcium, 1.0 g/kg phosphorus, 0.18 g/kg potassium. On the other hand, mussel valves consist of % 12 wet matters and % 88 dry matters, 37.2g/kg calcium, 0.2 g/kg phosphorus, 0.1 g/kg potassium. Use of additives in poultry production positively affects development and slaughter-out percentage and does not reduce the quality and biological value of their meat. As a conclusion it can be said that non-waste product from processed mussels represent a kind of raw material which can be used as food additive in animal industry after being technologically processed.
非废物水生物管理
本研究的目的是探讨将贻贝和藻类废物加工成高质量和安全的家禽食品添加剂的可能性。黑海贻贝(Mytilus galloprovincialis Lamarck)和藻类(phyllophora)被用作废物。样本取自最初在琼脂厂处理贻贝的家庭。对废物样品和衍生添加剂进行细菌负荷、质量和化学成分测试。此外,还利用废渣生产矿物蛋白和矿物添加剂。研究了它们在禽肉生产中的可能用途。发现中温细菌和兼性厌氧生物的污染在当前要求范围内波动。有时甚至大大超过,取决于废物储存条件。大肠杆菌、沙门氏菌和其他病原微生物的污染也符合或超过了现有的要求。化学分析表明,完整贻贝的平均湿物质含量为80%,干物质含量为20%,蛋白质含量为9.4%,脂肪含量为1.2%,无氮萃取物含量为4.8%,灰分含量为0.18%,钙含量为24.5 g/kg,磷含量为1.0 g/kg,钾含量为0.18 g/kg。另一方面,贻贝瓣的湿物质含量为% 12,干物质含量为% 88,钙含量为37.2g/kg,磷含量为0.2 g/kg,钾含量为0.1 g/kg。在家禽生产中使用添加剂会对发育和屠宰率产生积极影响,并且不会降低肉类的质量和生物价值。综上所述,贻贝加工后的非废弃物是一种经过技术加工后可作为动物工业食品添加剂的原料。
