Abstract
This study aimed to evaluate the compatibility of L. acidophilus KLDS 1.0738 (LA-1.0738) with different prebiotic carbohydrates to develop a synbiotic soft soy cheese. It was observed that the addition of 4% (m/v) prebiotics mixture (galacto-oligosaccharide:inulin = 1:3) to soy cheese significantly improved the growth of LA-1.0738, making it no less than 8.2 log colony-forming unit (CFU)/g during the 28-day storage period, but had limited influence on the viability of S. thermophilus KLDS T1C2 (STT1C2). Meanwhile, because of the presence of prebiotics, soy cheese fermented by LA-1.0738 in co-culture with STT1C2 exhibited higher values of acidity, proteolysis and lipolysis index as well as better texture properties and sensory acceptance. These results suggested that the selected combination of prebiotics could be used as functional ingredients to manufacture soy cheese to maintain the survival of desired LA-1.0738, which contributed to improve the texture and sensory features of soy cheese.
期刊介绍:
''Quality Assurance and Safety of Crops & Foods'' is an international peer-reviewed journal publishing research and review papers associated with the quality and safety of food and food sources including cereals, grains, oilseeds, fruits, root crops and animal sources. It targets both primary materials and their conversion to human foods. There is a strong focus on the development and application of new analytical tools and their potential for quality assessment, assurance, control and safety. The scope includes issues of risk assessment, traceability, authenticity, food security and socio-economic impacts. Manuscripts presenting novel data and information that are likely to significantly contribute to scientific knowledge in areas of food quality and safety will be considered.
''Quality Assurance and Safety of Crops & Foods'' provides a forum for all those working in the specialist field of food quality and safety to report on the progress and outcomes of their research.
