This review aims to evaluate the prebiotic potential of vegetable flours in the manufacture of dairy products and their effects on technological and sensory properties. Overall, studies have shown positive results, not only with regard to the growth of the lactic and/or probiotic bacteria but also for sensory acceptance, rheological and physicochemical properties. In addition, integrated studies focusing on the development of dairy functional foods must be conducted in order to optimise the amount of flour to be added in each dairy food formulation and also to assess the impact of prebiotic flour addition on the intrinsic quality parameters of the dairy products.

In this study, Flavourzyme was encapsulated in liposomes to accelerate the ripening of Iranian white cheese. Liposomal enzyme was prepared using a modified heating method. The influence of enzyme content, ripening time and curd retention in saturated brine on proteolysis indices and sensory perception was investigated using response surface methodology. The most influential factor on proteolysis indices was ripening time, while the content of liposomal enzyme and retention time were also significant (P < 0.05). The maximum proteolysis indices and highest sensory characteristic scores were achieved by applying 0.3% w/w enzyme, ripening for 30 days and 8-h curd retention in saturated brine.

Among microencapsulation techniques used in food production, nanoliposomes are known to be one of the most interesting methods for the encapsulation of flavours, essential oils, amino acids, vitamins, minerals, enzymes, micro-organisms, redox agents, colourants, antioxidants and antimicrobials. Research has also been conducted on possible applications of nanoliposomes in cheese production by the encapsulation of ferrous glycinate, ferrous sulphate, antioxidants, nisin, β-galactosidase and cheese-ripening enzymes. In this article, nanoliposome application in cheese production has been reviewed under three main themes, namely (i) acceleration of cheese ripening, (ii) fortification of cheese with vitamins and minerals and (iii) increasing shelf life of cheese products. Various aspects of nanoliposome application in cheese technology including currently available preparation methods, efficiency of nanoliposomal enzymes, their effects on the acceleration of cheese ripening as well as rheological and chemical properties of the cheese curd are discussed.

A dairy beverage containing propionic acid was produced using the adjunct starter cultures with Lactobacillus acidophilus and Propionibacterium freudenreichii ssp. shermanii. The impacts of temperature (30, 35 and 40 °C) and inoculation ratio (1:2, 1:4 and 1:8) on propionic acid production and viability of micro-organisms were studied. The incubation temperature had a significant adverse ( P < 0.05) effect on the viability of P. freudenreichii and propionic acid production. Maximum amount of produced propionic acid (in 1:4-30 °C treatment) was 0.77%w/w. P. freudenreichii and L. acidophilus counts remained high (9 × 106 and 1.5 × 106 cfu/ mL, respectively) after cold storage. [ABSTRACT FROM AUTHOR]
