The appearance of a food product is one of the first things that impacts a consumer’s opinion of overall quality; food manufacturers therefore seek to ensure their product is ideal and the same at each time of production. Instrumental tests are com

In the food industry, a reactive, siloed approach to food safety is common; the proactive application of a broad risk management (multi-faceted risk management) approach is in a relatively early stage of evolution. This paper shows that opportunities

Heat treatment of milk to extend its shelf life by reducing the potential of microorganisms and enzymes to make the product unsafe or spoil has consequences on its organoleptic qualities. The greater the heat load, the greater are the consequences; t

Human sensory analysis is often simplistically and erroneously labelled “subjective”; this is then used to justify the attempted application of a range of instrumental methods to achieve the same purported measurement end points. However, there a

This study explored the microbiota of Formaella, Kopanisti, Feta and Mana cheeses. A total of 133 wild lactic acid bacteria were isolated and classified phenotypically. Mesophilic lactobacilli were the most abundant group. Thermophilic lactobacilli a

The enzymes of starter and non-starter lactic acid bacteria deliver flavour generation in fermented dairy products, especially cheese. The control of flavour development in New Zealand cheese has been underpinned by the development of the modern star

Seven Bacillus strains isolated from milk powder production lines were grown in two selective media. All the strains produced extracellular and intracellular proteinase and lipase activity, but at different levels. Proteolytic activity was generally

Freshly drawn milk contains indigenous enzymes, including proteases and lipases. During handling and processing, milk acquires contaminating bacteria that produce further proteases and lipases, adding to the enzyme loading in the milk. Even when seve

Most fast-milk-coagulating Lactococcus lactis starter strains contain a plasmid-encoded cell envelope proteinase (lactocepin; EC 3.4.21.96) having PI-type (lactocepin I) or PI/III intermediate-type (lactocepin I/III) specificity (those with PIII-type

Oligopeptidases of starter and nonstarter lactic acid bacteria contribute to the proteolytic events important in maturation and flavor development processes in cheese. This paper describes the molecular cloning, expression, and specificity of the oli
