A geographically-registered Arapgir purple basil pesto sauce prepared with four different cheese varieties: Comparison of physical, bioactive and rheological properties

The demand for pesto sauces with different properties (such as color, taste, flavor) has increased recently. This study aimed to investigate the effects of geographically-registered Arapgir purple basil pesto sauce prepared with four different cheese varieties (Beyaz, Tulum, fresh- and aged-Kashar) on physical, rheological characterization and sensory properties. Pesto sauces had an acidic score according to chemical and sensory characterization. Pesto sauce with Tulum cheese exhibited higher bioactivity (total phenolic contents and antioxidant activities) than other sauces (PG″. The Herschel Bulkley model fitted the flow experimental data well (R2>0.9991). All of the pesto sauces prepared with different cheese varieties were appreciated at high levels in sensory evaluation by the panelists

Changes in volatile composition, proteolysis and textural and sensory properties of white-brined cheese: effects of ripening temperature and adjunct culture

International audienceThe effects of ripening temperature and adjunct cultures (Lactobacillus helveticus and Lactobacillus casei) on the volatile compounds and sensory and textural properties of white-brined cheese were investigated. Three batches of cheese were produced: cheese A was inoculated with only cheese starter culture (Lactococcus lactis subsp. lactis plus Lactococcus lactis subsp. cremoris), cheese B was inoculated with cheese starter culture plus Lactobacillus helveticus and cheese C was inoculated with cheese starter culture plus Lactobacillus casei. Cheeses were ripened at 6 or 12 °C and analyzed at 30-day intervals up to 120 days of ripening. The use of adjunct culture and ripening temperature significantly influenced the pH and proteolysis of cheeses (P < 0.05). Acids, ketones and alcohols were found at high levels in all three cheeses. Volatiles were significantly influenced by the use of the adjunct cultures, ageing and to some extent ripening temperature (P < 0.05). Textural parameters of the cheeses were significantly affected by the adjunct culture during ripening (P < 0.05). The sensory scores of the cheese samples decreased during the ripening period. An age-related bitterness was detected by the panellists in 90 or 120-day-old cheeses with added adjunct cultures. In conclusion, the use of adjunct culture and ripening at 12 °C enhanced the volatile composition and changed the texture profiles of the cheeses
