| During enzymatic process of cheese manufacturing, rennin cleaves κ-casein releasing two fractions: para-κ-casein and glycomacropeptide (GMP), which remains soluble in milk whey. GMP is a peptide with structural particularities such as chain carbohydrates linked to specific threonine residues, to which a great variety of biological activities is attributed. Worldwide cheese production has increased generating high volumes of milk whey that could be efficiently used as an alternative source of high quality peptide or protein in foodstuff formulations. In order to evaluate isolation and recovery on whey GMP by means of thermal treatment (90 °C), 18 samples (2 L each) of sweet whey, resuspended commercial whey (positive control) and acid whey (negative... |

| Abstract Fermented dairy beverages added with red rice extract and whey were the developed, physicochemical and microbiological properties were evaluated. A central composite rotatable design was applied, using nine treatments with three replicates. The pH indicated that the beverages could be consumed without the addition of preservative for up to 28 days of storage. The beverages are characterized as partially skimmed, with high protein content, zinc, manganese and copper levels, similar potassium and iron levels and low sodium, magnesium and calcium levels, if compared to the recommended daily index. The absence of pathogens and numbers of viable lactic acid bacteria above the established minimum level were observed. The physicochemical parameters were... |

| ABSTRACT: This paper aim to evaluate the ultrafiltration (UF) process for constituents recovery from whey. Sequences of factorial designs were performed by varying temperature (5 to 40°C) and pressure (1 to 3 bar), to maximize the proteins concentration using membrane of 100kDa in dead end system. Based on the best result new experiments were performed with membrane of 50kDa and 10kDa. With the membrane of 50 the protein retention was about 3 times higher than the membrane of 100kDa. The concentrated obtained by UF membrane of 10kDa, 10°C and 2 bar in laboratory scale showed a mean protein retention of 80 %, greater protein solubility, emulsion stability and the identification of β-lactoglobulins (18.3 kDa) and α-lactalbumin fractions (14.2kDa). Therefore,... |

| ABSTRACT: Whey is a by-product of the dairy industry of great importance due to its high nutritional value, and can be used for the manufacture of fermented dairy drinks which, combined with fruit, increase the nutritional value and add characteristic flavors. Therefore, a fermented dairy beverage with caja-mango pulp (Spondias dulcis) was elaborated and its nutritional information as well as the physical-chemical stability were evaluated during storage. The results showed that the nutritional information met the requirements stipulated by the Brazilian legislation. The physical-chemical stability of the dairy fermented drink in terms of pH, acidity, syneresis and sedimentation was influenced by the storage time, possibly associated with uncontrolled... |

| ABSTRACT: This study aimed to develop and characterize beverages formulated with whey protein and added lutein. Beverages formulated with 0.5 (F1), 2.0 (F2), 4.0 (F3) and 6.0% w/v (F4) whey protein were physicochemically and microbiologically characterized, and sensory evaluated. The physicochemical analyses indicated that the protein content significantly changed (P<0.05) the acidity values, soluble solids and the colorimetric coordinates, making possible to adjust mathematical models for all these variables. Microbiological analyses showed no significant contamination (P<0.05) during processing that would compromise drinks quality of the drinks. Carotenoid content and the antioxidant activity did not change significantly (p>0.05) with increased... |

| Whey is a co-product of processes for the production of cheese and casein that retains most of the lactose content in milk. World production of whey is estimated around 200 million tons per year with an increase rate of about 2%/per year. Milk production is seasonal, so surplus whey is unavoidable. Traditionally, whey producers have considered it as a nuisance and strategies of whey handling have been mostly oriented to their more convenient disposal. This vision has been steadily evolving because of the upgrading potential of whey major components (lactose and whey proteins), but also because of more stringent regulations of waste disposal. Only the big cheese manufacturing companies are in the position of implementing technologies for their recovery and... |
