“…The most abundant proteins in milk are casein (α s1 -casein, α s2 -casein, β s1 -casein, and κ-casein), α-lactoalbumin, and β-lactoglobuline. Although some of these proteins contribute to the presence of small amounts of CYS in milk, it is in its oxidized form, namely, cystine (C 6 H 12 N 2 O 4 S 2 ), which does not trigger a reaction with PTSO. , The amount of PTSO could also be affected by the presence of GSH (a tripeptide with antioxidant properties that contain CYS), which is found in cellular tissues, but it is expected that PTSO will not react with GSH because it is converted in oxidized glutathione by the reaction with glutathione peroxidase. , This is an important aspect to be taken into account when considering this molecule as a marker for OE residues in milk. Regardless of this issue, the absence of derivative compounds from PTSO (CSSP and GSSP) in milk was tested by applying a previously proposed UHPLC–MS/MS method .…”

Onion extract is used as a feed supplement for the diet of dairy cows, acting as inhibitor of methane production; however, its properties could alter sensory attributes of milk. In this work, we propose a method to evaluate the influence of this extract on milk properties, using propyl propane thiosulfonate (PTSO) as a marker. PTSO is extracted using a quick, easy, cheap, effective, rugged, and safe procedure and monitored by high-performance liquid chromatography with ultraviolet detection. The method was applied to milk samples obtained from 100 dairy cows fed during 2 months with enriched feed. In addition, a milk tasting panel was established to evaluate the PTSO residue that should not be exceeded to guarantee milk sensory attributes. It was established that a value of PTSO lower than 2 mg kg does not alter milk organoleptic properties. This fact makes onion extract an interesting alternative as a feed supplement to control the methane emissions without any influence on milk attributes.

“…Some well-known dairy products, however, are exported to many countries. Consumer milk, fresh milk, yogurt, cream, cream products, and butter are the most common dairy products mentioned by (Belitz et al, 2008, p. Dairy farming is considered one of the most ancient industries of humankind. According to researchers, goats were the first domesticated mammal used for milk production around 10,000 to 11,000 years ago, followed by cattle around 9,000 years ago (Hirst, 2019).…”

Farmers in rural Bangladesh have been involved in the dairy industry since the 17th century. It is widely regarded as a means ofsubsistence. Milk is used in nutrition, cottage industries, and industrial dairy processing. PRAN Dairy Limited (PDL) in Bangladeshworks with rural dairy farmers under a contractual partnership to secure daily milk supplies. This study discusses PDL's relationshipwith rural dairy farmers through the lens of Agency Theory. In four districts of Northern Bangladesh, 45 farmers were selected andinterviewed; PDL has worked with them for at least ten years. This study employs the qualitative method with NVIVO12 to analyzethe interview transcripts thematically. A new version of the agency contract in the dairy industry was created by categorizing the existingone using a set of 15 codes based on five themes (risk, motivation, skills, penalties, and efforts). The study concluded that theimplications of Agency Theory in the dairy industry from Bangladesh's perspective paved the way for multidisciplinary approaches touncover more research opportunities in this sector, such as farmers' intentions to join the agency relationship with PDL.

Whey - Biological Properties and Alternative Uses

Whey production can be an economic and environmental problem for small creameries and acid whey producers. The fermentation and distillation of whey not only eliminates the cost of disposing whey as waste while minimizing environmental impact but adds a revenue option through production of a value-added product. Kluyveromyces marxianus is typically utilized to ferment the pasteurized and pretreated whey. The fermented product contains approximately 3% ethanol v/v. Various options for distilling may be utilized such as a simple two-pot system or a more complex four-stage system to assure production of a neutral spirit. Quality of the distilled spirit is impacted by whey source, whey pretreatment, fermentation conditions, and the distilling process.
