background: lactoperoxidase (lpo) is one of the most heat-stable enzymes in milk and its inactivation has been proposed for monitoring thermal processes. the aim of this study was to provide information on activity and thermal inactivation behavior of lpo in iranian cow and buffalo milk and whey. methods: sixty cow and buffalo milk samples were collected. the lpo activity was measured using spe...

a neuro-fuzzy modeling tool (anfis) has been used to dynamically model cross flow ultrafiltration of milk. it aims to predict permeate flux and total hydraulic resistance as a function of transmembrane pressure, ph, temperature, fat, molecular weight cut off, and processing time. dynamic modeling of ultrafiltration performance of colloidal systems (such as milk) is very important for designing ...

Heat-resistant microorganisms such as Bacillus subtilis spores derived from soil may exist in soybean milk and can reduce the shelf life of tofu produced from conventional processing of soybean milk. Conventional high-temperature, long-time heat processing of soybean milk sufficiently inactivates spores of this organism. An apparatus to pasteurize soybean milk using radio-frequency flash heatin...

The nutritional, physicochemical, and functional properties of milk are affected by thermal processing. Buffalo make a substantial contribution to global production but there have been comparatively few studies on how processing affects the buffalo milk. This paper critically reviews current knowledge regarding changes during storage milk, milk-based products, buffalo-bovine blends. Heating res...

MicroRNAs (miRs, miRNAs) play central roles in gene regulation. Previously, we reported that miRNAs from pasteurized, store-bought bovine milk have biological activity in humans. Here we assessed the effects of milk processing, storage, somatic cell content, and handling by consumers on the degradation of miRNAs in milk; we also quantified miRNAs in dairy products. Pasteurization and homogeniza...

this experiment was conducted to evaluate the effects of processing protein meals by tannin extracted from pistachio by-product on apparent total tract digestibility, ruminal fermentation and performance of dairy cows. for tannin extraction, one kilogram of sun-dried pistachio by-products was immersed in four liters of water for 48 h. then, pistachio by-products were removed from the water and ...

determination of milk yield potential using an accurate method is essential for assessing nutritional requirements, evaluation of genetic potential, lamb growth and survival, management decisions and improving performance traits of sheep flocks. exogenous oxytocin injection is applied to estimate milk secretion rate in sheep. oxytocin is a neurohormone produced in the hypothalamo-neurohypophysi...

Product value chain is the full range of activities including production, processing, marketing and distribution a product takes until it gets to the consumer. In the dairy world, milk is a very vital food commodity for the growth and development of individuals; it’s a good source of calcium, vitamin B2, vitamin C and D and amino acids. Milk however, goes through a number of very important step...
