Non-thermal processing methods, such as pulsed electric field (PEF) and tangential-flow microfiltration (TFMF), are emerging processing technologies that can minimize the deleterious effects of high temperature short time (HTST) pasteurization on quality attributes of skim milk. The present study investigates the impact of PEF and TFMF, alone or in combination, on color and volatile compounds i...

Background & Objectives: Direct addition of antimicrobial materials to food during food processing is an effective method for controlling microbial contaminants of food and extending the shelf-life of food products. Objective of this research was to study the antimicrobial effect of zinc oxide (ZnO) nanoparticle and potential applications of ZnO nanoparticles in terms of controling two...

1MicroRNAs (miRs, miRNAs) play central roles in gene regulation. Previously, we2reported that miRNAs from pasteurized, store-bought bovine milk have biological3activity in humans. Here we assessed the effects of milk processing, storage, somatic cell4content, and handling by consumers on the degradation of miRNAs in milk; we also5quantified miRNAs in dair...

Milk is a highly consumed product worldwide mainly because of nutrient content, but this rich composition associated to pH and water activity makes the milk an ideal medium for microbial growth. The thermal process is usually applied to guarantee microbial stability of milk, however, the heat promotes undesirable changes in the milk sensory and nutritional characteristics. Therefore, recent res...

It was hypothesized that differences in starch degradability account for observed differences in rumen vaccenic acid (t11-18:1) and milk rumenic acid (RA) concentrations. To test this hypothesis, starch degradability was varied through grain source and by processing. Eight Holstein cows in mid-lactation were assigned to two 4 × 4 Latin squares with four 21-day periods and four diets: dry rolled...

The Maghreb countries (Algeria, Morocco and Tunisia) have experienced since the early 1950s a rapid demographic growth coupled to a significant rhythm of urbanization. This has led to a marked increase in the demand of dairy products. In order to secure the supply, specific policies have been implemented. They mainly consisted in the establishment of a dairy industry, based on the processing of...

The paper surveyed the chemical composition and nitrogen distribution of Maiwa yak milk, and compared the results with reference composition of cow milk. Compared to cow milk, yak milk was richer in protein (especially whey protein), essential amino acids, fat, lactose and minerals (except phosphorus). The contents of some nutrients (total protein, lactose, essential amino acids and casein) wer...

Cheese-making technology aims to preserve milk so that consumption can be postponed for periods from a few days to several months. The preservation of the product is obtained mainly through lactic acidification and limited dehydration. These operations take place during the two first steps of processing, the setting (or coagulation) and draining phases. For many cheese types, a third phase know...

Milk is a food product that easily destroyed, therefore it needs to be handled or processed. One form of milk processing pasteurized milk. The Langgeng Mulyo Farmer's Group group dairy cows have only produced fresh without being Efforts diversify products are carried out by involving wives from the Farmer group. It hoped women farmer’s productive, and can increase family income. This community ...

The microflora of milk powder consists of a wide array of microorgan­ isms of which special attention is given to Bacillus endospores. Bacillus endospores survive pasteurization and spray drying and inhabit the final powder product in the dormant state indefinitely. Once the powder is re­ constituted, endospores may germinate, and through their enzymatic ac­ tivity become detrimental to quality...
