Abstract:
... Ayran is a salty drinkable yoghurt, but lactose in ayran induces lactose intolerance. This can be overcome by production of lactose-free or lactose-reduced ayran. Milk with 50% and 100% lactose hydrolysis by β-galactosidase was therefore used for alternative lactose-reduced or lactose-free ayran production. Physicochemical, microbiological, and sensory analyses were performed during storage at 4 ° ...

Abstract:
... This paper aims to evaluate the impact of lactose free yogurt version on dynamic sensory perception and consumer acceptability. A total of 46 participants evaluated classical (SNY) and lactose-free (SLF-Y) commercial version of yogurts using the multiple-intake TDS technique, providing information about the dominant sequence of six flavor and texture sensory attributes. Moreover, information regar ...
... The consumption of probiotic foods is rather limited for many sectors of the population (vegans, lactose intolerant and celiacs). Therefore, it is necessary to offer functional alternatives for these sectors. Different red quinoa drinks were fermented with L. plantarum (QLPBB) and B. longum (QBLBB) at different times. Results showed that microbial concentration reached high levels (6–8 Log CFU/mL) ...

Abstract:
... This study applies the discrete element method (DEM) to the roller compaction process for the analysis of particle flow behavior, porosity distribution in the compaction zone and in the final ribbon, as well as the pressure distribution on rollers. The roller compaction setup was implemented utilizing a piston feeder and smooth roller surfaces. The parameters of the elastoplastic DEM contact model ...
... β-Galactosidase (lacA) from Aspergillus oryzae is widely used in the dairy industry. Its acidic pH optimum and severe product inhibition limit its application for lactose hydrolysis in milk. In the present study, structure-based sequence alignment was conducted to determine the candidate mutations to shift the pH optimum of lacA to the neutral range. The Y138F and Y364F mutants shifted the pH opti ...

Abstract:
... The fabricated NaY(WO₄)₂ was identified through diverse analysis methods. Therefore, to optimize NaY(WO₄)₂ morphology, saccharide carbohydrates were manipulated as a capping agent. In this study, glucose, fructose, lactose, cellulose, and starch were utilized as the capping agents. SEM images show that fructose was the optimal capping agent for achieving uniform and well-shaped nanoparticles. The ...
... A gluten and lactose-free plant-based yogurt-like was used as the main ingredient to produce a novel plant-based ice cream. The integrated approach used to investigate the main properties of the novel ice cream demonstrated similar nutritional label between the plant- and milk-based products with the former showing higher protein digestibility and absence of lactose. The lactic acid bacteria ferme ...

Abstract:
... Lactose intolerance in infants can be overcome by adding lactase enzyme formulations to milk, hydrolysing the lactose present. Commonly, such formulations require a significant incubation period after addition to milk to allow time for hydrolysis to take place at desired temperature. Such incubation is often problematic for household conditions, and therefore, formulations with short or, ideally, ...

Abstract:
... In this work we present a novel approach to model the micronization of pharmaceutical ingredients at process scales and times. 3D single-phase fluid-dynamics simulations are used to compute the gas velocity field within a spiral jet mill which are provided as input in a 1D compartmentalized model to calculate solid velocities along the radial direction. The particles size reduction is taken into a ...

Abstract:
... Recent trend in consumer preferences toward healthy and on-demand-to-make items has mandated food manufacturers to seek more efficient production processes in order to make their businesses sustainable. For powder producers in particular, the business models are drifting from ‘ready-made’ toward on-the-go items, thus requiring an urgent attention. Here, we present a long short-term memory (LSTM) m ...

Abstract:
... A miniature milk quality detection system based on ultraviolet/visible (UV/Vis) spectroscopy was designed. One hundred and eighty milk samples were obtained, and each sample was divided into two parts. One part was utilized as fresh raw (FR) milk, and another part was processed using a high-pressure homogenizer. The UV/Vis absorption spectra of milk samples were collected, preprocessed, and analyz ...

Abstract:
... In this study, the lactose/Whey Protein Isolate (WPI) composite hydrocolloids were prepared as an printing material for subsequent 3D printing. The results showed that the rheological, viscoelastic, thermal and mechanical properties of the studied hydrocolloids were composition dependent, which was directly linked to the printing fidelity of printed objects. The morphology of all printed objects s ...

Abstract:
... Lactose is commonly crystallized in the presence of whey proteins, forming co-crystals of lactose and proteins. This work hypothesized that flavonoids such as rutin or epigallocatechin-3-gallate (EGCG) could be incorporated into the lactose and protein co-crystal structure since flavonoids may interact with both lactose and proteins. The interactions between whey proteins and flavonoids were first ...
