The knowledge of solid loss kinetics of foods during digestion is crucial for understanding the factors that constrain the release of nutrients from the food matrix and their fate of digestion. The objective of this study was to investigate the solid loss of carrots during simulated gastric digestion as affected by pH, temperature, viscosity of gastric fluids, mechanical force present in stomac...

The state in which a protein substance exists depends upon the nature of its combination with acids or bases and is changed by change in the protein compound. The nature of the compound of a protein that exists at any hydrogen ion concentration can be ascertained if the isoelectric point of the protein is known. Accordingly information regarding the isoelectric points of vegetable proteins is o...

ABSTRACTThe purpose of this study was to determine the right concentration pineapple juice addition carrot hard candy. Knowing chemical characteristic candy added with juice. Evaluating panelist preference for This used a completely randomized design (RAL) method consisting 5 treatments and 3 replications juice: (10%), (15%), (20%), (25%), (30%). Then analysis carried out water content, ash con...

Response surface methodology (RSM) was used to optimize pizza cheese containing carrot extract. The effects of two important independent variables including soybean oil (5%-20%) and carrot extract (5%-20%) were studied on physicochemical and textural properties of pizza cheese containing carrot extract. According to the results, RSM was successfully used for optimizing formulation of pizza chee...

Mechanisms of in...

The effect of onion juice on the whitening fresh-cut carrots during storage was explored to optimize processing technology carrots. Using fresh carrot and as raw materials whiteness value reference index, process parameters were optimized by response surface methodology (RSM) based single factor experiment, physiological biochemical indexes determined. Results showed that conditions follows: co...

This study aimed to evaluate the blueberry and carrot juice blend as a fermentable substrate for Lactobacillus reuteri LR92, in order to develop a fermented non-dairy functional beverage. Analysis of cell viability, pH, and acidity were performed during the fermentation process. The resistance of the microorganism in the blend, under simulated gastrointestinal conditions and in storage at 4 ◦C ...

O'Bannon and Taylor reported that carrot disks on 1% agar were suitable for culturing Pratylenchus brachyurus (4). We found that they are suitable also for Pratylenchus vulnus, and easier to prepare than the alfalfa tissue we have used in the past (3). Our observations on carrot disks during the last 3 years may be useful to others. Initially, many of the carrot disks rotted, and a variety of s...

For the quanti®cation of aand b-carotene including the cis-isomers of b-carotene in carrot juices and vitamin supplemented (ATBC) drinks, a rapid and artefact-free method was developed. The analytical procedure involves the extraction of carotenes with a mixture of acetone-hexane and their determination by HPLC using a C30 stationary phase. No saponi®cation prior to HPLC is required. The method...
