Abstract:
At present, brewing is one of the most dynamically developing branches of the processing industry. To increase the economic efficiency of production and give beer a varied taste in production, it is proposed to use non-traditional plant raw materials. The replacement of expensive brewing malt with unmalted carbohydrate-containing materials is one of the most important and urgent tasks of the brewing industry. This article examines the fermentation process of beer wort with the addition of apple juice and honey base. The lack of nitrogen-containing and phosphorus-containing compounds in honey a

Abstract:
Besides their best-known uses in the food and fermentation industry, yeasts have also found application as microcapsules. In the encapsulation process, exogenous and most typically hydrophobic compounds diffuse and end up being passively entrapped in the cell body, and can be released upon application of appropriate stimuli. Yeast cells can be employed either living or dead, intact, permeabilized, or even emptied of all their original cytoplasmic contents. The main selling points of this set of encapsulation technologies, which to date has predominantly targeted food and—to a lesser extent—pha

Abstract:
ABSTRACTAlcoholic fermentation (AF) conducted bySaccharomyces cerevisiaehas been exploited for millennia in three important human food processes: beer and wine production and bread leavening. Most of the efforts to understand and improve AF have been made separately for each process, with strains that are supposedly well adapted. In this work, we propose a first comparison of yeast AFs in three synthetic media mimicking the dough/wort/grape must found in baking, brewing, and wine making. The fermentative behaviors of nine food-processing strains were evaluated in these media, at the cellular,

Abstract:
Saccharomyces cerevisiae is a common yeast used as a fermenter in the home industry. This yeast is able to grow in media like waste materials. One of the waste materials that can be used as a medium of yeast growth is waste of coconut water. The use of coconut water as a medium of yeast propagation has been widely used in some types of yeasts. The intake of nutrients such as phosphate will make the yeast cells begin to grow and work faster. The yeast cell takes phosphate as ATP. Khamir will turn it into a phosphate polymerization form that is often found within the mitochondria of these cells.

Abstract:
Pulsed light is an emerging non-thermal technology viable for foodstuff sanitation. The sanitation is produced through the use of high energy pulses during ultra-short periods of time (ns to µs). The pulsed light induces irreversible damages at the DNA level with the formation of pyrimidine dimers, but also produces photo-thermal and photo-physical effects on the microbial membranes that lead to a reduction in the microbial populations. The reduction caused in the microbial populations can reach several fold, up to 4 log CFU/mL decrement. A slight increase of 3 to 4 °C in temperature is observ

Abstract:
Immobilized cell technology (ICT) has been attracting continual attention in the brewing industry over the past 30 years. Some of the reasons are: faster fermentation rates and increased volumetric productivity, compared to those of traditional beer production based on freely suspended cells, as well as the possibility of continuous operation. Nowadays, ICT technology is well established in secondary fermentation and alcohol- free and low-alcohol beer production. In main fermentation, the situation is more complex and this process is still under scrutiny on both the lab and pilot levels. The p

The process of baker's yeast production generates high strength industrial effluents with a chemical oxygen demand (GOD) of 10 000-30 000 mg/liter. In addition to the sugar containing substances sulphur and nitrogen containing substances are added to the batch processes to promote cell growth and to control pH. This results in rather high concentrations of sulphate 0000-2700 mg/l) and ammonia (400-900 mg/l) in the wastewater. The treatment plant at Pakmaya

The widening gap between wine production and wine consumption, the shift of consumer preferences away from basic commodity wine to top quality wine, and the gruelling competition brought about by economic globalisation call for a total revolution in the magical world of wine.

Second, an attempt of estimating storage carbohydrate contents in yeast cells through an extension of this model is presented.

Abstract:
One of actual global problem is clothes and packing materials biodegradability leading to tremendous water contamination. In order to develop ecologically friendly, game-changing in global industry fabric production, we propose a concept to implement kombucha. Kombucha is a symbiotic bacteria and yeast multispecies consortium producing the most abundant polymer on Earth - bacterial cellulose. There are many advantages of bacterial cellulose that are widely used in medicine, material science, food industry and waste management. Unfortunately: long time of bacterial cellulose polymerisation process, lack of its control, diversity in biological composition, finally, acidic smell and disturbances of kombucha growth - all this issues limit the interest of kombucha use to replace easy-accessible and widely applied synthetic materials. In this chapter will be described a revolutionary concept to develop practical and sustainable use of bacterial cellulose as natural alternative for synthetic materials, particularly for a synthetic fabrics and plastics replacement. The optimal cultivation conditions and examples of bacterial cellulose in applications for daily life will be explained.

Conversion of citrus processing waste (CPW) generated during juice production into value added co-products is an important aspect of the juice industry as it offers a solution to waste disposal issues. Currently the practice of drying citrus waste to produce citrus pulp pellets (CPP) for use as cattle feed is profitable. However, until the recent rise in value, CPP value was marginal and often did not meet production costs. Another concern has been volatile organic emissions during CPP production. Only one third of the residual peel oil present in citrus waste is recovered during CPP productio
