A support material is used, in a non-arranged way, increasing the active biomass accumulation capacity and allowing downwards flow in the digestion tank.
Universidad de Cádiz posted this:New process for using beer bagasse (spent brewers grain) to obtain raw materials for the production of biofuelsCurrently, considerable quantities of lingo-cellulosic residues are generated continuously in many sectors of the agro-food industry. If these can be suitably processed, they are of great commercial interest to industry as potential raw materials for the production of biofuels and a variety of other high value-added products. The residual biomass of the agro-food industry typically has a high content in lipids, carbohydrates, proteins and other compounds of industrial interest. The only limitations to its use as a precursor of biofuel are the economic viability of the process for obtaining these precursors and their quality. One of the byproducts of special interest for this application is spent beer grain, also known as bagasse; given the existing lack of commercial value, this bagasse is widely available as a low-cost raw material. Currently, the principal application of bagasse is as feedstuff for livestock. In general, bagasse does not represent a source of income for breweries, and the reason why it is sold is to minimize the associated problems of waste management and disposal. The UCA research group on "Allelopathy in Higher Plants and Microorganisms" (FQM- 286) has developed an acid hydrolysis procedure whereby precursor materials for biofuels and other high -value-added products are obtained from beer bagasse. Its content in lipids and food fibre (equal to or more than 5% and 20%, dry weight, respectively), make it an ideal material for this application. This would represent a more attractive commercial outlet for many of the residues resulting from operations of the agro-food industry, and in particular, for beer bagasse. The object of the process is to obtain two different products. The first is an oil consisting mainly of the fats contained in the bagasse; the second is a substance rich in sugars or molasses. The oil is of interest as raw material for the production of biodiesel by the process of transesterification; the molasses can be employed as raw material for the production of bio-ethanol by means of fermentation. Molasses can also be formulated as sugar, after a crystallization process. The oil would be particularly useful for correcting the viscosity of biodiesel, thus achieving the optimum parameters for its use as biofuel. In outline, the process developed by the research group consists of a principal line, in which a series of operations take place for the conditioning of the bagasse, such as milling, extraction of lipids and the separation of the resulting solids. Downstream, this line divides into two secondary lines: in one line, for production of oils, the solvents from the prior extraction stage are separated out; in the other secondary line, for the production of molasses, an acid hydrolysis of the sugars is carried out. Another significant feature is that the optimum operating mode of the process is continuous operation, although batch loading is also accepted.
Universidad de Alicante posted this:New Food Disinfection System Using Ultraviolet Germicidal Radiation• Non transparent liquid foods, having low UV radiation penetration depth, are fully sterilized. • It is an alternative to thermal processes because it provides similar results being less aggressive to the product characteristics. • Superficial disinfection of solid surfaces can be accomplished. • Low cost and effective technology. • UV disinfection can be implemented anyway in the production process.

As well as their use as substitutes for the addition of sulfur dioxide in wines or other food products. The chitosan films have many applications due to their antioxidant and antimicrobial properties. The limitation in their use is that chitosan is soluble in acidic aqueous media. Despite the numerous applications of chitosan, was never described the production of chitosan with natural compounds that are stable in acidic and with high antioxidant activity, maintaining the antimicrobial activity of chitosan. Has never been reported the use of chitosan as a substitute of the addition of sulfur dioxide in wines or other food products, pharmaceutical or other related areas.
