THE RESEARCH FOUNDATION AND THE FUTURE*

The Research Foundation exists to advance the science of brewing and to contribute to the technical evolution of the Brewing Industry. It must study the scientific basis of current practice; it must anticipate and facilitate desirable technical change; it must provide a channel of communication into the Industry for facts and ideas arising in relevant parts of the academic and technical communities. Effective ness depends on good communication. There must be mutual interaction and feed back between Industry and the Foundation at all levels of seniority. The research staff of the Foundation must show the independence of mind and intellectual aggressiveness which leads to the development and acceptance of new ideas, whether of broad principle or of technical detail.     

THE ROLE OF THE FOOD INDUSTRY IN HELPING AMERICANS IMPROVE THE NUTRITIONAL QUALITY OF THEIR DIETS

Food serves three basic roles, physiological, psychological and cultural. As fuel for our biological furnace, food is the vehicle by which the essential macro-and micronutrients enter our body to provide energy, growth and repair. To improve the nutritional quality of our diets, it is essential that Americans better understand the three functions of food, and also the three basic principles of good nutrition, balance, variety and moderation. Industry can help by supporting ways to improve the education of both the teacher and the student; by more effective use and better message content of communication tools; and by creating and modifying products that have an enhanced nutrition profile.     

Impact of mass transport on microstructure of Granny Smith apple parenchyma during osmotic dehydration

The chemical components of foods are organized in microscopic structures that can modify mass transfer. The study of material penetration in foods can be made using X‐ray microanalysis. In order to study the microstructural behaviour when fruit was osmotically dehydrated, a glucose molecule modified with chloral (1,2‐O‐2′,2′,2′‐trichloroethylidene‐α‐D ‐glucofuranose) was used as an osmotic standard with chlorine detectable by energy‐dispersive X‐ray analysis. Parenchyma of Granny Smith apple is a simple tissue, so it was chosen as reference. The results show that both the apoplastic and symplastic routes played an active role in mass transfer. The osmotic agent penetrated both the symplast and apoplast well into the depths of the fruit, although greater deterioration of cells was observed near the surface.

MATHEMATICAL SIMULATION OF THE THERMAL BEHAVIOR OF FROZEN MEAT DURING ITS STORAGE AND DISTRIBUTION

During the various stages of marketing, frozen food products are frequently subjected to changes in temperature which affect their quality. In the present work, a mathematical model is developed to analyze the thermal behaviour of frozen meat subjected, under different insulation conditions, to thermal step functions and periodic fluctuations in temperature varying in amplitude and frequency. The heat transfer equation has been numerically solved, since it is a system with physical properties that vary with the temperature, and fluctuating boundary conditions. At the same time, laboratory experiments were performed to verify that the mathematical model is applicable to one-dimensional and three-dimensional heat transfer problems. The obtained results were compared with analytical solutions for the heat transfer equation, with constant coefficients, determining the temperature range for which it is possible to use average values in the physical properties.     

THE DETERMINATION OF FERMENTABLE EXTRACT IN BREWING WORTS

A method for determining the real fermentability of a standard Institute of Brewing wort is proposed for use in the Brewing Industry. The method is based on a system currently operating in the Distilling Industry using standard Distillers Co. Ltd (D.C.L.) ‘M’ type yeast. To provide a safeguard against variability in the performance of the yeast used, it is recommended that a standard malt (e.g. Institute of Brewing check malt A) of known fermentable extract should be used to check the condition of the yeast.

Beneficial effects of berry fruit polyphenols on neuronal and behavioral aging

It is becoming increasingly clear that although there is a great deal of research being devoted to elucidating the molecular mechanisms involved in aging, practical information on how to forestall or reverse the deleterious effects of aging may be years away. Therefore, it may be beneficial to determine other methods to improve the quality of life in the aging population. A plethora of epidemiological studies have indicated that individuals who consume a diet containing high amounts of fruits and vegetables may have a reduced incidence of age‐associated diseases such as cardiovascular or neurodegenerative diseases. Research from our laboratory has suggested that supplementation with fruit or vegetable extracts high in antioxidants can decrease the enhanced vulnerability to oxidative stress and inflammation that occurs in aging, and that these reductions are expressed as improvements in behavior. In addition to research indicating the antioxidant or anti‐inflammatory functions of the polyphenolic compounds found in these fruits and vegetables, further studies have suggested that other mechanisms such as cellular signaling may contribute to the beneficial effects of these compounds on aging.

The effect of daily temperature on truss flowering rate of tomato

The rate of appearance of tomato inflorescence is important parameter of yield prediction models. Number of macroscopically observable inflorescences related to unit time was used to characterize the rate of development in case of indeterminate tomato. Truss flowering rate showed similar pattern to truss appearance rate, and it was closely connected with temperature. The present experiments attempted to calculate functions that can estimate truss flowering rate up to the 10th truss. These functions are the basis of characterizing the whole flowering process in relation to temperature during the generative period of indeterminate tomato.

GENE TECHNOLOGY FOR INDUSTRIAL YEASTS

Yeast genetics is now available as a practical tool for the development of brewing industry practices. The contribution of Brewing Research Foundation work (1978–84) to recent advances is illustrated by the construction of brewing strains with superattenuating (amylolytic) or anti-contaminant properties. Approaches based on hybridisation (by rare mating) or recombinant DNA technology have been evaluated. Techniques developed for (i) gene transfer to brewing strains, (ii) ensuring stable inheritance of novel characteristics and (iii) exploiting the secretory ability of yeast strains, can be widely applied not only with brewing, distilling, baking or wine yeasts, but also in the use of yeasts to produce novel biotechnical products. ‘Spin-off’ from these studies includes valuable methods for differentiating or enumerating wild yeasts in brewery quality control.
