Flavor Profile

The sensory, volatile, and physiochemical profiles of nineteen commercial non-alcoholic pilsner-style beers produced by different production techniques were analyzed and compared with a dry-hopped non-alcoholic IPA. NABs made only with either physical dealcoholization or restricted fermentations differed significantly in chemistry and flavor. Generally, NABs produced by restricted fermentations were the most worty, thick, and sweet, whereas NABs that were physically dealcoholized had the lowest taste/aroma intensities and were the sourest, most thin, and least sweet. Interestingly, the method of dealcoholization had a minor impact on the flavor profile. The use of maltose intolerant yeast as well as the implementation of combined treatments, such as blending dealcoholized beer with beer containing alcohol, were the techniques found to produce NABs with more harmonious and multifaceted chemical and flavor profiles. NABs with increased hop aroma volatiles were the most harmonious, particularly highlighted by the NA IPA reference. Even though dry-hopped character might be atypical for pilsner-style beer, dry-hopping appears as a simple application to produce NABs with more harmonious flavor.

Usage Area

Lightweight materials were needed in many different areas, especially in order to reduce the required energy in areas such as automotive and aerospace industries. Metallic foams attract attention in lightweight material applications due to their unique properties. The pores in its structure provide advantages in many applications, both structural and functional by promising both ultra-lightweight construction, energy absorption, and damping insulation. Production techniques of metallic foams can generally be classified as liquid, solid, gas, and ionic state production according to the physical state of the metal at the beginning of the process. The production technique should be chosen according to the usage area and desired properties of the metallic foam and the suitability in terms of cost and sustainability of production. For this reason, the details of the production techniques should be known and the products that can be obtained and their properties should be understood. In this respect, this chapter emphasizes the production methods from past to present.

Production Techniques

Parameters from in vitro gas production techniques could have potential as predictors of dry-matter intake (DMI) and digestibility. Fermentation is usually carried out under conditions where nitrogen (N) is not limiting. Therefore where N supply is a constraint to intake and digestibility, prediction equations may be inaccurate. This study compared the use of N-free and N-rich media in an in vitro fermentation method (Theodorou et al., 1994) and studied the relationships between in vitro and in vivo parameters obtained using both media.

Production Techniques

The nylon bag technique is the standard technique used in many feed evaluation systems for ruminants. As the rate and extent of fermentation can also be determined with the gas production technique, this technique offers a potentially good alternative. Cone et al. (1998) showed that there was a good relationship between rate of degradation determined with the nylon bag technique and rate of gas production for organic matter and NDF in grass and grass silage. The aim of this study was to determine the possibilities for estimating nylon bag characteristics and calculation of the amount of fermentable organic matter (FOM) of concentrate ingredients with gas production parameters.

The nylon bag technique (NBT) has been used widely to characterize the washable (W), insoluble potentially degradable (D) and insoluble non-degradable (U) fractions of grasses (e.g. van Vuuren, 1993) and concentrates (Tammingaet al., 1990). Recently the gas production technique (GPT) has been proposed as a method to evaluate the fermentation characteristics of different foods (Theodorouet al., 1994). Both techniques have shown good correlation with dry matter intake (Khazaalet al., 1993). One of the potential advantages of GPT over NBT is the ability to differentiate fermentation patterns (Grootet al., 1996) that might be related to changes in food composition. This trial was part of a larger grazing experiment and aimed to compare GPT and NBT when applied to samples of ryegrass at different ages. A specific objective was to determine whether or not GPT could extract more information concerning the fermentation patterns of different ryegrass fractions and how these patterns changed as a result of plant maturity.

The existing production techniques of CMF (changeable multi-faceted plates) are not sufficient for production of tools with enhanced hardness parameters. In order to implement the production technique of composite CMF using layer by layer filling of press mold the research was conducted of the rotation speed of the press mold on the interface form of powdered materials phases. The suggested production method of composite CMF allows to enhance the hardness of cutting plates by 10–15%.

Technical Features

Textiles are evaluated mainly in regard to their visual appearance and technical features of textile production. From a modern point of view, it is their optical perception that is most often displayed in reconstructions. This, however, can rarely be achieved due to the poor and fragmentary preservation of archaeological textiles, which hinders gathering basic information about details of the production technique. Sources illustrating garments or putative textile patterns are often additionally consulted to achieve a better understanding of the textiles. Over the past two decades, the author has made an effort to present a different approach to textile archaeology, that is to demonstrate that the significance of textiles was predominantly governed by culture-specific production techniques whose differences were optical – i.e. at the first glance imperceptible even for experts. Textile patterns were predominantly applied during production. There was little subsequent embellishment where textiles acted as a carrier of the decoration. This means that patterns were rarely additionally integrated after the basic weave was complete, for instance as in the case of embroidery. In consequence, archaeological textiles assume a different cultural and historical significance than previously thought. They are not merely objects whose surfaces served as carriers for culture-specific patterns. In this context, embroidery is of particular significance, as it is a procedure for subsequent decoration of fabrics. In this article, the author presents prehistoric, including the Bronze and Iron Ages, textile finds that have been described as embroidery but are actually a combination of weaving and wrapping weaving techniques.

The tourism industry and craft products are two sectors that are long developed, complementing and strengthening each other. However, not many people consider ceramic craft product design with local culture basis. The research aims to show how local culture can be used as a source for ceramic craft product design ideas. Through design innovation and production techniques, we can increase varieties of ceramic craft product design. However, to make it come true, it needs a creative method as its solution. Creative method application includes: (1) Developing ceramic craft design for souvenir, based on local culture; (2) ceramic craft visual exploration for souvenir sourced from the local culture with Kerapan Sapi Madura (Cow Racing) as creation idea; (3) Ceramic craft production technique for souvenir; (4) Improvement and analysis of ceramic craft product innovation for a souvenir. (5) Analysis of creation result. Creation results can be seen from two design sets of ceramic craft products based on local culture with the “Kerapan Sapi Madura (Cow Racing)” theme as a product design idea.

Main Factors

Fat content is one of the main factors affecting the degradability and fermentability characteristics of oil-rich foods estimated by means of the in situ, in vitro and gas production techniques. Filtered fat, considered degraded/fermented, is of limited value to the rumen microbes and may inhibit fermentation. Pre-extraction of oil may be one way to solve this problem. The rumen organic matter degradability (OMD) and fermentability (FOM) of concentrate foods were evaluated in this study with and without oil extraction.
