Development of Processing Technology and Quality Evaluation of Vermouth Development of Processing Technology and Quality Evaluation of Vermouth * Elena MUDURA, Teodora Emilia COLDEA Faculty of Food Science and Technology,[email protected] University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, Manastur Street, No. 3-5, 400372, Cluj-Napoca, Romania; *Corresponding author, e-mail: Bulletin UASVM Food Science and Technology 73(1) / 2016 ISSN-L 2344-2344; Print ISSN 2344-2344; Electronic ISSN 2344-5300 DOI: 10.15835/buasvmcn-fst:11980 ABSTRACT Vermouth is the most consumed aromatised wine. The present study developed a processing technology for herb macerates used as ingredients in the processing of vermouth. Cold maceration in ethanol solution of 45% vol. was proceeded for the extraction of herb aroma and colour components in stainless steel tanks. The mixture was pressed and stored separately. The adequate quantity of sugar, citric acid and wine were prepared for the batch of vermouth. Vermouth was left for maturation for 2 months in stainless steel tank. To obtain perfectly clear and stable product, conditioning and stabilization treatments were conducted. All the chemical parameters were evaluated using adapted reference methods. The addition of herb macerates to the wine increased the vermouths alcoholKeywords: content to 17.2 % vol.

  • Effect of Temperature and Duration of Maceration on Colour and Sensory Properties of Red Wine: a Review
    Effect of Temperature and Duration of Maceration on Colour and Sensory Properties of Red Wine: A Review Hasan Şener Biotechnology Branch, Institute of Natural and Applied Sciences, Ege University, Turkey Submitted for publication: December 2017 Accepted for publication: March 2018 Key words: Cold maceration, skin contact, total phenols, aroma, colour, wine The maceration process plays an important role in the composition of the colour and sensory properties of red wine by facilitating the extraction of phenolic and aromatic compounds found in grapes. This review summarises the key findings from a study of the literature associated with research on the effects of the temperature and duration of maceration on the phenolic content, colour and sensory properties of red wine. In the past, many researchers have reported that higher maceration temperatures increase the extraction of phenolic compounds and enhance red wine colour, but low-temperature pre-fermentative techniques have become more popular in recent years due to their positive effects on wine composition, including lower oxidation of anthocyanin pigments and aroma compounds, inhibition of undesirable enzymatic activities, and an environment that is less conductive to microbial growth. Macerations carried out at low temperature ranges (10°C to 15°C) result in red wines with the highest levels of total phenolic content, anthocyanin and colour intensity, and richer fruity, flowery and spicy aroma. The duration of maceration has also been shown to have significant effects on red wine phenolic compounds, colour properties and the relevant sensory attributes. Studies show that prolonged maceration leads to a stable red colour, as well as richer tannin content, polymeric pigments and astringency.

  • Research Paper the Effect of Salinity Stress and Temperature Levels
    Academia Journal of Medicinal Plants 9(6): 070-077, June 2021 DOI: 10.15413/ajmp.2021.0107 ISSN: 2315-7720 ©2021 Academia Publishing Research Paper The effect of salinity stress and temperature levels on germination characteristics of four medicinal plants seed Accepted 9th March, 2021 ABSTRACT Cultivation of medicinal plants has been economically beneficial for pharmacy and medicine. These plants are stores of active and valuable secondary metabolites that can be converted into various drugs, some of which are life-saving. However, it is difficult to start a large-scale and commercial cultivation of these plants because most of the arable land is used to produce strategically essential crops. Other uncultivable lands are often affected by various abiotic stresses, one of the most important of which is salinity. Germination of plants is one of the important stages during their growth period that is often affected by environmental stresses, especially salinity. In this study, the seeds of medicinal plants such as Lavender (Lavandula angustifolia), hyssop (Hyssopus officinalis), black cumin (Nigella sativa L.) and Scrophularia (Scrophularia striata) were subjected to salinity stress at 20, 25 and 30°C in order to determine the germination characteristics of their seeds. The results of this experiment generally showed that with increasing salinity stress at different temperatures, all germination characteristics including germination percentage, germination rate, shoot length, root length, shoot dry weight, root dry weight and seed vigor index decreased. It seemed that in order to Yousef Hakimi grow plants commercially, low salinity soil and water are needed to get the best yield.

Now talking about wines, the Wine and sprit association of the Great Britain has sponsored the following definition of Wine ―Wine is an alcoholic beverage obtained from the fermentation of the juice of freshly gathered grapes. Fermentation is conducted in the district of origin according to local customs and traditions. To bear the name Wine, the product must come only from grapes. If made from other fruits; the fruit name must be put before the tern Wine eg. Blackberry Wine, Apricot Wine, Fig Wine. Only a small part of the world is Wine producing. This is because the grape will only provide juice of the quality required for conversion into consumable Wine where two climatic conditions prevail. 1. Sufficient sun-shine to ripen the grape 2.

  • Refined Exposure Assessment for Caramel Colours (E 150A, C, D)1
    EFSA Journal 2012;10(12):3030 STATEMENT OF EFSA Refined exposure assessment for caramel colours (E 150a, c, d)1 European Food Safety Authority2, 3 European Food Safety Authority (EFSA), Parma, Italy ABSTRACT This EFSA statement is a refined exposure assessment of caramel colours (E 150a, E 150c and E 150d) taking into account additional information on its use in foods as consumed. The EFSA Panel on Food Additives and Nutrient Sources added to Food (ANS) adopted a scientific opinion on the re- evaluation of caramel colours (E 150a, E 150b, E 150c, E 150d) used as food additives in 2011. In that opinion, the Panel concluded that the anticipated dietary exposure of child and adult populations may exceed the Acceptable Daily Intake (ADI) for caramel colours E 150a, E 150c and E 150d, but exposure estimates to E 150b were below the ADI. Following this conclusion, new data from industry were submitted to EFSA providing updated use levels of caramel colours in foods ready to be consumed. A refined exposure assessment was performed for caramel colours that were exceeding the ADI in ANS Panel opinion (EFSA, 2011a) i.e. E 150a, E 150c and E 150d and concluded that the anticipated dietary exposure are considerably lower than in the previous exposure assessment. However, toddlers and adults have a higher exposure to caramel colour E 150c and could still exceed the ADI of 100 mg/kg bw/day for this caramel colour. The estimated combined exposure to the four caramel colours (E 150a, E 150b, E 150c, E 150d) are considerably lower and the group ADI of 300 mg/kg bw/day is not exceeded for any population group in the current review.

  • Hyssop Herb Yield and Quality Depending on Harvest Term and Plant Spacing
    Acta Sci. Pol., Hortorum Cultus 10(3) 2011, 331-342 HYSSOP HERB YIELD AND QUALITY DEPENDING ON HARVEST TERM AND PLANT SPACING GraĪyna ZawiĞlak University of Life Sciences in Lublin Abstract. Hyssop (Hyssopus officinalis L.) is an oil plant, acts antiseptically and stimu- lates digestion. It is applied both for curative and culinary purposes. Studies conducted in the years 2006–2008 were aimed at the effect of plant harvest term (mid June – plants in vegetative phase, mid July – beginning of flowering, mid August – full blooming, mid September – after flowering) and plant spacing (30 × 30, 40 × 40, 50 × 50 cm) upon yielding and quantity of hyssop herb. Studies were conducted at one-year plantation es- tablished from seedlings. Yield of fresh, dry herb and yield of herb without stems was significantly dependent upon the examined factors. Significantly greater fresh herb yield was obtained from plants after flowering (on average: 2.32 kg.m-2), just like the dry yield and yield of herb without stems. In the analysis of the effect of plant spacing upon hyssop yielding, it was revealed that the highest fresh herb yield (on average 1.47 kg.m-2) was from plants grown in the spacing of 40 × 40 cm, similarly to yield of the dry herb and yield of herb without stems. No significant effect of plant spacing was found on the con- tents of dry matter, L-ascorbic acid, chlorophyll, carotenoids, oil, tannins and flavonoids. It was demonstrated, however, that the harvest term significantly effects the contents of L-ascorbic acid, chlorophyll, carotenoids and essential oil in hyssop herb.
