Optimization of the technology for producing wine and grape distillates by complete processing of grape raw materials using the example of ‘Cristall’ grape variety

В рамках программы импортозамещения и развития виноградарско-винодельческой отрасли с глубокой переработкой сырья для восстановления ассортимента конкурентоспособных ликерных вин является актуальной организация производства винных и виноградных спиртов из разного виноградного сырья на базе действующих заводов первичного виноделия, в том числе и из вторичных продуктов виноделия. Целью исследований было провести предварительную оценку возможности получения винного и виноградного спиртов с объемной долей этилового спирта не менее 91 % путём глубокой переработки винограда сорта Кристалл с применением процесса ректификации. Объектами исследований являлись виноград сорта Кристалл урожая 2018 г., приготовленные из него столовый сухой белый виноматериал, виноградные выжимки, винный и виноградный спирты. Брожение виноградного сусла и сладкой виноградной выжимки проводили без применения ферментных препаратов и диоксида серы на чистой культуре винных дрожжей Saccharomyces vini . Предложено проводить прессование сбродившей виноградной выжимки на пневматическом прессе с отделением и последующей перегонкой жидкой фракции для первой дистилляции. На установке ЛУММАРК отработана методика полной перегонки виноматериалов до ректификата. Установлено, что качество получаемого спирта напрямую зависит от объемной доли этилового спирта. С уменьшением объемной доли этилового спирта получаемых спиртов растет количество нежелательных летучих компонентов, снижаются органолептические характеристики готового продукта. Показано, что предложенный процесс перегонки, включающий получение спирта-сырца на дистилляторе DV-3 и спирта - на малой ректификационной установке РУМ-3 позволяет получить винный или виноградный с объемной долей этилового спирта 94,5-94,6 % при выходе 85-86 %. In Russia, within the framework of the import substitution and development of the wine industry with deep processing of raw materials to restore the range of competitive liqueur wines, it is timely to organize the production of wine and grape distillates from various grape raw materials, including those from winemaking secondary products, based on existing primary wineries. The aim of the study was to conduct a preliminary assessment of the possibility of obtaining wine and grape distillates with a strength of at least 91% by deep processing of ‘Cristall’ grapes using a rectification process. The objects of research were ‘Cristall’ grape variety of the 2018 harvest, dry white base wine prepared from it, grape marc, wine and grape distillates. Fermentation of grape must and sweet grape marc was carried out without the use of enzyme preparations and sulfur dioxide on a pure culture of Saccharomyces vini wine yeast. It is proposed to press fermented grape marc on a pneumatic press with separation and subsequent distillation of the liquid fraction for the first distillation. A technique for the complete distillation of base wines into rectified material was developed using LUMМARK processing unit. It has been established that the quality of the distillate obtained directly depends on the volume ratio of ethyl alcohol. With a decrease in the volume ratio of ethyl alcohol of the obtained distillates, the amount of undesirable volatile components increases, and the organoleptic characteristics of the finished product decrease. It is shown that the proposed distillation process, which includes two stages: obtaining crude alcohol using a DV-3 distiller and alcohol using a small distillation unit RUM-3, allows to obtain wine or grape distillate with volume ratio of ethyl alcohol of 94.5-94.6 % at the exit of 85-86%.

Olives are characterized by a wide variety of volatile compounds, which are primarily products of microbial metabolism that contribute to the organoleptic characteristics of the final product and especially to its flavor. The volatilome in Spanish-style processed green olives of Conservolea and Halkidiki cultivars were analytically characterized. A solid phase micro-extraction (SPME) technique was used for the extraction of volatile components from the olive samples that were further identified and quantified by gas chromatography coupled to mass spectrometry (GC–MS). Eighty-eight (88) compounds were identified, including several aldehydes, ketones, acids, terpenes, but mainly esters and alcohols. Results showed that there were no significant differences in the qualitative composition of the volatile profiles between the two varieties. Acetic and propanoic acids, thymol, ethanol, 2-butanol, 1-propanol, ethyl acetate as well as ethyl propanoate were the most dominant compounds found in both cultivars. However, some quantitative differences were spotted between the two varieties regarding some of the identified volatile compounds. The quantity of 2-butanol was higher in the Halkidiki variety, while propanoic acid ethyl ester was found in higher amounts in the Conservolea variety. Furthermore, differences in the quantities of some volatile compounds over time were observed. Most of the identified compounds presented an increasing trend during storage.

Разработаны квасы брожения с использованием сухих экстрактов ягод малины, плодов черной смородины и облепихи. Исследованы экстракты плодов облепихи, ягод малины и черной смородины, полученные методом импульсно-вакуумной сушки (ООО «Вистерра», Бийск). Квасы готовили по промышленной технологии на концентрате квасного сусла. Экстракты добавляли в квас до начала брожения в дозировке от 2 до 8%. Образцы квасов с использованием экстрактов обладали приятным послевкусием, слабовыраженным плодовым ароматом. Полученные квасы характеризует высокое содержание аскорбиновой кислоты, мг/100 г, и полифенольных веществ, мг/100 мл, соответственно: контроль – менее 0,1 и 42,6; с добавлением экстракта малины 2,7 и 58,7; облепихи 6,9 и 47,7; черной смородины 4,6 и 66,2. Определено, что потребление одного стакана (200 мл) свежеприготовленного кваса с плодовым (ягодным) экстрактом позволяет удовлетворить от 100 до 150% суточной потребности в флавоноидах (85 мг/сут) и фенолокислотах (10 мг/сут), преобладающих в составе полифенольных веществ. С учетом уточненных норм МР 2.3.1.2432-08 определено, что квасы с экстрактами облепихи и смородины способны удовлетворить 10–15% физиологической потребности в витамине С взрослых и 15–45% – детей разных возрастных групп. Установлено, что добавление 6% плодово-ягодного экстракта к купажу перед брожением дает возможность вырабатывать квасы стандартного качества с оригинальными органолептическими характеристиками и повышенной пищевой ценностью. The kvasses of fermentation using dry extracts of raspberries, black currant and sea buckthorn have been developed. Extracts of sea buckthorn fruits, raspberries and black currants obtained by pulse-vacuum drying in LLC «Visterra» (Biysk) were studied. Kvasses was prepared according to industrial technology on a concentrate of kvass wort. The extracts were added to the kvass before fermentation in a dosage of from 2 to 8%. Samples of kvasses using extracts had a pleasant aftertaste, slightly pronounced fruit aroma. The resulting kvasses is characterized by a high content of ascorbic acid, mg/100 g, and polyphenolic substances, mg/100 ml, respectively: control – less than 0,1 and 42,6; with the addition of raspberry extract 2,7 and 58,7; sea buckthorn 6,9 and 47,7; black currant 4,6 and 66,2. It was determined that the consumption of one glass (200 ml) of freshly prepared kvass with fruit (berry) extract can satisfy from 100 to 150% of the daily need for flavonoids (85 mg/day) and phenolic acids (10 mg/day), which are predominant in the composition of polyphenolic substances. Taking into account the recommendations of MR 2.3.1.2432-08, it was found that kvasses with buckthorn and currant extracts can meet 10–15% of the physiological need for vitamin C in adults and 15–45% in children of different age groups. It was found that the addition of 6% fruit and berry extract to the blend before fermentation makes it possible to produce kvasses of standard quality with original organoleptic characteristics and increased nutritional value.

Complicated Task

AbstractOne of the topical approaches in analysis – outside the framework of traditional ones – is the formation of an integral “image” of the object. There are several approaches to solving the issue of obtaining as much information about the sample by a certain portion of its properties or its composition as possible. The first approach is forming a visual image (diagram) of several different properties of the analyzed sample, for example, the content of certain metals, acids, volatile components and some other indicators of wine quality. The consolidated image of a sample enables us to distinguish samples identical or similar in the selected properties from crucially different ones, even in case of an acceptable change of each indicator. Or else, using the consolidated image one can evaluate the direction of an image shift of a certain sample compared to the set of standard samples. The analysis of the geometry of the sample image by diverse indicators affords ground for assumption of the reasons for this deviation, as well as identification of falsification, or even solution of a more complicated task: detecting the area of growth of raw materials. The second approach is close to the first one in terms of methodology, but it digitizes properties using detectors and presents this as an image (“visual print” of response) of signals of these detectors on some components of the sample (presence, content). The feature of this approach is the use of a detector system that is non-selective and cross-sensitive to certain sample components. These sample images are produced using a system of “electronic nose”. “Visual prints” of array signals of different character sensors contain qualitative and quantitative information about the part of the analyzed sample which is sorbed by sensors. Despite the uncertainty of this information, “electronic noses” of piezoelectric type are widely used in the analysis of samples with complex varying composition.

Organoleptic Characteristics

Food fermentation has led to the improvement of the safety characteristics of raw materials and the production of new foodstuffs with elevated organoleptic characteristics. The empirical observation that these products could have a potential health benefit has garnered the attention of the scientific community. Therefore, several studies have been conducted in animal and human hosts to decipher which of these products may have a beneficial outcome against specific ailments. However, despite the accumulating literature, a relatively small number of products have been authorized as ‘functional foods’ by regulatory bodies. Data inconsistency and lack of in-depth preclinical characterization of functional products could heavily contribute to this issue. Today, the increased availability of omics platforms and bioinformatic algorithms for comprehensive data analysis can aid in the systematic characterization of microbe–microbe, microbe–matrix, and microbe–host interactions, providing useful insights about the maximization of their beneficial effects. The incorporation of these platforms in food science remains a challenge; however, coordinated efforts and interdisciplinary collaboration could push the field toward the dawn of a new era.
