Approximately 20 mL of each sample was served in a 60-mL clear plastic cup coded with a three-digit number, and samples were evaluated in a monadic and random order. Below these thresholds, some IL concentrations enhanced ethanolic yields up to +34% by switching the metabolic status from respiratory to fermentative. We combined the acceptance test with the descriptive test to clarify the correlation between the intensity of specific attributes and the overall acceptability using Spearmans rank correlation coefficient.

Meta-Analysis of the Core Aroma Components of Grape and Wine Aroma. We consider that the astringency was decreased in the beverages with the initial pH of 5 due to a masking effect provided by the sourness. Approximately 60% of whey is industrially utilized, of which 58% is used as either edible lactose or dried whey powder, 35% is processed into whey protein concentrate and whey protein isolate, and the remaining 7% is processed into the so-called demineralized blends. Fermentation and drying of cocoa is a traditional process that is typically carried out on plantation by local farmers, whose methods may differ depending on the cocoaproducing region. Although the fermentation rate had been expected to increase at higher temperatures, the result was that the fermentation stopped halfway. Can. In terms of the intensity, we observed only differences in the intensity of sourness between the storage period of 0 weeks versus 2 weeks and 0 weeks versus 4 weeks, not in the intensity of bitterness. interesting to authors, or important in this field. 2017 May;182(1):229-237. doi: 10.1007/s12010-016-2322-2.

Characterization of volatile compounds in an alcoholic beverage produced by whey fermentation. 2007. In order to graphically represent the values and distribution of VOC concentration with significant differences among samples, a heat map clustered analysis (HMCA), based on a double hierarchical dendrogram with a heat map plot, was employed to represent the individual content values contained in the data matrix as colors, according to Martorana et al. For this reason it is only used in co- or Many food researchers have developed whey-based beverages using particular approaches to address the challenge of low sensory acceptance of whey: fermented beverages using kefir grains [10, 11] or lactic acid bacteria [12, 13], mixtures of fruit [14-16], and distilled liquors [17]. K. marxianus is a respiro-fermentative yeast likely to produce energy by either respiration or fermentation pathways.

J Biotechnol 182183: 3036. We expect the intensity of sourness to increase over time due to the oxidation of some ingredients in DMW-based beverages during storage, but we need to clarify the reason for this by analyzing the components.

The fixed parameters for each experiment were, when applicable, temperature of 28 C, pH 5.8 and 1% (m/v) of rice brain. From these results, we identified the optimal fermentation temperature as 30C. The evolutionary adaptation was carried out on the thermotolerant yeast Kluyveromyces marxianus NIRE-K1 at 45 C up to 60 batches to enhance its xylose utilization capability. the editor(s) disclaim responsibility for any injury to people or property resulting from any ideas, Belloch C., Barrio E., Garcia M.D. For Epub 2022 Aug 8. In conducting the sensory evaluation, the samples were first cooled in an ice bath. The pasteurized solutions were then inoculated with precultured yeast, were fermented under static conditions at 30C except during the trial for optimal fermentation temperature, and were periodically sampled to measure the consumption of lactose and production of ethanol. The frequency of ranking given to each DMW beverage fermented at selected initial pH values is as follows: pH 7 (1st, 18; 2nd, 20; 3rd, 19), pH 6 (1st, 16; 2nd, 23; 3rd, 18), and pH 5 (1st, 23; 2nd, 14; 3rd, 20). 2016;9:585594.

It will later focus on three specific areas: K. marxianus for bioethanol production; for the production of fragrance and flavors; and the future development of K. marxianus as a yeast cell factory. Whey Wine from Concentrates of Reconstituted Acid Whey Powder. K. marxianus is a natural thermotolerant yeast, which is a promising host for the production of cellulosic ethanol, chemicals and heterologous proteins [ 31, 32, 33, 34 ]. This type of The adapted. Among them, the Kluyveromyces marxianus CCT 7735 yeast stood out as being the best 2-PE producer. K. marxianus has been more widely adopted for industrial utilization compared to the predominant research species within the Kluyveromyces genus, Kluyveromyces lactis, due to its advantageous qualities in biotechnological application such as the ability to assimilate a wide variety of substrates, rapid growth rate, and thermotolerance [18, 19]. These results suggest that, in beverage storage, sourness has a greater effect than bitterness on the decrease of overall acceptability. ; Zacaria, J.; Delamare, A.P. It secretes hydrolytic enzymes, which could make it suitable for CBP, and it is able to utilize a wide range of substrates for aerobic growth. Bioutilisation of Whey for Lactic Acid Production. During fermentation, in addition to measuring lactose and ethanol concentrations, pH was also measured using LAQUAtwin pH meters (HORIBA, Ltd., Kyoto, Japan). We could not demonstrate that storage for up to 4 weeks reduced the acceptability of fermented DMW beverages. However, there are few studies on high-alcohol beverages that are expected to have a commercial value such as fermented whey beverages brewed with pure cultured yeast are not extensively produced. Kluyveromyces marxianus is one of the alternative yeasts for which an efficient transformation system was developed [ 1 ]. PeerJ 6:e4958. Multiple sensory evaluations, such as an acceptance test, a descriptive test, and a preference ranking test, were conducted to determine the optimal initial pH and storage period.

Although, in our investigation, we have not performed any research on genes and enzymes related to reactive oxygen species of K. marxianus in whey fermentation at selected temperatures, examinations of these genes and enzymes may reveal why the fermentation stopped under higher temperature conditions of 35C and 40C.
