Mandarin Market Segments Based on Consumer Sensory Evaluations
No full textNinety-five consumers in seven grocery stores tasted unidentified peeled sections of three mandarins (a tangerine, a satsuma, and a clementine), and provided demographic and purchase information. Forty-four percent of the respondents preferred tangerines, 34 percent satsumas, and 22 percent clementines. The probability of preferring each of type of mandarin was estimated from internal quality analysis of paired samples, as well as from demographic and purchase responses. Model simulations were used to recommend harvest standards for satsumas based on Brix-to-acid ratios.Demand and Price Analysis, Food Consumption/Nutrition/Food Safety,
Alkoholi- ja brix-pitoisuuksien analysointi siiderinvalmistusprosessissa
No full textSiiderin valmistuksen aikana sen alkoholi- ja brix-arvoja on tärkeää seurata, jotta lopputuotteen tuotelaatu ja tuoteturvallisuus pystytään varmistamaan. Tähän on olemassa useita tapoja, mutta tässä työssä käsitellään alkoholi- ja brix-arvojen mittausta tuotelinjasta Anton Paar L-Com 5500 tiheys ja äänennopeus anturilla. Työn tilaajana toimii Olvi Oyj:n panimo Pohjois-Savossa, Iisalmen kaupungissa.
Työn tavoitteena oli tutkia Anton Paar L-Com 5500 tiheys- ja äänennopeusanturin liittämistä osaksi siiderin valmistusprosessia. Työn kirjallisessa osuudessa tutkittiin siiderin komponentteja ja valmistusmenetelmiä, alkoholi- ja brix-arvoihin vaikuttavia tekijöitä, sekä prosessimittarin käyttöönottoa yleisesti. Työhön sisällytettiin myös siiderin valmistuksen työohjeiden päivitys. Työn käytännön osuudessa kaikille tuotteille kirjattiin reseptit tilaajayrityksen prosessinseurantaohjelmaan ja tuotteista otetiin tuoteajojen aikana kemiallisia prosessinäytteitä, joista analysoitiin alkoholi- ja brix-arvot. Saatuja arvoja verrattiin laboratorion vertailunäytteisiin.
Työssä saatujen tulosten perusteella todettiin, että mittarin käyttöönotto ei tämän opinnäytetyön valmistumishetkellä ollut mahdollista tulosten suuren vaihtelun vuoksi. Mahdollisiksi syiksi tähän vaihteluun epäiltiin laitteen asennusvirhettä ja tuotteen sisältämän hiilidioksidin vaikutusta mittaustulokseen. Näitä tekijöitä voitaisiin tutkia jatkotutkimusaiheena tälle opinnäytetyölle
Evaluation of Brix Refractometry for the Estimation of Colostrum Quality in Jennies
No full textDonkey placenta does not allow the passage of immunoglobulins; thus, foals are born hypogammaglobulinemic and an adequate intake of high-quality colostrum in the first 24 hours of life is crucial for the surviving. The study aims to assess the relation between colostrum immunoglobulin G (IgG) concentration evaluated by the single radial immunodiffusion (SRID) test and the Brix refractometer in donkeys to establish a cutoff value for high quality of colostrum based on Brix refractometry. Colostrum was collected at foaling, and at 6, 12, and 24 hours after foaling from the left and the right half of nine Amiata jennies. A total of 72 colostrum samples were analyzed. A Friedman test with a Dunn's test for multiple comparisons was used for assessing the differences between the left and right half at each sampling time. No differences were found between the left and right halves; the average value was used to analyze the effect of sampling time on the IgG concentrations and Brix values. The relationship between colostrum IgG concentrations (SRID test) versus Brix value and Brix value versus time was analyzed using two different mixed linear models. A strong statistically significant relation has been found between IgG concentrations and Brix values (R2 = 0.84). The relation between IgG concentrations and Brix refractometer showed a cutoff point of 17% Brix score for the identification of high-quality colostrum. The Brix value (%) decreased continuously from 16.29 by 0.29 × hour. Jennies’ and donkey foals’ management may be greatly improved using this simple and cheap device
Determination of colostrum quality using Brix refractometer in sheep
No full textIn this study, we aimed to determine the quality of colostrum in sheep by using Brix refractometer. The
research included 100 sheep of Merino X Kivircik crossbred. From each, we collected 15 mL of
colostrum samples in falcon tubes within the first 8 h after delivery. Mean colostral IgG level of sheep
was 156.68 ± 7.23 g L�1
, optical and digital Brix refractometer values (%) were determined as 27.43 ±
0.53 and 27.69 ± 0.60, respectively. Ewes carrying twin lambs produced significantly higher quality
colostrum than those carrying single lambs. However, parity did not affect the colostrum quality.
Optical and digital Brix values were correlated with gold standard radial immunodiffusion (RID)
colostral IgG level (r 5 0.70 and r 5 0.64, respectively). Also, optical and digital Brix refractometers
were found to be highly correlated (r 5 0.98, P < 0.001). While the optimal Brix value was 22% for the
50, 60 and 70 g L�1 IgG threshold values (by means of RID as the potential good quality threshold value
for ewe colostrum quality), this value was 23% for 80 g L�1
. We can conclude that Brix refractometers is
a valuable tool for determining ewe colostrum quality. A cut point of 22% Brix for defining good quality
colostrum in ewes was most appropriate for our data
Evaluation of brix refractometry to estimate immunoglobulin g content in buffalo colostrum and neonatal calf serum
No full textBrix refractometry has been widely demonstrated to be a useful tool for monitoring colostrum management program and passive immunity transfer (PIT) in Bovines, but its suitability has never been verified in Buffalo. Therefore, the objective of this study was to evaluate the utility of a simple and rapid tool such as a digital Brix refractometer to estimate colostrum quality and for evaluating the success of passive transfer of immunoglobulin G (IgG) in Buffalo calves. The optimal cut points levels for Brix Refractometry for distinguishing good‐ and poor‐quality colostrum and for assessing the adequacy of passive immunity transfer in calves were determined. For this aim, 26 first‐milking maternal colostrum (MC) were collected from first‐calf heifers. Blood samples were obtained from their calves at birth (T0) and 72 hours after (T3). Colostrum and Serum IgG content were determined by indirect enzyme‐linked immunosorbent assay (ELISA), whereas total protein (TP, g/dL) and percentage Brix (%Brix) by means of a digital Brix refractometer. The mean colostrum IgG was 64.9 ± 29.3 mg/mL. The mean serum %Brix at T3 was 9.6 ± 0.9 %. The mean serum IgG content at T3 was 11.1 ± 2.0 mg/mL. Pearson’s correlation coefficient (rp) was determined between Brix and ELISA measurements: colostrum %Brix showed a significant correlation with serum %Brix (rp = 0.82, p < 0.001); serum %Brix was highly correlated with serum TP (STP, g/dL) (rp = 0.98, p < 0.001) and serum IgG (mg/mL) (rp = 0.85, p < 0.001). A cut point of 18% Brix to estimate samples of MC ≥ 50 mg/mL from first‐calf heifers was more appropriate for the buffalo. A cut point of 8.4% Brix resulted in the greatest percentage of calf serum samples being correctly classified. Based on our findings, a digital Brix refractometer could be a useful tool to monitor colostrum quality and to estimate PIT in Buffalo calves

No full textThis research aims to determine the agronomic characteristics and Brix levels of three sorghum varieties (Sorghun bicolor (L.) Moench) at several growth phases. The research method uses an experimental method with a factorial completely randomized design (CRD), namely the first factor is variety and the second factor is growth phase. The experiment was carried out in the Glasshouse, Faculty of Agriculture, University of Mataram from May to September 2023. There were 9 treatment combinations, repeated 3 times, so there were 27 experimental units. Observation parameters include plant height, number of leaves, stem diameter, sugar content (brix), dry stover weight and sorghum yield and yield components. Data were analyzed using the Analysis of Variance (ANOVA) Honestly Significant Difference (BNJ) test at a significance level of 5%. The results showed that plant height, sugar content (brix), dry stover weight were significantly different between sorghum varieties, but the number of leaves and stem diameter were not significantly different (non-significant). The parameters of plant height, sugar content (brix), and dry stover weight of the three varieties were significantly different between growth phase treatments, while the number of leaves and stem diameter were not significantly different. All observed parameters were not significantly influenced by the interaction between variety factors and growth phase.

Phenotypic traits of phragmites australis clones are not related to ploidy level and distribution range
No full textBackground and aims: Phragmites australis is a wetland grass with high genetic variability, augmented by its cosmopolitan distribution, clonal growth form and large variation in chromosome numbers. Different ploidy levels and ecotypes differ in morphology and ecophysiological traits, and may possess different levels of phenotypic variation. The aim of this study was to quantify the natural variation in ecophysiological characteristics of P. Australis, and to explore whether differences in ecophysiological traits can be related to ploidy levels or to the geographic origin of the clones. Methodology: Fifteen clones of P. australis from Europe and Asia/Australia, representing five ploidy levels (4x, 6x, 8x, 10x and 12x), were grown in a common garden design for 119 days. Plant growth and light-saturated rate of photosynthesis (Pmax), stomatal conductance (gs), water use efficiency (WUE) and concentrations of photosynthetic pigments and mineral ions in the leaves were measured. Principal results: The growth of the plants and most ecophysiological parameters differed significantly between clones. The mean maximum shoot height varied from 0.9 to 1.86 m, Pmax from 9.7 to 27 μmol m-2 s-1, gs from 0.22 to 1.41 mol m-2s-1 and WUE from 13 to 47 μmol mol-1. The concentrations of chlorophylls did not vary significantly between clones, but the chlorophyll a/b ratio and the concentrations of total carotenoids did. The observed differences were not explained either by the ploidy level per se or by the geographic origin or phylogenetic relationships of the clones. Conclusions: Phylogeographic relationships in P. australis on a global scale do not mirror the environment where the adaptations have evolved, and high phenotypic variation among and within clones complicates comparative studies. Future studies aimed at explaining differences in plant behaviour between P. australis populations should be careful in the selection of target genotypes and/or populations, and should avoid generalizing their findings beyond the genotypes and/or populations studied. © The Authors 2012

Delayed First Milking in Unassisted Overnight Calving Did Not Affect the Quality of Colostrum but Influenced Serum Brix Refractometry in Holstein Calves at Two Days of Life
No full textTimely administration of good-quality colostrum represents the first farm strategy to avoid the failure of passive transfer (FPT). However, calves born during the night are likely to be fed later than recommended. Our aim was to evaluate whether night-occurring calving and delayed first milking affected colostrum quality and immune passive transfer. The dataset included 463 calvings. Four liters of colostrum were administered by an esophageal tube feeder. The mean Brix% of colostrum was 27.43%, while serum Brix% at two days of life in calves was 10.19%. According to the Generalized Linear Model, parity ≥ 4, calving months of March, April, and from September to November positively influenced the quality of colostrum. Dams carrying a male calf produced lower quality colostrum compared with those carrying a female calf (−2.78 ± 1.04 % Brix, p = 0.008); heavier female calves were associated with greater colostrum quality (0.29 ± 0.05 for each Kg increase, p < 0.001). Night-or daycalving had no effect on the quality of colostrum. The only factor influencing the serum Brix% of female Holstein calves at two days of life was the day-or night-occurring birth (−0.386 ± 0.188 Brix% in calves born during the night, p = 0.04). Our results showed that calves born overnight and fed the day after had decreased serum Total Protein concentrations as indicated by reduced Brix refractometer readings, compared with calves born during the day and fed quickly after birth. However, the administration of 4 L of high-quality colostrum likely improved their serum Brix% at two days of life. Alternatively, where the prevalence of good-quality colostrum is lower, improving calving supervision and ensuring timely feeding are important to reduce the risk of FPT
