2019
Marlon Numpaque | Tuba Şanlı | Elif Ayse Anli
The first introduction of human being with milk begins with human milk during infancy, continues with very commonly with cow’s milk and may be with other milk types during lifetime. Cow breeding and utilizing its milk in nutrition is widespread in the world. There are particular species common to their area such as donkey, camel, mare, yak and llama have an important share in milk production in the world. Donkey milk has higher serum protein and lower casein content being similar to human milk so regarded as a good and safer alternative for infants suffering from cow’s milk protein allergy. Mare milk is used as a therapeutic agent for the treatment of some metabolic and allergic illnesses. It is generally consumed as fermented product. Llama milk contains higher amounts of calcium and phosphorus than cow's milk. Camel milk has high vitamin and mineral content and has claimed to have medicinal proteins. Its casein micelle size is larger naturally and it has lower amount of κ-casein these cause difficulties in cheese making and affect curd quality. Reindeer milk is an energy dense food with its high fat and high protein content when compared to cow’s milk. Its high protein content could make it suitable for protein supplementation. Its low lactose content makes its consumption possible by lactose intolerance patients. Yak is richer in almost all main nutritional components when compared with cow’s milk. It can be used in cheese, butter making and dried milk products. The objective of this review was to represent the composition of different animal species’ milks; other than cow, buffalo, sheep and goat, their importance in nutrition and technological use.

The objective of this study was to develop and characterize a pH indicator based on chitosan (C) and starch (S) including anthocyanins from eggplant to indicate food quality changes through the detection of changes in the pH of packaged food products. Anthocyanins were extracted with solvents including ethanol and water (7:3, V:V) (EgP-E) and water (EgP-W) in acidic pH. The pH indicator films were obtained incorporating anthocyanin as 1.5 g extract/100 g film solution. The optical, mechanical and water vapor permeability properties were used to characterize the pH indicator films. The total monomeric anthocyanin content and phenolic content of extract solutions were also determined. Color variations of pH indicator films were measured by a colorimeter after immersion in different pH buffers (pH 2.0–10.0). Initially, dried C films and S based films were observed in a violet color and a magenta color, respectively. C and S films with anthocyanins showed color variations from pink (in acidic pH) to bluish-green (in neutral pH) and to violet (in basic pH) in different pH values. The water vapor permeability of films with anthocyanins was higher than films without anthocyanins. Additionally, C and S based films including anthocyanins extracted with water showed better permeability values. C:EgP-W and S:EgP-W films presented higher elasticity values when compared with films including ethanolic extracts (p

In the present study, antimicrobial effects of traditional beverages produced from grapes such as traditional grape pickles, grape juice, home-made hardaliye, and commercially produced hardaliye were investigated using microdilution method against Staphylococcus aureus ATCC 6538P, Escherichia coli ATCC 25922, Salmonella Typhimurium NRRL B4420, Bacillus cereus ATCC 10876, Saccharomyces cerevisiae NRRL Y-12632, Lactobacillus acidophilus La-5 and L. rhamnosus LGG. In addition, total phenolic content was measured by the Folin-Ciocalteau method, and antioxidant activities of grape products were evaluated using DPPH assay. Results showed that grape containing beverages have antimicrobial effects on S. aureus, E. coli, S. typhimurium and B. cereus at various minimum inhibitory concentration (MIC) values in the range of 4.53-150 mg/mL. The lowest MIC value of 4.53 mg/mL was obtained against E. coli for home-made hardaliye. MIC values of the traditional grape pickles were determined as 4.69 mg/mL and 9.38 mg/mL against S.aureus and E.coli, respectively. On the other hand, traditional grape pickles showed weak inhibitory effects against B.cereus with MIC value of 150 mg/mL. The bactericidal effect of these grape products was not detected for any of the test microorganisms however traditional foods produced by using grapes were showed inhibitory effects at different concentrations against tested microorganisms except for probiotics and the yeast. The total phenolic contents of the grape products were within the range of 865.27-2193.08 mg gallic acid equivalent (GAE)/L. Free radical scavenging activities of grape samples ranged from 46% to 90% and the grape juice was found to have the highest antioxidant activity. In conclusion, grape beverages have the potential to act as a antimicrobial and antioxidant agents for use as a natural antimicrobial and antioxidant product in the food industry.

In this study, the antioxidant activities and biochemical characteristics of Ulva rigida (Ulvophyceae) and Arthrospira platensis (Cyanophyceae) were determined. The extracts from two seaweed species were evaluated for their free radical scavenging activity, using the 1,1-diphenyl-2-picrylhydrazyl hydrate (DPPH) method, their total phenolic, flavonoid, and condensed tannin contents, through Folin–Ciocalteu, Quettier-Deleu, and Price methods, respectively. The extracts of two seaweeds showed a low free radical scavenging capacity in comparison with commercial antioxidant BHT (butylated hydroxytoluene), and vitamin C. The extract of U. rigida demonstrated greater antioxidant potential with a low IC50 (3.76±0.02 mg/g Ext.). The total phenolic contents were ranged from 2.21±0.08 (U. rigida) to 8.59±0.62 (A. platensis) mg GAE/g of extract. The highest flavonoid content was found in A. platensis as 22.70±0.65 mg rutin/g of extract. The contents of condensed tannin were measured 3.01±0.11 mg CE/g of extract for A. platensis and 3.76±0.06 mg CE/g of extract for U. rigida. According to results obtained, U. rigida and A. maxima possess antioxidant activity and could be used in for future applications in medicine, functional foods, and agriculture.

Chemical desiccation can advance the sunflower harvest time. Paraquat has been extensively used, but other less risky chemicals, as Carfentrazone and Saflufenacil, can rise as an alternative. Moisture levels of seed, head and the upper portion of stalk are all relevant for mechanical harvesting, but dry-down dynamics of each tissue is unknown. The aim was to study the dry-down dynamics of seed, head and stalk in sunflower genotypes sprayed with Paraquat, Carfentrazone and Saflufenacil after physiological maturity. Seven experiments were carried out in the field in Argentina (from 29 to 39º S) during 2014/2015 and 2015/2016. The genotypes used included hybrids and female inbred lines of both oil and confectionery types. The dry-down of sunflower plant was accelerated by desiccants with Paraquat, reducing seed and stalk moisture to a greater extent. The head moisture remained very high (>80 and 70%) during several days after application, without differences among desiccants and control. Dynamics of seed, head, and stalk moisture was not associated to vapor pressure deficit or meteorological conditions after chemical application. Loss of green color of leaves was not a reliable indicator of seed dry-down dynamics. Seed germination was not affected by chemical desiccation on either oil-type or confectionery female plants. Under broad conditions of these experiments, the Paraquat was effective for seeds/grains and stalks drying in both sunflowers hybrids and inbred lines. The slowly drying of heads makes it necessary to continue investigating with new doses and combinations of desiccants to ensure an optimal harvest. Desiccants were safe for seed germination, which benefits their usefulness in the seed industry.

This study was undertaken to assess the combining ability of 6 rice varieties, for viscosity parameters and determining gene action controlling Rapid Visco Analyser (RVA) characters. F2 progenies derived from a 6×6 half diallel mating design with their parents were grown in a randomized complete block design with three replications at the research farm of Rice Research Institute of Iran (RRII) in 2015. The diallel analysis by Griffing`s method indicated the involvement of additive and non-additive gene actions controlling RVA traits. For traits PV and FV RI18447-2 and IR50 were the best combiners for increasing and decreasing, respectively. Deylamani and IR50 were the best combiners for increasing and decreasing BV, respectively. Beside, due to more portion of non-additive gene action in controlling trait SV, The Gilaneh × RI18430-46, and Deylamani × RI18430-46 crosses were the best for increasing and decreasing SV, respectively. The high estimates of broad sense heritability and narrow sense heritability for BV and FV, indicated the importance of additive effects in expression of these traits. Therefore, selection base breeding methods will be useful to improve these traits and selection in the early generations could be done to fix the favourable genes. Low estimate of narrow sense heritability for SV revealed that non-additive gene effects play important role in controlling setback viscosity. So, hybrid base breeding methods will be useful to improve this trait.

Due to their widespread use in the pharmaceutical, cosmetic and food industries, medicinal and aromatic plants have gained importance with an increasing number of studies being conducted concerning the yield and quality characteristics of these plants. In breeding studies, selection is successful when there a correlation is established between the essential oil content, composition, and morphological and agronomic characteristics. The aim of this study was to address the correlation between the yield and quality of medicinal and aromatic plants to present a different perspective for breeding studies. Therefore, in this study, the relationship among the characteristics and the essential oil content of Izmir oregano (Origanum onites L.) and lemon balm (Melissa officinalis L.) plants were investigated, and correlation and path analyses were performed. There was a significant negative correlation between the essential oil content and fresh herb (-0.279*), dry herb (-0.281*), and dry stem yield (-0.283*) of Izmir oregano. However, no significant correlation was found between the essential oil content and these agronomic characteristics in lemon balm. Fresh herb yield had a significant positive correlation with dry herb (0.661**), dry leaf (0.690**), and dry stem yield (0.610**). Dry herb yield was significantly and positively correlated with dry leaf (0.510*) and dry stem (0.461*) yields. A significant positive correlation was also observed between dry leaf and dry stem (0.688**) yields. According to the results of the path analysis, while the maximum negative effect on the essential oil content of Izmir oregano was provided by dry herb (-48.05%) yield, the highest direct positive effect belonged to dry leaf (21.69%) and dry stem (15.13%) yields. Dry leaf yield (-51.61%) and plant height (-45.71%) were the parameters that had the highest direct negative effect on the essential oil content of lemon balm while fresh herb (33.50%) and dry herb (30.27%) yields were the source of the highest direct positive effect.
