Leaf senescence
Opis:
Efficacy of a growth promoter ascorbic acid (Vitamin C) on senescence deferral action was analysed using leaf discs of six wild ericoid plant taxa. Changes of some biochemical parameters like chlorophyll, protein, soluble and insoluble carbohydrates, RNA and DNA as well as activity of catalase enzyme were analysed as reliable senescence indices during detached leaf senescence of these six species under dark condition. With the progress of ageing duration from zero to 144 hours the levels of chlorophyll and proteins in leaf discs gradually declined in both control and ascorbic acid treated samples. However, in the chemical / Vitamin-C treated samples the rate of decline was found to be much slower. Concomitantly the levels of insoluble carbohydrate, RNA and DNA started declining right from 48, 96 and 144 hours of observation period both in treated and untreated samples. And here also ascorbic acid arrested the rapid rate of reduction of the levels of the biochemical parameters. On the other hand, soluble carbohydrate level started increasing irrespective of the treatments during the whole observation periods. However, the magnitude of increase was found to be low in case of the leaf samples which experienced treatment with ascorbic acid. The activity of the enzyme catalase was found to decrease progressively during the four observation periods (0, 48, 96 and 144 hours) regardless of the treatments. Ascorbic acid partially averted the rapid fall of the enzyme activity during the ageing periods. Ascorbic acid, a nonconventional senescence deferred thus seems to be a potent senescence deferral phytohormone /chemical / vitamin at least in case of six ericoid wild plant taxa.

The aim of this study was to investigate manganese and zinc recoveries from spent zinc-carbon and alkaline battery powder. The effect of sulfuric acid concentration, ascorbic acid dosage, reaction temperature and leaching time on zinc and manganese dissolutions was investigated. The optimum reductive acid leaching conditions were determined as: 3 hours, 70 °C, 0.5 M of sulfuric acid concentration, 13 g/dm3 of ascorbic acid dosage, 1/20 g/cm3 of solid/liquid ratio and 200 rpm of stirring speed. Under these conditions, dissolution efficiencies were 99.99% for Zn and 99.25% for Mn. In addition, dissolution kinetics of manganese was undertaken, and the activation energy was found to be 7.04 kJ/mol. Using 3 M NaOH as precipitating agent at room temperature, 95.35% of Zn (at pH 8) and 93.66% of Mn (at pH 10) were precipitated from the leaching solution. Under the same conditions, using 3 M KOH, precipitations of Zn and Mn were 91.63% and 96.39%, respectively. Based on the experimental results, a flowsheet of zinc and manganese recovery was proposed.

Opis:
Background. Vitamin C is one of the most important water-soluble vitamins. It is responsible for many important functions in the body, including: it has a positive effect on maintaining immunity, protects the body against free radicals, and also participates in the synthesis of hormones. Juices can be a good source of this vitamin. Most of the juices available on the market are processed products. Untreated juices, which do not contain added preservatives, sugar and are not pasteurized, constitute a smaller group on the market. Therefore, this group of juices can be a valuable product in human nutrition. Objective. The aim of the study was to analyze the content of ascorbic acid (AA), dehydroascorbic acid (DHAA) and vitamin C (TAA) in non-preserved juices, depending on their type and storage time. Material and methods. The analysis of TAA, AA and DHAA content in juices was carried out in ten types of non- preserved juices from two companies (A and B), purchased in a chain of retail outlets. The analyzed juices in company A were: sauerkraut and carrot, grapefruit, orange, apple and mandarin, while in company B: orange, apple, apple and quince, grapefruit and mandarin. In test 1, the first ten juices were analyzed, in test 2 - another ten juices after one month, in test 3 - juices from test 2 were used, and three days after opening the package and storing the juices in standard refrigeration conditions, the stability test of AA was analyzed. The AA and TAA contents were determined using the high performance liquid chromatography (HPLC) method. The DHAA content was calculated by subtracting the AA content from the TAA content. Results. The highest TAA content was found in citrus juices, i.e. grapefruit, orange and mandarin, and the lowest in sauerkraut and carrot juices and apple juice. Moreover, ascorbic acid in apple juice was characterized by the lowest durability. Conclusions. In the production of non-preserved apple juice, consideration should be given to the natural protection of ascorbic acid by the addition of citrus or other fruit juice, vegetable juice or by using a mild technology in the production process.

It was also found that spraying the vegetative parts of the bean plant with 250 mg/L ascorbic acid twice was attributed to increasing of magnesium significantly in the seeds of the bean plant, which amounted to 4.00 mg/g. otherwise, spraying with the same concentration, but once, led to a significant increase in phosphorous concentration, which reached 1.335 mg/g. The results also showed that one-time spraying of 500 mg/L ascorbic acid led to a significant increase in chloride concentration, which amounted to 0.395 mg/g compared to the control group. The results show that lead treatment had a more negative effect on the concentration of nutrients compared to the effect of nickel. It was found that spraying with ascorbic acid at a concentration of 250 mg/L was significantly superior to the concentration of 500 mg/L of magnesium, phosphorous, potassium and chloride in the seeds of bean plants. Also, spraying with ascorbic acid once was superior to spraying twice with the concentration of both magnesium and chloride.

Opis:
The electro-synthesis of poly(aniline-co-para–aminophenol) on graphite electrode was examined using cyclic voltammetry (CV) over the potential window of −0.2 V to 1 V in phosphoric acid medium, which was comprised of potassium chloride and para–Toluene sulfonic acid (pTSA) as electrolyte support. Fourier transform infrared (FTIR) spectroscopy was employed to identify the electro-synthesized copolymer while impedance techniques were used to determine charge transfer resistance (Rct) in modified and unmodified electrodes. After this, the electro-catalytic effect of the modified electrode on ascorbic acid was examined using differential pulse voltammetry (DPV) and a very strong response was observed. A negative shift of about 0.33 V was found in the peak anodic potentials for ascorbic acid. Measurement using DPV indicated a proper response by the electrode to a wide range of ascorbic acid concentrations, from 0.0001 to 0.0004 M. The peak anodic currents for increased concentrations showed a proper linear range.

Antioxidant vitamins, being effective free radical scavengers, can protect cellular DNA from oxidative damage. Therefore, in the present study we report on the relationship between basal level of 8-oxo-2'-deoxyguanosine in human lymphocyte DNA and the concentration of antioxidant vitamins (A, C and E). The average level of 8-oxo-2'-deoxyguanosine in lymphocytes of the studied group (15 males and 20 females) was 9.57 per 106 dG molecules. The endogenous level of ascorbic acid (vitamin C) in the plasma was, on average, 56.78 μM, while the mean concentrations of retinol (vitamin A) and α-tocopherol (vitamin E) were 1.24 μM and 25.74 μM, respectively. No correlations were found between individual 8-oxo-2'-deoxyguanosine levels in lymphocyte DNA and endogenous concentration of the vitamins.

Opis:
Aside from the possible health benefit of dietary consumption of glucosamine (GlcN), studies have also reported its flavour enhancing properties in varying food products. However, the impact of its inclusion on other quality attributes of meat products has been under-assessed. The present study examined the effect of the addition of ascorbic acid (0.1%) and varying levels of GlcN (0.75, 1.5 and 3.0%) on colour stability, textural as well as sensory attributes of beef burger. Except for L* (lightness) value, significant interaction (p<0.01) between storage time and added ingredient was observed for all colour parameters (a*; redness, b*; yellowness, chroma, and hue angle) in beef burger. Generally, although ascorbic acid preserved the colour attributes of beef burgers during storage, addition of GlcN resulted in the deterioration of these colour parameters. Whereas the present result did not confirm any flavour enhancing attributes of GlcN compared to control, GlcN improved beef burger’s yield and reduced product cook loss. However, level of GlcN above 1.5% resulted in significant flavour and textural deterioration (p<0.05), leading to decline in consumer acceptability of beef burger. This study showed that a moderate level of glucosamine could be used in meat products as a functional ingredient with some additional technological benefits and limited impact on sensory attributes. Ascorbic acid adequately protected the colour of beef burger during refrigerated storage.

Opis:
Over the last few decades, titanium alloys have become an important ingredient in many industrial sectors. In fact, titanium with additional characteristics, such as: high strength, heat resistance, low thermal conductivity, light weight and biocompatibility are being more and more used. However, the machining of titanium products tends to result in a thermal oxidation process and the development of a coloured layer. Therefore, a research regarding the thermal oxidation phenomena and its prevention was conducted. In this regard, cutting and grinding processes were experimentally investigated. Subsequently, L-ascorbic acid, a substance used against food oxidation, was used as an agent against oxidation during grinding. The main conclusions of the current study are the following: (1) Causes leading to the thermal oxidation during cutting and grinding were defined, (2) Prevention against oxidation was established by using L-ascorbic acid and strong alkaline water solution, (3) Optimum density of the solution with L-ascorbic acid and strong alkaline water was only 7.5 wt. % for grinding.

Opis:
In 2011-2013, a field experiment was conducted at the Plant Breeding Station in Polanowice near Krakow (220 m above sea level), on degraded Chernozem developed from loess. The field experiment was set up in a randomized block design with three replications. The experimental material used in this study was cv. Egida timothy grass. The aim of the study has been to test whether L-ascorbic acid supplementing for foliar fertilization with magnesium sulfate enhances magnesium absorption by plants and what effects it has on yielding and dry matter composition of timothy grass cut and used as forage. Three levels of L-ascorbic acid fertilization were applied (10, 20 and 30 g ha-1) with and without magnesium sulfate 7-hydrate. The plants were sprayed until wet, using 300 dm3 liquid per hectare. Spraying was performed 6-8 days from the onset of growth for the first harvest, and a week after cutting for the other harvests. Statistically significant improvement in yielding and forage quality was observed for the combined magnesium/ ascorbic acid fertilization. Fertilization with these two nutrients caused an increase in the total dry matter yield of timothy grass cv. Egida (together from 3 cuts), with differences reaching as much as 26% depending on the year (in the variant of combined magnesium sulfate and ascorbic acid application at 30 g ha-1). Another benefit of ascorbate application was an increase in forage quality (the content of crude protein, crude fat, water soluble carbohydrates and macronutrients). Best effects in terms of yielding and forage quality were obtained after a combined application of magnesium sulfate and ascorbic acid (30 g ha-1). Combined fertilization with magnesium sulfate and ascorbic acid tended to produce a stronger effect after periods of dry weather, which is discussed in the study.

Opis:
Pulp aeration markedly reduced the content of polyphenol compounds in apple juice. The largest quantities of these compounds were found in juice obtained from depectinized pulp and by a technology involving an addition of ascorbic acid to disintegrated apples. The juice obtained by technologies using pulp aeration or additions of ascorbic acid to disintegrated apples received the lowest organoleptic ratings. Changes in the contents of ferulic, m-coumaric, p-coumaric, caffeic acids and of the flavonols kempherol and quercetin appear to have no effect on the sensory properties of the juice.
Przeprowadzone badania dotyczyły wpływu: depektynizacji miazgi, depektynizacji moszczu, dodatku kwasu askorbinowego do rozdrabnianych jabłek oraz napowietrzania miazgi jabłkowej na zawartość związków polifenolowych w moszczach jabłkowych. W zależności od zastosowanej technologii moszcze jabłkowe zawierały: polifenoli ogółem (rys. 1) od ok. 300 mg/dm³ do ok. 2600 mg/dm³, katechin ogółem (rys. 2) od ok. 5 mg/dm³ do ok. 900 mg/dm³, leukoantocyjanidyn ogółem (rys. 2) od ok. 180 mg/dm³ do ok. 1700 mg/dm³. W badanych moszczach metodą chromatografii gazowej określono ilościowo zawartość 7 związków polifenolowych. Stwierdzono występowanie kwasów: ferulowego (rys. 3) od ok. 0,5 mg/dm³ do 12 mg/dm³, m-kumarowego (rys. 3) od ok. 0,8 mg/dm³ do 1,6 mg/dm³, p-kumarowego (rys. 3) od ilości śladowych do ponad 20 mg/dm³, kawowego (rys. 4) od ok. 5 mg/dm³ do ok. 50 mg/dm³ chlorogenowego (rys. 4) od ilości śladowych do ponad 90 mg/dms oraz dwóch flawonoli: kemferolu (rys. 5) do ok. 7 mg/dm³ i kwerceryny (rys. 5) do ok. 35 mg/dm³. Występowanie flawonoli stwierdzono przede wszystkim w moszczach otrzymywanych wg technologii stosujących depektynizację miazgi. W moszczach tych stwierdzono również występowanie kwasu szikimowego (rys. 4) w ilości do 18 mg/dm³.) Otrzymywane moszcze jabłkowe poddawano ocenie organoleptycznej (tabela) oceniając barwę, zapach i smak. W zależności od stosowanej technologii produkcji moszcze jabłkowe uzyskiwały od 1,6 do 4,8 punktu za barwę, od 3,0 do 4,1 za zapach i od 2,0 do 3,9 za smak. Najniżej oceniane były moszcze otrzymywane wg technologii stosujących napowietrzanie miazgi lub dodatek kwasu askorbinowego do rozdrabnianych jabłek. Sześciomiesięczny okres przechowywania moszczów w temperaturze pokojowej nie powodował istotnych zmian w ogólnej za wartości związków polifenolowych. Maksymalne straty nie przekraczały 15%. W przypadku indywidualnych związków polifenolowych straty dochodziły niekiedy do 50%.

Opis:
Pulses are a vital source of plant-based proteins and amino acids for people around the globe and should be eaten as part of a healthy diet to address obesity, as well as to prevent and help manage chronic diseases such as diabetes, coronary conditions and cancer; they are also an important source of plant-based protein for animals. Pulses provide protein and fibre, as well as a significant source of vitamins and minerals, such as iron, zinc, folate, and magnesium, and consuming half a cup of beans or peas per day can enhance diet quality by increasing intakes of these nutrients. The present attempt deals with comparison antioxidant activities of various sprouts of selected pulses. The β-carotene, ascorbic acid, total antioxidant activity, total phenol and flavonoid content of black gram (Vigna mungo), cowpea (Vigna unguiculata), desi chickpea (Cicer arietinum), and yellow mustard (Brassica alba) seeds and their sprouts (48 h) were determined. The parameters selected reflect the antioxidant capacity with respect to the dietary antioxidants (β-carotene, ascorbic acid) which were noted to be highest in chickpea sprouts and black gram sprouts respectively. The highest antioxidant activity in terms of % DPPH inhibition (49.837 ± 0.61 % ) and flavonoid content ( 211.06 ± 8.17 mg/100g ) was observed in cowpea sprouts. The highest total phenol content was noted in yellow mustard sprouts (58.45 ±6.67 mg/100g). Inclusion of pulses in the diet is a healthy way to meet dietary recommendations and is associated with reduced risk of several chronic diseases including cancer.
