Pepper fruits (Capsicum annum L. c.v. Caribbean) were treated with two commercial was coatings, Primafresh and Prolong. Fruits were sprayed with Primafresh (original concentration) and Prolong at 0.5% and 1.5% (w/v) concentration. Fruit samples were taken for analysis each of 5 days during 20 days from storage rooms at 1, 5, 10, and 15C. Parameters TSS, titratable acidity, pH, fresh fruit weight loss, texture, and dry matter content were analyzed. TSS and dry matter decreased with the storage time. Titratable acidity increased until 10 days after storage and decreased when fruit were stored for a longer time. The lowest texture deformation was observed at 1 and 5C. Coating treatments reduced the rate of fresh fruit weight loss of peppers compared to uncoated ones.

Banana is a climacteric fruit with a short shelf life. As a result, huge losses are incurred during handling in the value chain. The need to develop means of extending the shelf life and concomitantly maintaining the quality of the fruit after harvest has become very important. This study was conducted to determine the effects of two different edible waxing materials (beeswax and cassava starch) used as coatings on the quality and shelf life of Mysore banana. The study was conducted in the laboratory at the Department of Horticulture, Kwame Nkrumah University of Science and Technology–Kumasi. The experiment was laid out in a simple completely randomized design (CRD) and replicated three (3) times with three treatments (beeswax, cassava starch and a control). Parameters studied were: fruit weight loss, firmness, peel colour, pulp-to-peel ratio, moisture content (MC), dry matter content (DMC), total titratable acidity (TTA), total soluble solids (TSS), pH, green life and shelf life. The results showed beeswax and cassava starch had no significant effect (P>0.01) on peel colour, fruit firmness, TTA, TSS, DMC, MC and green life. Beeswax, however, kept weight loss minimal, and reduced TSS and the pulp-to-peel ratio of the fruits during storage. We conclude that beeswax was the best treatment in terms of waxing Mysore banana fruits to maintained its quality and ultimately prolonged its shelf life by about four (4) days more than the control.

Abstract Pepino dulce (Solanum muricatum Aiton) or Pepino has been growing to produce edible, juicy and attractive fruits. The imported fruits and national small scale of Pepino dulce production are currently stored and commercialized under the absence of postharvest handling recommendations. Therefore, this work aimed to evaluate the quality aspects of Pepino dulce fruits in distinct ripening stages, forms of packaging and conditions of storage. The trial was conducted in a 2x2x2 factorial scheme - 2 ripening stages (ripe and immature) x 2 forms of packaging (with and without wrapping in plastic film) x 2 conditions of storage (room: 25 °C ± 2 ºC and 57% ± 5% of relative humidity (RH); cold: under refrigeration 10 °C ± 2 °C and 85% ± 5% of RH) – in a complete randomized block design. Fruit quality attributes, such as vitamin C, chemical and phenolic content, fruit color (mesocarp), firmness, dry matter content, total titratable acidity (TA), total soluble solids and pH, were evaluated. Fruits showed a centesimal composition with low calories and a significant content of potassium (K), phosphorus (P) and magnesium (Mg), which can contribute to the daily supply of these elements. For commercialization purposes, the association of packaging (plastic wrapping film) and refrigerated storage (cold: 10 °C ± 2 °C and 85% ± 5% of RH) to maintain the characteristics of fruit quality after a 15 days period is more important than its individual use.

The experiment was conducted to examine the effect of freezing and defrosting methods on the quality of beef. Two types of beef samples named as fresh and cured beef samples were taken. Both types were divided into three sub divisions namely air, water and microwave oven. These samples were stored at -20°C temperature in the freezer for 90 days and analyzed on 10th, 45th and 90th day. The dry matter, crude protein, ether extract and ash percentages and standard plate count (SPC) were differed significantly (p<0.01) among the air, water and microwave defrosted samples. Up to 90th days of freezing at -200C dry matter content increased with the increase of storage time almost in all samples except microwave fresh samples. The protein content decreased with the increase of storage time from 10 to 45 days but increased from 45 to 90 days. The ash content decreased with the increase of storage time in case of fresh frozen samples but increased with the increase of storage time in case of cured frozen samples except microwave oven cured sample. Ether extract value gradually increased with the increasing of storage period in case of air fresh, water fresh, air cured and water cured frozen samples but decreased with the increasing of storage period in case of microwave oven fresh and microwave oven cured samples. The SPC value increased with the increase of storage time in case of all samples and differed significantly (p<0.01) among the parameters. The cured microwave defrosted beef was proved as the best technique of defrosting frozen beef.DOI: http://dx.doi.org/10.3329/bjas.v43i3.21649 Bang. J. Anim. Sci. 2014. 43 (3): 202-206

Aims: The aim of the study was to evaluate the nutritional content of various cultivars of taro acquired from All India Co-ordinated Research Project (AICRP) on tuber crops. Study design:Completely randomized design (CRD) at 5% level of significance. Place and duration of study: Department of Post Harvest Technology, faculty of Horticulture, Bidhan Chandra KrishiViswavidyalaya, West Bengal, India, between December 2019 and February 2020. Methodology: 8 cultivars of taro were evaluated for their nutritional contents in this study and their physical attributes such as cormel girth, length, specific gravity, number of cormels per plant and weight of cormel as well as yield per hectare was calculated. Chemical attributes such as titratable acidity, starch, ascorbic acid, total phenol and total sugar as well as reducing sugar content in each cultivar was also studied. Results: Analysis of variance showed significant variation among all the tested cultivars. Moisture content, total sugar and starch was recorded to be highest in the cultivar TTR-17-6 (72.233 %, 5.007 % and 31.805 % respectively). Total phenol (188 mg GAE 100 gm-1) and reducing sugar (2.817%) was found to be highest in TTR-17-5. Total soluble solids was highest in TTR-17-7 (3.867 0Brix). Dry matter content was highest in TTR-17-4 (37.333 %) and ascorbic acid was highest in TTR-17-2 (70.093 mg 100 gm-1). Conclusion: The eight cultivars of taro studied were found to be rich in sugars, ascorbic acid, total phenols and starch. They were observed to vary in cormel girth, length, weight, specific gravity, yield, moisture, dry matter content, TSS and titratable acidity. The cultivar TTR-17-6 was found to be very high in starch, total sugar and moisture content. Therefore, this cultivar may be of considerable importance in ameliorating malnutrition in poorly resourced areas of the developing countries. Cultivar TTR-17-2 was found to be high in ascorbic acid and hence can be further used by the plant breeders to develop more cultivars of taro that are rich in such phytochemicals.

Abstract The purpose of the study was to assess the storability of unripe hazelnuts in the husk of four cultivars: ‘Hall’s Giant’, ‘Catalan’, ‘Webb’s Prize Cob’ and ‘Cosford’. The nuts were stored in normal and controlled atmospheres, and in Xtend® bags for three months. A quality assessment was performed based on the following parameters: weight of the nut in the husk and without the husk, weight of the kernel, percentage of nuts with husk attached, dry matter content in kernels, infection with fungal diseases, and the presence of physiological disorders. The study demonstrated that hazelnuts stored in Xtend® bags and under a controlled atmosphere had a higher weight for the nut in the husk and without the husk, as well as a higher weight of the kernel and water content when compared to batches of hazelnuts stored in a normal atmosphere. The percentage of nuts remaining in the husk was also higher when stored under such conditions. For the majority of investigated cultivars the storage in Xtend® bags, and to a lesser extent under normal atmosphere conditions, resulted in a substantial increase in nuts infected with fungal and abiotic diseases. Among investigated cultivars, ‘Hall’s Giant’ turned out to be the most resistant to storage diseases.

The effect of fertilisation with fermented pig slurry on the quantitative and qualitative parameters of two kinds of tomatoes was assessed by means of pot trials. These trials were carried out between the years 2005 and 2008. Each trial involved four treatments, namely (a) control without fertilisation, (b) fertilisation with mineral fertilisers, (c) 50% nutrients in mineral fertilisers and 50% in fermented pig slurry, and (d) fertilisation with fermented pig slurry only. Besides the yield parameters, the following characteristics were monitored: dry matter content, vitamin C content, titratable acidity, nitrogen compounds, nitrates and selected elements (Pb, Cd, As, Zn and Hg) contents. The fertilisation method showed no statistically significant influence on many parameters (titratable acidity, Hg, As, dry matter, vitamin C and nitrates contents). These results showed that anaerobically fermented pig slurry can be a suitable alternative to the use of mineral fertiliser. They also showed that its use as an organic fertiliser did not impair the hygienic quality and safety of the vegetable products grown, as all tomato samples fulfilled the tested heavy metals and nitrates legislation limits. The fertilisation method showed a statistically significant influence on the yield. Diffe-rences occurred between the organic and mineral methods in the case of Cd, and between non-fertilised and organic methods in the case of Zn. The fertilisation method also significantly influenced N-compounds content in tomatoes. A statistically significant influence of the year was found with all parameters except zinc and vitamin C contents. The influence of cultivar was also found, but only in the case of zinc and dry matter contents.

The experiment was conducted to find out the effect of salt and storage temperature on the physico-chemical properties of meatball. For this purpose meatball samples were divided into two parts; one is called fresh meatball and another is preserved meatball at different temperatures. Then the fresh samples as well as the preserved samples were divided into four subdivisions. Then these are treated with different salt levels (0, 1.5, 3 and 5% salt level).These Samples were stored at 4oC and -20oC temperature. Samples preserved at 4oC were stored in the refrigerator for 21 days and were analyzed on 7th day, 14th day and 21st day and samples preserved at -20oCwere stored in the refrigerator for 60 days and were analyzed on 15th day, 30th day, 45th day and 60thday. Dry matter content of all the samples increased with the advancement of storage time, temperature and salt concentration. Ash value decreased with the increase of storage time. Fat value of all the samples decreased with the advancement of salt concentration, storage time and temperature. pH value of all the samples decreased with the increasing of salt concentration, storage time and temperature. Cooking loss of all the samples increased with increasing of salt concentration but decreased with increasing of storage time and temperature. Dry matter in fresh sample were less than in preserved samples. CP % of fresh beef meatball was 22.31, 20.55, 14.55 and 20.13 at different salt concentration. The values of CP, DM, Ash and Fat also varied among the samples significantly (P<0.01). Beef meatball can be refrigerated for 60 days in different techniques with more or less difference in the quality. Highly significant differences are observed in preserved samples than in fresh samples at different salt levels. Fresh beef meatball treated with 1.5% salt found to be more acceptable in terms of sensory evaluation.DOI: http://dx.doi.org/10.3329/pa.v24i1-2.19117 Progress. Agric. 24(1&2): 137 - 147, 2013

Abstract The aims of this work were to determine which storage conditions can preserve the quince quality (Cydonia oblonga Miller, Rosaceae family), stored in three different rooms with controlled atmosphere (CA). Due to their reported high polyphenolic content in the fruit, three varieties of quinces, like Ekmek, Bereczhi and Tinella were stored and monitored for twelve months. During storage period, the following quality parameters were monitored: dry matter content (D.M.%), titratable acidity (TA), soluble solids (°Brix), firmness, antioxidant capacity and also content in total flavonoids and total polyphenols. After twelve months of storage, observations showed that quince from Tinella variety presented better quality parameters compared to quinces from Ekmek and Bereczhi varieties. As expected, keeping quinces in the presence of CO2content, respectively 2% and 5%, presented better physical and biochemical quality compared with those stored without CO2 (control).

Eight anther-derived DH lines of pepper hybrids: two red-fruited (AP14, AP15) and two yellow lines (AP25 and AP32) of <i>C. annuum</i> (ATZ1 × PO)F<sub>2</sub>, two lines of (<i>C. frutescens</i> × <i>C. annuum</i>)F<sub>1</sub> (FA1, FA2), and two of (<i>C. frutescens</i> × <i>C. chinense</i>)F<sub>1</sub> (FCH2, FCH3), were studied regarding important morphological plant and fruit characters. <i>C. annuum</i> breeding line 'ATZ1' was used as a standard. The following traits were evaluated: total fruit yield, fruit weight, weight of placenta with seeds, technological matter, pericarp thickness, extract content, dry matter content, weight and number of seeds per fruit. The level of homogeneity within the DH lines was analysed with a one-way analysis of variance, additionally the values of coefficient of variation (CV) were determined for the tested plant characters. The highest phenotypic uniformity was noted for the red-fruited lines obtained from anthers of (ATZ1 × PO)F<sub>2</sub> and for the DH lines of (<i>C. frutescens</i> × <i>C. annuum</i>) F<sub>1</sub>, while the least uniform were FCH2 and FCH3 lines of (<i>C. frutescens</i> × <i>C. chinense</i>)F<sub>1</sub>. The DH lines AP14 and AP15, as well as FA1 and FA2 were phenotype homogeneous in respect of weight of fruit, technological matter, pericarp thickness and extract content. For these parameters, also the values of CV were the lowest. Statistically significant interline polymorphism between the androgenic lines of the same origin was detected among the lines of <i>C. annuum</i> (ATZ1 × PO)F<sub>2</sub>.
