ABSTRACT This study aimed to evaluate the nutritional quality of Pilosocereus gounellei using different methods of spine removal and plant storage. A total of 600 P. gounellei cacti were randomly selected in 10 hectares of Caatinga. The experimental design was completely randomised using a 2 x 4 factorial arrangement and three replicates. The variables evaluated were the storage conditions (under trees; and ventilated storage facilities) and four types of spine removal techniques assessed 31 days after storage (fresh plants with spines [control]; use of flamethrowers before storage; slash-and-burn [“coivara”] before storage; and use of flamethrowers after storage). The P. gounellei subjected to slash-and-burn during the cladode harvest (cutting) process deteriorated rapidly and exhibited a smooth consistency; dark colour. The burning process resulted in increased in situ degradability of dry matter compared with the control treatment. The results of treatment 4 were similar to those of the control treatment regarding the preservation of the nutritional properties of P. gounellei. Therefore, P. gounellei can be harvested and stored fresh for 31 days without losing their nutritional properties, and spines should be removed using flamethrowers after the storage period, i.e., when using the plants as livestock feed.

n the current paper, we aimed to analyze the way in which packing (different polyethylene types) influence the quality of pasteurized melange during storage, packing being realized in units of 1 kg (Tetra Pak) (batch Lexp-1) and units of 5 kg (Bag in box) (batch Lexp-2). Products were stored during a period of 28 days at a temperature of +4�C, qualitative determinations being realized in first day (day 0), at 7 days, at 14 days, 21 days and in day 28 of storage. Were effectuated a sensorial examination and chemical analysis were was established the content in dry matter (%), water (%), proteins (%), content in essential amino acids (isoleucine, methionine, tryptophan, phenylalanine) and non-essential amino acids (alanine, histidine, glycine, serine) (mg/100g) as well as the content in lipids (%) establishing their profile by identification of some saturated fatty acids (16:0 mg/100g and 18:0 mg/100g) and unsaturated fatty acids (16:1 mg/100g and 18:1 mg/100g). After sensorial examinations, the first modifications were observed at the checking effectuated in day 21 for batch Lexp-2, the obtained score being of 18 points, and at checking effectuated in day 28 was given a score of 18 points for melange belonging to batch Lexp-1 and only 14 points for melange from batch Lexp-2. Differences were recorded also in case of chemical composition of products, so for protein content at batch Lexp-1 in first checking day was obtained a mean of 12.730�0.24% and at batch Lexp-2 12.614�0.22%. Differences between those two batches were insignificant (p[0.05). In case of fat content, at the end of storage period was obtained a mean of 11.256�0.06% for batch Lexp-1 and 11.244�0.11% for batch Lexp-2, differences being insignificant (p [ 0.05). Regarding the profile of amino acids and fatty acids, the mean values obtained during whole storage period oscillated from one stage to another, but the differences between those two batches were insignificant (p [ 0.05). Pasteurized egg melange suffers certain sensorial modifications during storage, especially on consistency and colouring, modifications which are accentuated mainly by storage conditions. Type of polyethylene utilized for this product hadn�t influenced the nutritive qualities of product.

Aims: Evaluate whether mechanical damage and storage conditions affect the quality of the ‘Markies’ potato for processing. Study Design: The experimental design was the completely randomized, in the scheme of split-plots. The plots were composed of treatments with and without mechanical damage and the subplots were made up by the evaluation times, with 5 replicates, where the experimental unit was composed of 2 tubers. Place and Duration of Study: Tubers of the ‘Markies’ cultivar from the producing region of Perdizes, State of Minas Gerais, were planted in June 2016 and harvested in October 2016. Methodology: The tubers were stored for 2 months at 8°C, and further divided into treatment with damage, in which the tubers were subjected to impact and abrasion; and control treatment, in which the tubers were not damaged. After that, they were stored at 28°C and evaluated for their loss of loss of accumulated fresh mass (FML), total soluble sugar (TSS), reducing sugar (RS), non-reducing sugar (NRS) and color after frying in the periods of 0, 12, 24, 36 and 48 h after being placed at room temperature. Results: The mechanical damage in the tubers increased FML, however, it did not affect the content of TSS, NRS, RS and color after frying. Increases were observed in the content of TSS and NRS after 12 h of evaluation. Grade 2 was assigned to the coloring scale after frying for the tubers regardless of treatment or evaluation period. Conclusion: Mechanical damage increases the FML and the ‘Markies’ cultivar is suitable for the industry of pre-fried potato processing even under the occurrence of mechanical damage and exposure to high temperatures.

Until now there are only few data on the effects of thermal treatments on the nutritional and hygienic characteristics of donkey milk. This Research Communication aims to provide information on the effects of pasteurization (at +65 °C for 30 min) and prolonged storage at refrigeration and freezing temperatures (21 d at + 3 °C ± 2 °C and up to 90 d at −20 °C ± 5 °C) on some nutritional and hygienic characteristics of Amiata donkey milk. The milk was monitored by chemical and microbiological analysis. Pasteurization ensured compliance with EC Regulation No 1441/2007, as Enterobacteriaceae were never found in the milk, or during storage at refrigeration and freezing temperatures. Colony count at 30 °C in pasteurized milk never went beyond 1 log CFU/ml. The heat treatment and the storage did not result in any variations in the main constituents of the milk. Only a decrease in lactose and few variations in some fatty acids at 90 d of freezing were observed. In conclusion, pasteurization was able to achieve and maintain a high hygienic-sanitary quality over time; storage at refrigeration or freezing temperatures did not alter the nutritional quality of fat and the gross composition of the product. These findings are useful to improve knowledge on the milk shelf life in order to guarantee safety and nutritional quality for infants who need small quantities of daily milk.

The quality of 'Kensington' mangoes (Mangifera indica Linn.) from 2 major Queensland production regions was evaluated following a hot air [HAT, also known as vapour heat (VHT)] disinfestation treatment (46.5�C seed surface temperature held for 10 min under conditions of high humidity) combined with a disease control treatment (55�C water for 5 min) prior to HAT, and storage conditions likely to be encountered during air shipment to Japan (either 10�C for 5 days plus 22�C for 5 days, or 13�C for 5 days plus 22�C for 5 days, or 22�C for 10 days). Final quality was optimum if fruit were treated with HAT alone and stored at 22�C. Fruit injury, in the form of skin browning and lenticel spotting, was particularly severe in HAT plus disease controI fruit stored at 10/22�C. Storage at 10�C combined with heat treatments may be too stressful to fruit physiology, leading to fruit injury and reduced fruit quality at the market destination.

Aims: Fish is a product more and more consumed in Burkina Faso, especially in Ouagadougou. Poor sale and storage conditions can impact on the hygienic quality of fish. The objective of this study was to identify the contamination risks due to the sale and storage conditions of smoked, dried and fresh fishes. Study Design: A descriptive design was used to identify the different types and origins of fish on the markets in Ouagadougou and the practices and conditions of sale that could be sources of chemical and microbiological contamination. Place and Duration of Study: Relevant data was collated in Ouagadougou (Burkina Faso) from February 2019 to July 2019. Methodology: A survey was conducted among traders of dried and smoked fish from 50 markets and major sales sites in Ouagadougou. Data collection was done using a questionnaire developed with Sphinx Plus2 software. Results: The results indicated a higher proportion of men (75%) than women (25%) with an age between 21 and 45 years old were participated in fish trade. The fish encountered in the markets of Ouagadougou come from Sourou, Kompienga and Bagré, as well as from external suppliers such as Côte d'Ivoire, Mali and Senegal. The different types of fish sold were dried or smoked carp (36.67%), smoked catfish (23.33%), dried Nanani or Djêdjê wala (concorde) (13.33%), smoked Macharon (10%), smoked Racok (10%) and smoked eels or Roolgo in mooré (local language) (6.67%). The types of fish most purchased by consumers, in order, were: Carp, Catfish, Macharon, Nanani. In addition, the study detected risks of contamination of the fish, namely: exposure material consisting of tables and baskets, conservation at room temperature, storage period of 10 to 30 days, no training in hygiene, fish served with bare hands, exposed to dust and stray animals. Conclusion: In sum, the study revealed some characteristics of the fish industry in Ouagadougou and also risks of contamination of fish sold on the markets.

Freshly harvested capsicum has limited shelf life (5-6 days) under ambient storage conditions. The functional quality of capsicum has been assessed in two sizes (300g±10%) and (900g±10%) of 30µ flex freshTM expanded polyethylene biopolymer pouches at 3 and 10oC and 90-95% RH under modified atmospheric storage. In both small and big size pouches, composition of oxygen and carbon dioxide varied from 18.8-19.9% and 18.8-19.4% and from 2.2-0.7% and 2.0-1.4%, respectively during 28 days of storage at 3oC. Positive and significant correlation was observed between overall acceptability and CO2 composition however, negative correlation was observed with O2 composition. Minimum increase (6.02% and 4.35%) in PLW, minimum decrease in firmness (4.71N-3.50N and 4.71N-2.70N), minimum decrease in chlorophyll (70.3% and 75.5%) and minimum losses (47.6% and 40.3%) of ascorbic acid were obtained after 28 days of storage in small and big size capsicum, respectively at 3oC. The decrease in total phenol and antioxidant activity was 82.4% and 78.6% and 60.1% and 59.4%, respectively after 28 days of the storage at 3oC of small and big size capsicum, respectively. Judges observed most acceptable consistency and OAA score for both sizes of capsicum in pouches up to 21 days of storage at 3oC.

During dry seasons, equines are traditionally fed hay. However, if not prepared under favorable climatic conditions and if not properly stored, hay does not preserve its nutritional value. The aim of this research was to evaluate the chemical composition in Stylosanthes guianensis cv. Mineirão and Estilosantes Campo Grande hay varieties, used to feed equines over 225 days of storage. Treatments consisted of Stylosanthes guianensis cv. Mineirão and Estilosantes Campo Grande hay varieties, assessed at six moments of storage: 0, 45, 90, 135, 180, and 225 days. The experiment followed a completely randomized split-plot design. In the comparison between varieties, differences (P0.05) over the 225 days of storage. The storage period had little impact on the nutritional quality of the assessed hays. The Stylosanthes guianensis cv. Mineirão and, mainly, Estilosantes Campo Grande hay varieties have potential to be used in equine diet.

Worldwide, French beans (Phaseolus vulgaris L.), tomato (Solanum lycopersicum L.), and kales (Brassica oleracea L. var. acephala) are considered economically important food crops. There is a rapid decline in their yield due to severe soil degradation. Thus, high commercial fertilizer inputs are crucial, though they remain expensive and inaccessible to resource poor farmers. We investigated the comparative performance of composted black soldier fly frass fertilizer (BSFFF), conventionally composted brewer's spent grain (BSG), commercial organic fertilizer (Evergrow), and mineral [nitrogen, phosphorus, and potassium (NPK)] fertilizer on growth, yield, N use efficiency, and nutritional quality (crude protein, crude fiber, crude fats, ash, and carbohydrate concentrations) of tomatoes, kales, and French beans under greenhouse and open-field conditions for two seasons. The fertilizers were applied at rates equivalent to 371 kg of N ha−1. For each crop, the plots were treated with sole rates of BSFFF, BSG, Evergrow, and NPK to supply 100% of the N required. Additional treatments included a combination of BSFFF and NPK, and BSG and NPK so that each fertilizer supplies 50% of the N required. The control treatment consisted of unfertilized soil. Results show that vegetable yields achieved using a combination of BSFFF and NPK were 4.5, 2.4, and 5.4-folds higher than the yield from the control treatment for tomatoes, kales, and French beans, respectively. The combined application of BSFFF and NPK produced 22–135%, 20–27%, and 38–50% higher yields than sole NPK for tomatoes, kales, and French beans, respectively, under both greenhouse and open-field conditions. The highest agronomic N use efficiency was achieved in sole BSFFF-treated plots compared to sole BSG and Evergrow. The N taken up by the vegetables was significantly higher when BSFFF and NPK were integrated. Vegetables grown using a combination of BSFFF and NPK had the highest crude protein and ash concentrations. Our findings demonstrate that the integration of BSFFF and NPK in vegetable cropping systems at the recommended rate of 1.24 t ha−1 BSFFF and 322 kg ha−1 NPK would improve soil health, boost yield, and nutritional quality of vegetable crops.
