Does Post-Harvest Losses Matter on Farmers Profitability? Evidence From Smallholder Grape Farmer’s in Dodoma, Tanzania

This study analysed post-harvest losses of grapes and their effects on profitability of smallholder grape farmers in Dodoma. Cross section survey using structured questionnaire was used to collect primary data from 240 grape farmers who were selected through a random sampling procedure. Descriptive statistics, paired t-test, gross margin and multiple regression analysis were used to achieve the objectives of this study. Results show that, the average quantity of grape yields by smallholder grape farmers’ in Dodoma was 7.7 tonnes/ha. Out of these, 1.65 tonnes/ha equivalent to 20.9% of the total grape harvested were lost. Based on multiple regression model, results showed that post-harvest losses have significant effect on the profit of smallholder grape farmers in Dodoma (p<0.01) by 13.9%. The observation is implied by a lower profit with loss (1.8 million/ha) compared to profit without loss (2.9 million /ha) received by farmers’ from the gross margin analysis. The study concludes that a substantial proportion of grapes produced did not reach the final consumers due to post-harvest losses which had significant effect on farmers’ profitability. It is recommended that reduction in post-harvest losses in grape farming should be of utmost priority in any efforts of improving farmers’ profit. These efforts may entail provision of adequate training to farmers on post-harvest losses and handling techniques to create awareness among actors and investing in post-harvest technologies to prolong grapes’ shelf life, reduce post-harvest losses and increase profit of smallholder grape farmers

Storage quality of dehulled split pulses as influenced by packaging material

Efficacy of various packaging materials in preserving split dal of blackgram, redgram, and chickpea was assessed at Post-harvest Technology Centre, Bapatla during 2022-23. No natural infestation by pulse beetle, red flour beetle, or almond moth was detected in GrainPro bags and aluminium pouches even after 90 days of storage. Under artificial infestation, GrainPro bags exhibited adult populations of Callosobruchus maculatus (F.) and Tribolium castaneum (Herbst), as low as 0.33 for blackgram and chickpea dal, with zero infestation observed in redgram dal. Aluminium pouches recorded adult populations of C. maculatus at 0.67 for blackgram, 2.0 for chickpea dal, and zero infestation in redgram dal. GrainPro bags recorded adult populations of T. castaneum at 1.33 for blackgram and chickpea dal, and zero infestation in redgram dal, while aluminium pouches had populations at 1.0 for blackgram, 2.33 for chickpea dal, and zero infestation in redgram dal. GrainPro bags exhibited minimal grain damage (<1.0%) and weight loss (<0.1%), while aluminium pouches also showed negligible levels of grain damage and weight loss (1.0% and 0.12% in blackgram dal, 1.67% and 0.04% in redgram dal, and 0.33% and 0.01% in chickpea dal, respectively). GrainPro bags and aluminium pouches exhibited the lowest levels of fungal growth under both natural (1.0 × 103 CFU/g or slightly more) and artificial infestation (2.0 x 103 to 6.0 × 103 CFU/g) coupled with minimal bacterial growth (0.8x107 to 5.0 × 107 CFU/g under artificial infestation). There was no much deviation in the colour of the products stored in GrainPro bags and aluminium pouches under both conditions, highlighting their superior protective qualities. On the contrary, the woven polymer bag recorded significantly higher adult populations with substantial grain damage and weight loss (4.33% and 0.31% in blackgram dal, 7.7% and 1.15% in redgram dal, and 24.0% and 2.2% in chickpea dal, respectively).

Advances in the Understanding of Postharvest Physiological Changes and the Storage and Preservation of Pitaya.

Highly prized for its unique taste and appearance, pitaya is a tasty, low-calorie fruit. It has a high-water content, a high metabolism, and a high susceptibility to pathogens, resulting in an irreversible process of tissue degeneration or quality degradation and eventual loss of commercial value, leading to economic loss. High quality fruits are a key guarantee for the healthy development of economic advantages. However, the understanding of postharvest conservation technology and the regulation of maturation, and senescence of pitaya are lacking. To better understand the means of postharvest storage of pitaya, extend the shelf life of pitaya fruit and prospect the postharvest storage technology, this paper analyzes and compares the postharvest quality changes of pitaya fruit, preservation technology, and senescence regulation mechanisms.

Forage-cactus based edible coating, packaging, and refrigeration improve the visual and nutraceutical qualities of sweet potatoes

Sweet potatoes have high economic relevance in developing countries. Therefore, the adoption of post-harvest technologies for their conservation for long-distance markets is crucial. In this work, the effect of the combined use of cactus-based edible coating, packaging and refrigeration on the quality of sweet potatoes was evaluated. Four coating and packaging treatments were evaluated: (Control, Coating, Packaging, and Packaging + Coating) and seven storage periods (0, 7, and 14 days at 8 °C, and 17, 20, 23, and 26 days at 23 °C simulate refrigerated transport and shelf conditions respectively). Coating treatments consisted of immersion in 0.04 g L−1 of forage cactus mucilage + 300 mL L−1 glycerol for 1 min. After 14 days of cold storage, sweet potatoes were maintained at 23 °C for up to 26 days. Raw and cooked (microwaved for five minutes) sweet potato samples were evaluated at 0, 7, 14, 17, 20, 23, and 26 days. The refrigerated condition maintained sweet potato quality based on visual analysis for up to 14 days, regardless of the use of the edible coating. However, only packaged sweet potatoes, with or without coating, maintained higher visual scores after transfer to room conditions, exhibiting lower fresh weight loss up to 26 days. Sweet potatoes subjected only to edible coating maintained an acceptable visual appearance until 23 days. Additionally, firmness, visual analysis, DPPH and FRAP antioxidant activity, soluble phenolic and starch contents were more stable in raw and cooked sweet potatoes packaged (with or without coating) for up to 26 days, which is a sufficient time to reach more distant markets.

Evaluation of modified atmosphere packaging system developed through breathable technology to extend postharvest life of fresh muscadine berries.

Muscadine grapes (Vitis rotundifolia Michx.) are delicate in nature with short shelf life. Postharvest technologies like modified atmosphere packaging (MAP) with reduced oxygen (O2) and elevated carbon dioxide (CO2) could increase the postharvest storage life with better quality. In the current experiment, physical and biochemical quality attributes of black and bronze cultivars of muscadine grapes ('Supreme' and 'Granny Val', respectively) were evaluated in active MAP. Fruit were packed in plastic trays, sealed with impermeable film, and CO2 was introduced into the package. The MAP was created by a rigid microperforated plastic patch coated with a proprietary semipermeable resin, which was applied over a hole in the tray; packages with the same size hole without a patch were the control. Fruit were stored at 4°C for 42 days (6 weeks). MAP resulted in significantly lower decay incidence and better retention of fruit firmness for up to 28 days of storage in both cultivars as well as reducing color changes in 'Supreme' fruit. Although MAP did not affect the biochemical quality of muscadine grapes, total antioxidants increased initially and then decreased during storage, irrespective of packaging treatments. A significant linear increase in total phenolic content was also found during storage, regardless of treatments applied. Overall, the results of the current study demonstrate that MAP can be an affective technology to increase storage duration of muscadines with better retention of physical quality, without affecting the biochemical attributes.

Influence of Hibernation and Dehydration on the Hatching Percentage of Artemia Cyst Collected from Solar Saltpan

The brine shrimp Artemia franciscana is an important live feed for fin and shell fish larval culture. Cysts of Artemia are naturally found in a wide variety of harsh environments where they are exposed to different changing environmental conditions. Artemia cysts are also exposed to different hydration/dehydration (H/D) conditions during the post-harvest processing period in the Artemia processing industry. India has enormous quantity of cyst production every year from solar saltpans. But due to the lack of proper post-harvest processing technology, most of the cyst are sold to very low price to larval rearing industries. The aim of the present study was to find out the effect of different rate of dehydration, and different preservation temperatures for enhancing cyst hatchability. The cysts were collected from Thamarikulam saltpan in Kanyakumari District, Tamilnadu, India. The collected cysts were dehydrated to different percentages and preserved at 0º, -10˚ and -20˚C for different durations. The study disclosed that the cyst required 1.3h for full hydration in 30ppt saline water and reached full dehydration at 16h in saturated saline solution. Among the three preservation conditions, the maximum hatching percentage (77.95%) was observed in the cyst that preserved at -20˚C for 400days.Among the different rate of dehydration and hibernation, the 40% dehydrated cyst allowed to hibernate at -20˚C had the maximum hatching percentage. From this study, it is concluded that the optimum of all dehydration percentage, level of chillness and duration of cold storage had equally influenced in the improvement of cyst quality.

It was also observed that the guava RTS and squash retained normal annatto color for eight months, thereafter, both the beverages started showing non-enzymatic browning during storage. The extract of annatto seeds was also found to act as preservative for both the processed products of guava.

Cold atmospheric pressure plasma as eco-friendly technology prolonged the vase life and improved the quality of cut rose flowers

Cold atmospheric pressure plasma is a relatively new technology characterized by safety and high efficiency, that is increasingly attracting attention in agriculture and food industries especially in post-harvest technology. This experiment addresses the potential use of plasma-activated water (PAW) for increment of cut rose flower longevity and quality. A complete randomized design was used in this study, and each treatment had three replicates with six flowers in each replicate. Based on the findings of this study, it seems that PAW application as a preservation solution improves plant water status during postharvest storage and reducing the electrolyte leakage and maintaining the relative water content (RWC). Data from the experiment showed that the plasma activated water decreased the malondialdehyde content and maintains the structure and integrity of the cell membrane through the activation of enzymatic and non-enzymatic antioxidant systems and phenolic compounds synthesis ultimately leading to postharvest quality and prolonged vase life of cut rose flowers. As PAW is more cost-effective than many other preservatives and is eco- friendly with fewer side effects, so it could be used in preservative solutions as an alternative.

Preliminary Analysis, Combined with Omics of Chilling Injury Mechanism of Peach Fruits with Different Cold Sensitivities during Postharvest Cold Storage

The storage of peach fruits at 4–5 °C can easily lead to chilling injury and greatly reduce the quality and commercial value of peach fruits. In this study, two kinds of peach fruits (CX and CM) were selected to analyze the mechanisms of chilling injury in fruits with different chilling sensitivity by means of their lipidomic, transcriptome, and dynamic changes in plant hormones. We found that the ethylene, abscisic acid (ABA), and lipid contents changed differently between CX and CM. The ABA and dilactosyl diacylglycerol (DGDG) contents significantly increased after refrigeration in CM fruit, leading to strong cold resistance. However, low temperatures induced a greater accumulation of ethylene, phospholipids, and ABA-GE in CX fruit than in CM fruit, eventually leading to more severe CI symptoms in CX fruit. Additionally, a transcriptional regulatory network for CM and CX fruits during cold storage was constructed, providing a new theoretical reference for the cultivation of cold-resistant peach cultivars and the development of postharvest preservation technology.
