Introduction. Black plum (Vitexdoniana) is an indigenous fruit tree species importantfor the livelihoods of rural populations. Currently, there is renewednational and international interest in black plum, and it has emergedas a priority species for domestication in Africa. The present workaddressed farmers’ indigenous knowledge of the use and managementof the species among different socio-cultural groups in Benin, takinginto account gender differences. The specific objective of thiswork was to study the knowledge, uses, local gathering practices andmanagement systems of V. doniana that are partof the traditions of the communities in Southern Benin. Materialsand methods. A total of 150 participants randomly selected fromthree socio-cultural groups provided survey responses. Information collectedmainly referred to the motivation of respondents to conserve blackplum trees on their land, the local uses and the management practicesto improve the regeneration and production of the black plum. Resultsand discussion. The study showed that knowledge of black plumis well distributed in the community. However, people have differentinterests in using black plum and there is variable knowledge ofuse and management practices. The food and medicinal categorieswere the most important uses. There were no significant differencesin knowledge of the management and utility of black plum betweenmen and women, or across socio-cultural groups. Conclusion. Givenits value to the communities in southern Benin, black plum should beprioritized for domestication.

Introduction. Natural beveragesface strong competition from synthetic drinks in the open market.Creation of diversity in natural products is a key strategy to withstandthis competition. Pummelo (Citrus grandis Linn.)is one such potential fruit which could be exploited on a commercialscale if processed properly. The bitterness of pummelo juice isa serious handicap in its utilization. The present study aimed atpreparation of a cost-effective, palatable blended beverage of pummelo. Materials and methods. To overcome this problem, pummelowas blended with mango ginger and kokum juice in the ratio of [65:30:5]for the preparation of syrup. The product was stored for 120 daysin ambient conditions of storage and analyzed for changes in itsphysicochemical constituents. Results and discussion.Total soluble solids and total sugar increased during storage, whiletitratable acidity and ascorbic acid content decreased slightlyduring storage. Organoleptically, the best recipe was 25% juice,70 °Brix total soluble solids and 1.5% acidity with a score of 6.3out of 7.0 for overall acceptability. Mango ginger juice suppressedthe bitter aftertaste of pummelo juice and imparted its characteristictaste and flavor to the product. The product was shelf-stable andhad important medicinal constituents in it. The [total revenue / totalcost] ratio of the product was 2.90.

Introduction. Plum cv. SantaRosa shows climacteric behaviour and grows profitably under sub-temperateconditions in India. After ripening, it has a very limited shelflife (3–4 days) in ambient conditions [(38 ± 2) °C and at (68 ± 4)%RH]. Hence, there is an urgent need to extend its marketabilityusing recent techniques. Materials and methods. Plumswere harvested at the pre-climacteric and climacteric stages ofmaturity and packed with newspaper shreds (control), KMnO4-impregnatedchalks, KMnO4-impregnated newspaper shreds or ethylene-absorbent sachets;then they were transported by road to New Delhi. The biochemicaland physiological analyses were carried out at 3-day intervals onplums stored in supermarket conditions [(20 ± 1) °C and at (90 ± 2)%RH] for 15 days. Results and discussion. Untreatedfruits had less firmness than those which were packed with ethyleneabsorbents. The activities of fruit-softening enzymes such as lipoxygenase(LOX), polygalacturonase (PG) and pectin methylesterase (PME) increasedrapidly in the control treatment in comparison with plums packed withvarious ethylene absorbents, the least being either with ethylene-absorbentsachets or with KMnO4-impregnated newspaper shreds. Plums of pre-climacteric andclimacteric maturity attained respiration and ethylene evolutionpeaks on the 9th day and 6th day, respectively. Conclusions. Theplums of pre-climacteric and climacteric stages of maturity packed withethylene-absorbent sachets showed the best results in supermarketconditions in maintaining the firmness, quality and shelf life ofplum up to the 12th day and 9th day of storage, respectively.

Introduction. Cashew appleis a rich source of sugars, vitamin C and polyphenols. In spiteof its nutritional value, this pseudo-fruit has been left unexploitedto a large extent in the crop-growing areas. Some reports of thechemical characteristics of cashew apple have been published. However,nothing is known about the changes in the composition of its bioactive compoundsin the course of ripening. Materials and methods. Cashewapples at three different maturity stages were examined with respectto their ascorbic acid content, phenolic compounds and antioxidantcapacity. Ascorbic acid was quantified by HPLC. Phenolic compoundswere identified and quantified by using HPLC-ESI-MS/MS by comparisonwith authentic standard compounds. The antioxidant capacity wasmeasured by TOSC assay against peroxyl radicals and peroxynitrite. Results. Amounts of identified phenolic compounds werethe highest in unripe cashew apple and decreased in the course ofripening. Myricetin 3-O-rhamnoside, quercetin 3-O-galactoside and quercetin3-O-rhamnoside turned out to be the main flavonoids in all maturitystages. The antioxidant capacity and the concentration of ascorbicacid increased in the course of ripening. The antioxidant activitywas considerably influenced by ascorbic acid, more than by the content ofphenolic compounds. Conclusion. This study provides, forthe first time, information on changes in bioactive compounds andthe antioxidant capacity in cashew apple during ripening. A dietaryor technological exploitation of ascorbic acid is useful in theripe condition. The unripe pseudo-fruits are a good source for the extractionof polyphenols with regard to possible food technological purposesor the preparation of food supplements.

Introduction.Peach brown rot caused by the fungus Monilinia fructicola is a major disease leadingto considerable economic loss during storage. Our previous studyuncovered the striking inhibition of the natural alkaloid berberineagainst M. fructicola. Materials and methods.A berberine-chitosan composite membrane (BCCM) able to slowly releaseberberine was prepared and used for peach preservation. The examinedfruits were stored at 4 °C and treated as follows: (I) control fruits withoutpackaging; (ii) fruits that were transiently immersed in pre-solidifiedBCCM liquid and taken out; (iii) fruit coating either with a BCCM,or with a membrane containing chitosan only (without berberine),and (iv) fruit coating with a PVC membrane. Results and discussion.The group immersed in BCCM showed a high infection rate due to thecytotoxicity of acetic acid, but the coating group showed only a10% infection rate after 40 days of storage. Moreover, the BCCM-coatinggroup showed a significantly lower infection rate than that coatedwith chitosan membrane (without berberine), clearly indicating theantimicrobial activity of berberine therein. Consequently, packedin BCCM and stored at 4 °C, peach fruits could be well preservedover 40 days with very low infection. Conclusion. Consideringits safety and low cost, the berberine-containing chitosan composite membranecould be applicable in controlling diseases during peach storage.

Introduction. Sweet cherryfruit is a very perishable commodity, because fruits decay and losewater rapidly after harvest as a consequence of their high respiratoryrate. The objective of the present study was to evaluate the effectof the combination of hot water plus essential oil treatments andhot water treatment alone on the quality of ‘0900 Ziraat’ sweetcherries during cold storage. Materials and methods.Fruits were divided into four groups and were treated by dippinginto water at 24 °C for 30 s (control), dipping into water at 60 °Cfor 30 s, and dipping into water at 60 °C for 30 s plus either mentholtreatment or thymol treatment. After treatments, all fruits werepacked in polypropylene bags and stored at 0–1 °C temperature and90–95% relative humidity for 45 days. Physical and chemical changeswere determined at 15-day intervals during storage. Resultsand discussion. All of the postharvest treatments improvedfruit quality characteristics compared with fruit of the control.According to the data, after 45 days of storage, combination treatments were found to be more effectivein controlling decay. The treated fruits had higher total anthocyaninand total phenolic compounds. In control fruits, total anthocyanin andtotal phenolic compounds initially showed a slight increase, buttheir accumulation significantly decreased with time.
