Research Progress on Methods for the Deacidification of Small Berry Juice: An Overview

As some of the richest sources of natural antioxidants, small berry fruits have attractive colors and special tastes, with recognized benefits for human health. However, sour tastes in small berry juices result in a poor flavor and low acceptance among consumers, greatly limiting their marketability. Among the most commonly used deacidification methods, chemical deacidification methods can neutralize fruit juice via the addition of a deacidification agent, while physical deacidification methods include freezing deacidification, ion-exchange resin deacidification, electrodialysis deacidification, and chitosan deacidification. All of these methods can markedly improve the pH of fruit juice, but they introduce new substances into the juice that may have an influence on its color, taste, and stability. Biological deacidification can effectively remove malic acid from fruit juice, reducing the content from 15 g/L to 3 g/L; additionally, it maintains the taste and stability of the juice. Therefore, it is widely applied for fruit juice deacidification. On this basis, some compound deacidification technologies have also emerged, but they also present problems such as high costs and complicated working procedures. This review of deacidification methods for small berry juice provides a foundation for the industrial development of such juices.

Biogeography of Zehneria (Cucurbitaceae) and a New Species from India

Abstract— Zehneria is one of the most diverse genera in Cucurbitaceae with 75 accepted species mainly in Southeast Asia and tropical Africa. Here, we describe Zehneria neorensis, a new species from Neora Valley in the mountains of West Bengal, India, which has 7‐10 cm long twisted fruiting pedicels, the longest pedicels reported in the genus so far. Based on morphological data, we also suggest the transfer of Melothria morobensis to the genus Zehneria. With a molecular phylogenetic and global biogeographic analysis based on 3856 nucleotides of plastid and nuclear ribosomal DNA, we demonstrate that the genus Zehneria most likely originated on the African continent 24 (30‐19) million years ago and spread from there at least five times to Madagascar and three times to Asia. Zehneria neorensis represents an independent colonization event from Africa to India about 11 (15‐7) million years ago. Three lineages reached New Guinea/Australia and finally moved into Polynesia. We infer a rate of at least 20 long-distance dispersal (LDD) events per 10 million years in the genus. This high LDD frequency is most likely a result of the small berry fruits and small flattened seeds of Zehneria, which seem perfectly adapted to long-distance bird dispersal. Field observations are needed to investigate a potential effect of the newly discovered extended and coiling pedicels in Zehneria neorensis on seed dispersal efficiency. The new species adds to a growing list of rather old Cucurbitaceae lineages in the Himalayan foothills, supporting the hypothesis of long climatic stability in the region.

The complete chloroplast genome of highbush blueberry (Vaccinium corymbosum)

Highbush blueberry is a small berry fruit tree belonging to the family Ericaceae and genus Vaccinium, which fruit has high nutritional value. High-throughput sequencing technology was applied in this study to sequence and assemble the whole chloroplast genome of the southern highbush blueberry variety sharpblue. The results of the study showed that the circular genome of sharpblue is 170,737 bp in length, and the GC content of the genome was 36.8%. The complete chloroplast genome of sharpblue has consisted of two inverted repeat regions (IRs), a large single-copy region (LSC, 31, 076 bp), and a small single-copy region (SSC, 3, 044 bp). The chloroplast genome contained a total of 144 functional genes, including 100 mRNA genes, eight rRNA genes, and 36 tRNA genes. In addition, V. corymbosum and V. oldhamii were clustered into one group in this phylogenetic analysis which indicated that they have a close evolutionary relationship. The findings of this investigation are a significant reference source for the phylogeny and evolutionary origin of the Ericaceae family.

Effect of modified atmosphere packaging (MAP) and gaseous ozone pre-packaging treatment on the physico-chemical, microbiological and sensory quality of small berry fruit

• Comparison of ozone-MAP technology on three small berry fruit quality. • Ozone-MAP technology improves small berry fruit microbial quality. • Main physico-chemical parameters are not affected by ozone pre-treatment. • Ozone-MAP treatment preserved total and individual anthocyanins in blueberries. The aim of this work has been to evaluate the combined effect of modified atmosphere packaging (MAP), and a gaseous ozone pre-treatment on the main microbiological and chemical parameters of strawberries, raspberries and blueberries during cold storage. The three types of small fruit were exposed to 13 mg m −3 of gaseous ozone (about 6 ppm) for 16 h at 1 °C (±0.5 °C) and then stored for 15 d under MAP (10 kPa O 2 and 40 kPa CO 2 ) or in air at 4 °C. The combined technology determined a significant (P ≤ 0.05) reduction of the yeast and mould counts, compared to samples stored in air and MAP without any pre-treatment. The main quality parameters of the three types of fruit were not affected by combined ozone pre-treatment and MAP storage. The combined effects of ozone and MAP led to a better preservation of the total and individual anthocyanins in the blueberries during cold storage. In conclusion, the exposure to gaseous ozone before packaging followed by storage under MAP could be a useful technological approach to extend the postharvest storage of small berry fruit.

Identification of Small Berry Species in Food and Juice Using TaqMan-Based Real-Time PCR

Abstract Background: Public interest is growing for small berries in recent years because they are very delicious, low in energy, and full of bioactive compounds with potential health benefits. Similar to other food products, adulteration of small berry fruit products poses economic and safety problems to consumers. Objective: To protect consumers and regulate the small berry fruit products market, it is necessary to establish a robust method for detecting the authenticity. Methods: In this study, TaqMan-based real-time PCR assay was established for species identification of cranberry, raspberry, and blueberry to ensure authenticity of commercial small berry food products (pulp, dried fruit, fruit juice, jam, and puree). Results: Absolute detection limit was 0.1 pg/μL DNA for raspberries, 1 pg/μL DNA for blueberries, and 10 pg/μL DNA for cranberries. Practical LOD was 0.1% (v/v) for fresh juice. For processed juice, practical LOD was 1% for blueberry and red raspberries, 0.1% for black and yellow raspberries, and 5% for cranberry. Conclusions: The method was shown to be functional and effective to detect the raw material composition of cranberry, raspberry, and blueberry for commercial products. Highlights: TaqMan probe-based real-time PCR methods were designed to identify three small berries (blueberry, raspberry, and cranberry) in berry products. Efficient DNA recovery methods and detection strategy were established to ensure correct and sensitive testing of fresh small berries exhibited a detection limit of 0.1 to 10 pg/μL. The practical minimum detection levels were 0.1 to 5% in fresh and processed juice, including pasteurization and HTHP.

Authentication of Small Berry Fruit in Fruit Products by DNA Barcoding Method

Small berry fruit products are gaining an expanded market due to their high nutrition value. However, the authenticity of products is challenged by adulteration and mislabeling. To establish an accurate and robust method for identifying both known and unknown fruit species in small berry fruit products, DNA barcoding technology based on Sanger sequencing was adopted. To overcome the influence of processing conditions on DNA recovery, mini-barcodes of rbcL and ITS and a medium-barcode of psbA-trnH were applied. To identify ingredients in products containing mixed species, plasmid cloning was applied to separate mixed barcodes. The method established in this paper could detect 1% to 10% target species in mixed fruit juice.

Developmental inhibition of Drosophila suzukii by ionizing radiation

AbstractSpotted wing drosophila (SWD) has emerged as a major invasive insect pest of small berry fruits in the Americas and Europe since the late 2000s. Thus, phytosanitary treatment of commodities for export is imperative to prevent the movement of viable SWD to newer areas. In the present study, all developmental stages of SWD were irradiated with different doses of gamma and electron beam radiation to assess developmental inhibition to identify potential quarantine doses of the radiations. Ionizing radiation induced developmental inhibition of all stages of SWD. The effective doses for 99% inhibition (ED99) of hatching, pupariation, and adult emergence from irradiated eggs for gamma radiation were 882, 395 and 39 Gy, respectively, compared with 2849, 687, and 41 Gy, respectively, for electron beam radiation. The ED99 for inhibition of pupariation and adult emergence in irradiated larvae were 703 and 47 Gy, respectively, for gamma radiation, and 619 and 33 Gy, respectively, for electron beam radiation. Pupal irradiation did not completely inhibit adult emergence, even at 300 Gy. However, irradiation with ≥100 Gy of puparia induced adult sterility, with no egg production at all. The ED99 for inhibition of F1 egg hatchability from adults irradiated with gamma radiation and electron beam radiation was estimated to be 424 and 125 Gy, respectively. The results of the present study suggest that gamma radiation and electron beam radiation are alternatives for phytosanitary treatment. Irradiation with 100 Gy could be suggested as a potential dose for egg, larval, and pupal quarantine treatment of SWD.

Comparative Analysis of Fruit Ripening-Related miRNAs and Their Targets in Blueberry Using Small RNA and Degradome Sequencing.

MicroRNAs (miRNAs) play vital roles in the regulation of fruit development and ripening. Blueberry is an important small berry fruit crop with economical and nutritional value. However, nothing is known about the miRNAs and their targets involved in blueberry fruit ripening. In this study, using high-throughput sequencing of small RNAs, 84 known miRNAs belonging to 28 families and 16 novel miRNAs were identified in white fruit (WF) and blue fruit (BF) libraries, which represent fruit ripening onset and in progress, respectively. Among them, 41 miRNAs were shown to be differentially expressed during fruit maturation, and 16 miRNAs representing 16 families were further chosen to validate the sRNA sequencing data by stem-loop qRT-PCR. Meanwhile, 178 targets were identified for 41 known and 7 novel miRNAs in WF and BF libraries using degradome sequencing, and targets of miR160 were validated using RLM-RACE (RNA Ligase-Mediated (RLM)-Rapid Amplification of cDNA Ends) approach. Moreover, the expression patterns of 6 miRNAs and their targets were examined during fruit development and ripening. Finally, integrative analysis of miRNAs and their targets revealed a complex miRNA-mRNA regulatory network involving a wide variety of biological processes. The findings will facilitate future investigations of the miRNA-mediated mechanisms that regulate fruit development and ripening in blueberry.

Antioxidant potential in selected species of small berry fruits

In our research, the antiradical activity (% inhibition DPPH) as quality indicator of selected species of small berry fruits were observed. The analysis of their antiradical activity have shown that the highest values of inhibition of DPPH were found in blueberry ( Vaccinium corymbosum L.) (78.95 %) and lingonberry ( Vaccinium vitis-idaea L.) (68.89 %). The lowest values were found in bilberry ( Vaccinium myrtillus L.) from area Stara Ľubovňa (50.54 %) and red currant (Ribes rubrum L.) (51.51 %). Between all selected species were recorded statistically significant difference (P < 0.01). Generally, small berries are consumed because of their attractive colour and special taste. The objective of this research is to highlight on their the health benefits because are considered one group of the richest sources of natural antioxidants with higher antiradical activity.

Volatile aroma and sensory analysis of black raspberry wines fermented by different yeast strains

Robus coreanus Miquel is a small berry fruit used for Korean black raspberry (KBR) wine-making. Twelve different yeast strains were investigated by laboratory-scale fermentation to develop a wine with a high flavour quality. Volatile aroma compounds from the wines were analysed using headspace–solid phase microextraction–gas chromatography–mass spectrometry and sensory evaluation was performed to evaluate the flavour characteristics. The volatile aroma compounds that mostly contributed to the flavour of KBR wines were those related to fruity (esters) and floral (terpenes) aromas. Fifteen out of the 67 identified volatile compounds showed higher odour activity values than other compounds in the wines, and these compounds were considered as important contributors to the final aromas of the wine. Additionally, the KBR wine fermented by the M1 yeast strain had the highest sensory preference because of higher fruity and floral aroma characters compared with other wines. In addition to the M1 strain, the other yeast strains that produced favourable sensory characteristics included Enoferm CSM, Uvaferm VRB, Lalvin ICV GRE, Lalvin ICV Opale and LevureSeche Active. Of these strains, the M1 strain produced a particularly excellent black raspberry wine, and thus could be applied for further large-scale production of black raspberry wines. It is also expected that this work will expedite research on the production of high-quality black raspberry wines with beneficial physicochemical properties, functionality and good sensory characteristics.

Anticancer Properties of Bioactive Compounds of Berry Fruits - A Review

An overwhelming body of research has now firmly established that the dietary intake of berry fruits has a positive and profound impact on human health, performance, and disease. Evidence suggests that edible small and soft-fleshed berry fruits may have beneficial effects against several types of human cancers. Studies show that the anticancer effects of berry bioactives reduce and repair damage resulting from oxidative stress and inflammation. In addition, also regulate carcinogen and xenobiotic metabolizing enzymes, various transcriptions and growth factors, inflammatory cytokines, and subcellular signaling pathways of cancer cell proliferation, apoptosis and tumor angiogenesis. Berry phytochemicals may also potentially sensitize tumor cells to chemotherapeutic agents by inhibiting pathways that lead to treatment resistance, and consumption may provide protection from therapy-associated toxicities. This paper is a comprehensive review of the effects of phytochemicals present in berry fruits on cancer and encompasses the occurrence and bioavailability of these compounds evidences for their effects on the various mechanisms by which may exert their effects. These include effects on cellular differentiation and apoptosis; effects on proteins and enzymes that are involved in these processes Review Article Castro and Teodoro; BJMMR, 6(8): 771-794, 2015; Article no.BJMMR.2015.252 772 at a molecular level, and other various effects through altered immune function and chemical metabolism.

Berry antioxidants: small fruits providing large benefits

Small berry fruits are consumed because of their attractive colour and special taste, and are considered one of the richest sources of natural antioxidants. Their consumption has been linked to the prevention of some chronic and degenerative diseases. The term 'berry fruits' encompasses the so-called 'soft fruits', primarily strawberry, currants, gooseberry, blackberry, raspberry, blueberry and cranberry. The objective of this review is to highlight the nutraceutical value of berries and to summarize the factors affecting berry fruit antioxidants. Particular attention is given to postharvest and processing operation factors that may affect fruit phytochemical content. The structure-antioxidant relationships for phenolic compounds - the main group of antioxidants in this fruit group - are presented and major areas for future research are identified.

Berry Fruits for Cancer Prevention: Current Status and Future Prospects

Overwhelming evidence suggests that edible small and soft-fleshed berry fruits may have beneficial effects against several types of human cancers. The anticancer potential of berries has been related, at least in part, to a multitude of bioactive phytochemicals that these colorful fruits contain, including polyphenols (flavonoids, proanthocyanidins, ellagitannins, gallotannins, phenolic acids), stilbenoids, lignans, and triterpenoids. Studies show that the anticancer effects of berry bioactives are partially mediated through their abilities to counteract, reduce, and also repair damage resulting from oxidative stress and inflammation. In addition, berry bioactives also regulate carcinogen and xenobiotic metabolizing enzymes, various transcription and growth factors, inflammatory cytokines, and subcellular signaling pathways of cancer cell proliferation, apoptosis, and tumor angiogenesis. Berry phytochemicals may also potentially sensitize tumor cells to chemotherapeutic agents by inhibiting pathways that lead to treatment resistance, and berry fruit consumption may provide protection from therapy-associated toxicities. Although a wide variety of berry fruits are consumed worldwide, this paper focuses on those commonly consumed in North America, namely, blackberries, black raspberries, blueberries, cranberries, red raspberries, and strawberries. In addition, a large body of studies on singly purified berry bioactives is available, but this paper focuses on studies of "whole berries" per se, that is, as berry extracts and purified fractions, juices, and freeze-dried powders. Potential mechanisms of anticancer action and bioavailability of berry phenolics, as well as gaps in knowledge and recommendations for future berry research, are also briefly discussed.

Evolution of aroma compounds of murtilla fruits (Ugni molinae Turcz) during storage

AbstractBACKGROUND: ‘Murtilla’, ‘mutilla’ or ‘murta’ (Ugni molinae Turcz) is a native Chilean species that produces a small berry fruit with a special aroma, whose volatile compounds have not yet been identified. The fruit may be consumed raw and also as jams, juice, canned products, confections and liquor.RESULTS: At the beginning and end of the storage, 24 volatile compounds were identified in murtilla fruit aroma and the concentration of these compounds in murtilla fruit ranged from 1.2 to 250.5 µg kg−1 fresh weight. Methyl 2‐methyl butanoate, ethyl butanoate, ethyl 2‐methyl butanoate, methyl hexanoate, ethyl hexanoate, methyl benzoate and ethyl benzoate were the major components, all of which have been reported as potent odors in other aromatic fruits. Based on estimated odor activity value, the most potent compound in the murtilla fruit aroma were ethyl hexanoate and 4‐methoxy‐2,5‐dimethyl‐furan‐3‐one. The statistical analysis showed that the storage produced a distinct effect on the same volatile compounds released from the murtilla ecotypes.CONCLUSION: The volatile compounds identified in murtilla fruit aroma, which may be described as fruity, sweet and floral, have been found in other aromatic fruits. Concerning the aroma, the murtilla fruit from ecotype 19‐1 was shown to be the best in cooled storage. Copyright © 2007 Society of Chemical Industry

First Report of Gray Mold Disease of Sponge Gourd (Luffa cylindrica) Caused by Botrytis cinerea in Taiwan.

A disease of sponge gourd (Luffa cylindrica (L.) Roem., family Cucurbitaceae) has become a serious threat to sponge gourd production since 2003 in central Taiwan. Initially, symptoms appear as small, brown spots on the flower petals that spread to the entire flower and cause blossom blight within 2 to 3 days. Subsequently, the pathogen develops abundant mycelium and moves from the petals onto the fruits causing blossom end rot and fruit stem rot. Severely infected fruits become completely rotten and desiccate. Tissues were excised from diseased sponge gourd fruits (sampled from Fongyuan, located at 24.25°N, 120.72°E in Taichung County), immersed in a solution containing 3% sodium hypochlorite and 70% ethanol for 1 min, washed three times with sterile water, and then cultured on potato dextrose agar (PDA) medium. A fungus, identified as Botrytis cinerea, produced abundant mycelium on PDA medium when incubated under constant fluorescent light 185 ± 35 μE·m-2·s-1 at 24°C. The conidia were smooth, hyaline, and globoid or slightly ellipsoid. The conidia measured 9.5 to 19.3 μm (average 13.8 μm) long and 6.0 to 17.8 μm (average 10.1 μm) wide, dimensions that are similar to the descriptions of B. cinerea (11 × 11 to 15 μm) that causes gray mold of strawberry (2). The identity of B. cinerea was also confirmed by the production of numerous black sclerotia on PDA plates incubated either in the dark or under light at 20 to 24°C for 9 to 10 days. Koch's postulates were fulfilled by using 3-day-old mycelial agar discs of the fungus or a spore suspension containing 105 conidia per milliliter of distilled water as inoculum. Shallow (2 × 2 × 2 mm) incisions were made on fresh sponge gourd fruits with a sterile scalpel and inoculated with either a 5-mm mycelial disc or 0.5 ml of the spore suspension. Inoculated areas were covered with moist sterile cotton, and the fruits were enclosed in a plastic bag and incubated at 20 to 24°C for 3 days. Wounded fruits inoculated with PDA discs or sterile distilled water alone served as controls. Pathogenicity tests were performed three times using five fruits in each trial. Symptoms and signs of the disease similar to those described above were observed in all (100%) the inoculated fruits, while no symptoms developed in the control fruits. Reisolation from the inoculated fruits consistently yielded B. cinerea. Reciprocal inoculations on sponge gourd, guava, and strawberry with mycelial discs or spore suspensions of a B. cinerea isolate obtained from sponge gourd, guava, and strawberry showed cross pathogenicity among isolates and hosts. Important groups of plants that are attacked by B. cinerea are vegetables, small berry fruits, ornamentals, and bulbs (1). Though 80 species of host plants, mostly shrubs and nursery plants, were reported to be the host of B. cinerea in Taiwan (3), to our knowledge, this is the first report of gray mold disease affecting sponge gourd in Taiwan.

Anti-inflammatory activity in skin by biomimetic of Evodia rutaecarpa extract from traditional Chinese medicine

Wu-Zhu-Yu, is an extract prepared from the small berry fruit of Evodia rutaecarpa and is reported to have anti-inflammatory and anti-nociceptic activity. Methyl nicotinate (MN) is known to induce the release of PGD(2) resulting in localized erythema within 30 min after topical application to human skin. The purpose of this study was to determine if a defined biomimetic mixture of components of Evodia fruit extract inhibit inflammation in human cells and skin. In order to control the potency of the test article, we prepared a defined biomimetic mixture of synthetic and natural forms of the active components of Evodia fruit extract, containing rutaecarpine, dehydroevodiamine, and evodin. This was tested for anti-inflammatory activity in UVB-irradiated cultured cells and in the MN model of micro-inflammation in human skin. This Evodia biomimetic mixture was a potent inhibitor of UVB-induced PGE(2) released by keratinocytes in culture. We found that MN also induces release of nitric oxide from cultured keratinocytes and microvascular endothelial cells. Twice daily application of 0.1-1% Evodia biomimetic mixture for 2 weeks significantly inhibited erythema after a MN challenge. A single application of 1% Evodia biomimetic mixture also significantly inhibited MN-induced erythema when applied at 60 min before, or within 5 min after MN exposure. The Evodia biomimetic mixture was significantly more effective at inhibiting erythema than bisabolol, the active component of chamomile. These results demonstrate that compounds found in E. rutaecarpa (including the indole quinazoline alkaloids) have powerful anti-inflammatory activity when applied topically to human skin.

Detection of Adulteration in Fruit Juices by Qualitative Determination of Carbohydrates by Gas-Liquid Chromatography

Abstract Sugars and sorbitol in fruit juices can be separated readily by a simple GLC procedure. All fruits show a major fructose peak, followed by 2 smaller glucose peaks. Cherry, plum, apple, and pear also contain sorbitol, which appears between the 2 glucose peaks. None of the small berry fruits contains any sorbitol. The larger fruits, such as apple and pear, also have sucrose, which may occur only as traces in the small fruits. Authentic fruits, as well as many commercial samples, have been examined and the characteristic profiles of the various groups verified. Fruits from various countries, as well as different varieties, exhibit identical patterns. Several commercial concentrates that were judged to be adulterated on the basis of abnormal sugar patterns were also tested by other methods; results confirmed the presence of foreign material. Collaborative studies on 4 samples were conducted and all 9 collaborators reported correct results. The method is recommended for adoption as official first action.
