“…For example, 'Rose Pearl' and 'Ruby Sweet' were released by National Agriculture and Food Research Organization (Abe et al, 2017;Okada, 2014). In addition to such redfleshed type (type 2), another type (type 1) of redfleshed apples has been also reported, in which type 1 apples show red coloration not only in the whole fruit including skin, flesh, and core but also in the leaves 350 g, with approximately 13°Brix and 0.9% acidity (Matsumoto et al, 2016). The prominent feature is its pinkish flesh color attributed to the anthocyanin content (a kind of polyphenol).…”

“…The prominent feature is its pinkish flesh color attributed to the anthocyanin content (a kind of polyphenol). Although polyphenols usually have a bitter taste, 'Kurenainoyume' has a sweet and mild tart taste without astringency, irrespective of table or processing usage (Matsumoto et al, 2016). Due to its flesh pigmentation and sweetness, it has received greater focus in applications for processing (e.g., for juice, jam, dry fruit, pie, and tart production) by several companies (Matsumoto, 2017) in addition to table usage.…”

Effects of Low Temperature, Shading, Defoliation, and Crop Load on the Flesh Coloration of the Type 2 Red-fleshed Apple ‘Kurenainoyume’

et al. 2018

Kurenainoyume' is a newly released type 2 red-fleshed apple with pinkish flesh color. In our previous study, we revealed the effects of light condition on red coloration of the skin, flesh, and core of 'Kurenainoyume' apple fruit. In this study, we investigated the effects of temperature, shading, defoliation, and crop load on red coloration of the flesh. Low temperature improved flesh coloration; apples subjected to cooling treatment at 5°C or 10°C showed higher a* values of the Lab color space than the control (without cooling treatment), in a temperature-dependent manner. Low temperature reduced the soluble solid content to a lesser extent in some years, whereas fresh weight, malic acid content, and flesh firmness were not affected. Thus, the importance of temperature for flesh coloration was confirmed, similar to its effect on skin coloration. When the trees were covered with cheesecloth with a 50% shading rate from August 1 (82 days after full bloom: DAFB) to October 28 (170 DAFB), flesh coloration was negatively affected, and fresh weight, soluble solid, and malic acid contents were reduced relative to the control treatment (without shading). We also investigated the effects of defoliation (one-seventh of the control) and crop load (two-or threefold the crop load of the normal case control) on flesh coloration. Both defoliation and over crop load also decreased a* values, but their effects on the parameters related to fruit quality were not clear. Because all the treatments of shading, defoliation, and crop load relate to the efficiency of photosynthesis and the distribution of photosynthetic assimilates, our results also demonstrated that photosynthetic assimilates (carbohydrates) were one of the crucial factors affecting flesh coloration.

“…'Kurenainoyume' is a new red-fleshed apple cultivar, which was released in 2010 by Hirosaki University (Igarashi et al, 2011). 'Kurenainoyume' has a flat fruit shape, dark red skin like 'Jonathan', pink flesh, and the average fruit weight is 350 g. The soluble solid content is about 13% and the titratable acidity is about 0.9%, resulting in a sweet, mildly tart taste, that is not astringent either fresh or cooked (Matsumoto et al, 2016). Because of consumers' interest and acceptance of this cultivar, the cultivation areas of 'Kurenainoyume' have rapidly expanded in the northern Tohoku region (northernmost three Prefectures of Honshu Island, Aomori, Akita, and Iwate) in Japan (Matsumoto, 2017).…”

Sunlight Differentially Affects the Fruit Skin, Flesh, and Core Coloration of the Type 2 Red-fleshed Apple ‘Kurenainoyume’: Optimization of Fruit Bagging Treatment

et al. 2018

We investigated the effect of fruit bagging treatment using three kinds of paper bags differing in light permeability on the red coloration of skin, flesh, and core in type 2 red-fleshed 'Kurenainoyume' apples by comparison with type 1 'Goshogawara' apples. Skin coloration of both 'Goshogawara' and 'Kurenainoyume' was affected by light and the effect was more marked in 'Kurenainoyume' than 'Goshogawara'. In contrast, the effect of fruit bagging treatment on the red coloration of the core was limited in 'Goshogawara', while core coloration was not observed in 'Kurenainoyume' type 2 apples. Flesh coloration was observed even under dark conditions in both cultivars, and the light tended to enhance the flesh coloration to some extent in both cultivars. Since fruit bagging treatment is a prerequisite for 'Kurenainoyume' to prevent cork spot-like physiological disorder (CSPD) in the skin, we optimized the fruit bagging treatment conditions using a light impermeable double-layered paper bag (2-layer bag), considering both prevention of CSPD and the red coloration of 'Kurenainoyume' skin and flesh. Bag-removal at 25, 35, and 45 days before harvest (DBH), resulted in good skin and flesh coloration without CSPD incidence. Moreover, there was no significant difference in fresh weight, soluble solid, or malic acid contents compared with the non-bagging control. Therefore, we recommend bag-removal from 25 to 45 DBH for 'Kurenainoyume' as a practical cultivation technique.

“…In recent decades, a wide range of technological advances have been developed in order to optimize the responsiveness of existing supply to the new characteristics of demand in the global fruit market. For example, advances in plant breeding technologies assisted by new biotechnological tools are enabling the development of new fruit varieties that allow cultivation in previously unsuitable areas, or that present new characteristics demanded by the consumer (Matsumoto et al. , 2016; Sabbadini et al.…”

PurposeThe purpose of this paper is to expand the understanding of the type of strategies that can be successful for firms located in the South to get integrated and compete in modern export fruit markets.Design/methodology/approachTo achieve the research purpose of the paper the authors carry out an in-depth case study. They analyze the export strategy of Patagonian Fruits Trade, an Argentinean leading exporter of apple, pear and kiwi.FindingsResults revealed that Patagonian Fruits Trade developed a strategy focused on supplying decommoditization to compete in modern fruit export markets. A key aspect of the firms' business model relies on its capability to meet the demand of high-income markets by providing conventional, organic and biodynamic club varieties. However, the sustainability of the strategy heavily relies on the firm's capability to fund club varieties' licenses and on the firm's ability to negotiate with clients and suppliers.Research limitations/implicationsAdopting a case study method limits the generalization of results. However, it provides new insights into the type of export strategies that can be successful in modern fruit markets as well as its main limitations.Originality/valueResults of the study, based on original empirical evidence, shed light on key factors for the integration of Southern fruit producers into modern fruit markets.
