Yenilebilir kaplama İle kaplanan Ayı Üzümü (Vaccinium Arctostaphylos L.) meyvesinin bazı kalite özelliklerinin belirlenmesi

In this study, blueberry fruit, which is consumed joyfully, was coated with edible coating material ( SemperfreshTM) and stored for 15 days at 4 °C. Antioxidant properties and some physical properties were determined after harvest 5 with days intervals (0, 5th, 10th, 15th days). In uncoated fresh fruits, the amount of dry matter soluble in water was determined as 13.22%, pH 3.41, titratable acidity 1.01%, reducing sugar 8.54g/100g, saccharose 0.17g/100g, total sugar 8.72g /100g, vitamin C 20.37mg/100g, L value 27.09, vitamin A value 0.18, vitamin B value 0.60, total phenolic content 2398.65 mg gallic acid/100g dry weight, DPHH radical scavenging activity (IC50 value) 0.24 and, ABTS radical scavenging activity (IC50 value) 7.61.Coating with SemperfreshTM was statistically significantly effective over the identified parameters in blueberry fruit (P< 0.01). When all parameters were examined in the study, it was seen that blueberry fruit lost less weight as a result of 15-day storage at 4°C when coated with SemperfreshTM. The amount of ascorbic acid could be determined up until the 10th day.Bu çalışmada sevilerek tüketilen ayı üzümü meyvesi, yenilebilir kaplama malzemesi ile (SemperfreshTM) kaplanarak 4 °C’ de 15 gün depolanmıştır. Hasattan sonra 5 gün aralıklarla (0., 5., 10., 15. gün) antioksidan özellikleri ve bazı fiziksel özellikleri belirlenmiştir. Kaplanmamış taze meyvelerde suda çözünür kuru madde miktarı % 13,22, pH 3.41, titrasyon asitliği %1.01, indirgen şeker 8.54g/100g, sakaroz 0.17 g/100g, toplam şeker 8.72 g/100g, C vitamini 20.37 mg/100g, L değeri 27.09, a değeri 0.18, b değeri 0.60, toplam fenolik madde 2398.65 mg gallik asit/100g kuru ağırlık, DPHH radikal giderme aktivitesi (IC50 değeri) 0.24, ABTS radikal giderme aktivitesi (IC50 değeri) 7.61 olarak belirlenmiştir. SemperfreshTM’le kaplama ayı üzümü meyvesinde belirlenen parametreler üzerine istatistiki olarak önemli derecede etkili olmuştur (P< 0.01). Araştırmada bütün parametreler incelendiğinde ayı üzümü meyvesinin 4°C’de 15 günlük depolama sonucunda SemperfreshTM’le kaplandığında ağırlık kaybının daha az olduğu görülmüştür. Askorbik asit miktarı ise 10. güne kadar belirlenebilmiştir

Biochemical content of cherry laurel (Prunus laurocerasus L.) fruits with edible coatings based on caseinat, Semperfresh and lecithin

: Cherry laurel is one of the most important cherry species and naturally grown in Black sea region in Turkey. Its fruits are sold at high price in local markets in northern parts of Turkey. Cherry laurel fruits are very perishable with a limited shelf life due to a high metabolic activity and susceptibility to mechanical damage and microbial attack. The effect of edible coatings (EC) based on caseinat, Semperfresh and lecithin on the fruit quality, bioactive content and antioxidant activity of cherry laurel fruits stored at 4 ± 1 °C for 15 days was evaluated. The EC fruits compared with uncoated fruits in terms of weight loss, brix, color, pH, titratable acidity, reducing sugar, total sugar, sucrose, total phenolic content, DPPH-IC50, ABTS-IC50, total yeast-mold count, number of total mesophilic aerobic bacteria and ascorbic acid (Vitamin C). Results showed that Semperfresh coating was more promising on titratable acidity (0.26%), pH (4.63), invert sugar (11.77 g/100 g), total sugar (11.96 g/100 g) and sucrose (0.13 g/100 g), caseinat coating was found more promising for count of total yeast-mold count (2.93 log kob/g) and total mesophilic aerobic bacteria (3.44 log kob/g) and lecithin coating was more promising in terms of weight loss (6.77%). For radical scavenging activity and total phenolic content, Semperfresh was found more useful. Thus, caseinat, Semperfresh and lecithin showed to be a promising alternative in prolonging shelf life and preserving the quality of cherry laurel

Using of Weeds as Food in Eastern Anatolia Region

Several herb can grow naturally thanks to climate and geographical features of Turkey. Although there are approximately one million weed in the world, there are still many unidentified weeds. While more than ten thousand weeds are used as a food, only 3000 weeds species are cultivated in Turkey. Eastern Anatolia region is one of the most important regions of Turkey in terms of consuming weeds. The rate of endemic plants is higher in this region, most of them are important economically, because they can be used as a medicinal plants, spices, ornaments, dyes or food. Not only these are utilized as raw or cooked food but also flavorant
