- Abstract
The use of different foods, herbs, and spices to treat or prevent disease has been recorded for thousands of years. Egyptian papyrus, hieroglyphics and ancient texts from the Middle East have described the cultivation and preparations of herbs and botanicals to “cure the sick.” There are even older records from China and India. Some ancient scripts describe the use of medicinal plants which have never been seen within European cultures. Indeed, all ancient civilizations have pictorial records of different foods, herbs, and spices being used for medical purposes. However, there are fundamental questions and issues pertaining to the scientific evidence for the use of these agents or their extracts in modern medicine. These issues are explored in Ancient and Traditional Foods, Plants, Herbs and Spices used in the Middle East.Features· Describes uses and applications of plant-based materials from different countries of the Middle East. · Each chapter has unique cross references to foods, herbs, spices and botanicals· Bridges molecular biology, physiology and medical sciences· Coverage includes herbal medicines, supplements, lifestyle patterns, nutrition, and plant-based diets · Each chapter describes usage and applications of traditional foods and botanicals; historical background; toxicity; cautionary notes; and summary pointsThere have been considerable advances in scientific techniques over the last few decades. These have been used to examine the composition and applications of traditional cures. Modern science has also seen the investigation of herbs, spices and botanicals beyond their traditional usage. Written by international experts, this is an essential read for food researchers, food scientists, and nutritionists, researchers and health professionals with an interest in the potential therapeutic value of Middle Eastern food components. The book will also be of relevance to physicians and pharmacologists.

- Abstract
Phytochemicals are plant derived chemicals which may bestow health benefits when consumed, whether medicinally or as part of a balanced diet. Given that plant foods are a major component of most diets worldwide, it is unsurprising that these foods represent the greatest source of phytochemicals for most people. Yet it is only relatively recently that due recognition has been given to the importance of phytochemicals in maintaining our health. New evidence for the role of specific plant food phytochemicals in protecting against the onset of diseases such as cancers and heart disease is continually being put forward. The increasing awareness of consumers of the link between diet and health has exponentially increased the number of scientific studies into the biological effects of these substances. The Handbook of Plant Food Phytochemicals provides a comprehensive overview of the occurrence, significance and factors effecting phytochemicals in plant foods. A key of objective of the book is to critically evaluate these aspects. Evaluation of the evidence for and against the quantifiable health benefits being imparted as expressed in terms of the reduction in the risk of disease conferred through the consumption of foods that are rich in phytochemicals. With world-leading editors and contributors, the Handbook of Plant Food Phytochemicals is an invaluable, cutting-edge resource for food scientists, nutritionists and plant biochemists. It covers the processing techniques aimed at the production of phytochemical-rich foods which can have a role in disease-prevention, making it ideal for both the food industry and those who are researching the health benefits of particular foods. Lecturers and advanced students will find it a helpful and readable guide to a constantly expanding subject area.

2006 metais Lietuvos sodininkystės ir daržininkystės instituto bandymų laukuose tirta azoto normų įtaka pipirmėčių (Mentha piperita L.) žalios masės derliui ir kokybei. Visos tyrimams naudotos pipirmėtės: varietetas iš Lietuvos, varietetas iš Lenkijos ir ‘Krasnodarskaja’ veislė, papildomai patręštos azoto trąšomis, derėjo gausiau. Tyrimais nustatyta, kad didžiausias žalios masės derliaus priedas gautas, tręšiant pipirmėtes didžiausia azoto norma N120 per 3 kartus (N60+30+30). Pipirmėčių žalios masės derlius taip pat priklauso nuo jų genetinių savybių. Gausiausiai derėjo pipirmėtės iš Lenkijos, mažiausiai derlingas buvo varietetas iš Lietuvos, o ‘Krasnodarskaja’ veislė – vidutiniškai derlinga. Cheminių analizių duomenimis, papildomas tręšimas azotu iš esmės didina nitratų kiekį pipirmėčių žalioje masėje, tačiau nekeičia kitų biocheminių rodiklių: bendrojo cukraus, tirpių sausųjų medžiagų, askorbo rūgšties, karotinoidų bei eterinių aliejų kiekio. The influence of nitrogen rates on peppermint (Mentha piperita L.) fresh weight yield and quality was investigated in the experimental fields of the Lithuanian Institute of Horticulture in 2006. All the peppermints (Lithuanian variety, Polish variety and variety ‘Krasnodarskaja’) used in the investigations, additionally fertilized with nitrogen fertilizers yielded more abundantly. Investigations showed that the biggest increase of fresh weight was obtained when peppermints were fertilized with the biggest nitrogen rate N120 for three times (N60 + 30 + 30). Peppermint fresh weight yield also depends on their genetic properties. Polish peppermint yielded most abundantly, Lithuanian variety was the least productive, and variety ‘Krasnodarskaja’ – averagely productive. According to the data of chemical analysis, additional fertilization with nitrogen significantly increases the amount of nitrates in peppermint fresh weight, but doesn’t change other biochemical parameters – the amount of total sugar, dry soluble solids, ascorbic acid, carotenoids and essential oil.

2006–2007 m. Lietuvos žemės ūkio universitete tirta skirtingai laikytų ‘Swojecki’ veislės topinambų gumbų kokybė. Gumbai buvo laikomi maišuose, smėlyje ir durpėse keturis mėnesius esant 2°C oro temperatūrai ir 95 proc. santykinei drėgmei. Gumbuose standartiniais metodais nustatyta: sausųjų medžiagų, tirpių sausųjų medžiagų kiekiai bei bendrojo, invertuoto cukrų ir sacharozės kiekiai. Didžiausias sausųjų medžiagų kiekis bei jo padidėjimas laikant nustatytas maišuose laikytuose gumbuose. Po keturių laikymo mėnesių mažiausiai tirpių sausųjų medžiagų (12,49 proc.) buvo taip pat maišuose laikytuose gumbuose. Po dviejų mėnesių visuose topinambų gumbuose, nesvarbu, kur jie buvo laikyti, aptikta mažiausiai bendrojo cukraus ir sacharozės. Didžiausi esminiai invertuoto cukraus kiekiai rasti maišuose laikytuose topinambų gumbuose viso tyrimo metu. The quality of Helianthus tuberosus L. tubers during storage was evaluated in LUA in 2006–2007. The tubers were stored in bags, sand and peat in refrigerator KX–Ž where temperature was 2°C and RH 95%. The index of chemical composition in tubers was identified by standard methods: the quantity of dry matter, dry soluble solids, total, reducing sugar and sucrose. It was determined that after four storage months, when tubers were kept in bags, the amount of dry matter was 2.2 times bigger comparing with tubers, which were kept in sand and peat. According to our results, the biggest loss of dry soluble solids was established after four storage months (4.01%), when tubers were kept in bags. Irrespective of storage conditions, the lowest amounts of total sugar and sucrose were determined after two storage months. Essential biggest amounts of reducing sugars were established when tubers where kept in bags.
