“…The basic principles of biocrystallization are described in (Busscher et al 2010a, the application for carrots is described in (Busscher et al 2010b). The biocrystallization can be applied on many different food samples, from which a watery extract or juice can be made such as milk and milk products (Kahl et al 2009), carrots (Busscher et al 2010a, b) or wheat (Szulc et al 2010).…”

The market for processed food is rapidly growing. The industry needs methods for "processing with care" leading to high quality products in order to meet consumers' expectations. Processing influences the quality of the finished product through various factors. In carrot baby food, these are the raw material, the pre-processing and storage treatments as well as the processing conditions. In this study, a quality assessment was performed on baby food made from different pre-processed raw materials. The experiments were carried out under industrial conditions using fresh, frozen and stored organic carrots as raw material. Statistically significant differences were found for sensory attributes among the three autoclaved puree samples (e.g. overall odour F=90.72, p<0.001). Samples processed from frozen carrots show increased moisture content and decrease of several chemical constituents. Biocrystallization identified changes between replications of the cooking. Pre-treatment of raw material has a significant influence on the final quality of the baby food.

“…It can be caused both by insufficient accuracy of the control of experimental conditions (the degree of purity of the cuvettes, the homogeneity of the solution, the inclination of the cuvette during drying), and by the chaotic character of the process of texture formation. The authors of [14,15] consider the latter to be the case, as they also report low reproducibility and high variability of the results of the method of biocrystallization. According to their analysis, the crystallization stage is the primary source of the variability of results.…”

“…Depending on the type of pattern or texture, various authors offered such evaluation criteria as: the number of optical density fluctuations [9] or the brightness distribution of the digital image [11] in circular sections of different diameters; the fractal dimension of Minkowski [5] and the local connected fractal dimension of the image [12]; parameters of gray-scale histograms at several scales [13][14][15]; the structural and spectral characteristics of an image region as a function of time [10].…”

Analysis of the patterns formed during the drying of biological fluids is employed for research and diagnosis in medicine and agriculture. Saline solutions of native proteins and DNA are characterized by zigzag patterns, which could be quantitatively described using the specific length of zigzags L specific . The aim of this study was to analyze a wide number of characteristics in order to identify those most sensitive to the effects of various physical and chemical factors on the protein structure. We examined the films prepared from salt solutions of bovine serum albumin (BSA) under varying conditions, viz.: a proportional change in the concentration of the components, substitution of NaCl with NaF and NaBr, temperature treatment, gamma irradiation, and addition of trivalent iron and biologically active flavin mononucleotide. The results revealed that the distribution of zigzag segment lengths was approximately lognormal, and the distribution of angles between the segments was approximately logistic. Two parameters appeared to be the most informative, viz. the average length of the segments, mainly depending on Cl -concentration, and the number of segments, depending on: Cl -concentration, concentration of the non-aggregated (but not necessarily unfragmented) protein, and the excess concentration of ions and low molecular weight compounds. KEY WORDS: BSA, film, zigzag patterns, texture, statistical distribution. Аналіз патернів, що формуються при висиханні біологічних рідин, використовується для досліджень і діагностики в медицині і сільському господарстві. Для сольових розчинів нативних білків і ДНК характерні зигзагоподібні патерни, які можна кількісно описати за допомогою питомої довжини зигзагів L specific . У даній роботі ми аналізуємо розширений ряд характеристик цих патернів з метою виявити найбільш чутливі до дії різних фізичних і хімічних факторів на структуру білка. Були розглянуті плівки, отримані з сольових розчинів бичачого сироваткого альбуміну (БСА) при пропорційній зміні концентрації компонентів, заміні NaCl на NaF і NaBr, температурній обробці, гамма-опроміненні, а також додаванні тривалентного заліза і біологічно активної речовини -флавінмононуклеотида. Було визначено, що розподіл довжин сегментів зигзагів має близький до логнормального характер, а розподіл кутів між сегментами -близький до логістичного. Дані показали, що найбільш інформативними є два параметри: середня довжина сегментів, яка переважно залежить від концентрації Cl -, і кількість сегментів, яка залежить від концентрації Cl -, концентрації неагрегованого білка (але не обов'язково нефрагментованого), а також від надлишкової концентрації іонів і низькомолекулярних сполук.

“…The computational image analysis procedure for the evaluation of biocrystallogram images should reflect all of the characteristics of a biocrystallogram as a three dimensional, colored crystal structure, coordinated with zones relative to a center (Meelursarn, 2007;Andersen et al, 1999). In contrast, previous studies have used a texture analysis that applied 32 grey levels and a single type of circular region-of-interest (ROI) approach (Meelursarn, 2007;Busscher et al, 2010). In a study using a different approach, a feed-forward neural network was applied to biocrystallization in conjunction with computer vision techniques to discriminate sweet red pepper products that were prepared by different methods, such as freezing and pureeing.…”
