Bolu steamed is one of the cakes that is enough to be contaminated by the community. The basic ingredient is wheat flour. Excessive use of wheat flour can interfere with the health of small bowel damage, so it is necessary to do substitution efforts with other flour such as cassava flour and green bean flour. Using cassava as the basic ingredient of steamed cakes is an alternative to adding nutrients. But the cassava is low in protein, so it is necessary to increase the source of proteins. Green beans have a fairly high protein content. Therefore, it is necessary to review the influence of the addition of green bean flour in steamed cakes made from cassava flour. The results showed the cassava flour affects the level of delight in the colour and flavor of the steamed bolu, while the addition of green bean flour is influential against the color, texture and flavor but does not affect the aroma of the steamed bolu. Based on proximate testing, moisture content of ash, protein levels, fat content and carbohydrate levels contained in the steamed Bolu does not exceed the standard based on the wet cake SNI, while the moisture content of the steamed Bolu exceeds the standards that can be influential On the shelf power of steamed cakes.

Efforts in developing food products continue to be carried out such as utilizing local commodities so that non-wheat flour processing can be used as a substitute for making food products in order to overcome dependence on wheat flour. One such effort is to make cookies from local ingredients, modified cassava flour known as MOCAF (Modified cassava flour).  This research was aimed to determine the effective mixture of Mocaf flour and ketapang seed on the characteristic of cookies based on nutritional value. The research design used a completely randomized design (CRD), with 5 treatments and 3 replications. This data was analyzed with ANOVA (analysis of variance) and if the data was significantly different analyzed continued with Duncan’s New Multiple Range Test (DNMRT) at the level 5%. The treatments used were A (100% Mocaf flour : 0% Ketapang seed), B (90% Mocaf flour : 10% Ketapang seed), C (80% Mocaf flour : 20% Ketapang seed), D (70% Mocaf flour : 30% Ketapang seed), E (60% Mocaf flour : 40% Ketapang seed). The results showed that the Mocaf flour and ketapang seed comparison significantly influenced the protein content, fat content, energy, texture, free fatty acid, and carbohydrate content, but not significantly affect moisture content and ash content.

Cassava (Manihotesculentacrantz) is not true cereals are largely grown all over the world. They are very important due to their excellent nutritional contents especially protein, crude fiber, and carbohydrates. Biscuits were prepared by mixing cassava and wheat flour. Six treatments were prepared by adding 10%, 20%, 30%, 40%, and 50% cassava flour with wheat flour (Sample B, C, D, E, and F respectively) along with controlled treatment of 100% wheat flour (A). The proximate composition of flours was analyzed and prepared biscuits were subjected to sensory evaluation and shelf-life estimation. The obtained data was analyzed statistically by Genstat Discovery Edition 3 (DE3), for Analysis of Variance (ANOVA) at a 5% level of significance. Statistical analysis showed that sensory parameters and overall acceptability of 80 parts wheat and 20 parts cassava flour incorporated biscuit was significantly superior to all biscuits formulations. The proximate results of the best product showed that moisture content, crude fat, crude protein, crude fiber, total ash content, and total carbohydrate were found 3.44±0.25%, 13.80±0.33%, 8.13±0.13%, 1.29±0.19%, 2.41±0.06%, and 70.99±0.50 (g/100g) respectively. The shelf life of the best product was estimated by analyzing acid value and moisture content of the product by using three different packaging materials biaxially polypropylene (BOPP), high-density polypropylene (HDPE), and polypropylene (PP) respectively. The shelf life of the best product (80-20) wheat and cassava flours was found to be satisfactory for 8 weeks. The projected shelf life was found high in polypropylene (PP) and high-density polypropylene (HDPE) for 13.5 and 17.81 weeks for acid value and moisture content respectively.

Sugar palm (Arenga pinnata) is a feather palm native to tropical Asia. In Vietnam, it is named Búng Báng or Đoác and grown only on the highlands in the central or northern part of Vietnam. It is utilized for many purposes, especially for Ta Vat wine production - a characteristic and unique product of Co Tu ethnic minority. However, because of the natural fermentation used in the production, the product quality is inconsistent. The purpose of this study was to examine a new procedure of using palm sap for making Ta Vat wine. Some characteristics of the sap, which was collected at Nam Giang district, Quang Nam province are determined, proving the potential of the sap for making wine product. The quality of sap changes quickly at room temperature. At low temperature (4 - 60C), the changes in sap quality are apparently slower. Examining some factors affecting its quality during the wine fermentation process, we determined the best parameters for the fermentation process as follows: inoculum size of 3% with cell density of about 1x108 cells/ml, the addition of the extract from the bark of Ceylon ironwood (Mesua ferrea L.) 4%. Keywords: Arenga pinnata, sap, Ceylon ironwood bark, Mesua ferrea L., wine fermentation.

The paper investigates technological parameters of the quality of low-alkaloid lupin of five cultivars selected and grown in the Republic of Belarus during the years from 2007 to 2017. Prospects for the use of the obtained seeds have been studied. This study reveals great influence of cultivar and climatic conditions during growth of lupin seeds on correlation of anatomic parts in seeds as well as on their physical properties. Cultivar of lupin seeds Jan is recommended for whole grain flour and graded flour production based on its anatomic composition, uniformity and physical properties. A comparative analysis of chemical composition, quality parameters and technological properties of lupin flour has been done. The chemical composition of lupin flour, of whole grain lupin flour, in particular, has been found to be relatively low in starch, high in protein, food fibers, minerals and organic acids. As a result, whole grain lupin flour has been proved to have higher food value when compared to traditional wheat flour. This paper demonstrates the difference between lupin flour characteristics and those of wheat flour in terms of color, acidity, enzymatic activity and adsorbing properties. This study reveals the possibility of use of lupin flour in bakery products by substituting traditional types of flour with lupin flour at 10-30% levels, as well as by replacing egg products with lupin flour at 25-50% levels. The work highlights the use of lupin flour at the stages of dough kneading, dough preparation, foam and emulsion production mainly by using rapid dough making methods.Practical applicationsRecommendations have been made on the usage of lupin flour in the technological process of bakery products manufacturing, macaroni and flour confectionery products production.

Total mercury, monomethylmercury (CH3Hg), and dimethylmercury ((CH3)2Hg) in edible muscle were examined in 229 samples, representing seven freshwater and eight saltwater fish species and several species of marine invertebrates using ultraclean techniques. Total mercury was determined by hot HNO3/H2SO4/BrClldigestion, SnCl2 reduction, purging onto gold, and analysis by cold vapor atomic fluorescence spectrometry (CVAFS). Methylmercury was determined by KOH/methanol digestion using aqueous phase ethylation, cryogenic gas chromatography, and CVAFS detection. Total mercury and CH3Hg concentrations varied from 0.011 to 2.78 μg∙g−1 (wet weight basis, as Hg) for all samples, while no sample contained detectable (CH3)2Hg (<0.001 μg∙g−1 as Hg). The observed proportion of total mercury (as CH3Hg) ranged from 69 to 132%, with a relative standard deviation for quintuplicate analysis of about 10%; nearly all of this variability can be explained by the analytical variability of total mercury and CH3Hg. Poorly homogenized samples showed greater variability, primarily because total mercury and CH3Hg were measured on separate aliquots, which vary in mercury concentration, not speciation. I conclude that for all species studied, virtually ail (>95%) of the mercury present is as CH3Hg and that past reports of substantially lower CH3Hg fractions may have been biased by analytical and homogeneity variability.

The sedimentation behavior of aqueous solutions of digitonin and of cattle rhodopsin in digitonin has been examined in the ultracentrifuge. In confirmation of earlier work, digitonin was found to sediment as a micelle (D-1) with an s20 of about 6.35 Svedberg units, and containing at least 60 molecules. The rhodopsin solutions sediment as a stoichiometric complex of rhodopsin with digitonin (RD-1) with an s20 of about 9.77 Svedberg units. The s20 of the RD-1 micelle is constant between pH 6.3 and 9.6, and in the presence of excess digitonin. RD-1 travels as a single boundary also in the electrophoresis apparatus at pH 8.5, and on filter paper at pH 8.0. The molecular weight of the RD-1 micelle lies between 260,000 and 290,000. Of this, only about 40,000 gm. are due to rhodopsin; the rest is digitonin (180 to 200 moles). Comparison of the relative concentrations of RD-1 and retinene in solutions of rhodopsin-digitonin shows that RD-1 contains only one retinene equivalent. It can therefore contain only one molecule of rhodopsin with a molecular weight of about 40,000. Cattle rhodopsin therefore contains only one chromophore consisting of a single molecule of retinene. It is likely that frog rhodopsin has a similar molecular weight and also contains only one chromophore per molecule. The molar extinction coefficient of rhodopsin is therefore identical with the extinction coefficient per mole of retinene (40,600 cm.2 per mole) and the E(1 per cent, 1 cm., 500 mµ) has a value of about 10. Rhodopsin constitutes about 14 per cent of the dry weight, and 3.7 per cent of the wet weight of cattle outer limbs. This corresponds to about 4.2 x 106 molecules of rhodopsin per outer limb. The rhodopsin content of frog outer limbs is considerably higher: about 35 per cent of the dry weight, and 10 per cent of the wet weight, corresponding to about 2.1 x 109 molecules per outer limb. Thus the frog outer limb contains about five hundred times as much rhodopsin as the cattle outer limb. But the relative volumes of these structures are such that the ratio of concentrations is only about 2.5 to 1 on a weight basis. Rhodopsin accounts for at least one-fifth of the total protein of the cattle outer limb; for the frog, this value must be higher. The extinction (K500) along its axis is about 0.037 cm.2 for the cattle outer limb, and about 0.50 cm.2 for the frog outer limb.
