Carbohydrates are the main source which required to maintain energy equilibrium and normal life activities. In acorn kernel, soluble polysaccharides and starch are the main carbohydrate. In order to accurately measure the carbohydrate content of the acorn kernel in Nanjing Area. Dual-wavelength spectrophotometry and anthrone-sulfuric methods were applied to measure the content of amylose, amylopeetin and soluble polysaccharides,respectively.The other two samples were simultaneously measured for comparative analysis.Testing results show that acorn kernel contain about 79.40% of starch, amylopectin content was up to 59.01%, polysaccharide content is 6.53%.The results indicate that acorn kernel was an important raw material for preparing food, feed and starch-based composites.

This study aimed to determine the best of protein concentrate fortification of nile tilapia (Oreochromis niloticus) on sweet bread. The treatment given consists of K0 (without fortification of fish protein concentrate), K1 (5% of fish protein concentrate fortification), K2 (10% of fish protein concentrate fortification), K3 (15% of fish protein concentrate fortification). The parameters analyzed in this study were sensory, physical and chemical analysis. The results showed that tilapia protein concentrate fortification had a significant effect on the sensory (organoleptic) value, physical analysis (volume development test) and chemical analysis (moisture, protein, fat, and carbohydrate content), but did not significantly affect on ash content. The best treatment was K1 (5% of fish protein concentrate fortification) with an average number of panelists who liked 77 people (96.25%), with the characteristics of bread which included appearance (brownish yellow and there were a few brown spots), aroma (typical of bread), texture (soft, elastis and good), taste (sweet) with development volume, moisture, ash, protein, fat, and carbohydrate content was  81.55%, 28.71%, 1.21%, 14.93%, 9.35%, and 45.80%, respectively.

Important Symptom

The content and structure of mental representation of economic crises were studied and the flexibility of the structure in different social contexts was tested. Italian and Swiss samples (Total N = 98) were compared with respect to their judgments as to how a series of concrete examples of events representing abstract indicators were relevant symptoms of economic crisis. Mental representations were derived using a cluster procedure. Results showed that the relevance of the indicators varied as a function of national context. The growth of unemployment was judged to be by far the most important symptom of an economic crisis but the Swiss sample judged bankruptcies as more symptomatic than Italians who considered inflation, raw material prices and external accounts to be more relevant. A different clustering structure was found for the two samples: the locations of unemployment and gross domestic production indicators were the main differences in representations.

The physical and chemical characteristics of the fruit have immense significance as they ultimately affect the quality of processed productsprepared from them. Over ripening of Sapota (Manilkara zapota) fruits at the post-harvest stage usually results in dramatic decline in quality.In the present study, physico chemical analysis (which includes Weight loss, Colour, Texture, TSS, pH, TA and Ascorbic acid content) ofedible Aloe vera gel coated Sapota fruits packed in LDPE and stored at 15 ± 2? were studied at regular intervals of 5 days i.e., 0th,5th, 10th,15thand 20th days. The dip treatment of Aloe vera gel coating 1:2, 7 minutes had best retained the physico chemical characteristics than the othertreatments performed and was found to be the most effective treatment in maintaining the fruit quality attributes along with the shelf lifeextension of about 20 days.DOI: http://dx.doi.org/10.3126/ijasbt.v3i1.11703 Int J Appl Sci Biotechnol, Vol. 3(1): 20-25

Lignin has great potential for utilization as a green raw material or as an additive in various industrial applications, such as energy, valuable chemicals, or cost-effective materials. In this study, we assessed a commercial form of lignin isolated using LignoBoost technology (LB lignin) as well as three other types of lignin (two samples of non-wood lignins and one hardwood kraft lignin) isolated from the waste liquors produced during the pulping process. Measurements were taken for elemental analysis, methoxyl and ash content, higher heating values, thermogravimetric analysis, and molecular weight determination. We found that the elemental composition of the isolated lignins affected their thermal stability, activation energies, and higher heating values. The lignin samples examined showed varying amounts of functional groups, inorganic component compositions, and molecular weight distributions. Mean activation energies ranged from 93 to 281 kJ/mol. Lignins with bimodal molecular weight distribution were thermally decomposed in two stages, whereas the LB lignin showing a unimodal molecular weight distribution was decomposed in a single thermal stage. Based on its thermal properties, the LB lignin may find direct applications in biocomposites where a higher thermal resistance is required.

Until now the raw material of wood especially Gelam (Melaleuca cajuputi) for supporting the construction of housing and other infrastructures is increasingly demand in Indonesia. On the Island of Borneo that partly consists of peat swamps needs Gelam very large and continuous, particularly for residential development. Ecological aspects are very important for supporting the silvicultural strategies. The aim of this study is to analyze ecological aspects which are very influence especially physical and chemical soil properties and microclimate as well. The utilization of study is to determine the silvicultural strategies for continuing production and conservation of Gelam in the future. The method was used a field survey around Gelam forest and did collecting samples and measuring there. The results showed in South Borneo the potency of Gelam is only 2,9-7,1 m3/ha and decreasing yearly. Normally Gelam with a diameter <4 cm have been cut down, as well as > 30 cm. Gelam can grow on the peat swamp forest where the soil was low pH 3.5-3.9. Most of pH of soil in these areas was influenced by phyrite (FeS2 of 0.4-2.2% and highest of Fe 90-302 ppm. C organic in the soil was included low-moderate 5.5-10.0%. Result of soil physic analysis showed composition of sand, dust, and clay of 9 : 54 : 57 % respectively. Temperature and humidity around peat swamp forest areas where was found Gelam were 31-33oC and 63-73% respectively. Most of areas around Gelam were grown Gelam Tikus (Syzygium inophylla) and some kind of shrubs.Key words: Gelam, potency, ecological aspects, silviculture

Abstract With the upcoming medical Cannabis regulation, quality control methods on raw material will be required. Besides testing for contaminants and potency, there are also pharmaceutical and forensic interests in the determination of the terpene profile in different strains of Cannabis as complementary identification methods. A simple non-destructive HS-SPME GC-MS method was used to identify the terpene content in twelve Cannabis samples, four of them were of the hemp type (Harle-tsu), seven from various marihuana types and one of the intermediate type. They all were previously analyzed by HPLC to determine the potency (THC and CBD content). Spectral library matching was used to identify the terpenes compounds. Thirty terpenes compounds were detected, nine of them were present in all Cannabis samples and used to find their terpene profile: α-pinene, β-pinene, β-myrcene, D-limonene, terpinolene, linalool, caryophyllene, α-bergamotene and humulene. Three of them, caryophyllene, α-pinene and β-myrcene were found as larger components in most of samples. A principal components analyses (PCA) was performed. The four hemp type samples showed two different profiles, two samples showed caryophyllene as main component and the others two with β-myrcene as such. The marihuana type samples showed wider profiles with no clear patterns at all, which is not surprising because of the low number of samples. The simple methodology shows viable to set the terpenes profile for analyses of raw Cannabis material. Suitability for differentiation between different sorts of types needs more studies, with increasing numbers of samples.
