Multifloral Honey

Bee products, such as honey, pollen, and bee bread, are an excellent source of bioactive ingredients, including minerals, having a health-supporting effect. However, due to the specific sensory properties of bee pollen and bee bread, the best way to include them in a diet is to add them to honey. Therefore, the aim of this paper was to evaluate the influence of the added bee pollen or bee bread on selected minerals content in multifloral honey. The mineral content was analyzed using absorption atomic spectrometry (FAAS) with prior dry mineralization. On the basis of obtained results, it was found that the addition of bee pollen or bee bread to honey significantly influences the content of selected macro- and microelements, excluding sodium. The greatest increase in mineral content was observed for magnesium, iron, and zinc. Enrichment of honey with the highest dose of bee pollen or bee bread resulted in an over 20-fold increase in the Mg and Fe content, and an over 14-fold increase in the Zn content. Honey enriched with the maximum addition of bee pollen was characterized by a higher content of K, Ca, Mg, Fe, and Cu compared to honey with bee bread. Due to a fact that both bee pollen and bee bread are good sources of minerals, their addition to honey significantly increases its ability to cover daily demand for macro- and microelements.

Abstract. Pratama SN, Sudarsono, Ardie W, Khumaida N, Sukma D. 2021. Development of phenotypic markers and contrast genotype candidates of target minerals related to cassava. Biodiversitas 22: 3049- 3056. Cassava leaves have various macro and micro-nutrients with varying levels, such as magnesium, iron, and zinc. The differences in genotypes of cassava may result in different mineral content in cassava leaves. This study aims to determine the estimator phenotypic markers and contrast genotype candidate selection related to target minerals. This study used a one-factor treatment composed of 12 cassava genotypes and arranged in a randomized block design (RBD) which each treatment was repeated 3 times. The observation was conducted on the leaves' qualitative and quantitative characters such as plant growth, leaf morphology, and leaf mineral content characters. The observation was performed at 3 and 6 months after planting. The results showed that the quantitative and qualitative characters that could be used as estimator for mineral content in cassava leaves are the Soil Plant Analysis Development (SPAD)- Chlorophyll value and leaf color. Genotypes G6-1-15-4-3, G6-2-15-1-1, G6-2-15-3-3 (lowest) and Malang (G4D0), G4D1-222, G3D2-413 (highest) could be categorized as contrast genotypes based on SPAD-value and mineral content. The strong positive correlation between Mg and Fe content with SPAD suggested that SPAD is a possible marker for high Mg and Fe content in leaves. Adversely, a weak relationship between SPAD and Zn content in leaves showed that SPAD is a weak marker for Zn content in leaves. Further research related to molecular markers development can be carried out based on these results.

Melissopalynological Analysis

The goal of the study was to evaluate the pollen spectrum, antioxidant capacity and mineral content of four Hungarian honey types, using multivariate statistical analysis. The light colored honeys were represented by milkweed honey and a multifloral (MF) honey with dominant pollen frequency of linden (MF-Tilia); the darker ones were goldenrod honey and a multifloral honey with Lamiaceae pollen majority (MF-Lamiaceae). The pollen spectrum of the samples was established with melissopalynological analysis. The absorbance of the honeys positively correlated with the antioxidant capacity determined with three of the used methods (TRC, TEAC, DPPH), but not with ORAC. The latter method correlated negatively also with other antioxidant methods and with most of the mineral values. MF-Tilia had high ORAC value, K and Na content. The MF-Lamiaceae had the highest K, Mg, P, S, Cu and Zn content, the last five elements showing strict correlation with the TRC method. The darker goldenrod honey had higher SET values and total mineral content, than the milkweed honey. The above character-sets facilitate identification of each honey type and serve as indicators of variety. The antioxidant levels and mineral content of honeys allowed their clear separation by principal component analysis (PCA).

Iron And Zinc

Bananas and plantains (Musa sp.) are major staple foods in many developing countries of the world. Although bananas are rich in carbohydrate, fiber, protein, fat, and vitamins A, C, and B6 they are largely deficient of iron (Fe), iodine, and zinc (Zn). A small increase in the micronutrient content of bananas could play a major role in combating disorders that are due to deficiency of mineral micronutrients such as Fe and Zn. The objective of this study was to determine the Fe and Zn content of 47 banana genotypes from a germplasm collection in Uganda using atomic absorption spectrophotometry. The Fe and Zn content showed wide variability and highly significant differences (P < 0.001) within and among the different banana categories selected for this study. The highest average Fe content (1.42 mg/100 g) was found in ‘Saba’ (ABB) while the least Fe content (0.06 mg/100 g) was found in ‘Kikundi’ (AAA). The highest average Zn content (1.21 mg/100 g) among the analyzed accessions was found in ‘Kivuvu’ (ABB) while Zn was not detectable in both ‘Kabucuragye’ (AAA) and ‘Grand Naine’ (AAA). Considering these figures, there is a greater than 20-fold variation in the Fe and Zn levels of the banana genotypes used this study suggesting that genetic improvement of genotypes for enhanced micronutrient levels may be achieved by breeding.

Advanced wheat genotypes were tested for agronomic as well as grain iron and zinc content traits. The analysis of variance indicated variation for all traits except iron (Fe) and zinc (Zn). The grain Fe content ranged from 39-58 mg/kg whereas grain Zn ranged from 32-47 mg/kg among the tested lines. A significant positive correlation (0.45) was observed between grain Fe and Zn content. There was no association between yield and grain Fe and Zn content indicating that improvement in these micronutrients will not have any undesirable affect on yield. The data was further analysed for principal component analysis and genotype by trait association. The first five principal components viz., PC1 (0.3149), PC2 (0.2198), PC3 (0.1461), PC4 (0.10) and PC5 (0.0923) accounted for 0.87 of the total variation. The major traits contributing to the PC1 are days to heading, days to maturity, grain iron content and yield. The cluster analysis revealed significant variation among the tested germplasm thus providing opportunities for increasing the micronutrient content along with yield through hybridization with high micronutrient content lines.

Complementary feeding is a transition of the baby's intake over 6 months to meet the nutritional needs in addition to breast milk. Complementary feeding should contain complete nutritional components especially in minerals. Minerals are elements needed by the body for the overall body function. Children require calcium (Ca), iron (Fe), and zinc (Zn) for their body growth to prevent stunting. This study was aimed to analyse Ca, Fe and Zn content in the formulated fish protein hydrolysate (FPH) complementary feeding porridge. A total of three formulations were produced namely F1, F2 and F3 and analysed for mineral content following AOAC method 999.11. From the analysis, F3 had the highest Fe content (38.547 mg/100 g) and Zn content (5.751 mg/100 g) while F1 had the highest Ca content (65.152 mg/100 g). Overall, F3 had the best mineral content to be formulated as a suitable FPH complementary feeding instant powder.

The Relationship

Artemisia species and radish demonstrate intensive allelopathic properties and high ability to hyperaccumulate heavy metals, but their interaction has not been studied up to date. In a pot experiment, the relationship between wormwood (A. scoparia L.) and radish grown individually or intercropped, without and with Pb(NO3)2 supply, was investigated. The intercropping had significant effects in both species, as a consequence of metal allelopathy. Radish showed decrease of root biomass (1.75- fold), Fe, Mn and Zn content (2-fold), Cu level (5.4-fold), and a 1.59-fold Pb increase in the leaves. In wormwood, a 1.75-fold increase of root biomass, as well as a 7.2- and 2.8-fold increase of root and leaf Fe content, respectively, were recorded. A. scoparia, the most Pb tolerant out of the 11 Artemisia species investigated, accumulated 6.6 and 9.9 times more Pb in leaves and roots respectively, compared to radish, under Pb supply which encouraged the growth of both plants. The intercropping under Pb supply induced a three-fold decrease of radish root biomass and 7.8-fold decrease of Pb content. Changes in plant antioxidant activity were recorded only under Pb supply and were not related to radish-wormwood interaction: the leaf phenolics content and antioxidant activity displayed 1.4- and 2- fold increases, respectively, in radish, and 1.4- and 1.6-fold decreases in wormwood. Synchronous changes in elemental composition of wormwood and radish in intercropping conditions, without or under Pb supply, suggest the significance of this phenomenon in plants interaction and arise high prospects of A. scoparia utilization to tackle weeds and soil Pb pollution

Percent Absorption

The Thriposha programme is a community-level nutrition intervention in Sri Lanka that provides a combination of energy, protein and micronutrients as a ‘ready-to-eat’ cereal-based food. We measured the bioavailability of Fe and Zn from Thriposha formula at two different molar ratios of Zn:Fe in order to determine the effect on Fe and Zn absorption. Children 4–7 years (n 53) were given a meal prepared with 50 g Thriposha containing 1·5 mg Zn as zinc sulphate and either 9 mg (high Fe concentration (HiFe)) or 4·5 mg (low Fe concentration (LoFe)) Fe as ferrous fumarate. Zn and Fe percent absorption were measured using stable isotopes by tracer:tracee ratio and by incorporation of erythrocytes, respectively. Percent Fe absorption from the two meals was similar (6·6 % (4·8) v. 4·8 % (2·6); P = 0·15), but total Fe absorption was significantly higher from the HiFe meal (0·59 (0·43) mg) than the LoFe meal (0·20 (0·12) mg; P = 0·01). There was no significant difference between the two groups in Zn absorption (10·7 % (0·9) v. 8·8 % (1·4), P = 0·13, respectively). Decreasing the amount of Fe in Thriposha did not cause a significant change in the percent absorption of Fe and Zn, but significantly lowered the total amount of absorbed Fe. These results demonstrate the utility of maintaining a higher Fe content in this supplement. Further studies to increase Zn content are warranted while maintaining a HiFe.

In this study we analysed mineral composition of bee pollen of different plant origin collected across Serbia using inductively coupled plasma - optical emission spectrometry. The most abundant elements were potassium, calcium, and magnesium. The samples were also exceptionally rich in iron and zinc, which are very important as nutrients. Judging by our findings, mineral composition of bee pollen much more depends on the type of pollen-producing plant than on its geographical origin.

The aim of the study was to determine the basic chemical composition and mineral content in the sirloin and offal of fattener pigs, taking their sex into consideration. In addition, comparative analysis of the content of chemical and mineral components in the sirloin and offal was performed. The experimental material included 24 crossbred (Polish Landrace × Polish Large White) fatteners, from which samples of sirloin (musculus longissimus lumborum), liver, heart, and kidneys were collected for the analysis. A significant effect of the sex on the fat content in the sirloin and liver and on the level of magnesium (Mg), zinc, and iron (Fe) in the sirloin was demonstrated. Significant differences were found in the basic chemical composition and mineral content between the sirloin and the offal. In comparison with the liver, the sirloin contained lower amounts of protein and fat and higher potassium and Mg contents. In turn, the offal was shown to be a rich source of sodium, calcium, and trace elements (Fe, manganese, and copper). The mean cadmium concentration in the sirloin and offal was significantly lower than the threshold values for these elements, i.e., it accounted for 26% and 6.2% (liver)–19.5% (heart) of the allowable content of this element in pork meat and offal.
