<p class="Default"><em>Hypsizygus tessellatus</em> is a popular wild edible culinary mushroom commonly cultivated in Japan, East Asia and North Europe. It is rich in micro nutrients and has great anti-tumorous, anti-cancerous rich polysaccharide fractions i.e. β-glucan, thus making it a good source of nutraceuticals. The present study was undertaken to investigate the nutritional as well as medicinal profile of this mushroom. Freeze dried and hot air dried samples were taken for the analysis. HPLC-RID investigations were carried out to estimate the content of β-glucan. The results revealed that it contains high proportions of protein (33.89g/100g), fiber (13.20g/100g), carbohydrates (50.10g/100g), potassium (1575mg/100g), calcium (98mg/100g) and phosphorus (568mg100g). The fat content was found to be 2.80gm/100g. Iron (18mg/100g) and zinc (5mg/100g) were present in trace amounts. Freeze dried fruit bodies showed better results than hot air dried samples pertaining to all nutritional and nutraceutical parameters. Value added products i.e. biscuits and salted crackers were made by incorporating 5 and 10% mushroom powder in refined wheat flour and their proximate, organoleptic and bioactive constituents were analyzed. Sensory evaluation based on hedonic scale resulted in high sensory ratings of all the products. The present study suggested that incorporation of 5% mushroom powder in salted crackers (<em>Mathri)</em> and 10% in biscuits not only increased concentration of protein, dietary fiber and β-glucan but also improved its flavor, texture and acceptability.</p><p class="Default"><strong>Keywords: </strong><em>Hypsizygus tesellatus</em>; lyophilization; hot air drying; salted cracker; biscuits; β-glucan</p>

<p>‘Murtilla’ (<em>Ugni molinae</em> Turcz) is a native Chilean species that belongs to the Myrtaceae family. It produces a small, globular fruit with pleasant flavor and recognized antioxidant activity. Convective hot-air and freeze drying are important techniques for fruit preservation, but their effect on murtilla fruit polyphenols and antioxidant activity has not yet been studied simultaneously. The objective of this study was to compare the effect of convective hot-air drying at 65 and 80 ºC and freeze drying on total polyphenol content (TPC), total anthocyanin content (TAC), polyphenols and anthocyanins of the Red Pearl-INIA variety of fresh murtilla fruits as measured by HPLC and antioxidant activity (DPPH and ABTS). The freeze dried fruit retained higher values for TPC (2192.4 mg/100 g d.w.), TAC (13.4 mg/100 g d.w.), polyphenols (79.02 mg/100 g d.w. by HPLC) and anthocyanins (0.188 mg/100 g d.w. by HPLC) than the murtilla dried by convective hot-air at both 65 and 80 ºC. The application of all treatments showed a positive increase in the DPPH (2945.4 to 3677.6 ?mol TE/100 g d.w.) and ABTS (2664.8 to 3397.2 ?mol TE/100 g d.w.) antioxidant activity of the dried murtilla compared to the DPPH (2111.1 ?mol TE/100 g d.w.) and ABTS (2247.8 ?mol TE/100 g d.w.) of the fresh fruit. Freeze drying was the best technique for the retention of polyphenols and antioxidant activity from the fresh murtilla fruit. Therefore, freeze drying is recommended over convective hot-air drying at 65 and 80 ºC when these bioactive compounds need to be preserved.</p>

AbstractDifferent drying methods, including hot air drying (HAD), freeze drying (FD), spray drying and vacuum drying (VD), were investigated to determine their influence on the chromatic coordinates, phenolics, anthocyanins and antioxidant activities of dried red raspberry (Rubus lambertianus). Pelargonidin-3-O-glucoside and catechin were found to be the main anthocyanin and non-anthocyanin phenolics, respectively, in fresh red raspberry. The most effective method for controlling browning was FD. The highest protective effects against bioactive compounds were observed in freeze-dried powders, when measuring the total anthocyanins, the scavenging of DPPH (1,1-diphenyl-2-picrylhydrazyl) and hydroxyl radicals and the inhibition effects on lard oxidation. HAD was effective for the preservation of total phenolics, while VD was useful for protecting catechin and procyanidin B1.

Palmyrah palm has great economic potential and every part of the palm is useful in one way or the other.The palm is found growing widely in southern states of India. The palmyrah products like tender fruit endosperm (nungu), neera, jaggery and tuber flour are not commercialised as the value addition in palmyrah is not standardised. Even though palmyrah is an economically important palm, it has not received proper attention from the agricultural research workers, probably on account of the fact that it is very slow growing palm found mostly in the wild state. In this context knowing of physico chemical properties and development of value added products and popularizing the same is essential.
