Gum arabic was a more effective barrier than maltodextrin for bioactive compound retention. Results. When using gum arabic and maltodextrin as the carrier agents, the moisture results obtained for the spray-dried camu-camu powders were 2.8% and 3.2%, respectively; the process yield was 84% and 72%, respectively. Conclusions. The concentration factors for the vitamin C and phenolic compounds in camu-camu powder reveal the effectiveness of spray-drying to preserve the antioxidant capacity of this fruit. The optimal pressurized hot water extraction conditions were identified at: 91°C for temperature, 60 min for extraction time and 0.3 mL min− 1 for flow rate, giving a predicted concentration of 3.92 ± 0.30, 4.74 ± 0.32 and 0.357 ± 0.19 g per 100 g of dry powder for kaempferol, quercetin and vitamin C, respectively. Vitamin C is frequently incorporated into foods and premixes, and its concentration is declared on nutrition fact labels. Additionally, increasing focus on nutritional and functional properties of foods has led to growth of the dietary supplement industry in recent years.
Results of present study suggest that WEWS mainly containing vitamin C could be effective dietary source for reducing cytotoxicity and oxidative stress-induced heavy metals in HepG2 cell. This study followed 29 people over 12 months, and also found that swelling in the knees was also reduced. Most of the dried fruits and vegetables contain moisture 15 to 5 g/100 g sample, thus these two levels are used in this study. The experiments were performed into 3 moisture levels: one as its original state (moisture: 94 g/100 g sample) and others two were at its dried state (moisture: 15 and 5 g/100 g sample). However in order to reduce the experimental runs, higher temperature (20, 45 and 60 °C) did not use for samples containing moisture 5 g/100 g sample, vitamin c powder while lower temperature (−20 and −40 °C) did not use for the samples containing moisture 15 g/100 g sample. Original moisture content of the raw capsicum used in this work was 94 g/100 g sample and fresh samples were used in order to keep its original structure. The content of vitamin C was 42 mg from 100 g of dried powder. Ascorbic acid degradation was found to increase with increasing moisture content.
However, the degradation mechanism for ascorbic acid depends on several factors and is therefore specific for an individual system. Previous research has also demonstrated the effect of degradation products on deliquescence lowering and food ingredient stability. Deliquescence is a first order phase transformation from solid to solution that occurs at a certain relative humidity (termed RH0) that is specific to that crystalline solid, and has been linked with chemical stability of sensitive food ingredients. In particular, evidence has suggested that solid phase and solution phase ascorbic acid degradation differ, resulting in different end products. Vitamin C is added to foods as ascorbic acid or one of its salt forms (commonly sodium ascorbate or calcium ascorbate), or ascorbyl palmitate (a lipophilic form of vitamin C). Higher temperatures did not use for the fresh one since its structure degraded within few hours. Use the skincare tips to get rid of those blemishes or simply create a better overall look and live with healthier skin. One way to do your skin a favor is to avoid stress. Data points of storage were selected based on the degradation rate in different samples, since time frames of degradation in dried samples were much longer as compared to the fresh one.
Thus different time intervals (7-10 points) and total duration (19-155 days) were selected based on the rate of decay during different storage temperatures. The temperatures used for dried states were −40, −20, 5, 20, 45, 60 °C. Let’s hear what some of the moderators of the Deciem Chat Room have to say about L-Ascorbic Acid. For fresh capsicum, four levels of temperature used (20 °C, room temperature, i.e. normal storage; 5 °C, i.e. chilled condition; −20 °C, i.e. commercial storage, and −40 °C, i.e. industrial bulk storage or below commercial storage). Since vitamin mixes may be subjected to varying RH conditions during formulation, processing, packaging, storage, and distribution, an understanding of the impact of water-solid interactions on chemical stability within vitamin C powders is important for ensuring delivery of the vitamins in their primary active forms. The effects of co-formulation of these water-soluble forms of vitamin C with ascorbyl palmitate (P) (a lipophilic form of vitamin C) and dehydroascorbic acid (DHAA, a degradation product) on moisture uptake and vitamin C stability were also determined.
