Effects of pomegranate juice and pomegranate peel powders on quality properties and antioxidant activity of pork sausage

Pomegranate juice is popular due to its unique health benefits, sensory characteristics and also a good source of bioactive compounds. Comparative study on processing effect of Not from Concentrate (NFC) and Reconstituted from concentrate (RFC) pomegranate juice on the nutritional and sensory characteristics of ‘Ganesh’ variant was conducted. Results showed that not much differences observed in parameters like pH, acidity, essential elements, protein, total sugars and polyphenol content between NFC and RFC. As per the study NFC had a better antioxidant activity with intracellular ROS inhibition of 11% higher with significant ( p < 0.05) than RFC in HepG2 cell lines. Total anthocyanin content was significantly different ( p < 0.05) in NFC (428.05 mg/l) compared to 326.74 mg/l in RFC expressed as cyanidin-3-glucoside. Iron uptake was 40 units (µg/mg protein) higher in NFC than RFC ( p < 0.05) in HepG2 cells. Sensory flavor profile showed NFC having significant differences with respect to characteristic pomegranate freshness, fruitiness, sweetness and astringency mouthfeel. RFC had higher sweetish and cooked flavor with additional vegetable like notes of beet and carrot. Based on the data better antioxidant activity, iron bioavailability, anthocyanin content and sensory attributes were captured in pomegranate NFC juices over RFC juices.

The polysaccharide based composite biomaterial (coating) used in preserving fruits and vegetables during storage is attracting increased attention as it is biodegradable material that prolongs shelf life. In the present investigation, chitosan–pullulan (50:50) composite edible coating was prepared with pomegranate peel extract (0.02 g/mL) as an active antioxidant agent. The effect of treatment with pomegranate peel extract enriched chitosan–pullulan composite edible coating on the shelf life of mango fruits during 18 days of storage period at room (23 °C) and cold (4 °C) temperature was evaluated. Results of the present study demonstrated that the application of chitosan–pullulan composite edible coating significantly (p ≤ 0.05) influences the storage life of mango fruits at both storage temperatures. The chitosan–pullulan composite edible coating reduced the physiological loss in weight (PLW), and maintained total soluble solids (TSS), acidity and pH of coated mango fruits as compared to the control. In addition, fruit sensory quality such as freshness, color, taste and texture were also retained by the treatment. Furthermore, sustained firmness, phenolic content and antioxidant activity confirmed the effectiveness of the pomegranate peel extract enriched chitosan–pullulan composite edible coating on mango fruits. The phenolic, flavonoid and antioxidant activity of coated fruits were retained by pomegranate peel rich edible coating. Therefore, the chitosan–pullulan (50:50) combination with pomegranate peel extract can be used as an alternative preservation method to prolong the shelf life of mango fruits at room and cold storage conditions. However, more in-depth studies are required at farm and transit level without affecting the postharvest quality of mango fruits, providing more revenue for farmers and minimizing postharvest losses.

The Impact

Abstract The industries of Pomegranate juice processing generate enormous waste in peel’s form which are suggested and evaluated as a supplement in animal feed but pomegranate peel have high percent of tannins, So the aim of this paper is to assess the impact of mixing pomegranate peel (PP), detanninated pomegranate peel (DPP) and pomegranate peel with polyethylene glycol (PEG) on the digestibility of nutrients, the yield of goats milk and its composition, feed conversion and some parameters of blood. Moreover, simple economic assessment of the examined rations are considered. Sixteen lactating Zaraibi goats of about 3-4 years old (in their 2nd to 4th of lactation seasons with an average body weight of about 25 + 0.5 kg are used in the present study. After 14 days of parturition was randomly assigned into four groups, four animals per each tested ration (R) for 90days, R1: Control : 50% CFM + 25% Egyptian clover and 25% wheat straw, R2: Control ration+1% PP, R3: Control ration+1% PP + 20 g (PEG) and R4:Control ration+1% DPP. The results revealed that the PP contained 90.85% DM, 4.84% CP, 15.53% CF, 87.21%OM, 4.69% EE, 62.15% NFE and 15.28% tannins. No significant differences were found between the tested rations regarding nutrients digestibility except EE digestibility. Nutritive values of R2 and R3 were slightly higher than R4 and R1, respectively. Ration three (R3) was the best ration for daily milk yield and total milk yield, where R4 showed the worst one. Also, there are no significant differences for dry matter, SV and TDN intake. While, values of DCP intake were higher significantly (P<0.05), for R3 and R2 followed by R4 then R1. Regarding feed conversion, R4 was superior to other tested rations followed by R1 then R3 followed by R2. All blood serum parameters were in the normal rang which support that the healthy effect of tested additives in goats rations. It seems that R2 and R3 could be used successfully for lactating goats, but R3 is very expensive from economical point of view, where R3 was negatively economical effect, and not recommended.

Simulated Digestion

Background: Pomegranate gained a widespread popularity as a functional food due to the high content of bioactive components of the whole fruit, as well as its juice and extracts. There is a large amount of research that assigns them very important functions for the human organism. Methods: The anthocyanins (ACNs) of pomegranate juice (PJ) from the Ermioni variety are quantitatively identified and their stability under a simulated digestion process (SDP) is investigated. ACNs, as well as phenolic compounds, were isolated through solid phase extraction and determined using high-performance liquid chromatography in every stage of the SDP. Total phenolics, total monomeric ACNs, polymeric color and antioxidant activity were also determined in pomegranate juice and during the digestion process. Results: The predominant anthocyanin was Cy-3-glucoside followed by the corresponding 3,5-diglucoside, which accounted for 40.8% and 27.4% of the total ACN content, respectively. About 65% of the total monomeric ACN content remained intact by the end of the simulated digestion process. Conclusions: The PJ of the Ermioni variety seems to retain a large amount of the bioactive compounds after the SDP. The antioxidant activity and total phenolic content (TPC) remain almost stable during the SDP, suggesting that the products formed during ACN degradation maintain the antioxidant activity of the parent molecule.
