The development of value-added yogurt based on pumpkin peel powder as a bioactive powder
Get PDFThis study aimed to explore the utilization of pumpkin by-products as a bioactive powder in the development of value-added yogurt. Pumpkin peel resulting from food processing contains antioxidant components like phenolics, flavonoids, and carotenoids, compounds characterized by high bioactivity. This study investigated the potential of incorporating pumpkin peel powder (PPP) into yogurt to enhance its nutritional value and sensory attributes.
Results indicated that the incorporation of PPP into yogurt resulted in improvements in nutritional composition, particularly in terms of β-carotene and bioactive compounds. Additionally, the addition of PPP positively influenced the textural properties of the yogurt. The sensory evaluation revealed that the incorporation of pumpkin peel had no negative impact on the overall acceptability of the yogurt, with some samples (YPP2) even exhibiting preferred sensory characteristics compared to the control. The utilization of PPP as a bioactive powder in yogurt presents a promising strategy for reducing food waste and creating innovative, value-added dairy products. The development of such products can not only contribute to sustainable food production but also provide consumers with more diverse food choices with enhanced characteristics
Evaluation of in vitro protocols for effective regeneration of West African Theobroma cocoa (L)
Get PDFCacao is a perennial tree crop
from the Malvaceae family. It is made up of
twenty-one species, with Theobroma cacao
as the commonest and one of the most
economically important crops globally. West
Africa is the largest region of producers. Lack
of availability of planting materials all year
round has been a major factor besetting cocoa
production in West Africa and has led to a
drastic reduction in production in the last
decade. Establishing an efficient in vitro
protocol for germinating zygotic embryos of
local West African cocoa varieties offers a
solution to expedite large-scale planting
material production to enhance cocoa
sustainable production and material
availability. An effective in vitro protocol for
germinating zygotic embryos of local West
African cocoa varieties will help produce
large planting materials within the shortest
possible time and promote sustainable supply,
which could boost cocoa production within
the region and increase the availability of
planting materials. Four West African local
varieties of Theobroma cacao were cultured
in three explant types on both Driver and
Kuniyaki Walnut (DKW) basal salts and
Murashige and Skoog (MS) culture media
without growth regulators for twenty days.
The three explant types included seeds with
mucilage (SWM), seeds without mucilage
(SWtM) and embryo axis (EA). The cultured
explants were kept in a growth room of light
intensity with a temperature of 25 ℃ ±1,
relative humidity of 85% and the three
explant types responded differently.
Germination responses significantly varied
among the explant types. SWtM sprouted
earlier with more than 160 plantlets before
day 5, followed by EA with 150 plantlets
before day 5, while SWM showed the lowest
mean germination percentage of 8%
compared to SWtM and EA with 9% Early
sprouting was observed in the DKW medium
with almost 250 (34.72%) plantlets
development before day five compared to the
MS medium with less than 150 (20.83%)
plantlets development, but the MS medium
produces the optimal growth performance
with the best mean germination time of 0.08
per day, final germination percentage of
71.39%, and development of the growth
parameters leading to the development of
plantlets, including 2.60 for number of leaves.
This study shows that the media for in vitro
culture and the source of explants
significantly influence seed germination and
produce dissimilar effects on the germination
of zygotic embryos of Theobroma cacao
varieties. The study recommends using
SWtM on DKW medium for early sprouting
of seeds of Theobroma cacao followed by a
transfer into MS medium for seedling
development into plants
Strategii de dezvoltare a comunităților urbane durabile prin activități horticole
Get PDFPresent paper proposes a series of strategies as solutions that could increase food production while greatly reducing the environmental impacts of agriculture. From all agriculture activities, horticulture sector is characterized by a high biodiversity and is dominated by fruit and vegetable growing species.
Urban horticulture brings together what used to be widely separated: food production and urban space. Broadly speaking, urban horticulture includes everything from small home gardens, community lots to the management of city parks, rooftop gardens, as well as the vertical way of production.
This direction of production ensures increased availability of fresh products in big communities, raw material for processing, healthy diets, improved food safety, lower costs for transport, better use of resources, and mitigation on environmental impact of agricultural activities by reducing the emission of greenhouse gases
Distribuția unor aminoacizi in vinurile cu un continut scăzut de dioxid de sulf din podgoria Panciu
Get PDFIn wine industry, amino-acids play an important role in one of the most important elements of wine-making as fermentation and, as a result, are involved in specificity of wine variety. In the present study, specific wine verities from Panciu wine region were included, namely: Fetească regală, Fetească regală Frizzante, Cabernet Sauvignon and Cabernet Sauvignon rose. Every type of wines was processed by classic wine making methodologies but also with a different a modified scheme in order to compensate the role of low sulphur dioxide wine variants. Levels of amino-acids were determined by GC-MS, using a specific derivatisation method and ratio of intensities of peaks, permitted the quantification of 16 principal aminoacids. Some of aminoacids as alanine, glycine, valine, leucine, threonine, lysine and serine were highly affected in terms of decrease of concentration for low sufur dioxide wines. Proline which was resulted from the fermentation process had values higher than the average content of other aminoacids, from 1515.93 mg/L to 157 mg/L. Comparing the varieties with low and standard value of sulphur-dioxide, the levels of amino acids were differently affected. As a conclusion, the analysis of samples showed that the levels of amino-acids did not affect the overall quality of some the wines, the decreased levels can be associated with the transformation on other metabolites as biogenic amines
Caracterizarea consortiilor microbiene izolate de pe suprafața filmelor de polietilena de joasă densitate
Get PDFThe ability of microorganisms to transform or detoxify organic compounds is a well-known fact that promotes the development of environmental decontamination biotechnologies. The aim of this work is the characterization of the microbial consortium isolated from the surface of low density polyethylene films. LDPE films extracted from the soil were cultivated in liquid mineral salt media (MSM) with various composition and acidity. The microbial consortia isolated from MSM pH 5.5 and MSM pH 6.5 had a mixed composition. The analysis of the LDPE films by the FTIR method showed that the microorganisms, which populated the surface of the LDPE samples, cause chemical changes, observed on the absorption spectra of the films, such as the appearance of some absorption bands, or their splitting

The seedling growth response of Pisum sativum L. to different types of compost
No full textThe constant increase in the
high number of population, anthropogenic
and industrial activities are alarming issues
and raise food security issues around the
world. The treatment of compost acts as an
effective and environmentally friendly tool
for an increase in vegetable production. This
research article records the effects of three
soil compost treatments (1) dry leaves (Ficus
bengalensis L.), (2) solid waste (mustard oil
cake) and (3) chicken manure, alone and in
combination, with seedling growth
performances of pea in pot culture
experiments with five replications. The
results showed that soil compost treatments
showed a significant (p < 0.05) impact on
the physicochemical features of soil and the
physiological characteristics of pea (Pisum
sativum L.). Soil compost analysis revealed a
difference in soil porosity and pH, electrical
conductivity, organic matter, total organic
carbon, CaCO3, Na+, K+, phosphorous and
nitrogen. Plant tissue analysis of pea
seedlings also showed different levels of
sodium, potassium and phosphorous values.
The findings of the present research work
concludes that the treatment of F.
bengalensis dry leaves (25%) + garden loam
(75%) treatment produced maximum growth
performance, and the mustard oil cake solid
waste (25%) + garden loam (75%) treatment
showed the lowest seedling growth
performance. The F. bengalensis dry leaves
(25%) + garden loam (75%), soil compost
application treatment showed the maximum
seedling height of pea. The solid waste (SW)
mixed with garden loam (GL) (SW 25% +
GL 75%) and mustard oil cake solid waste
alone treatment showed the lowest seedling
growth of pea. The F. bengalensis dry leaves
25% + garden loam 75% compost treatment
also influenced on the soil properties

No full textEtiology of regenerative anemia in dogs and cats
Get PDFThe study was conducted between March 2020 – December 2022 on 129 dogs and 63 cats, different breeds and age,
both males and females, clinically diagnosed with anemia. All individuals were subjected to a full hematology test
including blood analysis and blood smear assessment where regenerative reaction was confirmed in 22 dogs and 9 cats.
To understand the ability of the hematogenous bone marrow to respond and develop new red blood cells (RBCs) and
the effectiveness of the therapy is important to recognize the main causes of anemia that lead to the destruction, loss or
deficit in production. The research highlighted post-hemorrhagic anemia as the most important cause of regenerative
reaction in dogs (68,2%) while in cats, hemolytic anemia was the primary reason of reticulocytosis (55,6%).
Correctly identifying the type of anemia in terms of hematogenous bone marrow responsiveness is of utmost
importance in tailoring the treatment, preventing complications or monitoring the progress of the patient and one of
main tools used to assess and differentiate between the RBCs disorders
Very-Low-Frequency Spike–Wave Complex Partial Motor Seizure Mimicking Canine Idiopathic Head Tremor Syndrome in a Dog
Get PDFCanine idiopathic head tremor syndrome (CIHTS) represents a benign condition characterized by episodic, uncontrolled movement of the head. Even though the condition might be an expression of a partial motor epilepsy, to date, there is a limited number of studies describing the electroencephalographic features. In this report, we describe the case of a dog diagnosed with partial motor epilepsy resembling CIHTS symptomatology, a new slow spike–wave complex pattern similar to that of Lennox–Gastaut syndrome in humans identified on electroencephalographic examination. We also studied the efficacy of phenobarbitone therapy over a period of two years
