An improved colorimetric method for determination of cyanide content in bitter almond oil was developed. The optimal determination parameters were as follows: volume ratio of hydrochloric acid to bitter almond oil (v/v), 1.5:1; holding time for hydrolysis, 120 min; and volume ratio of distillation solution to bitter almond oil (v/v), 8:1. Analytical results showed that the relative standard dev...

A microwave-assisted extraction (MAE) procedure to isolate phenolic compounds from almond skin byproducts was optimized. A three-level, three-factor Box-Behnken design was used to evaluate the effect of almond skin weight, microwave power, and irradiation time on total phenolic content (TPC) and antioxidant activity (DPPH). Almond skin weight was the most important parameter in the studied resp...

The activity of Prunus dulcis (sweet almond) β-glucosidase at the expense of p-nitrophenyl-β-d-glucopyranoside at pH 6 was determined, both under steady-state and pre-steady-state conditions. Using crude enzyme preparations, competitive inhibition by 1-5 mM imidazole was observed under both kinetic conditions tested. However, when imidazole was added to reaction mixtures at 0.125-0.250 mM, we d...

Background: Appendicitis leads to post-appendectomy pain with significant physical and mental implications, necessitating non-pharmacological management approaches. Objective: This study aimed determine which interventions can effectively reduce postoperative following an appendectomy. Design: A rapid review design was employed. Data Sources: The databases used were EBSCOhost-CINAHL PubMed. art...

Methylglyoxal (MGO) is recognized as being the bioactive component responsible for antibacterial activity of m?nuka honey. MGO content was investigated by high-performance liquid chromatography (HPLC-UV), in isocratic elution, to assess occurrence this compound mono- and multi-floral honey samples representative different botanical geographic origins Italy. Specifically, 110 from sweet cherry t...

The depletion of natural resources and the negative impact oil on environment have sparked interest in biodiesel as an alternative source energy. Indigenous vegetable oils potential to be used feedstocks. Transesterification produces biodiesel, which is regulated by numerous inputs factors, such catalyst dosage, temperature, speed, time while density specific gravity are outputs. Sweet almond (...

Recent projects in New England have shown that growing oilseed crops for on-farm biofuel production has the potential to increase the economic viability of farms through diversification. Oilseed meals would net the highest return if sold as a source of protein for a livestock ration, but there have been several barriers preventing the establishment of this market. There are small amounts of loc...

Kernels of Nonpareil almond and advanced breeding selections 23.5–16 and 23–122 were evaluated for similarities and differences in commercially important kernel characteristics. These three almond types did not differ in kernel mass, kernel length and width, nor in kernel color coordinates, luminosity and hue. Nonpareil kernels were observed to be significantly (p 6 0.05) thicker than kernels o...

Previous studies have provided evidence that the physical encapsulation of intracellular nutrients by cell walls of plant foods (i.e. dietary fibre) plays a predominant role in influencing macronutrient bioaccessibility (release) from plant foods during human digestion. One unexplored aspect of this is the extent to which digestive enzymes can pass through the cell-wall barrier and hydrolyse th...
