Modified Atmosphere Packaging of Fennel

Abstract

Fennel was washed on the butt-end cut with ascorbic (1%) and citric (5%) acids and packed in polypropylene (PP) baskets sealed with PP film to generate a modified atmosphere. As a control, perforated PP was used. Storage conditions were 14 d at 0 8C followed by 4 d in air at 15 8C. Chemical and sensory quality attributes were monitored. No browning of external leaves developed. Modified atmosphere of 16 to 17% O 2 and 3 to 4% CO 2 was able to inhibit browning of the butt-end cut, the main factor for keeping quality of fennel, but treatments with antioxidants did not. In all treatments, green color and firmness decreased, although under modified atmosphere the best results for keeping fennel quality were found.

Step-by-Step Resolution of Singularities and Studying Interactions Between Them

“…Given coordinates x 1 , … , x n ∈ ℝ n , for which J p (a) takes on the Jordan form, then J p (a) is independent of at least one coordinate, which, without loss of generality, is x 1 . By combining this with the expanded Taylor formula, we obtain representation (5).…”

“…non-degenerated). Multiple singularities appear naturally in the context relevant to the bifurcation theory (see [1,5,10,15]) and, as such, have been studied by many authors using different techniques. The standard theoretical method allowing one to study multiple singularities is the so-called resolution of singularity (sometimes also called desingularization): under an appropriate transformation/deformation of the given map, one decomposes a compound singularity into simpler ones.…”

Application of Modified Atmosphere Packaging on Quality of Selected Vegetables: A Review

“…MAP treatment inhibited the activity of POD (32 with 55 u/min g FW for the control samples) and PAL (1.25 with 2.0 nmol/h g FW for the control samples). Artes et al ( 2002 ) in a series of experiments, looked into the treatment of fennel with ascorbic (1 %) and citric (5 %) acids, packed in PP baskets sealed with PP fi lm to generate a MA and stored for 14 days at 0 °C followed by 4 days in air at 15 °C. The use of antioxidant solutions did not affect the weight loss with samples in OPP having a signifi cantly lower weight loss compared to control (0.1 % and 3.5 to 3.9 % respectively) after cold storage.…”

Influence of Exposure to Light on the Sensorial Quality of Minimally Processed Cauliflower

“…Other factors such as calcium content (Conway and Sams 1987; Dong and others 2000; Soliva‐Fortuny and others 2002) and the presence of ascorbic acid compounds or other additives (Lamikanra and Watson 2001; Artés and others 2002; Piagentini and others 2002) have also been studied. However, only a very small number of studies in the bibliography make reference to the effect of exposure to light on the physiological response of MPV products.…”
